5G for fixed connectivity in Cuba

ETECSA reports that over 110,100 Cuban households have DSL connectivity using their Nauta Hogar service. There are also shared facilites -- 986 WiFi hotspots (127 in Havana) and 347 Navigation Rooms (44 in Havana) with 1,309 computers (304 in Havana).

These services are dead-ends on the road to hoped-for "computerization." The Cuban population is around 11 million so, after three years, roughly one person in 100 lives in a Nauta home and the services are limited geographically since DSL is only available in the vicinity of telephone central offices and WiFi hotspots and Navigation Rooms are at fixed locations. Furthermore, the connection speeds are low and the prices high.

When the U. S. began making fixed Internet connections to homes, schools, businesses, etc., we had an installed inventory of relatively new last-mile phone lines, television cables, and longer fiber links and we have been expanding that infrastructure for forty years. Cuba does not have those assets and, even if they were willing to invite foreign investment, the gap would continue to grow. (Furthermore, I wouldn't wish a foreign monopoly or duopoly on anyone).

Could 5G wireless help with Cuban fixed connectivity?

Medium-Earth orbit (MEO) satellite Internet service provider SES has been providing Cuban international transit for two years, so they have an established relationship with ETECSA. SES also provides 2, 3 and 4G mobile backhaul and managed mobile service in places like Chad, Pakistan and Papua New Guinea. (They also offer WiFi hotspots as a service).

SES is planning to offer the same services plus focused small-cell connectivity for 5G networks when their next-generation mPower satellites come online. SES has 20 MEO satellites in orbit today and in 2021 they will be adding seven next-generation mPower MEO satellites with over 4,000 shapeable and steerable beams that can be switched under program control, giving the constellation over 30,000 dynamically reconfigurable beams and over 10 Tbps capacity. The mPower satellites will work in conjunction with their current MEO satellites and their geostationary satellites.

Expected Starlink coverage, mid-2020
How about using low-Earth orbit (LEO) satellites for 5G backhaul? Several companies are developing LEO Internet-service constellations, but SpaceX's Starlink constellation has a clear lead. Simulation of their announced plans shows that they will have coverage over Cuba by around the middle of next year and after that capacity will grow steadily as they launch new satellites. SpaceX plans to focus on the US market at first, but Elon Musk is an iconoclast who refused to serve Trump and I would encourage ETECSA to at least reach out to SpaceX.

So much for backhaul and system integration, how about connectivity to the thousands of local small cells that would be required for fixed broadband? That would require a lot of local fiber, which could be planned and installed by local people. Decentralization of the design and installation of the edge of a fixed 5G network would require more than capital and new technology -- it would require a political shift to a telecommunication policy focused on economic and social goals. Unfortunately, that seems less likely today than it seemed before the confiscation of SNET and other community networks.

Cuba is emphasizing and investing in mobile connectivity today and phones and tablets are fine for applications like content consumption, online shopping, social interaction, and Twitter-style politics, but businesses, schools, content creators, software developers, etc. need larger computers with fast, fixed connectivity. If Karl Marx were alive today, he might say mobile phones were the opiate of the people.

A 5G, community network strategy for Cuba (and other developing nations)

In a previous post, I suggested that Cuba might be able to leap over 4G to 5G wireless infrastructure using satellite and terrestrial networks for backhaul. While that would require political and policy change, it would be a good fit with Cuban culture and skills.

Before talking about Cuba, let me say a bit about wireless generations.

Each mobile technology generation used new technology and enabled new applications:
  • 1G: Voice calls
  • 2G: Digital data for text and sending small images
  • 3G: Smartphones for low-quality video, Web browsing, and GPS
  • 4G: High speed, lower latency communication for video streaming and chat and interaction with complex Web content
Fifth-generation wireless will be faster than today's 4G and latency is expected be on the order of 1 ms within the 5G network. Radios will be capable of beamforming -- rapidly switching focused beams among large numbers of devices -- and simultaneous two-way (full duplex) transmission at a given frequency. This will enable real-time applications like control of autonomous vehicles, remote medical procedures and augmented and virtual reality as well as fast file transfer and streaming and other, un-imagined applications.

Do not think of this as the evolution of the cell-phone network; think of it as a discontinuity in wireless communication to mobile and fixed users.

In addition to enabling new applications, each mobile computing generation uses different frequency bands and 5G is being designed to use very high frequencies. High-frequency radio waves enable high-speed transmission and small antennas. Being able to fit multiple small, cooperating antennas in a phone or other device (multiple inputs and outputs (MIMO) increases transmission range and speed. However, there is a high-frequency tradeoff -- low-frequency waves travel farther and are better able to penetrate obstacles like buildings and trees than high-frequency waves.

High-frequency networks will require a multi-tier architecture. With the current cellular network, phones and other devices communicate with a relatively distant base station that is connected by fiber or high-speed wireless to the Internet. Fifth-generation wireless will require many "small cell" radios that communicate with those high-capacity base stations.

Now back to Cuba (and other developing nations).

As of last year, there were 879 cellular base stations in Cuba, 358 of which had been upgraded to support 3G communication. As of 2016, 85.3% of the population was covered by 2G cellular and 47% of the population had 3G coverage. (Note that 2G coverage has barely increased since 2010 and it has been flat since 2012). If they continue rolling out 3G, it should reach the 85.3% fairly soon, but new base stations will have to be added to cover the entire population.

Upgrading from 2G to 3G requires new equipment and also more backhaul capacity between a base station and the Internet because 3G transmission speeds are greater than 2G and 3G applications use more data. For most Cubans, it would also require the purchase of a new phone. High-speed, 5G service would require much more backhaul capacity and new phones.

In densely populated areas it will be economically feasible to provide that backhaul using fiber, but fiber to support 5G capacity throughout the island would be very expensive. In many locations, satellite connectivity may turn out to be a better backhaul medium than fiber. SES Networks (O3b) will be offering connectivity using their middle-Earth orbit satellites before Cuba is ready for 5G and by the time they are ready, low-Earth orbit satellite connectivity from vendors like OneWeb and SpaceX Starlink will be available.

But what about the large number of small-cell radios that be feeding 5G base stations?

Like today's WiFi radios, they will be installed and maintained by community members and users. Cubans are known for do-it-yourslef innovation, for example in keeping old cars running and installing motors on bicycles and they have built community networks in places like Gaspar, Camagüey and Pinar del Río. Havana's SNET, is said to be the largest community network in the world that is not connected to the global Internet and there are over 8.000 amateur radio operators and over 1,400 active, self-employed programmers in Cuba.

Small cell radios will be semi-automatically configured and simpler to install and maintain than the WiFi radios used in today's street nets, but that is the easy part. Decentralized technology calls for decentralized decision making. Local people who are locally elected should decide questions like how many small cells to deploy in a neighborhood or rural area, where they should be located and how to pay for them. Would the current municipal electoral districts (from 200-3,000 inhabitants) be an appropriate locus of network control?

ETECSA would cede local control but be responsible for acquiring international bandwidth and providing backhaul over fiber or satellite from their base stations. They would also serve as consultants to local communities and could negotiate high-volume discount purchases of locally-owned equipment.

Note that I am still assuming a major role for ETECSA in spite of the fact that historically, nations like Cuba have privatized telecommunication and licensed foreign operators in exchange for investment in infrastructure. In previous posts I have suggested that vested interest and bureaucracy at ETECSA and uncertainty over control may be stifling Cuban Internet expansion. To the extent that that is the case, the new administration would have to change the organizational culture to focus on Cuba's stated economic and social policy goals -- leapfrogging current regulation and policy along with the technology. That may be wishful thinking, but if they are able to do so, they will have an advantage over nations in which private company profit trumps (no pun intended) social goals.

The technology is also ill-defined and unproven. While the standard for the first version of the 5G radio interface between a device and base station is complete, other hardware and software standards are still being developed and 5G is based on technologies that have been tested in trials, but not in large scale practice. The first deployments are not expected until next year, user and network equipment prices are not set and competing technologies like Starry may impact pricing and deployment.

Novel, unproven 5G wireless technologies (source)

In spite of this policy and technology uncertainty, ETECSA can start the ball rolling today by cooperating with and providing Internet gateways to SNET and other street nets, possibly in conjunction with support of the Internet Society and the Organization of American States. They can also learn from the experience of others like Gufinet in Spain and a variety of community networks in the US and elsewhere. At the same time, they should be following the 5G standards process directly and through their vendors, primarily Huawei and SES Networks (O3b), in order to plan for the future.

SpaceX Starlink and Cuba -- a match made in low-Earth orbit?

I've suggested that Cuba could use geostationary-orbit (GSO) satellite Internet service as a stopgap measure until they could afford to leapfrog over today's technology to next-generation infrastructure. They did not pick up on that stopgap suggestion, but how about low-Earth orbit (LEO) satellite Internet service as a next-generation solution?

SpaceX, OneWeb, Boeing and others are working on LEO satellite Internet projects. There is no guarantee that any of them will succeed -- these projects require new technology and face logistical, financial and regulatory obstacles -- but, if successful, they could provide Cuba with affordable, ubiquitous, next-generation Internet service.

Cuba should follow and consider each potential system, but let's focus on SpaceX since their plan is ambitious and they might have the best marketing/political fit with Cuba.

LEO satellite service will hopefully reach a milestone this week when SpaceX launches two test satellites. If the tests go well, SpaceX plans to begin launching operational satellites in 2019 and begin offering commercial service in the 2020-21 time frame. They will complete their first constellation of 4,425 satellites by 2024. (To put that in context, there are fewer than 2,000 operational satellites in orbit today).

SpaceX has named their future service "Starlink," and, if Starlink succeeds, they could offer Cuba service as early as 2020 and no later than 2024 depending upon which areas they plan to service first.

What has stopped the Cuban Internet and why might LEO satellites look good to Cuba?

Cuba blames their lack of connectivity on the US embargo, but President Obama cleared the way for the export of telecommunication equipment and services to Cuba and Trump has not reversed that decision.

I suspect that fear of losing political control -- the inability to filter and surveil traffic -- stopped Cuba from allowing GSO satellite service. Raúl Castro and others feared loss of control of information when Cuba first connected to the Internet in 1996, but Castro is about to step down and perhaps the next government will be more aware of the benefits of Internet connectivity and more confident in their ability to use it to their advantage.

A lack of funds has also constrained the Cuban Internet -- they cannot afford a large terrestrial infrastructure buildout and are reluctant (for good and bad reasons) to accept foreign investment. SpaceX is building global infrastructure so the marginal cost of serving Cuba would be near zero.

They say that the capital equipment for providing high-speed, low-latency service to a Cuban home, school, clinic, etc. would be a low-cost, user-installed ground-station. I've not seen ground-station price estimates from SpaceX, but their rival OneWeb says their $250 ground-station will handle a 50 Mbps, 30 ms latency Internet link and serve as a hot-spot for WiFi, LTE, 3G or 2G connectivity.

Since the marginal cost of serving a nation would be small and they hope to provide affordable global connectivity, I expect their service price will vary among nations. Prices would be relatively high in wealthy and low in poor nations -- there would be no point in having idle satellites flying over Cuba or any other place.

Expansion of the Cuban Internet is also constrained by bureaucracy and vested financial interest in ETECSA and established vendors. While I do not endorse Cuba's current monopoly service and infrastructure ownership policy, it could remain unchanged if ETECSA were to become a reseller of SpaceX Internet connectivity.

In summary, if Starlink succeeds, they could offer affordable, ubiquitous high-speed Internet, saving Cuba the cost of investing in expensive terrestrial infrastructure and allowing ETECSA to maintain its monopoly. The only intangible roadblock would be a loss of control of traffic. (But Cuban propagandists and trolls would be able to reach a wider audience :-).

That is the rosy picture from the Cuban point of view, what about SpaceX?

OneWeb plans to offer LEO satellite Internet service in Alaska in 2019 and hopes to cover all of Alaska by the end of 2020.

How about SpaceX starting by serving Cuba?

I don't know the SpaceX constellation rollout plan, but satellites that serve Cuba would also be capable of serving the eastern US and FCC licenses are conditional upon providing US service in a timely manner.

Since Cuba is an island nation, portions of the footprint of satellites serving Cuba would fall on the uninhabited ocean. That would reduce population destiny in the satellite footprint area, freeing capacity for use by customers in relatively urban areas.

Selecting Cuba as its initial service market would be an audacious move, but Elon Musk is not a conventional, conservative businessman. SpaceX would get a lot of publicity from a Cuba opening and, like the roadster they just launched into orbit, first offering Starlink service in Cuba would have symbolic value -- marking an opening to Cuba.

There is pent-up demand for Internet access in Cuba since they have very poor Internet access given their level of education and development.

Cuba is 166th among the 176 nations the International Telecommunication Union (ITU) ranks on access to telecommunications. Haiti, ranked 167th, is the only nation in Latin America and the Caribbean (LA&C) that ranks below Cuba, yet Cuba ranks 9th in the region on the ITU telecommunication-skills index. Cuba ranks tenth in LA&C on the United Nations Development Programme's human-development index and their mean years of schooling is the highest in the region.

Cuba's relatively high human-development and IT-skill indices reflect its emphasis on free public education at all levels. This is exemplified by the curriculum at Cuba's Information Science University, where students pay no tuition but are required to work on useful applications in education, health, sport, and online government.

But, perhaps the biggest contributor to pent-up demand is El Paquete Semanal, a weekly distribution of current, pirated Internet content that is distributed throughout the nation. I've heard the claim that 95% of Cubans see El Paquete content each week. That sounds high, but it is very popular and has been alleged to be Cuba's largest private employer.

The political situation is the elephant in the room. The US has formed a Cuba Internet Task Force and Trump is following President Obama's lead in seeking to strengthen the Cuban Internet, so it unlikely that the US government would object to SpaceX offering Starlink service to Cubans.

That being said, such a move would be unpopular among some members of Trump's Cuban "base." While there might be some domestic political cost to SpaceX, an opening to Cuba would be seen as extremely positive in Latin America and the rest of the world and SpaceX and Tesla are global companies. (Only Israel supports the US embargo of Cuba).

If you guys want to talk about this, DM @RaulCastroR and @elonmusk.

Update 2/27/2018

Two years ago, Google invested $900 million in SpaceX, stating that they expected the acquisition would be used “to keep Google Maps accurate with up-to-date imagery and, over time, improve Internet access and disaster relief.”

In the aftermath of Hurricane Maria, Google began providing mobile phone and Internet connectivity in Puerto Rico using their Project Loon balloons and today they are serving 200,000 Puerto Rican users. They have learned from this effort and demonstrated the ability to provide Project Loon connectivity. How about using Starlink when it is available?

Starlink envisions low-cost, user-installed terminals at homes and other end-user sites, but their satellites will also have to connect to ground-stations and it turns out that Google has a lot of terrestrial points of presence on the Internet. Some of them are shown on the following map:

Google Global Cache locations(source)

Note that one of those points of presence is in Havana and two others are in Puerto Rico.

SpaceX rocketry, Starlink satellites and service plus Google's terrestrial infrastructure sounds like a formidable combination -- perhaps too formidable. A part of me would love to see such a combination succeed and eventually provide a truly global Internet, but I am also afraid of the market and political power that enterprise would have. Would this or any other global Internet service provider require unique regulation and, if so, what should it be and who has the power to do it?

If a global ISP monopoly (or even an oligopoly) doesn't worry you, what about adding strong AI -- is the Earth beginning to grow a nervous system -- with us as biological components (for the time being)?

Update 3/20/2019

SpaceX sister company, SpaceX Services, filed an FCC application for "a blanket license authorizing operation of up to 1,000,000 earth stations that end-user customers will utilize to communicate with SpaceX’s LEO constellation." Those end-users will be individuals, libraries, schools, etc. "throughout the contiguous United States, Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands." SpaceX will begin launching operational satellites this year, and those that provide connectivity over the US east coast and Puerto Rico will have idle capacity when in sight of Cuba. Cuba isn't politically ready to allow home connectivity, but how about satellite links to Youth Clubs, schools, clinics, libraries, etc.? It would be legal from the US side and the sort of thing Elon Musk might like to do.

Update 12/30/2019

Elon Musk confirms that Starlink Broadband should be available in the Caribbean in 2020 or early 2021. See more here. How about a ground station at Google's data center?

Cuban satellite connectivity -- today and (maybe?) tomorrow

Last January, Doug Madory of Dyn Research reported on Cuban traffic, noting that C&W's share had increased:


Yesterday Madory reported that ETECSA had activated a new internet transit provider, medium-Earth orbit (MEO) satellite-connectivity provider O3b Networks (Other 3 billion), replacing geostationary satellite provider Intelsat:


(They have also added Telecom Italia, which, until 2011, owned 11% of ETECSA, but I will save that for another post).

O3b's MEO satellites orbit at an altitude of around 8,012 km above the equator while Intelsat's geosynchronous satellites are at around 35,786 km, therefore the time for a data packet to travel from earth to an O3b satellite and back to Earth is significantly less than to an Intelsat satellite. This move to O3b may be related to ETECSA's recent decision to offer SMS messaging service to the US (at an exorbitant price) and it will surely improve the speed of interactive applications.

That is today's situation as I understand it, but now I want to speculate on the future of Cuban satellite connectivity -- say in the early 2020s.

First a little background on O3b Networks. O3b is a wholly owned subsidiary of SES but it was founded in 2007 by Greg Wyler, who has since moved on to a new venture called OneWeb. While O3b provides service to companies like ETECSA, OneWeb plans to also provide fast global connectivity to individuals in fixed locations like homes and schools as well as the "Internet of things."

This animation was prepared by Teledesic,
formed in 1990 to provide LEO satellite
connectivity. Teledesic failed, but
technology, the market and executive skill
have changed since that time.
OneWeb plans to connect the "other 3 billion" people using a constellation of around 1,600 satellites in low-Earth orbit (LEO) at an altitude of 1,200 km and another 1,300 in MEO at 8,500 km. They are working with many vendors and partners and plan to launch their first satellites in March 2018. They will begin offering service in Alaska in 2019 and hope to cover all of Alaska by the end of 2020. By 2025 they expect to have 1 billion subscribers and their mission is to eliminate the global digital divide by 2027.

Now, back to Cuba. ETECSA is doing business with Wyler's previous company O3b. Might they also be talking with his current company, OneWeb? It takes time to launch hundreds of satellites, so service is being phased in -- might Cuba come online sometime after Alaska? By connecting Cuba, OneWeb would gain publicity, the goodwill of many nations and access to a relatively well-educated, Internet-starved market and it would enable Cuba to quickly deploy broadband technology.

As I said, this is pure speculation. OneWeb faces significant technical, business and political challenges and may fail. Politics would be particularly challenging in the case of Cuba. Both the US and Cuba would have to make policy changes, but maybe the time is right for that -- the Cuban government will change in 2018 and the US government is likely to change in 2020 when Alaska comes online.

OneWeb has established an indirect relationship with ETECSA through O3b, but other companies, including SpaceX and Boeing, are working on similar LEO projects. Might ETECSA be talking to the others?

SpaceX is particularly interesting. Theirs is the most ambitious plan and their experience as a rocket company is invaluable. Less tangibly, founder, CEO and lead designer Elon Musk is known for audacious risk-taking. OneWeb will begin with Alaska -- might SpaceX begin with Cuba? In serving Cuba, they could also serve the Eastern US and since Cuba is an island the footprint of a satellite would not be so densely populated. SpaceX would gain publicity and international political good will.

To learn more, see this survey of LEO satellite plans and related issues.

Update 2/27/2018

SES subsidiary O3b has gone public with their agreement to route ETECSA traffic and Doug Madory has updated the route graph (above) that he provided when he first noticed the link last December.

The following graph shows that O3b now accounts for about 5% of ETECSA's routes and, as in December, geosynchronous satellite provider Intelsat is gone. Latency over the O3b link will be much lower than it had been with Intelsat, so some users will see improved performance.


A friend tells me that the O3b ground station is about 25 miles east of Havana in Jarusco -- the location of the original Soviet Carib 1 ground station in 1974.

The possibility of a uniquely Cuban Internet

This post is not about what I think will happen, but to begin discussion of what the Cuban government could do if the goal were to provide a modern, open Internet with affordable (free in some cases?) access.

The Cuban Internet is in a sorry state. Freedom House ranks Cuban Internet freedom 62nd among the 65 nations they survey and the UN International Telecommunications Union ranks Cuban information and communication technology development last among 32 nations in Latin America and the Caribbean.

Historically, there are three primary causes for the sad state of the Cuban Internet -- the US trade embargo, Cuban poverty at the time of their connection to the Internet and the government's fear of information. (We'll discuss a possible new constraint, ETECSA, later).

President Obama has lifted the first barrier and, when we look at other poor Latin America and Caribbean nations, we see that Cuba could afford a better Internet than it currently has.

That leaves fear of an open Internet. The government says the Internet is a priority and they want to expand access as quickly as financially feasible. I am skeptical, but let’s assume they are sincere – what might they do in the short term and the long term?

In the short term

Cuba cannot afford ubiquitous, modern Internet infrastructure today – they need low-cost interim action while planning for the long term. Here are some low-cost ways they could improve the Internet in the short run:


What about the long term?

Long range planning, addressing technology and, more important, infrastructure ownership and regulation policy, should begin immediately.

Cuba has little Internet infrastructure. There is an undersea cable to Venezuela, but little fiber on the island. (Eventually, Cuba might take control of the cable being installed between Guantánamo and Florida). Nearly all home connections are dial-up and the cell network is obsolete 2G technology. There are 573 public access computers in 155 locations, but they are slow and an hour online costs nearly a week’s pay for many workers.

Cuba should leapfrog today’s technology, looking toward developments that are five or more years out – 5G  mobile communication, high frequency wireless by Google and others, the satellite constellation projects from SpaceX and OneWeb, connectivity using an undersea cable from Havana and perhaps the one at Guantánamo, etc. Routing traffic using version 6 of the Internet protocol will prepare them for the “Internet of things.”

The long range planning of technology is necessary, but formulating policies for ownership of infrastructure and regulation is more important -- not only for Cubans, but for the rest of the world as well if the Cuban experience leads to innovative policies.

The conventional wisdom is that Cuba should invite foreign companies to install infrastructure – a path many developing nations have followed with marginal success. It is not certain that Cuba, with its current government and weak economy, could attract foreign investment, but even if could, I would hate to see Cuba's Internet future in the hands of companies like AT&T or Orange.

If they do go with foreign investment, I would not be surprised to see them partnering with Google rather than a traditional ISP – Google executives have visited Cuba and Google is clearly interested in global connectivity. My experience in the US leads me to trust Google to do a better job than the incumbent ISPs, but, I would still have to ask -- in the long run, why should we expect Google to be better for the Cuban people than a traditional ISP? (I'd ask the same question of aspiring global satellite ISPs SpaceX and OneWeb).

Cuba should go slowly and consider a broad range of infrastructure ownership policies like municipal ownership in Stockholm, government as a venture capitalist in Singapore, government as rural wholesale backbone provider as in India, individual ownership of final links, etc. Cuban policy makers should consider a broad range of policy models -- Chile, Iceland, Vietnam, Estonia, etc. etc.

In 1997, fear of free speech led the government to squelch the Internet, but today there is another potential stumbling block – ETECSA, Cuba’s monopoly Internet service provider. ETECSA is usually described as a state-owned monopoly, but it’s privately owned by a murky collection of investors (rumored to include Fidel and Raúl Castro) and regulated by the Ministry of Communication.

The relationship between ETECSA and the Ministry is unclear – which organization makes investment decisions, sets prices, gets the profits or absorbs the losses, etc.?

Cynics predict the Cuban Internet will undergo a Soviet-style sell-off to foreign investors who will run it for their profit. But, if the Cuban government sincerely embraces its socialist goals, it has a chance to create a uniquely Cuban Internet with the goal of providing universal, affordable access to its citizens rather than making profit for private ISPs, ETECSA or the government. I’m skeptical, but hope I’m wrong.

Update 3/18/2015

One of my long-term suggestions was that Cuba keep an eye on OneWeb, which hopes to provide global satellite connectivity. CEO Greg Wyler, speaking at the Satellite 2015 Conference yesterday, said they hope to be offering service by 2019 -- providing $250 ground stations that require no setup and establish a 50 mbps connection to the Internet and a WiFi, LTE, 3G and 2G local area network.

One of my short-term suggestions was that Cuba deploy geostationary satellite ground stations. They could do that today, but, if OneWeb is successful, their satellite links will be cheaper and superior to today's satellite offerings in every way.

Grag Wyler speaking:


A OneWeb ground station -- no setup required:

Update 3/22/2015

It seems that Internet access at the University of Santiago de Cuba has been significantly improved. I am being a vague because the post I read has been translated into English and is hard to follow. It sounds like the university now has a fiber link and speed and data caps have improved significantly.

Can someone fill me in on the details of this upgrade and on the general state of connectivity at Cuban universities?

-----
Update 3/28/2015

Ricardo Alarcon, head of the Ministry of Higher Education announced a deal with ETECSA to substantially improve university Internet access. It sounds like every university will have both domestic and international links. The article is vague and inconsistent on technical details, but it also says students will have access to 40,000 digital magazines -- double the previous amount.

The article also refers to an upgrade to the university network, REDUNIV. The figure below was taken from a PowerPoint presentation last updated in 2005. I am saddened to see a frame relay backbone, but I am sure it has been upgraded since that time. Does anyone have information about the current network?


-----
Update 5/11/2015

I suggested that Cuba would be better off owning and controlling their telecommunication infrastructure rather than turning it over to foreign investors and they may be heading in that direction.

Lina Pedraza Rodríguez, Cuban Minister of Finance and Prices, said that Cuba is in "very advanced" negotiations with Huawei at the World Economic Forum on Latin America last week.

Pedraza also said the Cuban telecoms sector would be open to all foreign companies but also noted that the country wanted to avoid the "negative parts of the Internet."

Pedreza also feels that things are moving slowly with the US and called for the elimination of our trade embargo.


-----
Update 5/28/2015

One of my short-run suggestions was to legitimatize and support shared WiFi hotspots. Raymond J. Delgado Sutil has written a post that elaborates on that suggestion. He estimates that ETECSA's revenue from Internet access "navigation rooms" is around 907,000 CUC per year and the cost of installing WiFi access points at each navigation room and Youth Computer Club location would be about $200,000. Users would use their own computers and phones, eliminating the need for more computers in the navigation rooms. He says ETECSA should "just do it" rather than conducting a "study."

Unfortunately, Delgado does not mention backhaul speed at the navigation rooms or whether they connect to the undersea cable for international traffic. The backhaul speed is only 2 mb/s at the ballyhooed free hotspot of the artist Kcho. At that speed, performance would be very poor whether access was over WiFi or using one of the original hard-wired computers. Similarly, if international access were routed over satellite, response would be very slow.


-----
Update 7/16/2015

Raul Castro has reported that Cuba's economy is growing at a 4.7 percent annual rate (due to increased tourism?) and Cuba is "strictly meeting its debt obligations with foreign creditors and suppliers." A stronger economy will enable Cuba to pursue a relatively independent Internet strategy, without excessive reliance on foreign investment.


-----
Update 7/18/2015

Speaking at the 10th Congress of the Young Communist League of Cuba, Deputy Minister of Communications Jose Luis Perdomo said they were working on connectivity from homes, lower costs, access from educational, health, scientific, cultural and sport centers as well as industrial, business and service centers.

More concretely, he said they planned provide Internet service to 3G cellular users and deploy WiFi in Havana and provincial capitals. There is little 3G cellular today -- does that mean they plan to extend it? He also said they were deploying IPv6.

Deputy Minister of Communications Jose Luis Perdomo

-----
Update 11/19/2015

We suggested that Cuba shift to IPv6 and, as the following figure shows, they are routing IPv6 traffic over Tata and Newcomm (satellite) networks, but not Telefonica. I believe the "other" traffic is internal to Cuba -- peering with CENIAI Internet (AS10569).


-----
Update 1/17/2016

In considering future technology, infrastructure ownership and policy options, Cuba should look at the experience of others. Steve Song has just posted his annual Africa Telecoms Infrastructure review. The review might provide some insights for Cuban policy makers and they should be consulting with folks like Steve Song.


-----
Update 9/29/2016

Hybrid fiber-wireless
is another future technology Cuba should track. Google, cell phone companies and others are experimenting with a number of options for "last kilometer" technology. One in particular, PCell wireless, might turn out to be appropriate in Cuba if it proves to be practical.

Demonstrations of PCells in labs are impressive, allowing full speed wireless connections to computers or mobile devices that are inches apart. One would expect closely situated radios operating in the same frequency band to interfere with each other, but PCells capitalize upon interference, analyzing it to create very small zones of clear reception.

It remains to be seen how this technology works on the street as opposed to the lab and Webpass, a boutique high speed Internet service provider that was recently acquired by Google, and Nokia are both evaluating PCell technology. If it turns out to be effective, PCell might be particularly appropriate in Cuba with its penchant for do-it yourself improvisation.

PCell access points are small and distributed compared to conventional cell towers and, if they turn out to be effective, they could be installed by the people -- like a "street net." They remind me of the home-made dishes people used to pirate TV signals broadcast from the Havana Libre hotel back in the day and the installation of local area network wiring in California schools by students and staff during "Net Days."

In this post, I have suggested several short-run, interim steps Cuba could take while evaluating and planning for leapfrogging to next-generation infrastructure when they are financially and politically ready to create a modern Internet. I wrote the post about a year and a half ago, and started by saying that it was what I hoped would happen, not what I expected to happen.

There have been some short-run improvements during the last 18 months, but not all that I had hoped for. I have no idea what, if any, plans have been made for leapfrogging to next-generation infrastructure -- the planning process is not open or transparent.

One thing is for sure -- there will be no leapfrogging on infrastructure without leapfrogging to next-generation policy on infrastructure ownership and regulation. Next generation policy should be geared toward meeting economic and social goals, not to maintaining telecommunication bureaucracy and revenue or on politics. As we see below, the world is trending in that direction.

Global trend toward 4th generation regulation, based on social and economic goals

And, fourth generation regulation is correlated with broadband connectivity:
