I don't criticize to knock the system down. On the contrary, I criticize to perfect the system.
Carlos Alberto Pérez
This post has taken several twists and turns.
I started out to write a post commenting on an ETECSA PowerPoint presentation on their plan for home Internet connectivity. The presentation had been leaked by Carlos Alberto Pérez on his blog Chiringa de Cuba on June 23. (The presentation is supported by another document leaked by Pérez, an
Executive Summary of a National Strategy for the development of broadband connectivity infrastructure in Cuba -- English translation
here). In addition to some analysis of the plan, I was going to discuss the role of Chinese equipment suppliers, predominantly Huawei.
Then, on June 25, ETECSA
denied the validity of the leaked document, saying it was used only for training. They said the tentative prices shown were incorrect, but did not retract the substance of the presentation, which shows a plan to provide DSL service to some Cuban homes using Chinese equipment.
That denial was followed by the blocking of access to Pérez' blog, presumably because he had published the leaked document.
They subsequently restored access to the original post, but to be safe,
I have put a copy here, and invite people to add comments to it. There is also a backup of the Strategy document
here. (As they say, information wants to be free).
I will provide my reactions to the leaked document here and save the reflections on the Chinese role for a second post.
The presentation says ETECSA plans to roll out asymmetric (faster download than upload) DSL service using Chinese equipment in an unspecified number of central offices. As we see in the following leaked slide, they will use
Huawei ME 60 gateways between the phone and IP networks and have ordered 15,000
TP Link TD 8840T modems for homes. I do not know, but it seems reasonable to guess that the digital multiplexers (DSLAMs) installed in the central offices will be from Huawei as well. (I'll get to the question marks later).
The following price slide was included in the presentation, but ETECSA has said this was only a place-holder for training purposes and I will take them at their word -- consider these prices only as possibilities:
These prices may be higher than we eventually see, but there will surely be a significant number of people who cannot afford a DSL connection so we can imagine people sharing accounts and a black market for reselling time.
The following slide differentiates between national and international access, so I presume that the actual prices will take that into account. That would be reasonable since most international access will be over congested satellite links. The slides say nothing about which, if any, international sites will be blocked.
The above slide also differentiates speed levels, times of day and days of the week. I suspect the actual pricing will take time and day into account, but that may or may not be the case for the different speeds that are shown. Varying infrastructure will cause speed differences regardless of price.
Before a home can receive DSL service, the equipment in the central office serving it must be upgraded and a relatively short, high quality phone line must run between the home and its central office. (That is one of the question marks in previous diagram).
Cuba reported 3,882,424 private homes (
2012) and 939,500 residential phone lines. That means around 2.9 million homes would have to be wired before they could have Internet service. The presentation says they will give priority to homes that already have land lines and those belonging to the self-employed. (The former is obvious and the latter interesting).
Cuba reports having 688 central offices (
2013), few of which contain DSL equipment. Most would have to be upgraded in order to provide DSL service.
Once connected, what will be the data transmission speed? The above slide shows asymmetric (down/up) connection speeds ranging from 128/64 to 8,192/768 kb/s. With DSL technology, transmission speed depends upon the distance of a home from its central office and the condition of the copper lines connecting them. These are always best effort numbers -- "up to" the stated speeds.
Let me give an example, I live Los Angeles and Google Maps says I am 1.1 mile from my central office. Verizon offers me two service levels: "high speed" DSL service is .5-1 mb/s and "enhanced" service is from 1.5-3 mb/s, for an extra $10 per month. To be fair, the copper in my neighborhood is 70 years old, but I doubt that many Cuban customers will be able to get 8,192 kb/s.
There is also a slide showing day/night and weekday/weekend traffic patterns. Judging from the y-axis, I am guessing that this is showing international traffic, which is heavy during week days. Before a user logs on, he or she will be able to measure their current connection speed before starting a session and using their hours.
The Internet connection is the second question mark in the previous diagram. What are the connection speeds between the central offices and the Internet? In the US, central offices are connected by high speed fiber, but I know little about Cuba. For example, in Havana, some or all central offices may be connected to a fiber backbone, but what of the link from there to the Internet? Havana is far from the undersea cable landing to the east, so I imagine those links are via congested satellites.
The bottom line is that this is an early step toward modern home connectivity using yesterday's technology and
I hope Cubans are planning to leapfrog today's technology in the long run.
Well, that is a little tea reading from the leaked slides. It is too bad that the situation is so opaque that we have to guess about ETECSA and their plans and it is even worse that they seem to have blocked Pérez' blog. He is an asset, not a threat --
as he has stated "I don't criticize to knock the system down. On the contrary, I criticize to perfect the system."
I think the involvement of Chinese suppliers is more interesting than this leak, and I will take that up in a subsequent post.

Update 6/29/3025
Ted Henken told me that the problem with accessing Chiringadecuba.com may not have been government blocking but expiration of the domain name, and it seems he was correct.
I did a whois lookup and it turns out the domain expiration date was 2015-06-26. I then checked at the registrar, Name.com, and saw that chiringadecuba.com is not available. It sounds like it may have expired, but they are giving Perez a grace period within which to re-activate it. Since he would not have a US credit card, there may be some difficulty with that.
-----
Update 6/29/2015
Chiringadecuba.com is online again and the expiration date has been extended till next year. My apologies to ETECSA for fearing that they may have blocked access.

Update 1/27/2016
Huawei
has tested their new technology,
g.fast, in Panama. The technology trial ran for two months and they achieved speeds averaging 500 Mbps to download and 150 Mbps to upload, over existing copper lines.
I wonder if that is the technology they will be deploying in Cuba and how it will perform over Cuban infrastructure.
-----
Update 2/1/2016
ETECSA has announced a pilot home connectivity project in two Havana neighborhoods. The
Associated Press report says Cubans in Old Havana will be able to "order service through fiber optic connections operated with Chinese telecom operator Huawei."
I would be surprised if they are talking about fiber to the premises -- hybrid fiber/copper is more likely. They also said they would being allowing cafes, bars and restaurants to begin ordering broadband service. No dates or prices were given.
I have also heard from a reader that some casas particulares are offering Internet connectivity in Havana, but I do not know how they are connected or at what speed and cost.

Update 2/11/2016
The anti-Castro Internet advocacy group Foundation for Human Rights in Cuba
has released a post suggesting that the choice of Huawei for the home-access pilot in Old Havana was motivated by Huawei's expertise in censorship and surveillance.
This Old Havana pilot deployment is quite limited, but
Huawei is also the equipment vendor for forthcoming DSL home connectivity and Cuba's WiFi hotpots.
While the embargo was in effect, Huawei was a logical choice for Internet infrastructure in Cuba, but today, the embargo is not keeping the Cubans from considering offers from US and other competitors. Huawei's
experience with and openness to censorship and surveillance may indeed offer them a competitive advantage in Cuba.
-----
Update 2/13/2016
I mentioned the assertion by The Foundation for Human Rights that experience with and an openness to surveillance and censorship gave Huawei a competitive advantage against US infrastructure providers to
Doug Madory, but he disagreed, saying:
No not really. There are plenty of companies that offer products that can be used for surveillance and censorship -- see the usage of Blue Coat of Canada in Syria. Huawei is both inexpensive and not western. Those are probably bigger reasons.
At The Economist event (last December) I spoke with the country manager (of a US firm) for Cuba and he said he was in the room for one of the main presentations from Hauwei to ETECSA. He said Hauwei had brought a dozen engineers and had put a lot of work into their proposal for a telecom build-out. Hauwei wanted this deal very much.

Update 10/27/2016
Norges Rodriguez, @norges14, has pointed out that ETECSA began planning for home DSL in 2012. The following is a copy of cover letter of the memo initiating the planning process and you can download the entire memo
here.
Reading it, I am struck by the bureaucracy . Bureaucracy and vested interests may be the biggest obstacles faced by the Cuban Internet. (This reminds me of their wacky
list of occupations that are authorized for self-employment).
-----
Update 1/12/2017
The
home-connectivity trial in Old Havana is underway and a friend tells me the DSL rollout will begin soon in Santa Clara and Granma.
My guess is that it will only be in the provincial capitals and only some neighborhoods. If ETECSA is implementing the plan foreshadowed in this post, they will be upgrading central offices that are in areas with high population density and phone wires that are in good condition.
My friend heard the prices would be:
15 cuc 30 horas, 256 kb/s
30 cuc 30 horas, 512kb/s
45 cuc 30 horas, 1mb/s
The Web site
Cibercuba says the prices will be approximately:
15 cuc 30 horas, 256 kb/s
50 cuc 30 horas, 512kb/s
70 cuc 30 horas, 1mb/s
115 cuc 30 horas, 2mb/s
Both agree that users will be required to recharge at least once per month.
The good news is that more Cubans will be able to have Internet connectivity in their homes, but the bad news is that this is a lot of money for very slow service by today's standards.
Speeds of 256kkps to 2mbps are very slow using modern DSL equipment. That indicates that either backhaul from the central offices to the Internet is very slow and has to be conserved, the wiring between the central office and the customer premises is in very bad condition, or that the distances between the central office and users are great -- or it could be all of those. A darker thought is that they don't want people using the Internet very much.
Regardless, this speed range is even lower than that anticipated in the leaked document described above. If Cuba rolls out slow home DSL, they will be where the US was in the 1990s.
As I have stated many times -- Cuba should not be recapitulating the evolution of Internet connectivity from dial-up, to DSL, to hybrid fiber-cable or fast DSL to fiber to the premises. They should leapfrog to
next-generation technology and, more important,
next-generation policy -- even if it means accepting (dreaded) direct foreign investment.
