Are Inter-Satellite Laser Links a Bug or a Feature of ISP Constellations?

I hope each of these companies has someone in charge of thinking about what might go wrong with a single, satellite-based network providing fast, low-cost links anywhere on the global Internet. OneWeb, SpaceX, Telesat and Leosat all aspire to be global Internet service providers using constellations of low-Earth orbit (LEO) satellites. Their success will require still-unproven technological innovation, but there are also political stumbling blocks. more

Google and ETECSA Will Agree to Exchange Internet Traffic Without Charge

Google and ETECSA have signed a memorandum of understanding agreeing to negotiate a peering agreement that would allow cost-free data exchange between their networks once an undersea cable physically connects them. Google has worked hard to establish a relationship with ETECSA and the Cuban government. In recent years, Cuba, not the US, has limited the Cuban Internet. This agreement telegraphs a change in Cuban policy. more

SpaceX’s Starlink Internet Service Will Target End Users on Day One

Starting with Teledesic in 1990, would-be Low-Earth Orbit (LEO) satellite constellations have been justified to the FCC, other regulators, and the public as a means of closing the digital divide. Teledesic's goal was "providing affordable access to advanced network connections to all those parts of the world that will never get such advanced capabilities through existing technologies." Today's low-Earth Orbit (LEO) satellite companies make the same claim, but Telesat, OneWeb and Leosat seem to be targeting commercial markets first. more

Facebook Enters Wholesale Fiber Business, Plans to Sell Unused Capacity on New Fiber Routes

Facebooks says it intends to allow third parties - including local and regional providers - to purchase excess capacity on its fiber. more

High-Speed Fibre Makes Up One-Quarter of Fixed Broadband Internet Connections in OECD Countries

Organization for Economic Co-operation and Development (OECD) reports that the share of high-speed fiber in fixed broadband Internet connections in its member countries has risen to 25%, up from 12% eight years ago. more

Google Baloons and Telesat Satellites

Telesat will use Google's network operating system. Telesat is making progress. Within the last month, they announced a launch contract with Blue Origin, a successful antenna test with Ball Aerospace and completion of system requirements reviews, but perhaps more interesting is an agreement to use the software defined network (SDN) platform Google has developed for their Project Loon. more

Simulation of OneWeb, SpaceX and Telesat’s Proposed Global Broadband Constellations

Inigo del Portillo and his colleagues at MIT have run a simulation comparing OneWeb, SpaceX and Telesat's proposed low-Earth orbit Internet service constellations. The models are based on the initial FCC filings by the companies and demand and data-rate estimates by the authors. I will mention subsequent amendments to the filings below later in the post. more

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2018

At the end of 2017, I posted a review of important LEO-satellite Internet service developments. I've been updating those posts during the year and have also added the following new posts in 2018. ... SpaceX, OneWeb and Telesat are planning to offer Internet-service from LEO, but O3b is already providing connectivity to relatively large customers like mobile phone companies, government organizations, and cruise ship lines using a constellation of medium-Earth orbit (MEO) satellites.  more

OneWeb’s Offer to Sell a Share of Their Satellite Internet Service to Russia

OneWeb has a contract to launch Internet-service satellites on Russian-made Soyuz rockets and has a joint venture with Gonets, a Russian satellite operator, as a marketing partner in Russia. However, the Russian government has expressed concerns about security, dragged their feet on spectrum allocation and complained about US sanctions. This led OneWeb to make two concessions. more

Lessons from the O2 Network Outage: The Real Cost of Manual Processes

More than 30 million people lost their data connectivity on December 6, 2018, in the United Kingdom as O2's network suffered from a nationwide service outage. Based on several reports, the incident was caused by a human error at Ericsson, the telecoms supplier responsible for operating certain parts of the O2 network. To compensate for the downtime and tarnished reputation, the O2 management is now reportedly seeking damages of up to a hundred million pounds from Ericsson. more

The Case for Making 3G Mobile Internet Access Free in Cuba

Last week ETECSA began offering 3G mobile access to Cuba's national intranet and the global Internet and President Diaz-Canal tweeted the news. His tweet has received 216 comments so far and reading through them, many are effusively positive... Others were critical, noting that the prices are high relative to Cuban incomes (one said "absurd") and the technology is obsolete -- "Congratulations, but they're 20 years late." more

Cuba Rolls Out 3G Mobile Access

After several months of trials, ETECSA announced the availablity of third-generation mobile access to their national intranet and the global Internet in a televised "round table." The prices are quite steep for a typical Cuban and I suspect there would be relatively few subscribers among the 34% of the population that is not yet covered. Furthermore, many users will have to buy new phones to use the service. (There are still 1,084 second-generation mobile base stations in Cuba). more

Microsoft’s New Study Reports Over 162 Million in US Lack Broadband, FCC Says Only 24.7 Million

A new study by Microsoft researchers suggests the actual use of high-speed internet across the US is quite different than those of from the FCC. more

Rural Home Connectivity in Cuba

Cuba's government monopoly ISP ETECSA in October announced special home connectivity rates for some of the poorest towns in rural Cuba. The monthly charge for 30 hours of 512/256 Kbps DSL access in those towns will be 5 CUC. In other areas where home connectivity is available, the minimum monthly charge is 15 CUC for 30 hours of 1,024/256 kbps service and faster, more expensive, plans are available. more

A Cool Simulation of SpaceX’s Revised Satellite Broadband Plan

On November 15, the FCC approved a revision to the plan for Starlink, SpaceX's forthcoming broadband satellite service. The new plan reduces the number of satellites from 4,525 to 4,409 and lowers the altitude of the phase-1 satellites from 1,100 to 550 km. Mark Handley, a professor at University College London, has created videos based on simulations he ran of both the original and revised phase 1 plans. more
