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

An In-Depth Interview of OneWeb CEO Greg Wyler

OneWeb is building a large constellation of low-Earth orbit (LEO) Internet-service satellites and Via Satellite has published the "definitive 2018" interview of OneWeb CEO Greg Wyler. The following are some of the quotes that caught my eye... They are going through the final stages of testing now before the launches begin. The satellites have actually performed better than expected in many ways, especially with their Radio Frequency (RF) performance which is really positive. more

SpaceX Wins FCC Approval to Deploy 7,518 Satellites for Broadband Communications

Space Exploration Technologies Corp. is granted permission from U.S. regulators to deploy over 7,000 satellites. more

Obstacles in OneWeb’s Negotiations with Russia

This case illustrates the fact that political, security, and financial negotiations may be as difficult as designing satellites and rockets for a would-be global Internet service provider. OneWeb is investing billions of dollars in a constellation of low-Earth orbit (LEO) Internet-service satellites. In 2015 they placed launch orders for 21 Russian-made Soyuz rockets. more

Security Experts, Privacy Advocates Hopeful Rollout of 5G Can Eliminate Surveillance Vulnerabilities

Security experts and privacy advocates see the rollout of the new 5G wireless network as a possible solution to eliminate surveillance vulnerabilities that allow spying on nearby phone calls. more

Microsoft Cancels Plans to Move Its Internal Wireless Network to IPv6-Only

Microsoft has digressed from a previously announced plan to move its internal wireless guest network to IPv6-only. more

Might CubeSats Provide Broadband Internet Connectivity One Day?

In November, 2016, SpaceX filed a request for approval to launch 4,425 Internet-service satellites using the Ku and Ka frequency bands. The satellites were expected to measure 4 x 1.8 x 1.2 meters. In February, 2018 SpaceX launched two Internet-service test satellites - TinTin A and B - that measured only 1.1 x .7 x .7 meters. Why the size difference? more

Group of Engineers Have Created a Way to Detect Dangerous Objects in Baggage Using Public Wifi

Google’s Loon Announces First Commercial Deal With Telkom Kenya to Provide Internet-by-Balloon

Google's sister-company Loon has announced its first commercial agreement with Telkom Kenya in order to deliver connectivity to the region using a network of giant balloons. more

Cuba on Advances in the “Computerization of Society”

A recent televised roundtable enumerated advances in the computerization of Cuban society, including: Telephone density is 58% with 6.5 million accounts, 5.2 million of which are cell phones. 1.5 million people access Nauta mail with cell phones. Over 1.7 million have permanent accounts. There are 1,713 public-access spots: 709 WiFi locations, over 700 at ETECSA premises and the same number in third-party locations (but 709+1400 is 2109, not 1,713). more

China: We Lead 3GPP Wireless Standards

In 2018, nothing can get approved in 3GPP that China strongly opposes. In the past, 3GPP often was a battle between a few American giants and their European peers. A Qualcomm or a Nokia will still be heard, but the power has shifted. I haven't seen evidence that the Chinese influence has made for better or worse standards. There are now over a billion 4G subscribers at the big 3 Chinese telcos, by far the largest equipment buyers. Nokia, Ericsson, and the other vendors do not dare oppose their largest customers. more

Telesat Begins Testing Low-Earth Orbit Satellite Internet Service

SpaceX and OneWeb get a lot of publicity and have ambitious plans, but Telesat is the first low-Earth orbit (LEO) satellite Internet service provider to begin testing with potential resellers. Last January, Telesat launched a demonstration satellite and it is now ready for testing. Maritime connectivity provider OmniAccess and Australian ISP Optus had committed to testing the system previously and this week they were joined by in-flight entertainment company Global Eagle Entertainment. more

T-Mobile, Sprint Announce Merger Plans, Deal Will Combine 3rd and 4th Largest US Telecom Companies

T-Mobile and Sprint on Sunday announced a plan to merge in a deal that would reduce the number of wireless carriers in the U.S. from four to three. more

Cuba Reaches Five Million Mobile Accounts

Cubans now have 5 million mobile accounts. The five-millionth account was recently opened Guanabacoa, in the eastern part of Havana and we see here that growth slowed last year, but has resumed -- perhaps due to increased 3G availability. Most Cubans have 2G phones, which are used primarily for making calls and sending text messages that may have attached images. more

The 500M Wireless-Only Connections

Around 500M Africans, Indonesians, and Indians are regular Internet users without a landline. Brazil, Indonesia, and Mexico add about 200M more. In total, something like 1B people were wireless-only at the end of Q3 2017. I'm comparing the number of Facebook users (over 250M in India) with the number of landlines (less than 20M in India) for a rough guess at how many are wireless only. In the developed world, 70-90% of all homes have a landline connection... more
