Is 5G Radiation Safe?

There is a lot of public sentiment against placing small cell sites on residential streets. There is a particular fear of broadcasting higher millimeter wave frequencies near to homes since these frequencies have never been in widespread use before. In the public's mind, higher frequencies mean a greater danger of health problems related to exposure to radiofrequency emissions. more

Wireless Carriers Clashing with FCC Over Proposed Regulations on Mobile Advertising

US Federal Communications Commission is proposing privacy rules that wireless companies claim could hurt their ability to compete with the likes of Facebook and Google. more

A Winning Biden 5G Strategy: Flatten the Curve

No, not the COVID curve - the curve of U.S. engagement in global industry 5G activities. Let me explain. What is known as 5G actually consists of a broad array of fundamentally revolutionary virtualization platforms that are constantly, collectively developed by industry in several dozen open global bodies. These bodies meet every few weeks, and several score companies around the world process scores to hundreds of input documents to produce many hundreds of effectively mandatory... more

Satellite and Space Debris Tracking as a Service

On February 2, 1989, the Soviet Union launched its Cosmos 2004 satellite and the Chinese launched a rocket on December 15, 2009. Cosmos 2004 is now defunct, as is the third stage of that Chinese rocket, but both remain in orbit. They were long forgotten until recently when LeoLabs, a satellite tracking service, predicted that they had a good chance of colliding at 971 km over the sea near Antarctica. more

Google, the NAB, and a Third Way in ‘White Spaces’ Debate

Google co-founder Larry Page came to Washington last week to take on the National Association of Broadcasters (NAB), the lobbying group that represents over-the-air television stations. It's a whole new adversary for the beleaguered broadcasters, who have been fighting cable and satellite television for years. The Federal Communications Commission is currently considering a proposal, by Google and other tech players. It would allow tech companies to build electronic devices that transmit wireless internet signals over the "white spaces," or the vacant holes in the broadcast television band. "We have an ambitious goal called pervasive connectivity through ubiquitous broadband networks," said Page... more

UK: Barely One in Ten Users Are Satisfied With Mobile Broadband

A web-based poll on the Mobile Broadband Genie site had participants 1160 who were asked: "Is your mobile broadband fast enough?" 133 yes; 740 no; 287 don't know. Perceptions of the term "mobile broadband" appear to far exceed what is being delivered. While operators have been competing to offer cross-subsidized laptop and netbook deals with higher usage caps and ever cheaper mobile Internet deals, they seem to have overlooked the quality of the service. more

FCC Ends Inquires Into “Zero Rating” Programs

"AT&T and Verizon just got a free pass from the FCC to divide up the internet," Colin Lecher reporting in The Verge. more

Cuba’s New WiFi Regulations – Good, Bad or Meh?

Soon after ETECSA began rolling out WiFi hotspots for Internet access, people began linking to them from homes and community street nets. These connections and importing the WiFi equipment they used were illegal, but generally tolerated as long as they remained apolitical and avoided pornography. Regulations passed last month legalized some of this activity in a bid to boost connectivity by allowing Internet access from homes and small private businesses like restaurants and vacation rentals that are located close enough to a hotspot to establish a WiFi connection. more

SpaceX Applies for a Constellation Re-Design and Announces Beta Test Dates

This week SpaceX petitioned the FCC to reconfigure their Starlink constellation and Elon Musk outlined their beta testing plan. As shown below, the most significant configuration change is reducing the altitude of four of the five groups of orbital planes by around 50%. The total number of satellites and the number orbiting at a 53-degree inclination, which gives good coverage over relatively affluent regions, are not changed very much. more

Geely’s LEO Constellation for Mobile Vehicle Connectivity

The Geely Holding Group (GHG) is a private Chinese conglomerate that is highly diversified but best known as an auto manufacturer that envisions itself as a "global mobile technology group." GHG announced this week that it has begun construction of an intelligent satellite production and testing facility that will include modular satellite manufacturing, satellite testing, satellite R&D, and cloud computing centers.

Update Mar 2, 2024:

Geely launched eleven satellites in the same 50-degree inclination plane as the first nine, but there was a considerable delay between the two launches. The first nine were launched in June 2022 and the second 11 were launched in February 2024. The delay may have been caused by a satellite re-design -- The mass of these satellites is 130 kg whereas the first nine satellites had masses of 100 kg.

The launch cadence will have to speed up if they are to reach their goal of beginning service with 72 t satellites next year. more

Hassle Over LEOs

Every second, 4.5 billion people using computers and other electronic devices send 100,000 gigabytes of information to each other. Around 60% of the world's population has an Internet connection. North America and Europe have penetrations of 95% and 87%. But Asia and Africa do not yet get beyond 54% and 40%. On those continents, there are many remote areas where there is no Internet yet. At least no affordable Internet. more

Can 5G Compete with Cable Broadband?

One of the recurring themes used to promote 5G is that wireless broadband is going to become a serious competitor to wireline broadband. There are two primary types of broadband competition - competition by price or performance. Cable companies have largely won the broadband battle in cities and suburbs, and I've been thinking about the competition that cable companies might see from 5G. 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

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... more

Starlink Broadband Service – More on the Beta Plus Exciting Video

If you have last-generation satellite internet access, broadband from a wireless ISP (WISP), or even satellite television from DISH or DIRECTV, an installer came and carefully aimed a dish antenna for you. Starlink, a broadband access service from Elon Musk's SpaceX company, reimagines the install process and, in most cases, eliminates the need for an installer. The Starlink dish can sit on the ground or the peak of your roof; more importantly, it aims itself, as you see in the accompanying video. more
