An Update on LEO Satellites

A lot of rural America continues to hope that low orbit satellite (LEO) service will provide a broadband alternative. It's been a while since I've covered the status of the companies proposing to deploy constellations of satellites for providing broadband. In March, OneWeb filed for Chapter 11 restructuring when it was clear that the company could not raise enough cash to continue the research and development of the satellite product. more

Researchers Demonstrate Serious Privacy Attacks on 4G and 5G Protocols

A group of academic researchers have revealed a design weakness in the 4G/5G protocol which can be exploited by an attacker to identify the victim's presence in a particular cell area just from the victim's soft-identity such as phone number and Twitter handle. more

From Subscribers to Connections

The global telecoms industry numbers remain impressive: By 2020 there will be 6 billion mobile subscribers -- of which, according to Nokia, 95% will have access to wireless broadband by 2015, and by 2020, there will also be 3 billion fixed broadband subscribers. However the relevance of these numbers will decline. By 2020 there will be 50 billion fixed and mobile connections. more

Washington’s 5G Mania Endpoint – Global CyberBalkanisation

Over the past two years, governments and foreign intelligence agencies around the world have tried to understand the inexplicable, chaotic, irrational, indeed maniacal 5G policies of the Trump Administration. Revelations by former Trump administration officials and most recently Trump's niece confirm that there is no rational basis for Trumpian positions and policies and that the best response is to recognize that Washington is no longer capable of playing a meaningful role... more

Economics and Common Sense Deprecates the Common Argument for Lower Spectrum Prices

Outside of China, very few governments would expect a saving in spectrum costs would mostly go to investment. Corporations have other priorities, including advertising and executive salaries. Stockholders come above everything at most companies. Rarely would even 1/3rd of the saving go to capital spending. The U.S. under Trump had a massive tax cut, worth literally billions to Verizon and AT&T. Verizon actually cut investment. AT&T's increase in capex was far lower than the tax saving. more

Obama Administration Announces $400 Million Advanced Wireless Research Initiative

Obama Administration announced today a $400 million Advanced Wireless Research Initiative led by the National Science Foundation (NSF). 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

We Need Public 5G Spectrum

Last October the FCC issued a Notice for Proposed Rulemaking that proposed expanding WiFi into the 6 GHz band of spectrum (5.925 to 7.125 GHz). WiFi has been a huge economic boon to the country, and the FCC recognizes that providing more free public spectrum is a vital piece of the spectrum puzzle. Entrepreneurs have found a myriad of inventive ways to use WiFi that go far beyond what carriers have provided with licensed spectrum. more

Broadband in China

For years I've been hearing how we are losing the broadband battle with China, so I decided to take a look at the current state of broadband in the country. The China Internet Network Information Center (CNNIC) publishes statistics about the state of broadband in the country, and I used the Statistical Report on Internet Development in China from August 2019 in writing this blog. more

The Real White Spaces Debate: To Create or Abolish a Market in the Airwaves

I've been following the "white spaces" for as long as it has been happening -- four, maybe five years -- and I must admit that I am surprised by FCC Chairman Kevin Martin's sudden fondness for them. Until the last days of his chairmanship, Martin never cared for this somewhat radical notion: allowing techies and community activists to spew electromagnetic frequencies in zones currently occupied (at least ostensibly) by the broadcasters. more

Mobile Market Will Also Be Transformed

The success of smart phone, in particular the iPhone, is both a blessing and a curse for the mobile operators. On the one hand it has broken into the monopolistic business models used by most operators and has most certainly loosened part of their stranglehold; on the other, these phones have increased usage on their networks. But these cracks are going to continue and will eventually lead to similar structural changes in the mobile industry to the ones we are currently experiencing in the fixed market. more

5G a Fizzle With Consumers

The cellular companies have made an unprecedented push to get customers interested in 5G. Back in November, I recorded a college football game that enabled me to go back and count the twelve 5G commercials during the game. Advertising during sports events is relatively expensive, so these ads were not purchased at bargain-basement prices. The amount of money being spent on advertising 5G must be gigantic. more

Google Bard Fails to Answer Satellite Internet Questions

In an earlier post, I asked whether electronically steered antennas (ESAs) would replace parabolic antennas in satellite ground stations. I did some research and concluded that it is likely that they will. Next, I discussed the same question with ChatGPT and, while it made several false statements, it made a relevant point that I had overlooked. The relevant addition was positive, but the errors were troublesome, so I decided to try ChatGPT's competitor Google Bard. more

OneWeb Rises From the Ashes – Maybe

A consortium of the UK Government and Bharti Enterprises bought bankrupt OneWeb, a company that had raised $3.2 billion and had acquired valuable spectrum rights, for $1 billion. That is a good start, but a BBC article says experts believe that at least $3 billion is needed to complete the OneWeb constellation. Will they make it?
The UK government will be a source of further funding. OneWeb's primary goal is closing the digital divide by bringing broadband connectivity... more
