Broadband Satellite Issues

One of the most interesting aspects of serving broadband from low-orbit satellites is that it brings issues related to space into broadband discussion. Space issues were less important for high earth orbit satellites that sit 20,000 miles above the earth. Other than an occasional impact from sunspots, there wasn't much of note. But there are two recent events that highlight our new focus on low-earth orbit satellites. more

Smart Cities Want to Co-Design Change With Telcos

With 5G earmarked as a game-changer for cities, wireless technologies are already widely deployed by leading smart cities, including those here in Australia. However, cities do not want to be locked into proprietary technology solutions, rather seeing themselves as a platform on which many organisations can build infrastructure, applications, and services to benefit all citizens and all local businesses. more

My Telecom Predictions for 2020

There is already a growing shortage of fiber resources that includes engineers, construction companies, and fiber consultants. The upcoming $16.4 billion RDOF program will create a resource shortage in 2020 for those who can help companies seek grant funding. Once the grants are awarded, the size of the program will add stress to the resources needed to build networks. Companies that don't line up their experts early might find themselves without help. more

Killing 3G

I have bad news for anybody still clinging to their flip phones. All of the big cellular carriers have announced plans to end 3G cellular service, and each has a different timeline in mind... The amount of usage on 3G networks is still significant. GSMA reported that at the end of 2018 that as many as 17% of US cellular customers still made 3G connections, which accounted for as much as 19% of all cellular connections. 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

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

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

FCC Gives Approval to LTE-U Devices

Ericsson, Nokia get go-ahead for LTE-U base stations despite early fears they might interfere with Wi-Fi. more

Government Shutdown Halts Trump’s FCC Deregulation Agenda, Says Tom Wheeler

Former FCC Chairman, Tom Wheeler, warns that the effect of U.S. government shutdown on the Trump Federal Communications Commission (FCC) will last a long time even if the shutdown were to end tomorrow. more

Mobile’s Need for Fibre

It was interesting to see that in New Zealand Vodafone had second thoughts and decided to come up with its own proposal of forming a consortium of network operators, rather than simply supporting the government's announcement of its FttH plans. Our analysis of this change of mind is that mobile operators increasingly need fibre networks to sustain the enormous growth in mobile broadband. Most mobile stations around the world are not connected to a fibre network. more

ICANN and GSMA Sign Memorandum of Understanding

ICANN and the mobile network operators trade body, GSM Association (GSMA) today signed a Memorandum of Understanding (MoU) at the Mobile World Congress being held this week in Barcelona. 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

United States: 276M Wireless Users, 740B Text messages Recorded for the First Half of 2009

According to CTIA's semi-annual wireless industry report, text messaging continues to be enormously popular in the United States, with more than 740 billion text messages carried on carriers' networks during the first half of 2009 - that is 4.1 billion messages per day. This number is nearly double from last year which was reported at 385 billion text messages. 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
