FCC Proposes Over $200 Million in Fines Against Four Largest Wireless Carriers

The U.S. Federal Communications Commission has proposed fines against the country's four largest wireless carriers for apparently selling access to their customers' location information without taking reasonable measures to protect against unauthorized access to that information. more

5G Reality Check: February 2020

Given all the clueless, nonsensical assertions coming out of Washington these days about 5G and purported leadership, it seemed time to do another reality check. It was timely at the moment because, with the Coronavirus concerns, the massive 3GPP 5G industry collaboration engine switched to virtual meeting mode for February. Thus – with travel barriers to participation completely absent – the participation metrics represent a real litmus test for even nominal engagement in global 5G industry collaboration and technology development. more

Cracks Appearing in Trump’s Huawei Boycott

It must have been a galling experience for President Trump when his good mate British Prime Minister Boris Johnson failed to step in line with Trump's demand that the UK should also boycott the Chinese firm Huawei by not allowing them to be involved in the rollout of 5G in Britain. However, the involvement of Huawei will be limited. It further proves that boycotting Huawei is a political and not a technical issue. more

A Reality Check on 5G in Rural America

FCC Chairman Ajit Pai recently told the crowd at CES that 5G would be a huge benefit to rural America and would help to close the rural broadband divide. I have to imagine he's saying this to keep rural legislators on board to support that FCC's emphasis on promoting 5G. I've thought hard about the topic, and I have a hard time seeing how 5G will make much difference in rural America – particularly with broadband. more

China on Its Way to Becoming a Formidable Satellite Internet Service Competitor

In a study of the Internet in China in the late 1990s, my colleagues and I observed that "China has been able to execute plans effectively by allocating resources to competing, government-owned enterprises," and Kai-Fu Lee shows that they have pursued a similar strategy with respect to AI. Now they are doing the same with low-Earth orbit (LEO) broadband satellite constellations. more

FCC Gives Google, Sony and Others Full Authorization for Commercial Deployment of 3.5 GHz Spectrum

The U.S. Federal Communications Commission (FCC) on Monday announced it is allowing full commercial use of 3.5 GHz band for broadband connectivity and 5G. more

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

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

The Role of FttH in the Development of 5G

As the rollout of fiber to the home project (FttH) remains a slow process, it is no wonder that more and more people are looking towards mobile as a potential alternative. Obviously, mobile communication has improved over recent years in providing excellent access to broadband. It has also become more affordable. At the same time, there is the hype surrounding 5G, and the public relations and media machines of the vendors involved makes you believe that this will become a real competitor to the slow-moving FttH developments. more

U.S. Has Poor Cellular Video

Opensignal recently published a report that looks around the world at the quality of cellular video. Video has become a key part of the cellular experience as people are using cellphones for entertainment, and since social media and advertising have migrated to video. The use of cellular video is exploding. Netflix reports that 25% of its total streaming worldwide is sent to mobile devices. The new Disney+ app that was just launched got over 3 million downloads of their cellular app in just the first 24 hours. more

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2019

I posted reviews of important LEO-satellite Internet service developments during 2017 and 2018. I've been updating those posts during the years and have 16 new posts for 2019. In 2019 we saw four inciteful simulations, Leosat suspending operations and Amazon announcing the availability of a new ground station service and plans for a LEO constellation, progress in phased-array antennas but a lowering of expectations for inter-satellite laser links (ISLLs), new competition from China... more

New York City Releases Internet Master Plan For City’s Broadband Future

New York City Mayor Bill de Blasio and Chief Technology Officer John Paul Farmer today announced an Internet Master Plan for the City aimed to chart a path for internet providers in the private sector to work in partnership with the City in order to address market gaps and deliver universal broadband to New Yorkers. more

The Power of Data in Smart City Developments

A few weeks, I attended a one-day conference at the Queensland University of Technology (QUT) at the occasion of the launch of their new $7.5 million Centre for Data Science. This laboratory is also the lead node of a new Australian Data Science Network, bringing together data science organizations from across the country. The new center aims to support data-led decisions across key areas like health, environment, business, government and society -- in short, data for the good. 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

Starlink Simulation Shows Low Latency Without Inter-Satellite Laser Links

Handley's simulation shows that, while not as fast as an equivalent ISLL path, long bent-pipe paths would typically have lower latency than terrestrial fiber routes between the same two points. Mark Handley, a professor at University College London, has made two terrific videos based on runs of his simulation of the first – 1,584 satellite – phase of SpaceX's Starlink Internet-service constellation. I discussed the first video, which assumes that the satellites have inter-satellite laser links (ISLLs), in recent post. more
