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

The Digital Decade – A Look Back

With 2019 coming to a close, we're not just saying goodbye to the past 365 days, we're also saying goodbye to an entire decade. As we bid farewell to the 2010s, we're taking this opportunity to look back and reflect on the digital decade as well as consider what the future might have in store for us all. The past ten years were a whirlwind of change, with new advances in technology exploding onto the market at a faster pace than ever before. 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

5G Funny Numbers: 10M Sign on October, Only 5M Phones in November

Ten million Chinese "reserved" 5G phones in the first two weeks of October, a powerful signal of high demand. Huawei thought they could all get phones in October. But the official figures are less than 1M 5G phones in October and ~5M in November. WTF? It could be an ordinary problem of ramping supply of a new product. It could be the official figures on phone sales are lagging reality by several weeks. more

The Upcoming 5G Confusion

Until now, the 5G industry has spread a lot of hype, but it hasn't affected customers. That's all starting to change as the cellular carriers are starting to offer 5G phones. Many customers who spend extra for 5G phones are going to quickly be frustrated and disappointed as they try to participate in the new 5G world. Consider both AT&T and T-Mobile. Both companies are introducing both a low-band and a high-band 5G phone, and customers who want 5G will have to choose... more

Fake Apps Are a Real Problem

In the short ten years that they've been around, mobile apps have grown to become a staple of modern digital life. With more than five million apps currently available for download in the major app stores, and with over 2,000 new apps being uploaded every day, mobile apps are big business. Fifty-eight percent of shoppers consistently browse e-commerce apps and 49% of all website traffic now comes directly from mobile app users. All this browsing directly translates into spending. more
