The Myth of 5G and Driverless Cars

A colleague sent me an article that had been published earlier this year in MachineDesign magazine that predicts that driverless cars can't be realized until we have a ubiquitous 5G network. When looking for the original article on the web I noticed numerous similar articles like this one in Forbes that have the same opinion. These articles and other similar articles predict that high-bandwidth, low-latency 5G networks are only a few years away. more

Happy Birthday Wi-Fi

This year is the twentieth anniversary of the formation of the Wi-Fi Alliance and the launch of commercial Wi-Fi. Wi-Fi has become so ubiquitous in our lives that it's hard to believe that it's only been twenty years since all broadband connections came with wires. In 1999 most people were still using dial-up, and that's the year when early adapters started buying DSL. I remember having incredibly long phone cords so that I could use my laptop at different places around the house. more

Ren to Donald Trump: Take Our 5G, Please

Ren Zhengfei tells the Economist and the NY Times he is prepared to give the US essentially everything the President has asked, including the crown jewels: the complete design and source code of Huawei's 5G system. Ren would "license the entire Huawei 5G platform to any American company that wants to manufacture it and install it and operate it, completely independent of Huawei." more

Unlicensed Millimeter Wave Spectrum

I haven't seen it talked about a lot, but the FCC has set aside millimeter wave spectrum that can be used by anybody to provide broadband. That means that entities will be able to use the spectrum in rural America in areas that the big cellphone companies are likely to ignore. The FCC set aside the V band (60 GHz) as unlicensed spectrum. This band provides 14 GHz of contiguous spectrum available for anybody to use. This is an interesting spectrum because it has a few drawbacks. more

Inter-Satellite Laser Link Update

Inter-satellite laser links (ISLLs) and electronically steerable flat panel antennas are critical technologies for constellations of low-Earth orbit (LEO) Internet-service satellites. Low-cost antennas are critical for the mass consumer market, and ISLLs are required for an effective Internet backbone in space. In an earlier post, we saw that progress is being made on antennas; this one looks at ISLLs. more

5G Real Security Threats Lost in Trump's Twitter Diplomacy

A new report on 5G and geopolitics by Oxford Information Labs details the complex landscape of 5G security. Importantly, it draws out how a variety of proven technical concerns around the quality of Huawei security practices and equipment are drowned out by the US' Twitter diplomacy. Critical international dialogue on genuine cybersecurity concerns relating to 5G and Huawei are being lost in the noise of the US-China trade war. more

Huawei's Very Red World

The map below shows countries working with Huawei 5G in red and pink. As can be seen, Huawei is doing very well in 5G, although it's not as dominant as the colors here suggest. Ericsson is actually close to Huawei in 5G revenue, aided by the ban in the US and Australia. Years ago, Huawei was the price leader in order to break into the European market. more

A New Cellular Carrier?

One of the most interesting aspects of the proposed merger of Sprint and T-Mobile is that the agreement now includes selling some of Sprint's spectrum to Dish Networks to enable them to become a 5G cellular provider. This arrangement is part of the compromise required by the Department of Justice to preserve industry competition when the major wireless carriers shrink from four to three. more

Questions Raised by the Takeover of SNET, Havana’s Community Network

Last May, Cuba's Ministry of Communication (MINCOM) announced resolutions 98 and 99 limiting wireles stransmission power and outdoor cables that made community networks like Havana's SNET, illegal. Since SNET was the world's largest community network that did not have Internet access, implementation of the resolutions was postponed for 60 days for negotiations between SNET administrators and MINCOM. more

Almost All 5G Estimates for 2019-2020 Need to Be Doubled

The remarkable take rate in Korea and China is invalidating almost all projections of 5G subscriptions. The 5G promotion has consumers wanting to buy, buy, buy. Huawei Mate 20 5G is selling for only US$30 more than the 4G model. At that price, who would want to buy a 4G phone that could be obsolete in a year or two? In the first two weeks of sale, over a million Chinese bought Huawei's 5G phone. more
