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

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

Study Reveals U.S. Carriers Throttle Online Video on Their Mobile Networks Even When Not Congested

A study conducted by researchers at Northeastern University and the University of Massachusetts Amherst involving 650,000 tests indicates U.S. carriers are throttling online video on their mobile networks regardless of whether or not those networks are congested. 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

An Optimistic Update From Telesat

Emily Jackson interviewed Dan Goldberg, Telesat President and CEO, in a recent episode of the Down to Business podcast. The interview followed the announcement that the Canadian Government would contribute $85 million (all amounts are in Canadian dollars) to support research and development in support of Telesat's planned constellation of low-Earth orbit (LEO) satellites and another $600 million to subsidize Internet connectivity in rural Canada. more

Terahertz WiFi

While labs across the world are busy figuring out how to implement the 5G standards, there are scientists already working in the higher frequency spectrum looking to achieve even faster speeds. The frequencies that are just now being explored are labeled as the terahertz range and are at 300 GHz and higher spectrum. This spectrum is the upper ranges of radio spectrum and lies just below ultraviolet light. more

OneWeb Fails in Latest Attempt to Get Russian Approval for Its Worldwide Internet Coverage Plan

Russian State Commission for Radio Frequencies has denied the global satellite communications company OneWeb to use a certain band of radio frequencies in Russia that the company seeks as part of its plan to launch hundreds of satellites into orbit to provide worldwide internet coverage. more

In the 5G Era, at Least 20 Million U.S. Homes Will Rely on Wireless for Broadband

There now can be no doubt that fixed wireless, mostly 5G, will be a viable business in the right locations. Today's wireless has enormous capacity, enough to supply the broadband needs of a significant population. It's better than most DSL and a workable alternative to cable in many locations. Traffic demand is falling, with Cisco predicting the U.S. will fall to 31% growth in 2021. more

Latecomer Amazon Will Be a Formidable Satellite ISP Competitor

In spite of being a latecomer to the race to deploy a constellation of low-Earth orbit (LEO) broadband Internet satellites, Amazon's Project Kuiper will be a formidable competitor. SpaceX, OneWeb and Telesat already have test satellites in orbit, but Amazon has several strategic advantages. For a start, each of the LEO broadband competitors plans to end the digital divide by providing global connectivity to end-users and small organizations in underserved areas... 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

Will Broadband Go Wireless?

For years it's been impossible to go to any industry forum without meeting a few folks who predict that residential broadband will go wireless. This buzz has accelerated with the exaggerated claims that fast 5G broadband is right around the corner. I've seen even more talk about this due to a recent Pew poll that shows that the number of people that only use their cellphones for data has climbed significantly over the last few years – I'm going to discuss that poll in another upcoming blog. more

Why 5G Won’t Be Here Tomorrow

I just saw another article yesterday written by a major-city newspaper telling the public that 5G is coming in 2020. I hate to see reporters who have accepted the nonsense being peddled by the carriers without digging a little deeper to find the truth. At some point in the near future, the public will finally realize that the 5G talk has mostly been hype. more

Amazon’s AWS Ground Station Service Is Now Available

Amazon announced that they would be providing satellite ground station service last year and Andy Jassy, CEO of Amazon Web services, announced its availability in the video at the end of this post. AWS Ground Station is a fully managed, ready-to-go ground station service... This sounds like a compelling case, especially for a small operator or startup, but I don't know how the prices compare to existing services or building proprietary ground stations. more

Havana Can Have 5G Before Miami

Compared to Miami, Havana is an Internet desert, but Havana may have 5G wireless connectivity before Miami. 5G architecture, US politics and policy, and the 5G timetable favor Havana. Let's start with 5G architecture. 5G will require many "small cells" because it uses high-frequency radio signals that don't travel as far as 4G signals and are more easily blocked by obstructions like trees and buildings. more
