What Is the Business Case for 5G?

There is much hype around 5G, but none of it is new. We saw the same propaganda -- fueled by the manufacturers -- in the run-up to the launch of the 3G and 4G versions of the mobile technology. Driverless cars and a range of other IoT applications can indeed potentially open new revenue streams. The reality, however, is that these markets might not eventuate until somewhere between 2025 and 2030.

Amazon’s Orbiting Infrastructure

I have been following satellite Internet service since the 1990s, but I was surprised when I learned last week that Amazon had filed an application for a 3,236-satellite constellation of low-earth orbit Internet service satellites - Project Kuiper. I shouldn't have been surprised - Amazon was an infrastructure company from the start. In his first post-IPO letter to shareholders in 1997, Jeff Bezos pointed out that their distribution center capacity grew from 50,000 to 285,000 square feet and said their goal remained...

Are Inter-Satellite Laser Links a Bug or a Feature of ISP Constellations?

I hope each of these companies has someone in charge of thinking about what might go wrong with a single, satellite-based network providing fast, low-cost links anywhere on the global Internet. OneWeb, SpaceX, Telesat and Leosat all aspire to be global Internet service providers using constellations of low-Earth orbit (LEO) satellites. Their success will require still-unproven technological innovation, but there are also political stumbling blocks.

SpaceX’s Starlink Internet Service Will Target End Users on Day One

Starting with Teledesic in 1990, would-be Low-Earth Orbit (LEO) satellite constellations have been justified to the FCC, other regulators, and the public as a means of closing the digital divide. Teledesic's goal was "providing affordable access to advanced network connections to all those parts of the world that will never get such advanced capabilities through existing technologies." Today's low-Earth Orbit (LEO) satellite companies make the same claim, but Telesat, OneWeb and Leosat seem to be targeting commercial markets first.

4G Mobile Trials Have Begun in Cuba - What Is Their 3/4/5G Strategy?

During the first month of 3G mobile service, Cuban Internet use increased substantially. At the end of January, ETECSA had 5.4 million mobile users, 35% of which use the Internet and they are adding 5,000 new data customers per day. According to Eliecer Samada, head of ETECSA's wireless access group, the company is now at 160% of the expected capacity.

Five Inconvenient Facts about the Migration to 5G Wireless

An unprecedented disinformation campaign purposefully distorts what consumers and governments understand about the upcoming fifth generation of wireless broadband technology. A variety of company executives and their sponsored advocates want us to believe that the United States already has lost the race to 5G global market supremacy and that it can regain it only with the assistance of a compliant government and a gullible public.

Google Baloons and Telesat Satellites

Telesat will use Google's network operating system. Telesat is making progress. Within the last month, they announced a launch contract with Blue Origin, a successful antenna test with Ball Aerospace and completion of system requirements reviews, but perhaps more interesting is an agreement to use the software defined network (SDN) platform Google has developed for their Project Loon.

Banning 5G Equipment is a Foolish Strategy

It has become popular today around Washington and the venues of its coerced allies to issue threats to ban telecommunications equipment from certain countries - especially equipment intended for 5G use. The guise is vague assertions of "national security." It is an old tactic dating back to the turn of the last century and recurrent for decades. A combination of treaty instruments and collaborative industry standards activity several decades ago largely put an end to the banning tactic - significantly benefitting the entire world.

Electronically Steerable, Flat-Panel Antennas for Satellite and Terrestrial Connectivity

What will the cost and capability of these antennas be in ten or twenty years? What would be the applications and implications of ubiquitous wireless networks? You might have some short-term guesses, like smart cities, but farther out it's science fiction -- Gaia, the Noosphere, 1984? ... Three companies, OneWeb, SpaceX and Telesat, plan to provide global, low-latency broadband Internet service using constellations of low-Earth orbit (LEO) satellites.

The First Month of Cuban 3G Mobile Internet Service

ETECSA, Cuba's government monopoly ISP, is offering a number of stopgap Internet services -- navigation rooms, home DSL and WiFi hotspots, but the recently rolled out 3G mobile service is the most important. The plot to the right shows the normalized rate of Cuban domain name requests to Oracle servers during the first full month of operation - a surrogate estimate of Internet traffic volume.
