Why 5G Is in Trouble (and How to Fix It)

I have a somewhat unconventional view of 5G. I just happen to believe it is the right one. It is trapped inside a category error about the nature of packet networking, and this means it is in trouble. As context, we are seeing the present broadband Internet access model maturing and begin to reach its peak. 5G eagerly anticipates the next wave of applications. As such, 5G is attempting to both extend and transcend the present "undifferentiated data sludge" model of mobile broadband. more

Will Low-Earth Orbit Satellite Internet Service Providers Succeed?

In 1990, Teledesic was formed to deliver satellite-based Internet service. Cellular pioneer Craig McCaw, Microsoft co-founder Bill Gates and Saudi Prince Alwaleed bin Talal were early investors and Boeing was both an investor and the prime contractor. Teledesic hoped to offer global Internet connectivity using a constellation of 840 satellites in low-Earth orbit (LEO) at an altitude of 700 km... Teledesic failed. Twenty seven years later three companies SpaceX, OneWeb and Boeing are trying to do what Teledesic could not do. Will they succeed? more

The Role of the BFR in SpaceX’s Satellite Internet Service

SpaceX started with their Falcon 1 booster followed by several versions of the Falcon 9. The Falcon Heavy will fly later this year, and the rocket that will take the first person to Mars is called, for now, the Big F*ing Rocket or BFR. The 150-ton BFR payload will be ten times that of the Falcon 9. It will have an extra landing-guidance engine for reliable reusability and SpaceX also expects to be able to soft-land and reuse the second-stage payload rocket as well as its protective nose cone, substantially reducing cost per launch. more

Inevitability of Global Standards for Non-Terrestrial Spectrum Sharing

Three companies, SpaceX, OneWeb and Boeing have announced ambitious plans to put thousands of Internet-service satellites in non-geostationary low-Earth orbit (NGSO) and other companies like ViaSat and SES are currently operating hundreds of communication satellites in medium-Earth and higher, geostationary orbits. With so many satellites orbiting in different planes and at different altitudes, there are bound to be frequent "inline events"... more

FCC Approves Google’s Project Loon Balloons for Puerto Rico and the Virgin Islands

The FCC has granted Alphabet's Project Loon an experimental license to operate in Puerto Rico and the US Virgin Islands for the purpose of helping the islands regain Internet connectivity. more

Bluetooth-Based Attack Vector Dubbed “BlueBorne” Exposes Almost Every Connected Device

Security firm, Armis Labs, has revealed a new attack vector that can target major mobile, desktop, and IoT operating systems, including Android, iOS, Windows, and Linux, and the devices using them.

Can Constellations of Internet Routing Satellites Compete With Long-Distance Terrestrial Cables?

Three companies, SpaceX, OneWeb, and Boeing are working on constellations of low-Earth orbiting satellites to provide Internet connectivity. While all three may be thinking of competing with long, terrestrial cables, SpaceX CEO Elon Musk said "the goal will be to have the majority of long-distance traffic go over this (satellite) network" at the opening of SpaceX's Seattle office in 2015. Can he pull that off? more

Boeing’s Satellite Internet Project

I recently posted updates on the satellite Internet service projects of SpaceX and OneWeb. OneWeb and SpaceX have received a lot of publicity, but there is a third entry in the global satellite Internet race -- Boeing. Boeing has applied for a license to launch a constellation of 2,956 Internet-access satellites orbiting at an altitude of 1,200 km. (In a subsequent amendment, the orbits were lowered to three different levels). They outlined a two phase plan... more

Why Farmers Are Using Wifi to Grow Your Grapes

Recently, California farmer Craig Thompson got a pretty nifty upgrade for his irrigation: a broadband-connected Hydrawise control system that would automatically manage and monitor the irrigation of his olive and grape fields and collect data to alert him if there was a problem. He woke up the next morning to fields he could have assumed were appropriately hydrated, but the Hydrawise system quickly proved its worth when he looked at the data coming out of it. more

OneWeb Satellite Internet Project Status Update

SpaceX and OneWeb are formidable, experienced competitors in a race to become global Internet service providers using satellite constellations -- routers in space. I posted a status report on SpaceX last week, now let's look at OneWeb. OneWeb founder and executive chairman Greg Wyler has extensive experience with networking in developing nations. In 2003 his company, Terracom, signed a contract to connect Rwandan schools, government institutions, and homes. more

SpaceX Satellite Internet Project Status Update

I've been following the efforts of SpaceX and OneWeb to become global Internet service providers using constellations of low-Earth orbit (LEO) satellites for some time. Launch times are getting close, so I'm posting a status update on SpaceX's project... The Senate Committee on Commerce, Science, and Transportation held a hearing titled "Investing in America's Broadband Infrastructure: Exploring Ways to Reduce Barriers to Deployment" on May 3, 2017, and one of the expert witnesses was Patricia Cooper, SpaceX Vice President, Satellite Government Affairs. more

Wireless Innovations for a Networked Society

Last week, I had the honor of moderating an engaging panel discussion at Mozilla on the need for community networks and the important role they can play in bridging the digital divide. The panel highlighted the success stories of some of the existing California-based initiatives that are actively working toward building solutions to get under-served communities online. more

Mozilla, National Science Foundation Offer $2M Prize for a Decentralized Web

Mozilla and the National Science Foundation have announced a $2 million prize for ideas that decentralize the web; prizes will be available for both early-stage design concepts and fully-working prototypes. more

Questions About Cuba’s 3G Mobile Expansion

ETECSA, Cuba's telecom provider and sole operator of fixed telephony, mobile, and data in the country, is rolling out 3G mobile service in Havana and elsewhere in the country. Telegeography reports there are now 229 3G base stations in Cuba... ETECSA says 3G coverage is available in all of Havana, provincial capitals and tourist resorts. AT&T says there is GSM/GPRS coverage for 85% of national territory. more

5G Frequency Fees Are Waived in Singapore to Help Drive Market Tests

Singapore government has waived telecom frequency fees for 5G trials until December 2019 in order to catalyze market growth and discovery of potential use cases. more
