The Addressing System for the Next (Wireless) Internet

I gave a talk yesterday at Northwestern called A DNS in the Air. My idea is that, in order to scale, the emerging wireless Internet needs something analogous to the domain name system (DNS) -- the infrastructure that allows you to reach sites across the Net. Billions of mobile phones, and even more billions of connected sensors and other wireless devices will completely overwhelm our current spectrum management regime. AT&T Wireless estimates we will need between 250 and 600 TIMES the current wireless capacity in 2018, less than a decade from now. more

SpaceX Starlink in Ukraine – a Week Later

Last week I wrote about the arrival of a truckload of SpaceX Starlink terminals in Ukraine and their potential value to government and resistance leaders. A lot has happened in the ensuing week - this is an update. Last week, using Mike Puchol's Starlink tracking service, I found that users in Kyiv would have 100 percent uptime with connections through as many as nine satellites to ground stations in Turkey, Poland, and Lithuania. more

Verizon and Skype: Who’s the Winner?

Until only recently, has it been remotely plausible to consider such different companies joining forces. I've written about Skype often, and for the most part, they've been a threat for incumbents of all stripes. To hear about this from Verizon during such a public event makes it very clear that the sands are shifting once more, and yet again, VoIP is the culprit. more

The G7 and EU Join China in Call for Space Debris and Collision Regulation

Last month, the Chinese government published space situational awareness and traffic management regulations and procedures designed to guard against collisions in orbit and mitigate space debris, and this month, at the G7 summit, delegates from Canada, France, Germany, Italy, Japan, the USA, the UK, and the EU pledged to take action to tackle the growing hazard of space debris as our planet's orbit becomes increasingly crowded. more

Google Playing to Win in the 700 MHz Auctions

Many say Google will bid to lose in the upcoming 700 MHz auctions and many more are equivocating. The idea is Google's entry alone will induce enough openness, and besides they couldn't afford to become an operator. This shows a total lack of understanding! more

No Virginia, You Have No Duty to Secure Your WiFi Access Point

Every now and again a report flies across the network about the police breaking down someone's door and attempting to arrest the home owner for bad things online - assuming that whatever happened from that person's Internet connection is their fault. Now there are lots of problems with this - lots of problems. But one of the big ones is that anyone can access an open access point... more

From Loon to Taara: Google’s Moonshot Delivering Wireless Backhaul

You may recall a number of years ago when Google experimented with delivering broadband from balloons in an effort labeled Project Loon. The project was eventually dropped, but a remnant of the project has now resurfaced as Taara - broadband delivered terrestrially by lasers. more

EU’s Cyber Security Agency Identifying Five Areas as Critical IT Security

The EU's 'cyber security' Agency ENISA (The European Network and Information Security Agency) has launched a new report concluding that the EU should focus its future IT security research on five areas: cloud computing, real-time detection and diagnosis systems, future wireless networks, sensor networks, and supply chain integrity. more

Will Googlerola Be Able to Fight Data Caps?

"Is Google Turning Into a Mobile Phone Company?" asks the headline in Andrew Ross Sorkin's New York Times story. Wrong question, IMHO. But is Google doing the deal at least partly to give it leverage over wireless providers? I think so. The biggest threat to the growth of Smart Phones and tablets and other Google businesses like YouTube is the imposition of data caps and metered pricing by wireless providers like at&t and Verizon Wireless. more

A Cool Simulation of SpaceX’s Revised Satellite Broadband Plan

On November 15, the FCC approved a revision to the plan for Starlink, SpaceX's forthcoming broadband satellite service. The new plan reduces the number of satellites from 4,525 to 4,409 and lowers the altitude of the phase-1 satellites from 1,100 to 550 km. Mark Handley, a professor at University College London, has created videos based on simulations he ran of both the original and revised phase 1 plans. more

Starlink Has Begun Delivering Promised Latency Cuts

In his January 12 SpaceX update, Elon Musk said the biggest goal for Starlink from a technical standpoint is to get the mean latency below 20 ms. He expanded by saying that given the speed of light, 8 ms is the absolute minimum latency for a satellite at 550 km. He believes they can optimize terrestrial and inter-satellite links, and minimize queueing delays and dropped packets, to recude the the rest of the time to below 10 ms. more

Communications and the London Olympics

Communications will be one of the most critical areas during the London Olympic Games. The industry is working to establish shared access networks -- would it not be nice if they did this everywhere, all the time? They are also working very closely with British Olympic Association, London Transport, the broadcasters and content providers. Mobile coverage will be the biggest shared infrastructure in the world. 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

Might CubeSats Provide Broadband Internet Connectivity One Day?

In November, 2016, SpaceX filed a request for approval to launch 4,425 Internet-service satellites using the Ku and Ka frequency bands. The satellites were expected to measure 4 x 1.8 x 1.2 meters. In February, 2018 SpaceX launched two Internet-service test satellites - TinTin A and B - that measured only 1.1 x .7 x .7 meters. Why the size difference? more

Google and the White Spaces

The white spaces proceeding is the next big opportunity for experiments in alternative ways of providing wireless highspeed internet access... A key advantage of unlicensed spectrum is that experiments in new technology can be carried out without asking the permission of spectrum licensees. To date, we have made very little spectrum available for unlicensed use and experimentation. The FCC has the discretion to decide whether the digital television "white spaces" may be used on an unlicensed basis... more
