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

A Transport Protocol’s Perspective on Optimizing Starlink Performance

Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. more

Planning for the Ugly End of the Phone Network

Consumers who have a choice are quickly deciding they don't need the old copper-based phone network, often known as POTS for Plain Old Telephone Service. We use our cellphones for talking even when we're not mobile. The cell phones have built in phone directories, easy ways to return calls, the ability to call a number on a web page; and we don't share them with our parents or children... It's a good year for traditional phone companies when they don't lose more than 10% of their POTS lines. more

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

Starlink Promising Satellite Cellular Service: A Possible Game-Changer for Remote Areas and Outdoor Enthusiasts

Starlink recently launched a new webpage that advertises the future ability to deliver text, voice, and data to 4G cell phones via satellite. The texting service is supposed to be available in 2024, with voice and data coming in 2025. The service will require a user to have a view of the open sky. 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

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

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

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

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

The Battle for IoT

There is an interesting battle going on to be the technology that monetizes the control of Internet of Things devices. Like a lot of tech hype, IoT has developed a lot slower than initially predicted -- but it's now finally becoming a big business. I think back to a decade ago when tech prognosticators said we'd soon be living in a virtual cloud of small monitors that would monitor everything in our life. According to those early predictions, our farm fields should already be fully automated, and we should all be living in the smart home envisioned by the Jetsonsmore

Telesat and the Government of Canada Join Forces to Tackle Canada’s Digital Divide

The Canadian satellite operator, Telesat announced this week that it has partnered with the Government of Canada in a mission to provide affordable high-speed Internet connectivity across rural and remote areas of Canada through the development of Telesat's LEO Satellite Constellation. more

Cable’s Move Into Mobile: Calculated and Deliberate

If you believe Cable Operators are not thinking about Mobile Networks and what kind of synergies could bring them increased cash-flow in the future, then you've probably missed the obvious signs laid out since 2008. ... Starting with their investment in Clearwire in 2008, companies like Comcast, Time Warner Cable and Bright House have upped their anti in wireless and mobile strategies. 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

Computing Clouds in Orbit – A Possible Roadmap

Last week, I predicted that much of the Internet and most cloud datacenters would launch into space in the next ten years. Today the only part of the Internet in space is a very small amount of "bent-pipe" access: signals which go from a user to a satellite and bounce back down to a ground station which feeds them into the terrestrial internet where all processing is done and all queries answered by internet-connected servers, many of them in cloud data centers. more
