Group of Engineers Have Created a Way to Detect Dangerous Objects in Baggage Using Public Wifi

Report describes a technique with which public wifi can be used to identify in-baggage dangerous objects in public spaces that don't typically have affordable screening options. more

Emerging Markets Tech Watch 2012

2011 has been a significant year for the technology sector globally. Information technology is touching more people in more ways than ever before. Developed markets will be considering a 2012 in which business innovation, competitiveness, and service differentiation are built on ubiquitous broadband, cloud computing, smarter mobile computing, and an increasing plethora of Internet-connected devices. By contrast, securing the technology future for developing markets demands that attention be placed on more fundamental issues. more

Goo Goo Goggles: 700MHz Spectrum Auction and the U.S. Taxpayers

Scott Cleland claims the open access rules on 700MHz spectrum triggered by Google's bid fleeced the US taxpayer by $7bn. I don't buy it, even as a signed-up fully-paid network neutrality opponent. Firstly, the numbers ignore economics. If the C block was encumbered, that would raise the prices of the A and B blocks. So you need to take a much smaller differential as to the cost of the encumbrance. more

An Attack on WiFi Spectrum

A little over a year ago, the FCC approved the use of 1,200 MHz of spectrum in the 6 GHz band for public use -- for new WiFi. WiFi is already the most successful deployment of spectrum ever. A year ago, Cisco predicted that by 2022 that WiFi will be carrying more than 50% of global IP traffic. These are amazing statistics when you consider that WiFi has been limited to using 70 MHz of spectrum in the 2.4 GHz spectrum band and 500 MHz in the 5 GHz spectrum band. more

Can SpaceX Launch 30,000 Second-Generation Starlink Satellites? Maybe

The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured... more

To 5.5G and Beyond

I recently saw an article in FierceWireless that reports that Huawei thinks we are going to need an intermediate step between 5G and 6G, something like 5.5G. To me, this raises the more immediate question about why we are not talking about the steps between 4G and 5G? The wireless industry used to tell the truth about cellular technology. You don't need to take my word for it... 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

Global 5G Connections Expected to Reach 1.9 Billion by End of 2023 and 5.9 Billion by End of 2027

The fifth generation of wireless cellular networks, "5G", has seen remarkable growth in the last year, reports industry trade organization 5G Americas. more

Chinese Space Situational Awareness and Traffic Management Regulations and Procedures

In a recent issue of the Dongfang Hour Newsletter, Blaine Curcio pointed out that China's powerful State Administration of Science, Technology, and Industry for National Defence (SASTIND) had published a notice intended to promote the orderly development of microsatellites and strengthen safety management. The notice defines microsatellites as being below 1,000 kilograms, which would include those making up China's planned GwoWang/SatNet broadband constellation. more

The Unprecedented Role of the Internet in the War in Ukraine

The impact of the Internet in the Russia-Ukraine war is unprecedented in speed and scope. The most visible example of this has been President Zelenskyy's use of social media and teleconferencing in his roles as Commander in Chief of the armed forces, a global diplomat, and a leader of the Ukrainian people. 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

Video Recording Now Available of FCC Dec 6th Workshop on PSTN Transition

If you missed attending or listening to the live stream of the US Federal Communication Commission's (FCC) workshop on the transition of the Public Switched Telephone Network (PSTN) to new technologies that was held last week on December 6th, the FCC has very nicely made a video recording available from their website for viewing... FCC Chairman Julius Genachowski also appeared briefly to provide a few comments. more

The FCC Stumbles Into Internet Filtering

What could be bad about free wireless Internet access? How about censorship by federally mandated filters that make it no longer "Internet." That's the effect of the FCC's proposed service rules for Advanced Wireless Service spectrum in the 2155-2180 MHz band, as set out in a July 20 Notice of Proposed Rulemaking. Acting on a request of M2Z Networks, which wants to provide "free, family-friendly wireless broadband," the FCC proposes to require licensees of this spectrum band to offer free two-way wireless broadband Internet service to the public, with least 25% of their network capacity. So far so good, but on the next page, the agency guts the meaning of "broadband Internet" with a content filtering requirement. more

The Other Vote on November 4th

The vote that Federal Communications Commissioners are planning for November 4 is not as important as the voting we'll do on that day, but it does matter a lot to the future of the United States. Unless the forces opposed to progress manage to postpone FCC action (which they are trying very hard to do), the FCC could decide to set the stage for another generation of innovative products with which the US will strengthen its competitive position in global markets... more

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. more
