The FCC has long battled for a more efficient deployment of unused spectrum, endeavouring to adapt rules governing 'white space' TV spectrum (largely gifted to broadcasters years ago, and generally in the 700MHz band) to newly released spectrum (in the 600MHz band). This will considerably improve wireless broadband coverage where it is needed most... Certainly, in the US's disjointed broadband sector there are considerable challenges ahead... more
A recent Infonetics press release says "WiMAX has gained such momentum across so many regions that it is no longer sensible to suggest that WiMAX growth will be flattened by the emergence of LTE [Long Term Evolution] in the next few years." Probably true, but it's also clear WiMAX will never reach the scale of either mainstream wireless family, i.e., WiFi or GSM/3GSM. By comparison with these giants, WiMAX will be a fringe operation. The critical issue is volume, and what counts is the wireless technology brand, not the technology itself. more
The Federal Communications Commission (FCC) has proposed a ban on some wireless microphones and other low-powered devices that operate in the 700-MHz band after the digital TV transition in February, next year. This is part of an attempt to clear any potential interference with the "white spaces" spectrum which will be fully available for "public safety as well as commercial wireless services". more
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
The internet is unavailable and/or unaffordable by about 50% of the world's population. The situation is worse in, but not confined to, developing nations where the service is typically sub-standard when it is available.Geostationary satellite connectivity is available globally, but it is slow and expensive because the satellites are high above the Earth. Low-Earth orbit (LEO) satellites can deliver speeds comparable to terrestrial links, but constellations of many satellites would be needed to serve the entire planet. more
The Federal Communications Commission on Thursday sent a letter to an individual in Brooklyn, New York, alleging that a device in the individual's residence used to mine Bitcoin is generating spurious radiofrequency emissions, causing interference to a portion of T-Mobile's mobile telephone and broadband network. more
Who would dare to predict the year the Internet will reach 50 billion addressable devices? Thomas Noren, head of LTE product development at Ericsson sees one day 50 billion devices shouldered by LTE. He sees LTE as the truly global standard putting to rest the long and acrimonious rivalry between CDMA and GSM protagonists and even sees the Chinese third way with their TD-SCDMA aligned on LTE. Mobile WiMax is, in his mind, already relegated to the dustbin of history... more
SpaceX launched its eighth Starlink mission via the Falcon 9 rocket on Wednesday, carrying 60 more satellites for its Internet satellite constellation, bringing the total in operation on orbit to 480. more
The mainly politically-driven debate - FttH versus wireless broadband - is spreading uninformed messages and half-truths in the market. And confusing messages from mobile operators are also blurring the picture. All well-informed people confirm that this is a nonsensical debate -- both infrastructures will coexist with, and supplement, each other. more
In a move to be celebrated by many of us with a VoIP background, the United States Federal Communications Commission (FCC) announced today the appointment of Henning Schulzrinne as Chief Technology Officer (CTO). As the release indicates, Henning's role as CTO will be to: ...guide the FCC's work on technology and engineering issues, together with the FCC's Office of Engineering and Technology. more
It has been a long time coming. In the world of global 5G security, there is only one principal forum. The somewhat cryptically named 3GPP SA3 is dedicated to 5G security and holding its 103rd meeting electronically next week from 17 to 28 May with 772 submitted documents and 189 participants registered. SA3 meets every 60 days and exists at the security center of an ecosystem of numerous technical groups encompassing many hundreds of companies, industry organizations, and government agencies worldwide. more
The new Clearwire could be game-changing, but the rules of the game may not be quite as Clearwire presents them. I have been wondering since last July whether something significant would happen in the Google/Sprint world. The deal announcement earlier this weekseems to be that key development... In a nutshell, Sprint will contribute its substantial spectrum licenses in the 2.5 GHz range and its WiMAX-related assets and intellectual property. Google, Intel, Comcast, Time Warner Cable, and Bright House Networks will invest a total of $3.2 billion. more
Despite several groundbreaking technical achievements over the past nine years, Google's parent company Alphabet has decided to end the Loon project. The company said the road to commercial viability has proven much longer and riskier than hoped. more
I posted reviews of important LEO-satellite Internet service developments during 2017 and 2018. I've been updating those posts during the years and have 16 new posts for 2019. In 2019 we saw four inciteful simulations, Leosat suspending operations and Amazon announcing the availability of a new ground station service and plans for a LEO constellation, progress in phased-array antennas but a lowering of expectations for inter-satellite laser links (ISLLs), new competition from China... more
There was a recent dispute between OneWeb and SpaceX regarding the possibility of a collision between two of their low-Earth orbit (LEO) satellites. OneWeb's satellite (OneWeb-1078) was launched on March 25 and headed for its orbit at an altitude of 1,200 km when, in early April, it passed near a SpaceX satellite (Starlink-1546) in orbit at about 450 km. There was no collision, but subsequently, OneWeb's government affairs chief Chris McLaughlin said... more
