FCC to Mull Widening Clearwire's Channels for Speed Bump

At its upcoming meeting in June, the Federal Communications Commission said it will weigh the idea of allowing Clearwire to widen the channels it uses for its WiMax network from 5.5MHz to 20MHz. Clearwire runs its WiMax network in the 2.5GHz spectrum band, but is limited by the narrow channel. If the FCC allows for the channel widening, Clearwire could in theory double its mobile broadband speeds. However, telecom gear makers would first have to create equipment that could support it and then Clearwire would have to deploy that equipment before any speed gains could be realized. Clearwire has struggled financially the last six months. The FCC is scheduled to meet June 9.

T-Mobile recently announced that its mid-band 5G network now covers over 200 million people, a threshold that the industry acknowledges as "nationwide" coverage. (Mid-band 5G offers an ideal balance of fast data speeds and broad coverage compared to 5G in other bands.) In an interview with Phone Scoop, T-Mobile executives detailed how they plan to maintain the company's lead in mid-band 5G even as Verizon and AT&T launch mid-band 5G early next year.

Sony Makes Camera Sensor Breakthrough

Dec 20, 2021
Sony has successfully developed a new world-first camera sensor technology that it claims will widen dynamic range and reduce noise. While the company's current sensor chips use a two-layer design, with a pixel layer and a signal processing circuitry layer, the pixel layer contains both photodiodes and transistors side-by-side.

Verizon, AT&T Moving Forward with C-Band 5G Launch This Week Over FAA Objection

Jan 2, 2022
Verizon and AT&T this morning refused a request by federal transportation officials to delay this week's planned launch of 5G service in the critical new C Band. [Update: By evening, the two companies agreed to a two-week delay.] The FAA (Federal Aviation Administration) insists that the service could potentially interfere with radio altimeters that planes use to measure distance to the ground in poor weather.

Verizon Details C-Band 5G Launch Plans, Promises 10x Data Speed

Jan 4, 2022
Verizon has formally announced plans to launch 5G in the new "C-band" mid-band radio frequencies later his month, and filled in details of what the launch will include. The company is promising to cover 100 million people — nearly 1/3 of the population — with the new network at launch.

AT&T, Dish Big Winners in FCC's Latest Mid-Band Auction

Jan 14, 2022
The US FCC (Federal Communications Commission) just announced the winners of its auction 110, for prime new mid-band radio spectrum ideal for 5G. AT&T and Dish spent the most, each splurging for enough licenses to cover the entire continental US.

error correction: Clear currently uses 10 MHz WiMAX TDD channels

Something is amiss in this Phonescoop news item and in the Fierce Wireless article to which it links.

Yes, BRS/EBS 2500-2600 MHz channelization is variably 5.5 MHz or 6 MHz bandwidth. See the band plan:

http://wireless.fcc.gov/services/brsebs/data/BRS-EBS ... »

But, as Clear controls nearly all of the spectrum in this band, it does not have to respect the boundaries among electromagnetically adjacent channels.

For example, Clear currently deploys mobile WiMAX using the 10 MHz TDD (time division duplex) profile. Each WiMAX 10 MHz channel spans portions of two or three adjacent BRS/EBS 5.5 MHz or 6 MHz channels.
