FCC announces revised 700 MHz rules

Posted in 700 MHz, TV Bands at 2:23 pm by JamesNeel

Basically, the joint commercial/public safety initiative is going forward.Relevant excerpts from the news release:

Under the new band plan, 62 megahertz of spectrum, divided into five spectrumblocks, will be auctioned for commercial uses.

The commercial spectrum will be made available at auction in a mix of geographic area sizes, including Cellular Market Areas (CMAs), Economic Areas (EAs), and Regional Economic Area Groupings (REAGs).

Within the 24 megahertz of public safety spectrum, the public safety wideband spectrum is being redesignated for broadband use to allow for nationwide interoperable broadband communications by public safety users.

There will be a single, nationwide license for the public safety broadband spectrum, assigned to a Public Safety Broadband Licensee, which will work with the adjacent commercial D Block licensee as part of the 700 MHz Public Safety/Private Partnership

The Upper D Block commercial licensee and the Public Safety Broadband Licensee will form a Public Safety/Private Partnership to develop a shared, nationwide interoperable network for both commercial and public safety users.

The licensees of the Upper 700 MHz Band C Block of spectrum will be required to provide a platform that is more open to devices and applications. This would allow consumers to use the handset of their choice and download and use the applications of their choice in this spectrum block, subject to certain reasonable network management conditions that allow the licensee to protect the network from harm.

FCC Report on TV Band Prototype Measurements Released

Posted in TV Bands at 1:58 pm by JamesNeel

Correct sensing at -114 dBm was shown. This may or may not be sufficient depending on the configuration.

Read the report (pdf) here.

*Update* Wow. Here’s a heck of a pull-quote:

Where a DTV signal was strong enough to be received on the TV, [Microsoft's] scanner reported its channel to be free or available 40% to 75% of the time with an average of 58.2% of the time. These percentages are particularly high for Sites 3 and 4.
