600mhz RF band going away?

Ok, but reading some of the above, it looks like the 600 MHz band is also already in use, even on LTE networks that can eventually be switched over to 5G...


"In early January, 2019, T-Mobile, Intel, and Ericsson successfully completed the world's first 5G video call and data call on the 600 MHz spectrum. During the tests, it was confirmed that from just one tower, the 5G signal could reach more than a thousand square miles."


"As of February 2019, T-Mobile has built out 600 MHz service in over 2,000 cities covering 42 states. The service currently works with LTE devices only, but the towers can be switched over to 5G when 5G devices are available. The company also has 21,000 small cells deployed and plans to erect 20,000 more going into 2020."


Also from this site: https://venturebeat.com/2019/02/07/t-mobile-has-5g-towers-in-most-top-u-s-markets-handsets-arriving-in-2019/

"Because of recent buildouts, 2,700 cities and towns across 42 states already have 600MHz service for LTE handsets, with the ability to switch those towers over to 5G when the handsets are available."


Now that Samsung phone is available.

The 600 MHz band is active in many markets. I'm speaking specifically for NYC where it is currently not in use. Also note in some places the hardware may be deployed yet still not active.


From the same article you quoted:

"Moreover, T-Mobile’s initial 5G service is somewhat unexpectedly using the same high-speed, short-distance millimeter wave technology as its key rivals. Rather than waiting until the end of 2019 for handsets that support 5G over long-distance 600MHz spectrum, T-Mobile is starting with the Samsung Galaxy S10 5G."

From the FCC:


"...The amount of TV band spectrum available for wireless microphone has decreased as a result of the incentive auction, which was completed on April 13, 2017.  Specifically, most (but not all) of the spectrum on TV channels 38-51 (614-698 MHz), has been repurposed for use by wireless services and will not continue to be available for wireless microphone use.  Wireless microphones that operate in the 600 MHz service band (the 617-652 MHz and 663-698 MHz frequencies) will be required to cease operation sort by no later than July 13, 2020, and may be required to cease operation sooner if they could cause interference to new wireless licensees that commence operations on their licensed spectrum in the 600 MHz service band.  See FCC 15-140.  Spectrum will continue to be available for wireless microphone use on TV channels 2-36 (TV band frequencies that fall below 608 MHz), on portions of the 600 MHz guard band (the 614-616 MHz frequencies) and the 600 MHz duplex gap (the 653-663 MHz frequencies), and in various other spectrum bands outside of the TV bands.  See FCC 15-100, FCC 15-99 

Bands outside the TV bands for wireless microphone use.  In 2015, the Commission provided for new opportunities for licensed wireless microphone operations in spectrum outside of the TV broadcast band, including in the 169-172 MHz band and portions of the 900 MHz band, the 1435-1525 MHz, and the 6875-7125 MHz bands.  Unlicensed wireless microphone operations are permitted in several bands outside of the TV bands, including the 902-928 MHz band, the 1920-1930 MHz band, and portions of the 2.4 GHz and 5 GHz bands. See FCC 15-100..."
