How is ATSC 3.0 reception different than ATSC 1.0?

Work continues on refining standard, deployment plans

This month I’m continuing my coverage of the 2016 IEEE Broadcast Symposium, with a focus on presentations about ATSC 3.0 and the transition from ATSC 1.0 to ATSC 3.0.

The amount of spectrum devoted to TV broadcasters is shrinking—from a peak of 486 MHz before 1983 to 294 MHz today.

The looming repack and stations' aging transmitter plants had broadcast engineers taking a fresh look at transmitters and other RF gear at NAB 2016.

After the FCC incentive auction is complete, likely before we transition to ATSC 3.0, many UHF TV stations will have to move to new channels.

During the transition, many stations will be forced to use auxiliary facilities which will impact their coverage

Successful demonstrations continue but more work remains
