DMR Key Features

Time-Division Multiple-Access (TDMA) preserves full channel width and divides it into alternating time slots that can each carry an individual call.
Motorola maintains that two-slot 12.5 kHz TDMA-based systems (providing 6.25 kHz equivalency) is more efficient.
This means that two separate conversations can be handled by the one repeater, on the same frequency but on a different "channel".
TDMA technology for narrowband 12.5 KHz (6.25 equivalent-6.25e) provides advantages of:
  1. feature flexibility
  2. lower equipment costs
  3. longer battery life
  4. future-readiness
  5. spectrum efficiency
