Whats so good about MotoTRBO DMR TDMA?
Time-Division Multiple-Access (TDMA) preserves the 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, are the better choice for most large organization/enterprise radio users. This means that two seperate conversations can be handled by the one repeater, on the same frequency but a different "channel".
TDMA technology for narrowband 12.5 KHz (6.25 equivalent-6.25e) organization/business radio users, provides advantages of feature flexibility, lower equipment costs, longer battery life, future-readiness, and the proven ability to increase spectral efficiency without risking increased congestion or interference.
