. In other words, fully dynamic channel assignment is
used. The modulation is p/ 4 DQPSK; average transmit power at the handset is 10 mW
(80-mW peak power) and no greater than 500 mW (4-W peak power) for the cell site. The
PHS frame duration is 5 ms. Its voice coding technique is 32-kbps ADPCM (Ref. 9)
