PCS Band Channel Plan To calculate the transmitter frequency:

North American Band Channel range: 0 to 1199

Transmitter frequencies:

1930 to 1989.95 MHz

Offset: −80 MHz

Channel spacing: 50 kHz

TX freq = (channel × 0.05) + 1930 MHz

RX freq = (channel × 0.05) +1850 MHz

Korean Band Proposal 0 Channel range: 0 to 1300

Transmitter frequencies:

1805 to 1870 MHz

Offset: −90 MHz

Channel spacing: 50 kHz

TX freq = (channel × 0.05) + 1805 MHz

RX freq = (channel × 0.05) +1715 MHz

Korean Band Proposal 1 Channel range: 1 to 1300

Transmitter frequencies:

1805 to 1870 MHz

Offset: −90 MHz

Channel spacing: 50 kHz

Channels 1 to 600:

TX freq = (channel × 0.05) + 1840 MHz

RX freq = (channel × 0.05) +1750 MHz

Channels 601 to 1300:

TX = ((channel − 600) × 0.05) + 1805 MHz

RX = ((channel − 600) × 0.05) +1715 MHz
