800 MHz Center Frequencies

Table 1-2 lists the selected 800 MHz CDMA candidate operating

channels and the corresponding transmit and receive frequencies for

Regular Band Class 0 (North America). Figure 1-2 shows the CDMA

Frequency Spectrum for Table 1-2. Center frequencies (in MHz) for

channels not shown in the table may be calculated as follows:

For Channels 1 – 799

S For TX

TX = 870 + (0.03 * Channel #)

Example: Channel 262

TX = 870 +0.03 * 262

TX = 877.86 MHz

S For RX

RX = 825 + (0.03 * Channel#)

Example: Channel 262

RX = 825 + (0.03 * 262)

RX = 832.860 MHz

For Channels 991 – 1023

S For TX

TX = 870 + [0.03 *(Channel# – 1023)]

Example: Channel 1015

TX = 870 + [0.03 * (1015 – 1023)]

TX = 870.240 MHz

S For RX

RX = 825 + [0.03 * (Channel# – 1023)]

Example: Channel 262

RX = 825 + [0.03 * (262–1023)]

RX = 847.830 MHz

Conditionally Valid – Valid channels in TIA/EIA–97–D

that are <885 kHz from the operator’s band edge. If the

operator’s system must coexist with another system that

uses an adjacent frequency band, it is recommended that

the operator coordinate with the other operator to

determine if the usage of the Reduced–Sideband Spectral

Mask is required for Conditionally Valid channels. The

Reduced–Sideband Spectral Mask is in addition to other

spectral masks that apply.
