5.3 Architecture
5.3.1 BW Measurements
Frequency Bands PCS Uplink: 1850-1910 MHz Downlink: 1930-1990 MHz
Cell Uplink: 824-849 MHz Downlink: 869-894 MHz
Sub-Bands Full (or partial) A, D, B, E, F & C bands
BW of 5, 7.5, 10, 15 or 20-MHz
Formats Supported SP141 supports dual band PCS & Cellular GSM
SP142 supports dual band PCS & Cellular CDMA
Coverage Area
Fully adaptive, supports multiple simultaneous users. Up to 25,000 ft

)
Max. System Gain Automatic, fully adaptive. Uplink: 82 dB, Downlink: 92 dB
Downlink Operating
Range
-106 to -44 dBm (receive isotropic power).
Coverage reduced at levels below -92 dBm.
Overload Protection Uplink: Fully adaptive
Downlink: Fully adaptive
Max. Input Level
(receive isotropic
power)
Uplink: -5 dBm
Downlink: -44 dBm
Max. Output RF Lev-
els (radiated)
Uplink: +30 dBm EIRP maximum (composite)
Downlink: +7 dBm max (composite). Rated downlink output per carrier is 0dBm
for a maximum of five carriers. If number of carriers exceeds five, per carrier
power is reduced such that the composite downlink power never exceeds
+7dBm EIRP for a nominal antenna gain of 0dBi.
For n carriers, the power per carrier is reduced by 10log n, for the stated com-
posite power.
Third Order Intercept
(radiated)
Uplink: +50 dBm EIRP
Downlink: +30 dBm EIRP
RF Port Impedance DU RF port impedance = 75ohm
CU RF port impedance = 50ohm
CU Coverage Extension RF port impedance = 75ohm
Power Supply Universal power adapter (6 ft AC cable and 20 ft DC cable)
AC Input: (120-240V)
DC Output: +7.5 VDC and +10.25 VDC that connects to the indoor unit. Outdoor
unit power is supplied via the RF cable.
Power Consumption < 50 W
PCS UL BW measured at 20dB down for 20MHz = 22.3MHz
PCS DL BW measured at 20dB down for 20MHz = 22.7MHz
Cellular Band A DL BW measured 20dB down = 23.5MHz
Cellular Band B DL BW measured at 20dB down = 14.3MHz
