2.7.5 Three Sector Six TRX (S222) Configuration
The three sector, six TRX (S222) configuration is available as a 15 Watt, 25 Watt,
40 Watt or a 50 Watt, six antenna configuration. See Table 2-17.
This configuration has three sectors with two TRXs in one sector and one TRX in
the other two sectors. For the 15 Watt, 25 Watt, 40 Watt and 50 Watt S222
configurations, connect your antennas as shown in Figure 2-26.
2.7.6 RF Radiation Hazard
As of October 15, 1997, all products must address the issue of Human Exposure
to RF electromagnetic fields. Referring to OET Bulletin 65, RF radiation limits for
the 300 - 1500 MHz range are f / 300 mW/cm
2
for occupational exposure, and f /
1500 mW/cm
2
for general population exposure (where f is frequency in MHz). At
the 869 MHz cellular band these limits are 2.90 mW/cm
2
for occupational
exposure, and 0.58 mW/cm
2
for general population exposure.
The UltraWAVE base station may consist of up to six separate transceivers, with
each of the transmitters operating at a maximum output power of +47 dBm
