The system also enables a mobile user to communicate with other mobiles. This Wireless Base Station Unit(WBSU) is the distributed radio component of a 1.9 GHz PCS System that is being developed for the operation in the licensed PCS holder. The WBSU is being developed as a subsystem component. The WBSU provides the IS-136A air interface to handheld mobiles operating as a private in-building or campus system. The WBSU is connected to the centralized system controller through a dedicated line interface. This interface utilizes a RJ45 physical connector(modular). This cable connection from the controller to the WBSU provides the following signals. (1) -48Vdc power to supply a WBSU. (2) The clock source of 128kHz for the WBSU to control the frequency accuracy. (3) ISDN BRI(Basic Rate Interface) signal to control the communications. The voltage of -48Vdc generated at the controller gets lower as it comes to the WBSU by its consumption current through the line cable. It can operate at the input line voltage of -48Vdc to -24Vdc. An internal power supply circuit in th WBSU converts the DC input voltage into the internal working voltage of 5V and 3.6V. The WBSU is approximately 12" x 12" x 3". The unit weighs approximately 4kg. A security screw is provided which requires a special tool for removal. The antennas (TX1 and TX2) are integrated to the WBSU and are contained within the assembly. The operating frequency range of the WBSU is the standard licensed bands within the PCS spectrum. The output level of the transceiver is from -10dBW to -38 dBW and is software controlled. The network connections to provide voice or data communications through to the PSTN(Public Switched Telephone Network) or PBX are provided by the central controller and are not part of the WBSU. The TDMA system is the medium for linking calls between PBX and non-public system users and mobile users. The system also enables a mobile user to communicate with other mobiles. The WBSU is wall mounted on exposed interior walls. The basic office environment is air conditioned, normally 25 C(77 F). The humidity is usually low. The WBSU is designed to operate at least in 0°° (32 F) to 40 C(104 F). In an office environment, the equipment is in view but placed in locations that°°° are out of the general traffic areas.

Page 52 of 52 Maximum Permissible Exposure(MPE) : The limit for Maximum Permissible Exposure(MPE) at frequency of 1.96 GHz is 1.00 mW/cm . (1.00 2 mW/cm for General Population/Uncontrolled environment in ß1.1310.) Since the total power of all 2 channels is less than 2000 WERP(3280 WEIRP), compliance testing with the MPE limits of ß1.1307 is not required. The conversion from power to power density uses the following equation : PD = PrG/4 r = EIRP/4 rππ 22 Where : PD is Power Density(in W/m ); 2 Pr is radiated power (in W); G is the numeric gain of the antenna; and EIRP is Equivalent Isotropically Radiated Power(=PrG) = 0.600 (W); and r is the distance(in m) from the antenna The conversion from W/m to mW/cm is:mW/cm = W/m /10 2222 Calculations: At a distance of r = 1 m from the antenna, the power density is (note that this power density will only be induced on an individual if that individual was physically 1 m in line-of-site of the antenna): Power density calculations for MPE ItemsTransmitter Antenna Measured Maximum EIRP(W)0.6 Power Density(W/m )0.048 2 Power Density(mW/cm )0.0048 2 Minimum distance in m for MPE0.07 At this power level, an individual would need to be within 0.07 m of the device in order to be at the limit for General Population/Uncontrolled exposure. This TUT ,at 1m away from the transmitter antenna, is well within the limits for maximum permissible exposure.
