4.2.2 Capacity

The WIBS can support up to 32 channel elements, including all overhead channels.

4.3 Electrical Specifications

4.3.1 Transmitter RF Power

The WIBS shall have maximum 10dBm (10mW) at the output port on the main enclosure. The

remote RF units shall have maximum 40dBm (10W). The other RF front-end facilities, such as in-

building repeaters, optical repeaters, and distributed antennas, shall have proper performance and

maximum transmit power according to installation environments.

4.3.2 Primary Power

The primary power source for the WIBS is the conventional commercial power. The nominal voltage

shall be 120/240VAC, 50/60Hz. The power supply units in the WIBS shall convert the commercial

AC power into DC power with nominal voltage of +27VDC. The +27VDC is then converted into lower

voltages such as +5V, +12V, -12V, +3.3V and +7.5V.

4.3.3 Battery Backup (Optional)

The WIBS shall have a battery backup system for AC power failure. The battery shall be monitored

during normal operation, and charged if necessary. The optional backup battery is secured in an

external compartment.
