Wideband Radio Head Safety coaxial cable insulation. No particular measures are to be taken in case of fire because the emitted concentration of hydrogen fluoride is very low. • A lithium battery is permanently mounted on CU units, and in FON and OCM units. Due to the risk of explosion, this battery must only be removed from the board by an Powerwave authorized service technician. • NiCd batteries are mounted on the FON unit. These batteries contain environmental poisonous substances.

Overview Wideband Radio Head Overview Figure 1-2 Powerwave Wideband Radio Head (WRH) Powerwave WRHs work as bi-directional on-frequency amplifiers used to fill out uncovered areas in wireless mobile systems such as base station fringe areas, tunnels, convention centers, airports and business buildings. It receives, amplifies and transmits signals to/from a base transceiver station (BTS) to/from mobile stations (MS) with both directions being served simultaneously.

Wideband Radio Head Overview WRH-V The WRH-V is designed to provide a higher output power level and comes equipped with a MCPA in the downlink path. The MCPA reduces the number of bands to one band per MCPA used in the cabinet and an additional one band if a high cover is used. The MCPA is located in the cabinet and is supplied from the existing PSU. For two bands, a high cover is used.
