BreezeACCESS OFDM

Base Station Equipment

Delivering superior flexibility in architecture and network deployment, the BreezeACCESS OFDM Base Station equipment ensures demand-based scalability combined with flexible modularity.

Base Station Shelf
The 19" 4U Base Station chassis (BS-SH-OF) provides 8 interface slots and two slots designated for power supply modules. The Base Station is powered by a -48 VDC power source, with a back-up module ensuring complete fail-safe redundancy. Up to six BS-AU modules can operate simultaneously, with two supplementary slots reserved for future use.

Indoor/Outdoor Access Units
The BreezeACCESS OFDM indoor/outdoor AU-E-BS-OF Access Unit configuration includes an indoor module and outdoor unit.

The AU-NI-BS-OF indoor unit is a network interface module that fits in the base station chassis, containing the processor, modem, Ethernet interface and IF radio module. The AUs connect to the network backbone via a standard IEEE 802.3 Ethernet 10/100-BaseT (RJ 45) interface.

The indoor and outdoor units are connected via a 50-ohm coaxial Intermediate Frequency (IF), relaying 140 MHz IF signals between the units. Data, power, management and control signals are transmitted between the indoor unit and the outdoor unit via this coaxial cable.

The outdoor units feature two antenna configuration options, delivering enhanced network flexibility, as follows:

• AU-A-BS-OF units: Comprise a radio module and integrated flat panel antenna.
• AU-E-BS-OF units: Include a radio module and RF connector for a separate external antenna.

		AU-A-BS-OF Access Unit includes a module to be inserted into the base station chassis as well as an outdoor unit with an integrated antenna
		AU-E-BS-OF Access Unit includes a module to be inserted into the base station chassis as well as an outdoor unit with an external antenna (sold separately).
		BS-PS-OF Power supply unit for the base station chassis. Powered from a -48 VDC power source.
		BS-SH-OF 19" chassis that can contain up to 6 BS-AU modules and 2 power supply modules.
