WBSn System Description

Alvarion's Wi-Fi Base Stations with 802.11n support (WBSn) is a family of advanced Gigabit outdoor
Wi-Fi base stations operating in the 2.4 and 5 GHz unlicensed bands. The system combines true
two-way Beamforming 802.11n and interference mitigation technologies together with 3x3:3 MIMO
(2x2:2 in the WBSn-2450-SHD), delivering best capacity and coverage. The interference immunity suite
combines the inherent Beamforming ability to suppress interference, the Dynamic Interference Handling
(DIH) algorithm that continuously optimizes receiver's parameters according to noise level, the Automatic
Channel Selection (ACS) algorithm for selection of best operating channel, the Wireless Alvarion Rate
Adaptation (WARA) mechanism for optimal rate selection in environments with high interference, and
the capabilities of the sector antennas and Down Tilted omni Antennas to reject noise out of their
field-of-view.
The carrier grade WBSn base stations are designed for high reliability and manageability, including a
robust IP-68 certified enclosure for harsh environments, security and QoS features, FCAPS management
suite, and simple and easy installation.
WBSn base stations include rich embedded networking capabilities, including Bridging, Routing and a
fully integrated Access Controller, for flexible service planning and reduced costs.
WBSn base stations are currently available in the following configurations:
Single band base stations operating in the 2.4 GHz band:
»
WBSn-2400-O: A base station with 3 omni antennas.
»
WBSn-2400-S: A base station with an integral high gain triple polarization sector antenna.
Dual band base stations operating in both the 2.4 GHz and 5 GHz bands:
»
WBSn-2450-O: A base station with 3 omni antennas serving both bands.
»
WBSn-2450-S: A base station with an integral high gain triple polarization sector antenna serving
both bands.
»
WBSn-2450-OS: A base station with 3 omni antennas serving the 2.4 GHz band and an integral
high gain triple polarization sector antenna serving the 5 GHz band.
»
WBSn-2450-SO: A base station with an integral high gain triple polarization sector antenna
serving the 2.4 GHz band and 3 omni antennas serving the 5 GHz band.
WBSn-2450-SHD: A dual band base station with an integral high gain, dual polarization, narrow
beam sector antenna serving both the 2.4 GHz and 5 GHz radio bands. The WBSN-2450-SHD is
designed for enhanced performance in high density environments such as sport stadiums, music
arenas and exhibition halls.
