Xirrus Inc.'s XS-3900 Wireless LAN Array puts many radios and a wireless switch into a single compact 18.65-inch package. The result lets administrators deploy high-density indoor wireless networks while significantly cutting wireless installation and rollout costs. The XS-3900 is packed with bells and whistles. There are 16 integrated access points, specialized multisector antennas, and a single multichannel media access control, all of which lets companies use a single device for wireless LAN in the 5 GHz or IEEE 802.11a and 2.4 GHz or 802.11 b/g spectrums. The advantage here is being able to avoid interference from overlapping channels as well as using the built-in radio option for administrator monitoring. The XS-3900 was tested with 15 laptops, each running Cisco Systems Inc.'s Linksys WPC55AG Dual-Band Wireless A+G Notebook Adapters, and the setup readily handled full performance while all channels simultaneously transmitted. The management and wireless switches need a bit of tweaking; performance topped out at 20 Mbps to 21 Mbps for each 802.11a and 802.11g radio. Also, the array's controller had some difficulty balancing wireless traffic from saturated channels to underused ones. Xirrus representatives promised improved load balancing is on its way. Traffic management remains this unit's strength.
