Xirrus' XS-3900 Wireless LAN Array

Multiple Models, Radios

The XS-3900 we tested includes 16 integrated APs, but Xirrus also offers scaled-down versions with four or eight radios for smaller buildings or fewer users. Regardless of the size you choose, the XS-3900 draws much of its appeal from the fact that a single device can provide service across every nonoverlapping channel of both the 2.4-GHz and 5-GHz unlicensed radio bands. That translates to an aggregate data rate of more than 800 MB per second. Two Gigabit Ethernet ports provide backhaul to the wired network, and a 10/100 Ethernet port is available for management. We couldn't effectively evaluate overall system performance (we would have needed at least 15 clients), but we were able to evaluate range and get a general sense of performance and management capabilities.
