Wi-Fi Array
14 Introduction
Extended Coverage
One XN16 solution enables you to replace up to sixteen access points (includes
one omnidirectional IAP for monitoring the network). Fifteen IAP radios with
integrated directional antennas provide increased wireless range and enhanced
data rates in all directions. With a Wi-Fi Array deployed, far fewer access points
are needed and wired-like resiliency is delivered throughout your wireless
network. Your Wi-Fi Array deployment ensures:
z Continuous connectivity if an IAP (radio) fails.
z Continuous connectivity if an Array fails.
z Continuous connectivity if a WDS link or switch fails.
z Continuous connectivity if a Gigabit uplink or switch fails.
Flexible Coverage Schemes
Your Wi-Fi Array offers flexible coverage schemes for each wireless technology.
