Wireless Array

Introduction 13

All radios are activated with coverage spanning 360 degrees. If within

range, clients will always receive coverage regardless of their geographic

position relative to the Array. Radios may be assigned to 2.4 GHz and/or

5.0 GHz bands in any desired pattern.

Partial pattern coverage

If desired, the Wireless Array can be deployed close to an exterior wall. In

this case, half of all available radios have been deactivated to prevent

redundant signals from “bleeding” beyond the site’s perimeter wall. This

configuration may also be used in those cases where you want to restrict

wireless coverage to selected areas of the building’s interior.

Power over Gigabit Ethernet (PoGE)

Some smaller Arrays and APs (XR-500/600 and XR-2005 Series) are compatible

with IEEE802.3af and/or IEEE802.3at PoE+, and may be connected to appropriate

powered switches. For example, the Xirrus XT-5024 and XT-5048 are 24-and 48-

port 802.3at POE+ managed switches. See the Quick Installation Guide for the

Array/AP for compatible injectors or powered switches.

The Xirrus-supplied XP1, XP2, and XP8 Power over Gigabit Ethernet modules

provide power to Arrays over the same Cat 5e or Cat 6 cable used for data.

Managed modules provide the ability to control power using XMS.
