Chapter 1 Overview
Network Deployment Examples
•
Streetlight power tap adapter (AIR-PWR-ST-LT-R3P=)—connects to the light control connector on
a streetlight pole and provides AC power to the access point.
•
1520 power injector (AIR-PWRINJ1500-2=)—provides PoE to the access point.
•
40-ft (12.2-m) power cord for light pole installations in the US and Canada
(AIR-CORD-R3P-40NA=)—provides AC power to the access point. One end of the power cord is
terminated with an access point AC power connector, and the other end is terminated with an AC
plug.
•
Battery backup module (AIR-1520-BATT-6AH). The integrated battery can be used for temporary
backup power during external power interruptions.

Network Deployment Examples
The access point is a wireless device designed for wireless client access and point-to-point bridging,
point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point
provides 5-GHz backhaul capability to link with another access point to reach a wired network
connection or to provide repeater operations for other access points.
The access point plays one of two primary radio roles: a root access point (hereafter called a RAP) or the
access points that relay their wireless connections to the controller are called mesh access points
(MAPs). When the access point has a wired Ethernet, fiber-optic, or cable connection to the controller
(through a switch), the radio role is called a RAP. A RAP is a parent node to any bridging or mesh
network. A controller can support one or more RAPs, each one parenting the same or different wireless
networks. There can be more than one RAP for the same mesh network for redundancy. Both RAP and
MAP access points can support wireless clients using the 2.4-GHz radio.
Note
The access point must be configured as a RAP in the controller, whereas the MAP role is a default
setting.
When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller,
the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface)
to other MAPs and finally to a RAP with an Ethernet or cable connection through a switch to the
controller. MAPs can also have a wired Ethernet connection to a local LAN and serve as a bridge
endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).
