Installation Guide 9
2.3 Access Point Placement
For optimal performance, install the Access Point away from transformers, heavy-duty motors, fluorescent lights,
microwave ovens, refrigerators and other industrial equipment. Signal loss can occur when metal, concrete, walls
or floors block transmission. Install the Access Point in an open area or add Access Points as needed to improve
coverage.
Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright enough. An
area lit sharply might
minimize coverage and create dark areas. Uniform antenna placement in an area (like even
placement of a light bulb) provides even, efficient coverage.
Install the Access Point at an ideal height of 10 feet from the ground.
To maximize the Access Point’s radio coverage area, Motorola Solutions recommends conducting a site survey to
define and document radio interference obstacles before installing the Access Point.
2.4 Power Injector System
An AP-7522 Access Point can receive power via an Ethernet cable connected to the GE1/POE (LAN) port.
When users purchase a WLAN solution, they often need to place Access Points in obscure locations. In the past, a
dedicated power source was required for each Access Point in addition to the Ethernet infrastructure. This often
required an electrical contractor to install power drops at each Access Point location. The Power Injector merges
power and Ethernet into one cable, reducing the burden of installation and allowing optimal Access Point
placement in respect to the intended coverage area.
The AP-7522’s supported Power Injector (Part No. AP-PSBIAS-2P3-ATR) is a high power POE Injector delivering up
to 30 watts. The Access Point can only use a Power Injector when connecting the unit to the Access Point’s GE1/POE
port. The Power Injector is separately ordered and not shipped with an existing AP SKU.
CAUTION
Using a non-compliant injector, or an injector supporting legacy modes
will not allow the AP-7522 to function at optimum performance levels.
CAUTION
Do not plug the AP-PSBIAS-2P3-ATR Power Injector into the Access
Point’s Console port. Connecting the Power Injector into the console
port can damage the port and void the AP-7522’s product warranty.
