Meru Networks AP822, Installation Manual

Page: 13 / 66

Installation Location 13
When a radio on AP822 is configured for IEEE Std 802.11ac operation, it is automatically set
to operate on the 5 GHz band. By default, the radio 1 is set to operate on the 2.4 GHz band
(Channel 6, 20 MHz channel width) to support IEEE Std 802.11b/g/n clients and radio 2 is con-
figured for IEEE Std 802.11ac on 5 GHz (Primary Channel 36 with 80 MHz channel width).
With backward compatibility, AP822’s Radio 2 supports either IEEE 802.11a or IEEE 802.11a/
n clients.
Installation Location
All AP822 interconnected equipment must be contained within the same building, including
the interconnected equipment's associated LAN connection. Ceiling mount is recommended
but wall mount is also supported. In addition, the AP822 should be mounted in a location that
meets the following conditions:
•
Unobstructed access to stations - relatively unobstructed access to the stations the AP
serves. Select a location with minimal physical obstructions between the AP and the wire-
less stations. In an office with cubicles, mounting the APs below a hanging ceiling or the
wall near the ceiling provides the least obstructed communications path. On a wall, orient
the AP822 horizontally so that you can read the Meru logo without tilting your head at 90
degrees - this orientation provides optimum MIMO performance.
• Access to power - a ccess to wall outlet or to a Power over Ethernet (PoE) connection to
the network switch servicing the controller.
•
Capacity Planning - AP822 is capable of associating up to 128 clients per radio or 256 cli-
ents per system. For optimum performance, Meru Networks recommend planning up to 50
clients per radio for a mixed WLAN voice, video, and data. Users can, however, achieve
higher client capacity in a data traffic only environment. Refer to the Meru Deployment
Guides on the support site for more information.
•
Install APs toward the center of the building.
• Place APs about 80 feet apart.
•
Do not install APs near metal objects, such as heating ducts, metal doors, or electric ser-
vice panels.
•
If you install an AP822 on a pole, its coverage will be a half spherical shape. Mounting two
AP822’s (back to back) on a poll does not provide full coverage (spherical shape). This
could potentially interfere with each other resulting in poor coverage.
With grant of additional regulatory approvals and Permit-but-Ask by US Federal Communication Com-
mission, users can configure two radios in AP822 on the same band (i.e., both radios are on the 2.4
GHz but in the different or same channels, or both radios are on the 5.x GHz but in the different or
same channels). However, user shall expect performance deterioration due to RF collision. collocation,
or co-channel interference (CCI). It is important that the users reduce AP822 transmit power, for each
radio, by at-least 3 dBm for its default setting. It is also recommended to apply such use case in
AP822eV2 with pigtail attached external antennas only.
