1 About AP822

The AP822 is a cost-effective, dual-radio, 802.11a/b/g/n/ac WLAN access point with a 2x2:2ss design. It can operate in the 2.4 GHz band for 802.11n support and in the 5 GHz band for

802.11ac to deliver an aggregate data rate of 1.2 Gbps for demanding business applications such as video and voice. The access point is offered with a choice of internal or external antenna models. Learn more.

AP822 is available in two models AP822iV2 and AP822eV2.

Features

TABLE 1: AP822 Feature List

AP822iV2 AP822eV2

Two dual-band-selectable radios, in either

2.4 GHz or 5.x GHz, capable of operating in IEEE 802.11b/g/a/n and IEEE 802.11ac DRAFT standards, with INTERNAL nas.

Supported by System Director versions 6.1 and greater. Supports 80-MHz channel-bonding (VHT80) in 5.x GHz band with IEEE Std 802.1 1ac. 80-

MHz channel-bonding (VHT80) combines four 20-MHz channels into a single 80-MHz channels for increasing bandwidth.

Supports Plug and Play deployment. Supports multi-layered security including Enterprise WPA2 features such as automatic

traffic inspection. Powered by either a standard IEEE 802.3af or IEEE 802.3at PoE switches or PoE injec-

tors. Supports an optional 12v external power adapter. Supports channel span architecture that requires no channel planning or configuration. Supports wired stations via the secondary Ethernet interface. Provides pre-pack PHY data rate up to 866 Mbps per radio at IEEE Std 802.11ac with

Two dual-band-selectable radios, in either

2.4 GHz or 5.x GHz, capable of operating in IEEE 802.11b/g/a/n and IEEE 802.11ac DRAFT standards, with optional EXTER- NAL antennas.

IEEE Std 802.11ac in AP822

The AP822 series is the first of Meru access point family capable of operating in the IEEE Std

802.11ac mode, which is capable for theoretical throughput rates up to 866 Mbps per radio. IEEE Std 802.11ac is applied only on the 5 GHz band, and its higher throughput level s require

the use of 80 MHz wide channels. 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 S t d 802.11b/g/n clients and radio 2 is configured 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.

Features12

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 wireless 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 - access 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 Commission, 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.

Safety Precautions

IMPORTANT—Read and follow the regulatory instru ctions in Appendix B befo re inst alling and operating this product.
