Meru Access Point Features

Chapter 1

About Meru Access Points

The Meru Access Point radio devices communicate with the Meru Controller and form the Wireless LAN (WLAN). The Meru Controller and Access Points connect to the site’s wired LAN through wired switches. Wireless clients associate with the Access Points as they roam throughout the WLAN. As such, the Meru WLAN is an extension of the wired LAN, providing the wireless benefits of client mobility, enhanced access, and dynamic network configuration.

Meru AP

Meru Access Point Features

All Meru Access Points provide the following features:

z Five times more voice calls per Access Point

Meru Access Points use Over-The-Air QoS to provide fine-grained quality of service on a perapplication, per-user, and per-flow basis providing a robust platform for enterprise-quality voice, plus streaming media and data applications. It provides both uplink and downlink QoS between the client and the access point, which is then integrated into the wired QoS mechanisms to provide

About Meru Access Points 1

Meru Access Point Models

end-to-end QoS. Meru Access points deliver a 5-fold increase in voice carrying capacity from the current 5-8 calls per access point to over 30 calls per Meru Access Point with no change to the

802.11 client.

z Over five times the scalability of alternate Access Points

Meru Access Points are unique in their ability to dramatically increase performance over alternate APs, even as client density increases. Meru Access Points, can serve over 100 standard 802.11 active data and voice clients per access point, whereas today's systems are limited to about 10-15 data-only clients. This scalability allows corporations to plan for a wireless usage growth without forklift upgrades to the WLAN infrastructure.

z Zero-loss handoff means applications are not interrupted

Multiple Access Points can be aggregated into a Virtual AP, creating a single wireless network with a wide coverage area that can encompass the entire enterprise campus and provide unparalleled performance and manageability. This breakthrough technology works with any standard 802.11 client device and enables application and security policy persistence while roaming, without requiring the user to re-login or re-authenticate throughout the network coverage area.

z Embedded RF monitor for enhanced security

Traditional approaches to wireless security involve separate devices to monitor the air or legacy APs, or access points that periodically become air monitors. Meru Access Points provide continuous RF monitoring, as well as capture information about all devices that the AP can hear, including clients associated with the access point. Meru WLAN Radar—a third generation rogue AP detection software, provides rogue detection and suppression continuously and without any interruption to the VPN sessions and time-sensitive voice applications that operate on the converged wireless LAN in an enterprise. This constant monitoring enables enhanced security with rogue device detection and prevention that is less disruptive and more cost effective than traditional approaches.

Meru Access Point Models

The Meru Radio Access Point is available in two model families: the Access Point 200 and the Access Point 100.

The Meru Dual Radio Access Point 200 family (AP200) provides models that conform to the specifications provided by the IEEE 802.11a and 802.11g protocols and also provide backward compatibility for the 802.11b protocol. The AP200 works with most standard WiFi clients. The Access Point houses two radio devices: one supplying 802.11a, b, g, or bg service and the other serving as an RF monitor to the Meru controller, providing real-time status of RF activity to optimize the wireless network.

The AP200 is housed in a metal case with a plastic removable cover. As such, it can be used for plenum installations when the plastic cover is removed.

FCC Safety Compliance Statement

The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. When used with approved Meru access point antennas, Meru AP100 products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper installation of this radio according to the instructions found in this manual will result in user exposure that is substantially below the FCC recommended limits.

General Safety Guidelines

z Do not touch or move antenna(s) while the unit is transmitting or receiving.

z Do not hold any component containing a radio so that the antenna is very close to or touching any

exposed parts of the body, especially the face or eyes, while transmitting.

z The use of wireless devices in hazardous locations is limited to the constraints posed by the local

codes, the national codes, and the safety directors of such environments.

Installing the Access Point

Selecting a Location

The AP requires a location that meets the following:

z Relatively unobstructed access to the stations the AP serves

z Power over Ethernet (PoE) connection to the network switch servicing the controller

APs obtain their power from 802.3af standard Power over Ethernet (PoE). The power can be supplied by a PoE-compatible network switch or PoE power injector installed between the switch and the AP. The Power LED on the AP100 (LED furthest from the RJ-45 connector) displays green if power is supplied correctly to the AP.

Select a location with minimal physical obstructions between the AP and the wireless stations. In an office with cubicles, mounting the APs on the ceiling or the wall near the ceiling provides the least obstructed communications path.

Most installations receive the best coverage using the following guidelines:

Installing the Access Point

z For high throughput, place APs approximately 60 feet apart in a grid pattern.

z For adequate coverage, place AP100s approximately 200 feet apart.

z Install APs toward the center of the building.

z Do not install APs near metal objects, such as heating ducts, metal doors, or electric service

panels.

z Relative to the ground, orient the antenna up or down, not sideways.

Note:

Place access points accordingly.

The previous guidelines are general guidelines. Each site has its own unique environment.

Attaching the AP Antennas

Attach the antennas to the connectors on the AP100 (see Figure 5). Rotate the knurled ring at the base of the antenna clockwise to attach the antenna, as shown in the following figure. The ring should be finger-tight.

Safety Precautions

Follow the guidelines in this section to ensure proper operation and safe use of the access point.

FCC Safety Compliance Statement

The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. When used with approved Meru access point antennas, Meru AP200 products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper installation of this radio according to the instructions found in this manual will result in user exposure that is substantially below the FCC recommended limits.

General Safety Guidelines

z Do not touch or move antenna(s) while the unit is transmitting or receiving.

z Do not hold any component containing a radio so that the antenna is very close to or touching any

exposed parts of the body, especially the face or eyes, while transmitting.

z The use of wireless devices in hazardous locations is limited to the constraints posed by the local

codes, the national codes, and the safety directors of such environments.

Unpacking the AP200

The AP200 ships with a mounting bracket and mounting hardware for standard wall mounting. Optional mounting kits are available for mounting the AP200 above or below a hanging ceiling. The AP200 mounting studs are placed so they can be used with brackets supplied by other vendors or to replace an AP100.

Unpacking the AP200

Note:

The AP200 has a security cable slot so you can secure the AP200 with a standard security

cable, such as those used to secure laptop computers.

An array of holes on the mounting bracket (see Figure 12) allow it to be mounted on the wall and over junction boxes or molly bolts. There are also holes for passing the PoE Ethernet or external power supply cable through the bracket if the bracket is mounted on a junction box or over the ceiling T-bar box hanger.

Confirm that the AP200 shipping package contains the following items:

z Access point

z Mounting bracket with two mounting screws

Selecting a Location

The AP200 requires a location that meets the following:

z Relatively unobstructed access to the stations the AP serves

z Power over Ethernet (PoE) connection to the network switch servicing the controller or optional

nearby power supply for external power supply connector

APs can obtain their power from 802.3af standard Power over Ethernet (PoE) or external power supply. For PoE, the power can be supplied by a PoE-compatible network switch or PoE power injector installed between the switch and the AP200. For an external power supply connection, ensure the power source is near to where the AP200 will be mounted.

z Screwdriver

z Wrench or pliers

z Screwdriver

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.

Most installations receive the best coverage using the following guidelines:

Install APs toward the center of the building.

z Do not install APs near metal objects, such as heating ducts, metal doors, or electric service

panels.

z Relative to the ground, orient the antenna up or down, not sideways.

Note:

Place access points accordingly.

The previous guidelines are general guidelines. Each site has its own unique environment.

Attaching the AP200 Antennas

If the AP200 does not have external antennas, attach the antennas to the connectors on the AP200 (see

Figure 13). Rotate the knurled ring at the base of the antenna clockwise to attach the antenna. The

ring should be finger-tight.
