Meru Access Points and Radio Switch

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

Meru Access Point AP200 Series

The Meru Access Point AP200 series provides two models that conform to the specifications provided by the IEEE 802.11a and 802.11g protocols and provide backward compatibility for the 802.11b protocol. An AP200 works with most standard Wi-Fi clients.

z The AP201 houses a single 802.11a/b/g radio device z The AP208 supports a maximum of two radio devices that can simultaneously run

two protocols (802.11b, g or b/g on interface 1 and 802.11a on interface 2).

Alternately the second radio can be configured to run as an RF monitor to the Meru

Controller, providing real-time status of RF activity to optimize the wireless

network.

The Meru Access Point AP200 series (referred hereafter as the AP200, unless specifically referring to the AP201 or AP208) 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.

Radio Switch RS4000

The Radio Switch RS4000 enables high-capacity enterprise-class wireless LAN connectivity with full support of standard 802.11 security and network management features. Each RS4000 contains four 802.11 radios (two 802.11b/g, two 802.11a) for high data and voice throughput – an essential requirement for high user-density environments with several simultaneous users. Classrooms and convention halls are typical deployment applications of the Radio Switch. Deploying the Radio Switch is easy— as with wireless access points, the Radio Switch can be installed wherever wireless coverage is needed. For large buildings with multiple rooms and floors, more than one Radio Switch can be installed to cover the desired area. Wireless users can seamlessly roam from one Radio Switch to another, getting high-capacity WLAN access throughout the wireless enterprise enabled with multiple Radio Switches. The RS4000 also balances radio traffic across its RF channels and resolves contention within each RF channel such that users receive a switched wireless experience with dedicated bandwidth to execute a variety of applications ranging from web browsing and VoIP mobility to multimedia streaming.

Internal Use Only—Beta Draft

The RS4000 ships with either a high-gain omni-directional indoor antenna or a 180degree directional indoor antenna that aggregates and layers radio transmissions from each of the built-in radios. The antenna can broadcast every channel available to blanket the area around the Radio Switch, yet avoid interference and contention. This simplifies deployment efforts by eliminating the need for additional antennas for each radio. More importantly, RF channel planning efforts are greatly simplified.

Using the RS4000, wireless users experience the benefits of switching technology on Wi-Fi—dedicated bandwidth, traffic separation, and multi-service network support.

The RS4000 can be deployed with up to two 802.11b/g and two 802.11a channels active on the radio interfaces. The 802.11b/g channels must be separated by a minimum of 8 channels (for example, channels 1 and 9), so the recommended set is channels 1 and 11, typically. The 802.11a channels must be separated by a minimum of 80MHz/16 channels for best performance (for example, channels 36 and 52).

Install the AP300

Select a Location

All AP300 interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection. In addition, the AP300 should be mounted in a location that meets the following conditions:

z 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 (plenum is supported) or the wall near the ceiling provides the least obstructed communications path. For an external power supply connection, ensure the power source is near to where the AP300 will be mounted.

z Access to wall outlet or a to a Power over Ethernet (PoE) connection to the network switch servicing

the controller.

Most installations receive the best coverage using the following guidelines:

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:

Caution!

When changing the orientation of the antennas, be sure to slightly loosen the knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you might damage the internal cabling in the AP.

Install the Optional Remote Antenna Mount on the Ceiling

Use an optional Remote Antenna Mount for one or both AP300 radios to remotely connect the AP300 antennas. The 3*3 SMA Antenna Stand allows you to relocate either your current antennas or the Meru's High Gain Dipole Antennas to a location with clearer signal paths to the other devices in your wireless network. The Remote Antenna Mount can be placed either below the ceiling tile or on the wall. The default orientation for the Mount is suitable for a ceiling mount, but you can attach the Mount to a wall with some modifications.

Use one mount per radio; for example AP310 needs one unit, and AP320 needs two units.The Antenna Mount uses low-loss Plenum rated LMR195 cable and SMA connectors.

Figure 9: Remote Antenna Mount

The remote antenna mount kit includes:

z Antenna stand with attached cable. The three antenna SMA female connectors on the Antenna

Mount support AP300 antenna diversity. This feature gives the client the ability to automatically choose the antenna receiving the strongest signal.

Radio Position Planning

Never construct a radio mast, pole, or tower near overhead power lines. In addition, local regulations may limit or prevent construction of a high radio mast or tower. If your OAP180 link requires a high radio mast or tower, consult a professional contractor for advice. Once the required antenna height has been determined, other factors affecting the precise position of the OAP180 must be considered.

z Be sure there are no other radio antennas within 2 m (6 ft.) of the OAP180. z Place the OAP180 away from power and telephone lines. z Avoid placing the OAP180 too close to any metallic, reflective surfaces, such as roof-

installed air-conditioning equipment, tinted windows, wire fences, or water pipes.

Radio Interference

Avoiding radio interference is an important part of wireless planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are

Installing the Access Points

any strong radio signals using the 802.11a or 802.11bg channel frequencies. Always use a channel frequency that is furthest away from another signal.

Weather Conditions

Take into account any extreme weather conditions that are known to affect your location. Consider these factors:

z Tem pe r a t u re — The OAP180 is tested for norma l operation in temperatures from - 40°F

to 140°F. Operating in temperatures outside of this range may cause the unit to fail.

z Wind Velocity — The OAP180 can operate in winds up to 44 m/s and survive higher wind

speeds up to 66 m/s. You must consider the known maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force.

z Lightning — The OAP180 includes its own built-in lightning surge protection. However,

you should make sure that the unit, any supporting structure, and cables are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed. Antenna sockets should point upwards in a vertical manner

z Rain — The OAP180 is weatherproofed against rain. Also, prolonged heavy rain has no

significant effect on the radio signal. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection. If moisture enters a connector, it may cause a degradation in performance or even a complete failure of the link.

z Snow and Ice — Falling snow, like rain, has no significant effect on the radio signal.

However, a build up of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be cleared from the antennas to restore operation of the link.

Ethernet Cabling

When a suitable antenna location has been determined, plan a cable route from the

OAP180 outdoors to the power injector module indoors. Consider these points:

z The Ethernet cable length should never be longer than 100 ft. z Determine a building entry point for the cable. z Determine if conduits, bracing, or other structures are required for safety or protection

of the cable.

z For lightning protection at the power injector end of the cable, consider using a

lightning arrestor immediately before the cable enters the building.

z The shield of the ethernet cable needs to be grounded at the lightning arrestor. If, by

design, the lightning arrestor cannot provide this ground, the shield of the ethernet cable will need to be grounded by the installer.

Grounding

A r t s

It is important that the OAP180, cables, and any supporting structures are properly grounded. The OAP180 unit includes a grounding screw to attach a ground wire. Be sure that grounding is available and that it meets local and national electrical codes.

Test Basic Link Operation

Set up the OAP180 on the ground, either outdoors or indoors. Connect the unit as indicated in this document and perform the basic configuration tasks outlined below.

When you are satisfied that the OAP180 is operating correctly, proceed to mounting the unit in the intended location.

The Ethernet Link LED blinks green when a link has been detected and is in use.

Antenna Gain Recommendations

The OAP180 auto-adjusts the power level sent from the radio to the antenna, so that the EIRP emitted from the antenna is the value defined by the controller (100mW by default). You can increase this setting if you are compensating for signal loss from long inexpensive cables connecting external antennas. (Configure a false/low dBi antenna gain to trick the radio into supplying more transmit power to that antenna, which would then make up for the cable loss.) You may also need to decrease the EIRP from 100mW to 30mW for a device that only transmits at 30mW. The Antenna Gain values can be changed from the Web UI Configuration>APs>Antenna Properties view, or from the CLI using the antenna- property command. Determine the appropriate gain for your antenna by checking the following chart.

Installing the Access Points

Selecting a Location

The AP150 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 can obtain their power from 802.3af standard Power over Ethernet (PoE)-compatible network switch or PoE power injector installed between the switch and the AP150.

Installing the Access Points

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:

environment. Place access points accordingly.

The AP150 is only intended for installation in Environment A as defined in IEEE

1. Remove the attached mounting bracket from the back of the AP150.

2. Mark the location on the wall for two mounting screws. They are placed 4.3"

apart, center-to-center, or one above the other. If you are not using plastic wall anchors, you must either center the mounting screws on a wall stud or use plastic wall anchors.

3. Drill holes at the locations you marked:

— 3/16-inch holes if you are using plastic anchors — 1/8-inch holes if you are using only the screws

Installing the Access Points

4. If you are using plastic anchors, install them in the holes.

5. Screw in the screws most of the way, so that the screw head is about 1/16 of an

inch from the wall.

6. Align the AP150 keyholes over the mounting screws and slightly pull down (or across, if mounting sideways).

7. For external antennas, loosen the knurled ring at the base of each antenna (see

Figure 33), point the antenna straight up, then retighten the ring.

8. Connect one end of the PoE 100BaseT Ethernet cable to the 100/1000 Ethernet connector, shown in Figure 34.

Vertical Mounting with the Mounting Bracket

The AP150 uses thumbscrews to attach to the mounting bracket or mounting plate that allows the access point to be mounted on a vertical surface. Additionally, three shoulder screws may be installed on the mounting bracket to allow the AP150 and attached bracket to mount over a previously installed Cisco 1200 mounting bracket.

To vertically mount an AP:

1. If not mounting the AP150 to a previously third-party installed mounting bracket, use a 1/8" Allen wrench to remove the shoulder screws from the mounting bracket, if already attached.

2. Using the bracket holes as a template, remove the bracket from the AP150 (or use the stencil in Appendix C, “Mounting Bracket Stencils”) to mark the location on the wall for the two AP bracket mounting screws. They are placed 4.3 inches apart, center-to-center. If you are not using plastic wall anchors, you must center the mounting screws on a wall stud. If you do not center the mounting screws on a wall stud, you must use plastic wall anchors.

About an Hoffman/NEMA Enclosure Installation

The recommended RS4000 installation is a wall mount, but if necessary the RS4000 can be housed inside a protective NEMA or Hoffman box that is manufactured with external corner tabs for standard wall mounting, above or below a ceiling. When installing in the Hoffman/NEMA box, the RS4000 attaches to an optional Hoffman/NEMA box mounting plate, which replaces the standard wall mount bracket.

Caution!

Laboratories.

Meru leaves the placement and orientation of the Hoffman/NEMA enclosure to the customer. It will be necessary to drill holes through the plastic NEMA enclosure with a Meru-provided template to enable the antenna and Ethernet cabling to exit the enclosure. Instructions for performing this task are provided in the section “Creating
