About This Guide

This guide details how to install a Juniper Networks Access Point (AP), models

WLA620, WLA622, and WLA632, in a Juniper Networks Mobility System™ wireless

LAN (WLAN). The WLA620, WLA622, and WLA632 are suitable for installation

outdoors.

This guide is intended for

network administrators or others involved in installing

APs in a network.

Juniper Networks Mobility System

The Juniper Networks Mobility System is an enterprise WLAN solution that

seamlessly integrates with an existing wired enterprise network. The Juniper

Networks system provides secure connectivity to both wireless and wired users in

large environments such as office buildings, hospitals, and university campuses.

The Juniper Networks Mobility System fulfills the three fundamental requirements of

an enterprise WLAN: it eliminates the distinction between wired and wireless

networks, allows users to work safely from anywhere (secure mobility), and provides a

comprehensive suite of intuitive tools for planning and managing the network before

and after deployment, greatly easing the operational burden on IT resources.

The Juniper Networks Mobility System consists of the following components:

 RingMaster tool suite—A full-featured graphical user interface (GUI) application

used to plan, configure, deploy, and manage a WLAN and its users

 One or more Wireless Lan Controller (WLC ) —Distributed, intelligent machines

for managing user connectivity, connecting and powering Mobility Point (MP)

access points, and connecting the WLAN to the wired network backbone

 Multiple Mobility Point Access Points (AP™) —Wireless APs that transmit and

receive radio frequency (RF) signals to and from wireless users and connect them

to an WLCswitch

 Mobility System Software™ (MSS™)—The operating system that runs all WLC

switches and APs in a WLAN, and is accessible through a command-line interface

(CLI), the Web View interface, or the RingMaster GUI

WLA620, WLA622 and WLA632

Overview

 A Juniper Networks model WLA620 provides IEEE 802.11 wireless access to the network.

WLAs are designed for use with a Juniper Networks WLAN controller. WLAs require

hardware installation only. All configuration for an WLA is performed on the WLC.

Hardware Overview

WLA620

The WLA620 provides wireless access point services for clients in the local LAN area,

and can provide point-to-point or point-to-multipoint wireless bridge links between

remote Ethernet LANs. The WLA is housed in a weatherproof enclosure for mounting

outdoors and includes brackets for attaching to a wall, pole, radio mast, or tower

structure. The unit is powered through an Ethernet cable connection from a power

injector module installed indoors. The WLA620 provides a 54 Mbps half-duplex

connection for each active channel.

A wireless bridge system offers a solution for connectivity between remote Ethernet

wired LANs, or to provide Internet access to an isolated site where a wired link may be

difficult or expensive to deploy. The wireless bridge connection provides data rates of

up to 108 Mbps.

Radio Characteristics – The IEEE 802.11a and 802.11g standards use a radio

modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM),

and a shared collision domain (CSMA/CA). The 802.11a standard operates in the 5

GHz Unlicensed National Information Infrastructure (UNII) band, and the 802.11g

standard in the 2.4 GHz band.

IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE

802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread Spectrum

(DSSS) and Complementary Code Keying (CCK) modulation technology to achieve a

communication rate of up to 11 Mbps.

Warning: Installation must be performed by qualified service personnel only. Read and

follow all warning notices and instructions marked on the product or included in the

documentation. Before installing the product, read the Regulatory Guide document.

Informational Note: The WLA radios are disabled by default and can be enabled only by

a system administrator using the WLC.

WLA620, WLA622 and WLA632 Overview

WLA622

The WLA622 provides only external antenna options and is designed to operate as the

“root bridge” in point-to-multipoint configurations, supporting wireless bridge

connections to as many as six units. The WLA is housed in a weatherproof enclosure

for mounting outdoors and includes brackets for attaching to a wall, pole, radio mast, or

tower structure. The wireless bridge connection provides data rates of up to 54 Mbps. A

WLC cannot be used to power the outdoor WLA. The WLA requires a Juniper-designed

XPS power supply for proper operation.

WLA632

The WLA632 is a 802.11a/b/g/n WLA that is designed for pole-mounting and wall

mounting. The WLA632 supports 6 antenna ports, 3 for the 11a/n radio and 3 for the

11b/g/n radio. Antennas other than Juniper approved antennas are not supported. The

WLA632 does not support internal antennas or PoE. A WLC cannot be used to power

this WLA. A WLA-XPS9001GO power supply that uses the IP67 multi-pin DIN

connector is required. The WLA-XPS9001GO is specifically designed for the WLA632

and is available from Juniper Networks.

Informational Note: The power injector module does not support Power over Ethernet

(PoE) based on the IEEE 802.3af standard. The WLA620 must always be powered on by

being connected to the power injector module.

WLA620, WLA622 and WLA632 Overview

The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can

therefore use straight-through twisted-pair cable to connect this port to most network

interconnection devices such as a switch or router that provide MDI-X ports. However,

when connecting the access point to a workstation or other device without MDI-X ports,

you must use crossover twisted-pair cable.

Figure 1–3. Power Injector Module

The WLA620 does not have a power switch. It is powered on when the Ethernet port is

connected to the power injector module, and the power injector module is connected to

an AC power source. The power injector includes one LED indicator that turns on when

AC power is applied.

The power injector module automatically adjusts to any AC voltage between 100-240

volts at 50 or 60 Hz. No voltage range settings are required.

Receive Signal Strength Indicator (RSSI) BNC Connector

The RSSI connector provides an output voltage that is proportional to the received radio

signal strength. A DC voltmeter can be connected the this port to assist in aligning the

antennas at both ends of a wireless bridge link.

Grounding Point

Even though the WLA620 includes a built-in lightning protection, it is important that the

unit is properly connected to ground. A grounding screw is provided for attaching a

ground wire to the unit.

Wall- and Pole-Mounting Bracket Kits

The WLA620 includes bracket kits that can be used to mount the unit to a wall, pole,

radio mast, or part of a tower structure.

Lightning Protector for Outdoor Antenna

If you are using the WLA620 with an outdoor antenna, Juniper Networks recommends

installing an external lightning protector for the antenna. An external lightning protector

may be obtained from Juniper Networks.
