MP-622 Overview 1 - 1

MP-622 Overview

A Trapeze Networks Mobility Point (MP) model MP-622 provides IEEE 802.11 wireless access to

the network. MP access points are designed for use with a Trapeze Networks Mobility Exchange

(MX). MPs require hardware installation only. All configuration for an MP is performed on the

MX.

Hardware Overview

The MP-622 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 MP 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.

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 54 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.

The MP-622 provides a 54 Mbps half-duplex connection for each active channel.
