1 Product Overview

Thank you for using the ENH202. It is a powerful and enhanced business-class product with 4

multi-functions: Access Point, Client Bridge, WDS, and Client Router.

EnGenius’ ENH202 uses the latest wireless standard, 802.11n, which allows for faster wireless

throughput. The ENH202 affords a great advantage to minimize the time and cost which is

required to expand your network. It operates at 2.4GHz and is also backwards compatible with

802.11b/g networking equipment.

The ENH202 is easy to install almost anywhere with included proprietary Power over Ethernet

adapter for quick outdoor installation. In addition, the ENH202 can manage power level

control, and it features narrow bandwidth selection, traffic shaping and real-time RSSI

indication. The ENH202 fully supports wireless encryption including Wi-Fi Protected Access

(WPA-PSK/WPA2-PSK), (64/128/152)-bit WEP Encryption, and IEEE 802.1x with RADIUS.

Additionally, the ENH202 is an ideal choice to pair with the ENH202 in an Access Point – Client

Bridge or WDS Bridge – WDS Bridge topology.

The ENH202 utilizes a proprietary PoE adapter. Only use the supplied PoE

adapter. Damage may occur if another PoE adapter is used.

1.1 Features

The following list describes the design and scope of the ENH202 made possible through the

power and flexibility of wireless LANs:

a) Difficult-to-wire environments

There are many situations where wires cannot be laid easily. For example, historic

and older buildings as well as open areas and cross-street architectures make the

installation of LANs either impossible or very expensive.

b) Temporary workgroups

Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery,

temporary offices and construction sites where one wants a temporary WLAN

established and removed at a future date. The ENH202 is easy to place into and

remove from production.

c) The ability to access real-time information

Doctors and nurses, point-of-sale employees, and warehouse workers can access

real-time information while dealing with patients, serving customers, and

processing information.

d) Frequently altered environments

Show rooms, meeting rooms, retail stores, and manufacturing sites are prime

examples where frequently rearranged workplaces are suited for wireless LANs.

e) Wireless extensions of Ethernet networks

Network managers in dynamic environments can minimize the overhead caused by

moves, extensions to networks, and other changes by utilizing wireless LANs.

f) Wired LAN backup

Network managers may implement wireless LANs to provide redundancy for

mission-critical applications which are implemented on wired networks.

g) Training and educational facilities

Training sites at corporations and students at universities use wireless connectivity

to afford access to information, information exchanges, and learning.

2 Installation

This chapter describes how to install the ENH202.

Only experienced installation professionals who are familiar with local building and

safety codes and, wherever applicable, are licensed by the appropriate government regulatory

authorities should install the ENH202.

2.1 Pre-installation Guidelines

Select the optimal locations for the equipment using the following guidelines:

- The ENH202 should be mounted on a 1"- 4" pole. Its location should enable easy access

to the unit and its connectors for installation and testing.

- The higher the placement of the antenna, the better the achievable link quality.

- The antenna should be installed to provide a direct or near line of sight link with the base

station antenna. The antenna should be aligned to face the general direction of the base

station.

2.2 Installing the ENH202

To install the ENH202, use the following procedure to mount the device on a pole and refer to

the figure below.

1. The bottom of the ENH202 is a removable cover. Grab the cover and push down

slightly while pulling it backward to remove the cover.

2. Insert a standard Ethernet cable into the RJ-45 port labeled MAIN LAN.

3. Slide the cover back to seal the bottom of the ENH202.

4. Remove the power cord and PoE injector from the box and plug the power cord

into the DC port of the PoE injector.

Only use the power adapter supplied with the ENH202. Using a different

power adapter might damage the ENH202.

5. Plug the other side of the Ethernet cable in Step 3 into the PoE port of the PoE

injector. When you finish Step 5, the installation will resemble the following picture.

6. Turn over the ENH202. Then insert the mast strap through the middle hole of the

ENH202. Use a screwdriver to unlock the pole-mounting ring putting it through

the ENH200.

7. Mount the ENH202 securely to the pole by locking the strap tightly.

This completes the installation procedure.

3 Wireless Network Modes

3.1 Access Point Mode

In the Access Point Mode, the ENH202 functions like a central connection for any stations or

clients that support the IEEE 802.11b/g/n standards. Stations and clients must utilize the same

SSID and Security Password to associate while within range. The most suitable topology for

this mode is to have one ENH202 as an AP and the second one as a Client-Bridge – when

necessary a third Client-Bridge can be place within the directional antenna’s path. One

advantage of using the ENH202 to create point-to-point outdoor wireless links is when the

environment is prone to radio interference on 5GHz band. Running the network on 2.4GHz

can avoid the interference, thus providing higher stability to the network.

3.2 Access Point with WDS Function Mode

The ENH202 also supports WDS functionality while in Access Point Mode. Simply configure

other Access Points and the associated MAC addresses in order to enlarge the wireless area by

enabling WDS Link Settings. WDS functionality can support up to 8 different AP MAC

addresses. Please note that this mode is rarely used due to the nature of directional antennae.

Consequently, the wireless clients need to be located in the path of the ENH202’s directional

antenna and be within in the range to send signal back to the ENH202.

Not every Access Point supports WDS in Access Point Mode. It is

recommended to use ENH202s if you would like to utilize this functionality.

3.3 Client Bridge Mode

In the Client Bridge Mode, the ENH202 functions like a wireless client, connecting to an

Access Point wirelessly and enabling Internet connectivity wherever you want. Use Site Survey

function to scan all of the Access Points within range and configure the SSID and Security

Password to associate with it. With Client Bridge Mode, the ENH202 works as long range

2.4GHz wireless-Ethernet Bridge in order to provide a 2.4GHZ link between the access point

and networked clients.

3.4 WDS Bridge Mode

In the WDS Bridge Mode, the ENH202 can wirelessly connect different local area networks by

configuring each device’s MAC address and security settings. The WDS Bridge Mode can

bridge up to four local wired networks together as one logical network. Every computer on

this logical network can see each other, sharing files as if they are in the same location. With

600mW output power and MIMO antenna technology, the connection distance can extend

beyond 1000 feet with good performance, assuming the antenna are within line of sight. The

WDS bridge network is a MAC-based network that provides transparent bridging.

WDS Bridge Mode is unlike Access Point Mode. APs linked by WDS are

using the same wireless channel, and connecting excessive numbers of APs on the same

channel may result in lower throughput. Please be aware to avoid loop connections;

otherwise enable the Spanning Tree Function.

3.5 Client Router Mode

In Client Router Mode, the ENH202 provides two functions: 1) acting as a wireless-Ethernet

Bridge in order to relay signal from the access point; 2) acting as an active DHCP server that

allows WLAN clients to share the same wireless network connection. Ideally, have clients

wirelessly connect to an AP/WISP and connect to LANs via Ethernet. Client Router Mode is

different from the AP Router Mode. It is not a common application however useful when

connects to WISP AP.

4 Configuring Your Computer for TCP/IP

This chapter describes how to configure the TCP/IP settings on a computer that will be used

to configure the ENH202. Because the default operating mode is Client Bridge, an IP address

will not be assigned to the computer/notebook. Therefore, follow the steps below to assign

an IP address to a client’s Ethernet adapter.

4.1 Configuring Microsoft Windows 7
