1 Prod ct 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 tilizes a proprietary PoE adapter. Only se the s pplied PoE
adapter. Damage may occ r if another PoE adapter is sed.
1.1 Feat res
The following list describes the design and scope of the ENH202 made possible through the
power and flexibility of wireless ANs:
a) Diffic lt-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 ANs either impossible or very expensive.
b) Temporary workgro ps
Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery,
temporary offices and construction sites where one wants a temporary W AN
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) Freq ently altered environments
Show rooms, meeting rooms, retail stores, and manufacturing sites are prime
examples where frequently rearranged workplaces are suited for wireless ANs.
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 ANs.
f) Wired LAN back p
Network managers may implement wireless ANs to provide redundancy for
mission-critical applications which are implemented on wired networks.
g) Training and ed cational 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 G idelines
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 se the power adapter s pplied 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 proced re.
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 F nction 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 ink 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 s pports WDS in Access Point Mode. It is
recommended to se ENH202s if yo wo ld like to tilize this f nctionality.
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 nlike Access Point Mode. APs linked by WDS are
sing the same wireless channel, and connecting excessive n mbers of APs on the same
channel may res lt in lower thro ghp t. Please be aware to avoid loop connections;
otherwise enable the Spanning Tree F nction.
3.5 Client Ro ter 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 W AN clients to share the same wireless network connection. Ideally, have clients
wirelessly connect to an AP/WISP and connect to ANs 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 Config ring Yo r Comp ter 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
