Within the 5.15 to 5.25 GHz band (5GHz radio channels 34 to 48) the U-NII devices
are restricted to indoor operations to reduce any potential harmful interference to
MSS operations.
FCC Warning
FCC Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
FCC Caution
Any changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate this equipment.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator &
your body.
If this device is going to be operated in 5.15 ~ 5.25GHz frequency range, then it is restricted in indoor
environment only.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware
programmed at the factory to match the intended destination.The firmware setting is not accessible by the end user.

BROWAN COMMUNICATIONS Page 3
IC Warning
Operation is subject to the following two conditions:
This device may not cause interference and
This device must accept any interference, including interference that may cause undesired
operation of the device
This device has been designed to operate with an antenna having a maximum gain of 7dBi.
Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The required
antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the EIRP is not more than required for successful communication.
To prevent radio interference to the licensed service (i.e. co-channel Mobile Satellite systems) we
intended to operate this device indoors and away from windows to provide maximum shielding.
Equipment (or its transmit antenna) that is installed outdoors is subject to licensing.
Because high power radars are allocated as primary users (meaning they have priority) in 5250-5350
MHz, these radars could cause interference and/or damage to license exempt LAN devices.

BROWAN COMMUNICATIONS Page 7
Thank you for choosing the Browan 54Mb Dual-Radio Outdoor Access Point BW2250.
The Browan BW2250 operates simultaneously in the 5-GHz and 2.4-GHz frequency bands and is fully
compliant to 802.11b/g and 802.11a standard with its high performance and enhanced security.
BW2250 is an important part for the Browan Wi-Fi solution as 11a/b/g outdoor AP.
The two Dual-Band radios (a/g + a/g) that this product provides supplies the furthest in flexibility and
makes sure low interference and large coverage. The a+g operation mode and Multiple BSSID that
this product provides differentiates it from traditional outdoor AP product.
Product Overview
Flexibility and high performance
BROWAN BW2250 is a high-performance and high capacity and feature-rich outdoor AP/Bridge for
HotZone and backhaul services. The product’s dual tri-mode AP/Bridge radios architecture offers
spectrum and deployment flexibility to increase capacity and extend the range of HotZone Wifi
network.
zSimultaneously supports 802.11a and 802.11b/g for maximum client diversity
zMix of AP, AP Router and Bridge configuration: working simultaneously, blanketing last miles
with high-speed bandwidth.
zWireless AP router mode: Static Router table configure, NAT, Different IP subnet per BSSID,
Enable/Disable DHCP server or DHCP relay per BSSID.
zDual AP/ AP Router configuration: for high client density environment for both 802.11b/g and
802.11a users
zDual Bridge (repeater) configuration: serves to extend the transmission range of wireless
bridging and backhaul services.
Secure and reliable wireless networking

zIEEE 802.1x/EAP with password, certificates and SIM card
z64bits/128bits static and dynamic WEP encryption
zSupports Wi-Fi Protected Access (WPA/WPA2) with AES and TKIP support
zLayer 2 Isolation for preventing snooping on the same BSS
zMAC address filtering (ACL) for preventing illegal attacking from Internet
zHidden SSID broadcast to prevent illegal users connection
zBuilt-in Web login authentication (UAM)
Strong Anti-interference
Chapter 1 – Introduction

BROWAN COMMUNICATIONS Page 8
Dynamic Channel Allocation (DCA) solution automatically selects optimal operational frequency
channel during power up and the periodically monitors the environment and adjusts for best
operational channel. DCA enhances BW2250 performance and provide continuous coverage under
high AP density wireless network environment.
Dynamic Wireless Bridging
Dynamic Wireless Bridging capability enables BW2250 to automatically seek and discovery potential
nearby root AP, and dynamically self-configures for wireless bridge connection. With this feature in a
BW2250 network, whenever a bridge link is fail over, the network will auto reconfigure route
structures to minimize the lost of WLAN operation. It also minimized the technician intervention and
cost of going on-site to re-establish transmission paths. Since the birding fail over and restoration is
almost seamless, the perceptible interruption of WLAN subscribers is also minimized.
Multiple BSSID “Virtual AP” Technology
Supports up to16 BSSID per radio and each can be configured independently to support range of
security policies, authentication model, RADIUS servers and VLAN IDs. Each BSSID also can be set
different priority based on 802.1p tag or 802.11e EDCA which enables WLAN client device to access
wireless link QoS capabilities.
Ease Installation and Deployment
BW2250 enclosed in an aluminum-alloy frame-resistant with waterproof design housing operates
even under extreme weather conditions. Power option includes an integrated IEEE 802.3af Power-
over-Ethernet port enables effortless deployment in various environments. It also includes a special
Antenna Alignment Tool, which help to assist long-range wireless bridging installation to ensure the
optimal bridging performance.
Easy and Secure Remote Management
BW2250 supports secure remote management through HTTPS, CLISH and SNMP connections.
Web-based user interface with HTTPS request supplies secure remote management
BROWAN NMS product supplies the system management solution
Remote software upgrading via HTTPS
Detailed client survey and site survey
Bridge/Client Diagnostic Tools: optimize the installation for wireless bridging and optimize operation
status monitoring
Management Option
