802.11b Wireless Outdoor AP+Bridge (ODU) - Model: WH-9200

E-mail Print

The WH-9200 11Mbps Wireless Outdoor Bridge Solution is a complete, easy-to-install, and easy-to-manage building-to-building connectivity package. It includes 11Mbps Wireless Outdoor Bridge and an integrated high-gain antenna in a weatherproof enclosure, mounting accessories, power adapter, power-over-Ethernet (PoE) injector, and weatherproof Ethernet and antenna cables. Able to deliver three to four times the bandwidth of a T1 line at a fraction of the operating cost, the WH9200 relieves organizations of the need to contract with service providers for medium-distance links. This solution is ideal for cross-campus links and for connecting portable or temporary classrooms at distances up to 20 kilometers (12.5 miles).

The WH-9200 provides all the interoperability, expandability, security, and manageability that modern high-performance wireless networks demand.

Key Features and Benefits:

IEEE 802.11b Compliant
Complies with the IEEE 802.11b wireless networking standard, ensuring full interoperability with other 802.11b compliant products.

Superior Coverage and High Signal Quality

The advanced radio-frequency technology and high-gain integrated antenna provide outstanding performance at data rates up to 11 Mbps and distances up to 20 kilometers (12.5 miles).

Superior receiver sensitivity enhances pickup of weak data signals over greater distances

Rugged design, proven in outdoor installations subject to high winds, heavy rain, and snow

Remote Configuration
Allows administrators to manage the bridge from anywhere on the network. All that is required is that the bridge be on the same logical IP subnet as the management station.

Comprehensive Network Management Tools
Full-featured Windows-based SNMP software included the Instant Wave Management System (IWMS)

Robust discovery mechanism:
- Auto IP address assignment the WH9200 will automatically assign itself a new IP address should the DHCP server fail.

- Bridge discovery allows quick location of all Instant Wave bridges for centralized management.

Protocol filtering: saves bandwidth and increases security by preventing the bridge from transmitting specified protocols from the wired Ethernet LAN into the wireless zone.

On-line firmware upgradability: allows the bridge  firmware to be upgraded via IWMS from a remote station without stopping the network.

Trap server: with auto-notification, network administrators can easily monitor operating conditions and take preventive action to ensure maximum network uptime.

DHCP client support: automatically obtains a new IP address from a DHCP server.

Bulk configuration: automatically propagates configuration settings to multiple bridges on the same subnet .

Multi-level Security
WEP (Wired Equivalent Privacy): 64- and 128-bit WEP encryption for secure wireless LAN data transmissions. .

SNMP access control: SNMP authentication prevents unauthorized tampering with bridge settings.

Antenna Alignment Monitoring
When using directional antennas for bridge-to-bridge links, manual alignment of the antennas for proper operation is a must. The WH9200 performs intelligent antenna alignment monitoring for quick, convenient, and accurate alignment.

Integrated Antenna
Factory integration of the 18-dBi high-gain antenna and bridge circuit module in a weatherproof enclosure ensures ease of installation and many years of trouble-free operation.

Full Outdoor Protection
The weatherproof housing, cables, and connectors will stand up to the harshest weather conditions, including high winds, heavy rain, and snow.

Power Over Ethernet
PoE carries both data and power to the bridge through a single Ethernet cable, eliminating the need for a separate power cable and making installation easier and more economical.

11Mbps Wireless Outdoor Bridge Application Scenarios

Point-to-point Mode

Bridges in point-to-point mode connect two networks in different locations through a single wireless link. This allows two widely separated sites to share resources, including a single high-speed connection to the Internet.

Point-to-multipoint Mode

A bridge in point-to-multipoint mode can connect three or more networks in scattered buildings through wireless links. This allows numerous sites in a wide area to share resources, including a single high-speed connection to the Internet.
