The Wireless Broadband Router is a long-range, high performance wireless LAN product, which provides Access
Point services to a 2.4 GHz RF network and bridges to an Ethernet backbone and routes to an Ethernet WAN port.
The Wireless Broadband Router performs all the necessary inter-networking, bridging and routing functions. It
receives data from both networks, stores them locally for further processing, installs and maintains connections, and
transmits the packets to the proper destination.
The Wireless Broadband Router connects computers and laptops to your local network through wireless connection.
The Radio Frequency (RF) waves link the wireless clients to the Access Point, and the Access Point works as a
bridge between the wireless clients and the wired LAN or Ethernet clients.
The Wireless Broadband Router is compliant with the IEEE 802.11 / IEEE 802.11b DSSS specification and is Wi-Fi
certified. Thus all wireless clients, even from different vendors, that meet the 802.11b standard can access your
Ethernet network through this Wireless Access Point. Also, with throughput performance of up to 11 Mbps, the
wireless connection is as efficient as the wired connection. The wireless LAN security is provided through its WEP
(Wireless Equivalent Privacy) support.
Wireless Broadband Router has 4 10/100 Mbps switch ports. This switching automatically detects the speed of the
device that you plug into it and routes it to the appropriate port.
