USB WiFi Modem Module Affordably Meets Fastest Wireless Protocols For OEM Purposes

Radicom's USB WiFi Module Supports 802.11b/g/n Standards At Extreme Operating Temperatures

SAN JOSE, Calif. May 18, 2011 Radicom Research, a leader in the modem industry, announced today the release of WiFiHU series of USB WiFi modem modules. With the WiFiHU modules, WiFi connectivity can easily be added to virtually any processor-based device. WiFiHU supports the latest wireless standards, including 802.11b/g/n, all through a USB 2.0 interface, at a price normally found for last-generation wireless hardware.

With reliable transmissions, protocol stack and use of 1TX/2RX antenna technology, these high speed USB wireless devices achieve over-the-air data throughput up to 300Mbps downstream and 150Mbps upstream PHY rates using 40MHz bandwidth or up to 150Mbps downstream and 75Mbps upstream rates using 20MHz.

The WiFiHU is designed for industrial OEM use.  It features 40C to +85C extended operating temperatures in a small footprint, and it comes with WEP/WPA/WPA2 security protocols to protect the host. Other specifications include firmware and configuration parameters stored in on-board NVRAM and low overall power consumption.

Radicom's WiFiHU series comes in two models: WiFiHU-a and WiFiHU-c. WiFiHU-a has dual-chip antennas built in to eliminate the need for costly and time-consuming RF development, creating shorter time to market. WiFiHU-c has two U.FL connectors to attach antenna cables and antennas, giving OEM engineers the flexibility to place antennas in locations best suited to their design.
