IRVINE, California, May 7 /PRNewswire/ --

RF Digital, a manufacturer of specialized wireless subsystems, today
announced the first Wi-Fi module (Model Number RFD21715) that can provide up 
to a decade of battery life in a breakthrough form-factor package 
approximately 1 X 1 inch. The extremely low power of the RFD21715 is based on 
GainSpan Corporation's(TM) GS1010 802.11 SoC which is key in providing the 
extended battery life. Lengthy battery life opens up a raft of potential 
applications, such as building automation, utilities metering, telemetry and 
transportation, and supply chain management.

"Our customers will now be able to create an array of exciting products
that leverage the existing ubiquitous Wi-Fi infrastructure while extending
the battery life for sensors and other connected devices from 5 to 10 years,"
said Armen Kazanchian, CEO of RF Digital. "Utilizing GainSpan's innovative
solutions, we were able to get the RFD21715 to market quickly and provide our
customers with new capabilities previously not available."

With the RFD21715's small form-factor and flexible interface, OEMs can
quickly and easily engineer products with Wi-Fi capabilities that will reduce
energy consumption, cut costs and improve efficiency because they are used on
the existing infrastructure. The product integrates an application sub-system
that is supported by a Software Development Kit (SDK) which is available from
RF Digital and GainSpan. The SDK integrates a robust RTOS, network stack,
Wi-Fi and I/O services that compress customer application development
time by nine to twelve months.

Other key features of the new RFD21715 module include AES encryption,
TCP/IP (IPv4), UDP, DHCP, and SNMP which provides for remote device
configuration and management.

"We are very happy to be partnering with RF Digital. The company has a
unique ability to reach a broad range of customers in the commercial and
industrial markets -- the same segments we've been targeting," said Vijay
Parmar, CEO and president of GainSpan. "In addition, we've been very
impressed with how quickly RF Digital not only designed the product but also
got it ready for production shipment. RF Digital's module will expand
deployment of Wi-Fi sensor networks by speeding OEMs' time to market."

The RFD21715 is available worldwide during the second half of 2008. For
