Redpine Signals Launches First 802.11n Single Stream Module for Wi-Fi Based Real

Time Location Systems (RTLS)

SAN JOSE, Calif., Apr. 20 /PRNewswire-AsiaNet/ --

          Redpine's Find-iT CCX-compliant Wi-Fi 802.11n RTLS Tag Offers

                Versatility, Ultra Low Power, High Data Rates

    A new module for supporting WiFi(R) RTLS tags from Redpine Signals(R),

Inc., offers the first 802.11n single stream solution for asset tracking.

Redpine's Find-iT(TM) module provides all the control and wireless

functionality required to build and deploy tags for advanced two-way

communicating real-time location systems (RTLS) in industrial and enterprise

applications. The module is also the first 802.11n solution to meet Cisco

Compatible Extensions (CCX) tag specifications for system designs for the

Cisco Location Solution. Redpine is a leading developer of ultra low power

multi-standard OFDM and MIMO silicon-based solutions for Wi-Fi, mobile


    Redpine's Find-iT module is based on the company's ultra low-power

Lite-Fi(TM) 802.11n technology to offer higher throughput at lower power.

This opens up opportunities for new applications, such as transfer of large

image data from an asset to the central station, that were not possible in

the traditional RFID space where the high data rates and two way

communication were not present. Redpine's participation in Cisco's

CCX-certification program enables developers using the Find-iT

(RS9110-N-11-51) module to take advantage of innovations in accuracy,

telemetry and network management delivered by Cisco and its technology


    The Find-iT module is a complete foundation for solutions targeting the

fast-growing field of standard Wi-Fi based asset tracking and identification

called WFID. The use of Wi-Fi for Active RFID tags enables enterprises that

deploy them to make use of available wireless infrastructure, while

simultaneously providing higher operational range and positional accuracy.

The module is built for extremely low power consumption using system-level

and profile-driven fine-grained power control, a microcontroller with an

ultra low-power mode working off a low-frequency clock source, and a WLAN

subsystem with multiple power modes.

    The module's versatility lies in its ability to work with various RTLS

mechanisms such as 1) waking up at periodic intervals, receiving packets or

beacons from different Access Points and sending the RSSI of each beacon to a

central server; or 2) transmitting a predetermined data packet at periodic

intervals so that customized receivers can calculate RSSI or time of arrival/

time difference of arrival (TOA/TDOA) of these packets for further

processing. Apart from sending preset data, the Find-iT module can also

process and send out data received on its various interfaces - including

analog, SPI, I2C, and GPIO lines. Its extremely low average power consumption

is aided by the ability to continue in a sleep mode until awakened by events

such as a time-out or a sensor input.

    The Find-iT module implements standards compliant 802.11 functionality

and is able to connect to standard Access Points in open or secure modes. It

provides a network stack that originates or terminates TCP/IP and UDP

connections with IPv6/IPv4 capability. The integrated microcontroller

implements a small footprint embedded operating system on which multiple

Science Information Technology Redpine Signals, Inc. 2 image

applications can be built. The 31mm x 44mm QFN module also includes a

built-in antenna, frequency reference, power management, and flashed-in

firmware, with overall configuration made available through UART or wireless.

    "Our Find-iT module is the ideal platform for building emerging location

solutions," said Venkat Mattela, CEO of Redpine Signals. "As enterprise and

industrial networks rapidly embrace the 802.11n standard, universal client

adoption of the 802.11n protocol is required to take advantage of enhanced

throughput in 11n networks. It just doesn't make sense today to design Wi-Fi

RTLS solutions using legacy 802.11 b/g protocols," he added.

    With a single 3V, 2000 mAh battery, and uploading location data every two

minutes, the module can achieve over five years of battery life in a

CCX-compliant infrastructure. The high-performance WLAN subsystem in the

module further enhances range and effectiveness of data transfer, at the same

time providing energy savings.

    The Find-iT module is sampling now; and a fully implemented evaluation

board with configurable software is also available.

    The Find-iT module will be demonstrated at Redpine Signals' booth # 4Q13

at the RFID World Asia 2009 Conference being held at Suntec Convention

Center, Singapore, from April 22 to April 24, 2009. Interested parties may

schedule a private demo and meeting with Redpine executives at the conference

or at a later date by sending an email to
