Low Cost Easy-to-Integrate Module Provides 802.11n Wireless Connectivity for the Industrial Market San Jose, CA — Jan. 20, 2009
— Redpine Signals, Inc., a leading developer of ultra low power multi-standard OFDM and MIMO silicon-based solutions for Wi-Fi®, WiMAX® & LTE, today announced the availability of a pair of serial wireless device server modules based on its ultra low-power Lite-Fi™ 802.11n technology. The modules provide industrial devices and other equipment with advanced wireless connectivity to local-area networks, enabling communication with the devices from servers anywhere on the local network or on the internet without the need to install wireless networking software or a network stack.
The modules offer complete functionality of a device server including the processing system with its networking stack and an 802.11n sub-system with communication, configuration, and control functions, a frequency reference, and an integrated antenna, along with a simple AT command interface for module configuration. The modules integrate the Lite-Fi™ RS9110 chipset, a highly integrated 802.11n SoC, an RF transceiver, power amplifier, EEPROM and external front-end components. The RS9110 SoC integrates a proprietary multi-threaded processor on which the WLAN protocol, configuration, power-save modes, operating system, network stack, and application functions are implemented. The modules provide outstanding ease of integration at low system cost, featuring a single 3.3V power supply, and the software to establish and terminate wireless connections.
The modules include the RS9110-N-11-21 and the RS9110-N-11-22 that operate in the 2.4GHz ISM band and have interfaces to coexist with other radios, such as Bluetooth, in the same band. The -22 module is a fully integrated device server with a complete TCP/IP networking stack, web server, WLAN driver, 802.11 enterprise security, and WLAN protocol running on the internal processor. It provides complete LAN and internet connectivity to equipment with a serial interface, and is ideal for M2M communications. The -21 module is a low cost device that provides secure WLAN connectivity to equipment or host systems that are connected to a network through a serial interface running SLIP. The -21 module originates or terminates SLIP connections, and provides connectivity to remote networks through the WLAN protocol. Both devices provide for termination of UDP connections and enable the collection, packetization, and transfer of external data from sensors or other special purpose devices connected via GPIO lines. The size of the modules is 35mm x 23mm and they support industrial grade temperatures (-40C to +85C). Apart from industrial equipment, POS systems, medical equipment, telemetry solutions, parking and utility meters, surveillance equipment, digital picture frames, and a host of other systems would benefit from these modules.
"Enterprise wireless networks are steadily moving towards widespread use of the 802.11n standard, with its attendant improvement in efficiency of spectrum use, higher user data rates, and longer range of operation. Preserving the capacity of an 802.11n network requires all clients, irrespective of their bandwidth needs, to use the 802.11n protocol. Our device server modules address precisely this need – providing a large variety of equipment with low-cost, single-stream 802.11n based network connectivity, with little or no integration effort," said Venkat Mattela, CEO of Redpine Signals. "These modules are based on our proven and highly integrated RS9110 SoC, which is the industry’s first single-stream solution to be Wi-Fi certified for the 802.11n draft 2.0 certification. The need for automation and flexibility of equipment deployment at low cost was never more needed than now in the industrial market, and the RS9110-N-11-21 and RS9110-N-11-22 modules are unique solutions in this fast growing market segment," he added.
