Redpine Signals Inc. has released a new module supporting Wi-Fi real-time location systems (RTLS) tags that offers an 802.11n single stream solution for asset tracking.

The Find-iT 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's Find-iT module is based on the company's low-power Lite-Fi 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.

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 also 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 OS on which multiple 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.

The Find-iT module is sampling now. A fully implemented evaluation board with configurable software is also available.
