Redpine Signals, Inc. has introduced Wi-Fi real time location system (RTLS) tags operating in the 5 GHz band. The WiseMote™ WM1-20 (2.4 GHz) and WM1-50 (2.4/5 GHz) 802.11n Wi-Fi RTLS tag devices work with any third-party hardware and software RTLS infrastructure.
Offering Wi-Fi security and single stream 802.11n operation, the new tags can be deployed in enterprise environments. According to the manufacturer, operation in the 5 GHz band provides for close adherence to designed battery life compared to 2.4 GHz channels. The operating profiles of tags and sensor nodes involve long periods of sleep with low power consumption interspersed with brief periods of activity. Traffic on the channel extends the periods of activity as the Wi-Fi devices wait for a chance to transmit.
The Redpine devices can be programmed to operate in a variety of modes, supporting multiple location tracking and update mechanisms. In Cisco Compatible Extensions (CCX) mode, they offer Cisco CCX compliant beaconing with configurable patterns, telemetry and alarm notifications. In Wi-Fi associated mode, they periodically connect to access points and communicate sensor and channel data to a server. In other beaconing modes, the devices support standard Wi-Fi clients with simple tag identification software to locate and identify assets.
Redpine is also releasing the WModem tag configurator and chokepoint device with low frequency excitation circuitry and an automated wireless configuration solution, creating a hardware and software infrastructure that enables third-party RTLS solution development.
