Redpine champions 5GHz WiFi for M2M
April 03, 2012 // Nick Flaherty
M2M networks will increasingly use 5GHz WiFi technology as the 2.4GHz band becomes overcrowded and security becomes vital, says the CEO of module supplier Redpine Signals, Venkat Mattela.
With enterprise security and single stream 802.11n operation, the new tags are ideal for deployment in enterprise environments. Operation in the 5 GHz band provides for close adherence to designed battery life compared to crowded 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.
Even a moderately busy channel can reduce the battery life of Wi-Fi devices. This can disrupt the deployment, management and maintenance planning of asset tracking and monitoring in an enterprise. Moving to the 5 GHz band is not only for high throughput, QoS sensitive applications, but is also an important step for long battery life applications, said Mattela. Our goal with our new products is to offer advanced ultra low power Wi-Fi technology in 5 GHz as well as an RTLS architecture that enables our partners to provide their own value to the total solution and ultimately accelerate RTLS deployments worldwide.All news
