Meru Networks, which provides 802.11n virtualized wireless LAN (WLAN) solutions for enterprise networking, has been awarded two new patents for its innovation addressing Layer 2 network congestion collapse in 802.11n WLANs. Users that introduce iPads, iPhones and other wireless devices in the enterprise expect an interactive experience while accessing their latency-sensitive voice, high-bandwidth video and data applications, regardless of the number of mobile devices on the Wi-Fi network. However, existing rate adaptation technologies often lead to significant reduction in the network speed experienced by users.
The rate adaptation frameworks and methods covered in Meru’s Patent no. 7,808,908 and Patent no. 7,756,059 enable the delivery of critical enterprise applications at the optimal transmission rate for each device, taking into account network congestion, loss rate of the channel, and the distance and mobile or stationary state of the device.
