![]() MIMO generally operates in two modes: diversity mode and spatial multiplexing mode. The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed. It’s an antenna technology for wireless communications in which multiple antennas are used at both the transmitter and the receiver. MIMO stands for multiple input multiple output. The BeamFlex technology alone extends the range and throughput of standard 802.11 clients by 200 to 300 percent. The massive diversity of the BeamFlex antenna systems allows RUCKUS devices to find and instantly select from many quality signal paths in a changing environment to sustain the baseline performance required for data, voice and video applications. By selecting the optimum antenna pattern for each receiving device, BeamFlex enables better signal quality and higher communications speeds over the 802.11 Wi-Fi network. This knowledge enables the BeamFlex antenna array to reconfigure itself in real-time, detecting and adjusting for both spectral and multipath interference as well as neighbor network noise. The BeamFlex expert system control software continuously ranks the optimum antenna patterns for each receiving device, using the inherent feedback mechanism built into the 802.11 MAC layer protocol. The newest RUCKUS product is equipped with a compact, internal antenna array with twelve high-gain, directional antenna elements capable of forming 4096 unique antenna patterns for massive diversity. Unlike all other approaches, BeamFlex gives users all the benefits of MIMO without the cost or complexity. For example, any 802.11 b/g client station that associates with a BeamFlex powered AP can instantly benefit from the increased range and throughput, with no configuration changes required on the client. BeamFlex applies MIMO diversity techniques to standards-based 802.11 a/b/g/n technologies to eliminate dead spots, increase range and performance for all standard 802.11 devices. Is BeamFlex a standards-based technology? This has been the central problem that has plagued Wi-Fi from being the universal networking infrastructure for all voice, video and data communications in the home. In turn, off-the-shelf wireless solutions aren’t suitable for IPTV over Wi-Fi. Most urban home environments are very “noisy” with microwave ovens, cordless phones and neighbor Wi-Fi noise – all of which introduce interference and degrade wireless transmissions. While it is possible to use off-the-shelf APs and adapters for wireless video streaming at very short distances (less than 20ft / 6m), most homes and apartments do not benefit from such conditions. Can’t I just use any Ethernet-equipped access point and adapter for Wi-Fi video? SmartCast ensures that different traffic types are each handled according to their specific requirements.Ĭombined, SmartCast and BeamFlex provide the predictable performance needed for picture-perfect multimedia content delivery. SmartCast is a very sophisticated traffic inspection and classification engine that provides a number of unique functions such as remote RF monitoring, quality of service and application-aware content parsing. BeamFlex steers RF signals around interference to eliminate Wi-Fi dead spots while increasing the range and performance of the Wi-Fi network. The result is an intuitive Wi-Fi system that continuously ranks the best antenna pattern for each receiving device, constantly reconfiguring itself in real-time as interference is encountered. It combines a compact internal antenna array with expert system control software. They are patent-pending smart antenna and RF traffic engineering technologies (respectively) embedded into every RUCKUS system.īeamFlex is MIMO smart antenna technology and represents the industry’s most advanced multiple input/multiple output (MIMO) antenna implementation of its kind.
