Researchers working at the Massachusetts Institute of Technology<\/a> (MIT) have developed a more efficient way of coordinating multiple wireless broadband routers at the same time by using their new MegaMIMO 2.0 technology, which could deliver three times faster WiFi<\/a> speeds and double the range.<\/p>\n

<\/p>\n

At present most WiFi<\/a> routers come equipped with MIMO<\/strong> (Multiple-Input and Multiple-Output) or a variation of the same radio communications technology, which harnesses multiple antennas and signal paths at both the source and the receiving destination in order to deliver faster speeds. This also helps to combat interference, which improves reliability and performance.<\/p>\n

Related MIMO routers transmit their signals simultaneously from different antennae and each signal must also be transmitted via a spatial stream within the given spectral channel, which helps to avoid collisions that would damage performance. Most routers adopt a Single User (SU) approach to MIMO.<\/p>\n

The latest routers can also harness MU-MIMO<\/strong> (Multi-User) technology, which is capable of multitasking by sending data to multiple devices at once rather than one-at-a-time, which once again improves the overall network efficiency and throughput. However in recent years network congestion has become an increasing problem.<\/p>\n

The proposed MegaMIMO 2.0<\/strong> technology takes MU-MIMO a step further by coordinating multiple access points at the same time and also on the same frequency. Suffice to say, the ability to transfer data on the same chunk of spectrum and all without creating major interference is a huge development.<\/p>\n

All of this is achieved via a new technique for coordinating multiple transmitters by synchronizing their phases. Special signal-processing algorithms then allow multiple independent transmitters to transmit data on the same piece of spectrum to multiple independent receivers, without interfering with each other.<\/p>\n
