That feeling of need to smash your smartphone while get in touch to an over - crowded and impossibly sluggish public wi - fi mesh might soon be gone as researchers at MIT have come up with away to encourage wireless connection speedsby cleverly coordinating multiple routers .
The new technology , develop at MIT ’s Computer Science and Artificial Intelligence Lab ( CSAIL ) , has been dub MegaMIMO 2.0 and will not only make wi - fi speeds about three time quicker , it will also effectively double over its compass .
Based on the MIMO technology that ’s already used in wireless router . For those unfamiliar , the applied science work by sending multiple data signals over the same radio communication channel to increase transmission focal ratio . MegaMIMO 2.0 cleverly coordinate multiple access points , all circularize on the same limited oftenness and spectrum , to supercharge speeds and signal strength without degrading the signal .
So why ca n’t you already just put in two or three wireless routers in your place to boost your wi - fi speeds ? Multiple access point all broadcasting on the same relative frequency will terminate up create interference , making it hard for a gadget to decrypt the data stream . It ’s like when two radio stations are propagate on the same frequency while you ’re driving between two cities , the signaling gets through , but it ’s a garbled deal .
The find the MIT CSAIL squad arrive up with was new signal - processing algorithms that let multiple access decimal point and sender to synchronize their phases to eliminate interference . With multiple wireless routers all pass around at the same time , more data point current can be simultaneously broadcasted than stock MIMO techniques allow . Just guess of how much fast a filing cabinet being torrented can be downloaded when there are more sources available , and you ’ll have a adept musical theme of why this new technique can speed up wi - fi .
The researchers have already demonstrated MegaMIMO 2.0 influence on up to four accession points at the same metre , but they ’re convinced the new approaching could be effectively used on dozens of wireless routers at the same clip . But eventually it could also stand for that installing multiple access code item at home would do more than just kill wi - fi dead spots in your family .
