Intaneti ya Zinthu yopanda batire chifukwa cha transmitter yamagetsi yaying'ono

Kagawo kakang'ono kopangidwa ndi ofufuza a ku yunivesite ya California, San Diego, USA, imalola zida za Internet of Things (IoT) kuti zizilumikizana ndi ma netiweki a Wi-Fi pamagetsi ocheperako zikwi zisanu kuposa ma transmitters apano a Wi-Fi. Malinga ndi miyeso yoperekedwa ku Msonkhano Wapadziko Lonse wa Semiconductor Circuits ISSCC 2020 womwe wangomaliza kumene, umangodya ma microwatts 28 (millionths of a watt).

Ndi mphamvu imeneyo, imatha kusamutsa deta pa ma megabits awiri pamphindi imodzi (mwachangu mokwanira kukhamukira nyimbo ndi mavidiyo ambiri a YouTube) mpaka mamita 21 kutali.

Zipangizo zamakono zamakono za Wi-Fi nthawi zambiri zimagwiritsa ntchito ma milliwatts (zikwizikwi za watt) kulumikiza zida za IoT ku ma transmitters a Wi-Fi. Chotsatira chake, kufunikira kwa mabatire, mabatire owonjezera, kulipira kawirikawiri kapena magwero ena amphamvu akunja (onaninso :) Mtundu watsopano wa chipangizo umakulolani kugwirizanitsa zipangizo popanda mphamvu zakunja, monga zowunikira utsi, etc.

Module ya Wi-Fi imagwira ntchito ndi mphamvu zochepa kwambiri, kutumiza deta pogwiritsa ntchito njira yotchedwa backscatter. Imatsitsa deta ya Wi-Fi kuchokera ku chipangizo chapafupi (monga foni yamakono) kapena malo olowera (AP), imaisintha ndikuyiyika, kenako imatumiza kudzera pa njira ina ya Wi-Fi kupita ku chipangizo china kapena malo ofikira.

Izi zidatheka ndikuyika gawo mu chipangizocho chotchedwa wolandila kudzuka, chomwe "chimadzuka" maukonde a Wi-Fi panthawi yopatsirana, ndipo nthawi yotsalayo imatha kukhalabe munjira yopulumutsa mphamvu yogona pogwiritsa ntchito pang'ono. 3 ma microwatts amphamvu.
