Internet isina bhatiri yeZvinhu ine micro-powered transmitter

26.05.2022 /

Chikamu chakagadzirwa nevatsvaguri vepaYunivhesiti yeCalifornia, San Diego, USA, inobvumira Internet Yezvinhu (IoT) zvishandiso kutaurirana neWi-Fi network nezviuru zvishanu zvakaderera simba pane ikozvino Wi-Fi transmitters. Zvinoenderana nezviyero zvakaunzwa kuMusangano wepasi rose weSemiconductor Circuits ISSCC 2020, inongoshandisa 28 microwatts (mamiriyoni ewatt).

Nesimba irori, inokwanisa kuendesa data pamamegabit maviri pasekondi (nekukurumidza zvakakwana kufambisa mimhanzi uye mazhinji eYouTube mavhidhiyo) kusvika kumamita makumi maviri nerimwe.

Zvishandiso zvemazuva ano zvekutengesa zveWi-Fi zvinowanzo shandisa mazana emamilliwatts (zviuru zvewatt) kubatanidza zvishandiso zveIoT kune maWi-Fi transmitters. Somugumisiro, kudiwa kwemabhatiri, mabhatiri ekugadzirisa, kutengesa nguva dzose kana mamwe magetsi ekunze (onawo :) Rudzi rutsva rwechigadziro runokubvumira kubatanidza zvishandiso pasina simba rekunze, zvakadai sezviputi zveutsi, nezvimwewo.

Iyo Wi-Fi module inoshanda nesimba shoma shoma, kutumira data uchishandisa nzira inonzi backscatter. Iyo inodhawunirodha data yeWi-Fi kubva kune iri padyo mudziyo (senge smartphone) kana nzvimbo yekupinda (AP), inoishandura uye nekuiisa encode, uye yozoiendesa kune imwe chiteshi cheWi-Fi kune chimwe chishandiso kana nzvimbo yekuwana.

Izvi zvakawanikwa nekumisikidza chikamu mumudziyo unonzi wake-up receiver, iyo "inomutsa" iyo Wi-Fi network chete panguva yekufambisa, uye imwe nguva inogona kuramba iri musimba rekuchengetedza kurara mode uchishandisa zvishoma se 3 microwatts simba.
