I-inthanethi Yezinto engenabhethri ene-micro-powered transmitter

I-subset eyakhiwe abacwaningi baseNyuvesi yaseCalifornia, e-San Diego, e-USA, ivumela amadivayisi we-Inthanethi Yezinto (IoT) ukuthi axhumane namanethiwekhi e-Wi-Fi ngamandla aphindwe izikhathi eziyizinkulungwane ezinhlanu kunama-Wi-Fi amanje. Ngokwezilinganiso ezethulwe eNgqungqutheleni Yamazwe Ngamazwe Yesifunda Semiconductor Semiconductor ISSCC 2020 esanda kuphothulwa, idla kuphela ama-microwatts angu-28 (izigidi ze-watt).

Ngalawo mandla, ingadlulisela idatha ngamamegabhithi amabili ngomzuzwana (ishesha ngokwanele ukusakaza umculo namavidiyo amaningi e-YouTube) kufika kumamitha angu-21.

Imishini yesimanje ye-Wi-Fi ekwaziyo ukuhwebelana ngokuvamile isebenzisa amakhulukhulu ama-milliwatt (izinkulungwane zama-watt) ukuze ixhume amadivayisi e-IoT kuzithumeli ze-Wi-Fi. Ngenxa yalokho, isidingo samabhethri, amabhethri aphinde ashajwa, ukushajwa okuvamile noma eminye imithombo yamandla yangaphandle (bheka futhi:) Uhlobo olusha lwedivayisi likuvumela ukuthi uxhume amadivayisi ngaphandle kwamandla angaphandle, njengezitholi zentuthu, njll.

Imojula ye-Wi-Fi isebenza ngamandla amancane kakhulu, ithumela idatha kusetshenziswa indlela ebizwa nge-backscatter. Ilanda idatha ye-Wi-Fi isuka kudivayisi eseduze (efana ne-smartphone) noma indawo yokufinyelela (AP), iyilungise futhi iyibhale ngekhodi, bese iyidlulisela kwesinye isiteshi se-Wi-Fi iye kwenye idivayisi noma indawo yokufinyelela.

Lokhu kwafezwa ngokushumeka ingxenye ocingweni olubizwa ngokuthi isamukeli sokuvuka, "esivusa" inethiwekhi ye-Wi-Fi kuphela ngesikhathi sokudlulisa, futhi sonke isikhathi singahlala kumodi yokulala yokonga amandla sisebenzisa okuncane nje. 3 microwatts amandla.
