Txij thaum pib lub xov tooj ntawm tes mus rau hnub no' cov xov tooj ntse, xov tooj ntawm tes tau tsim los ntawm 2G thiab 3G mus rau 4G era, thiab yuav sai sai no tsim thiab tsim cov xov tooj ntawm tes hauv 5g era.
Tam sim no cov tuam txhab tsim xov tooj ntawm tes yuav txhim kho lawv lub xov tooj ntawm tes ntawm lub teeb thiab nyias, thiab lawv cov khoom siv sab hauv tau dhau los ua qhov me dua thiab me dua, nrog qhov tseeb ntau dua thiab kev siv hluav taws xob sib koom ua ke, thiab xav tau ntau dua rau cov khoom siv sab hauv.
Rau cov khoom me me hauv xov tooj ntawm tes, kev siv vuam zoo ntawm cov cuab yeej siv vuam tsis ruaj khov, uas yog ib qho yooj yim ua rau cov khoom yaj, tsis yooj yim rau tsim ib qho nugget, thiab cov khoom siv vuam tsawg. Qhov tshwm sim ntawm laser vuam tshuab tau daws cov teeb meem no rau cov khoom lag luam hluav taws xob.
Laser nqaj ua rau tsis ua kev sib cuag, nrog rau cov cua sov me me, thaj chaw ua haujlwm me me thiab hloov pauv tau. Hauv cov txheej txheem tsim khoom tam sim no ntawm cov xov tooj ntawm tes high-end, laser vuam siv lub tshuab thev naus laus zis ua lub luag haujlwm tseem ceeb hauv cov khoom ntim khoom kom zoo dua qub thiab txhim kho kom zoo dua qub, ua rau cov khoom sib zog, nyias thiab ruaj khov dua.
