Kev Tsav Tiv Thaiv Kev Tiv Thaiv rau Xov Xwm
Wireless chaw nres tsheb wireless yog ib qho ntawm cov neeg raug ntau tshaj plaws ntawm kev sib tw. Cov hlau pej thuam nyiam xob laim thiab cov khoom siv nyob rau hauv cov pej thuam thiab hauv chav siv tshuab kuj ntxig rau cov teebmeem loj dua lwm yam. Ntau theem fais fab kev pab tiv thaiv kom tsis txhob raug hluav taws xob. Txhua tus koom ua haujlwm cab thiab fibre-optical fibers yuav tsum muaj cov SPD.
