AT&T Pow­ers Up Air­gig

Sound & Vision - - APPTITUDE -

AT&T’S Air­gig delivers 1-gi­ga­bit-per­sec­ond in­ter­net ser­vice us­ing a novel pow­er­line-as­sisted tech­nol­ogy. Sig­nals don’t travel through the power grid di­rectly. In­stead, mil­lime­ter wave sig­nals are guided by an­ten­nas con­nected to the grid by lo­cal elec­tri­cal work­ers. The tech­nol­ogy is de­signed to bring in­ter­net ser­vice to ur­ban, ru­ral, and un­der­served ar­eas in gen­eral, in the U.S. and world­wide. The first test is in a ru­ral part of Ge­or­gia in part­ner­ship with a lo­cal util­ity, the Ge­or­gia Power-south­ern Com­pany. In ad­di­tion to feed­ing mo­bile de­vices, AT&T also thinks the tech­nol­ogy has ap­pli­ca­tions in aug­mented re­al­ity and self-driv­ing cars. (In­ci­den­tally, ac­cord­ing to Wikipedia, the dis­tinc­tion be­tween aug­mented re­al­ity and vir­tual re­al­ity is that “aug­mented re­al­ity en­hances one’s cur­rent per­cep­tion of re­al­ity, whereas vir­tual re­al­ity re­places the real world with a sim­u­lated one.”)— MF
