This morning Broadcom announced 5G: "Broadcom Extends 5G WiFi Leadership with New 802.11ac Chips." This is kind of funny because most folks are confused by 3G versus 4G. Many think that iPhones run on 4G, but actually they all run on the 3G networks. No radio in there yet to pick up 4G.
Despite all the ads from the Big 4 cellcos about 4G, "Large portions of the western half of the U.S. do not have access to 3G or faster mobile broadband service, according to a new map released by the U.S. Federal Communications Commission," according to a PCWorld article.
