More and more, the internet is delivered wirelessly, but as bandwidth demand grows in each home — multiple TVs, smart devices, tablets and phones — current Wi-Fi standards are starting to fall short. Fortunately the FCC and wireless industry are prepared for this, and the former has just officially proposed opening up a wide swathe of spectrum to bring our Wi-Fi systems up to gigabit level. Many of the devices we use now operate on what’s called “unlicensed” bands of spectrum, so called because they’re not set aside specifically and tightly regulated, like military or official broadcast bands.
