While there has been a lot of activity across the world in opening up the 6 GHz band for Wi-Fi, work is still being done on the legacy 5 GHz Wi-Fi band. The FCC has voted in favor of new 5.9 GHz (i.e., 5.850 GHz to 5.925 GHz) rules, allowing Wi-Fi in most parts of the United States to utilize the low 45 MHz for Wi-Fi, offering new, license-free channels—including one 160 MHz channel, at the top of the 5 GHz range—and expanding the overall 5 GHz band. The FCC has stated that this part of the band, while limited in size, is in an important position, adjacent to the existing unlicensed 5 GHz Wi-Fi spectrum.
