Entry-level 5G WiFi products will be 450 megabits per second, which is at least three times faster than the most common devices using the current wireless system, 802.11n. And because the new standard gives manufacturers the flexibility to offer a range of products with different levels of performance, some high-speed 802.11ac devices will offer transmission in excess of a gigabit per second -- remarkable speeds that wired networks attained only recently.
5G Wifi offers dramatic improvements in wireless reliability, range and coverage. Homes and apartments now plagued with "dead spots" will enjoy vastly improved reception. But because 802.11ac transmissions start out so much faster than those from earlier networks, you can be, say, 30 feet away from an 802.11ac access point and get the same data throughput that you would if you were 10 feet from an 802.11n transmitter. But 5G Wifi networks, with beam-forming and other innovations, do a much better job in penetrating all forms of building materials, including concrete than its predecessors.
Because 802.11ac transfers files so much more quickly, it will be up to six times more power-efficient that the wireless chips found in phones today. Mobile phone users will thus be able to go longer between battery rechargings than they would if transferring equivalent amounts of data using today's Wi-Fi networks.
