13 September, 2016

With wireless products using 802.11ac now widely available, both individual consumers and businesses need to know about this wireless standard.

The main difference between 802.11ac and any previous wireless standard is just how fast this new standard is.

802.11ac (or 5G Wi-Fi) comes after 802.11n (or N/Wireless-N). Fortunately, the new standard is compatible with the old one, which means that N clients are supported by 5G Wi-Fi, and 5G Wi-Fi clients can connect to an N router. Wireless-N is also compatible with all other wireless standards, which includes 802.11a, 802.11b, and 802.11g.

That essentially means that a router can be replaced at home with a 5G router and current wireless devices, including an iPhone, iPad, and laptop, no matter how old they are, and they can connect to a network, in the same way they always have. However, for these devices to operate at 5G speed, 5G Wi-Fi needs to be supported by both the router and the clients.

802.11ac clients reportedly also provide much-improved battery life than N clients. This is largely a result of the faster speed. That 5G clients can transmit the same volume of data in approximately a third amount of the time, when compared with B clients, means that less energy is being consumed.
