802.11 a/b/g/n

  Refers to a wireless network protocol standard, are derived from the evolution of 802.11.

    IEEE 802.11 is originally designated a wireless LAN standard, the rate can only reach 2Mbps

    802.11b operate in 2.4G frequency band, the maximum rate of 11M, will be phased out, RF dynamic rate conversion when the condition is deteriorated, the data transfer rate can be reduced to 5.5.Mb / s, 2Mb / s and 1Mb / s

    802.11a band works in 5.4G, 54M highest frequency, it is mainly used in long-distance wireless connection

    802.11g work at 2.4G band, the highest rate of 54M

    802.11n is a technology developed over 802.11g and 802.11a, the biggest feature is the rate doctors, v theoretical match up to 600Mbps (the industry mainstream 300Mbps) .802.11n can operate in both 2.4GHz and 5GHz bands

    802.11ac is established on WiFi 802.11a wireless standards, including the use of the 5GHz band 802.11a. Transfer rate up to 1Gbps. 802.11ac theoretical maximum achievable 7Gbps
