modulated data bits?
IEEE 802.11n
IEEE 802.11g
IEEE 802.11ac
IEEE 802.11s
IEEE 802.11w
5 GHz frequency following the standards of UNII (Unlicensed National Information Infrastructure). frequency division multiplexing (FDM) standard. Able to transfer data up to 54 Mbps
802.11a
802.11b
802.11g
802.11b/g/n
802.11ac
Offers maximum throughput of 11 Mbps (6 Mbps in practice) and range of up to 300 meters in open environments. It uses a frequency range of 2.4 GHz, with 3 radio channels available. Data transmission 5.4 to 11 Mbps
802.11a
802.11b
802.11g
802.11b/g/n
802.11ac
offers bandwidth with a maximum capacity speed of 1000 Mbps or 1 Gbps and the maximum speed per user (such as laptops and other client devices) is 500 Mbps, which is achieved by developing a wide bandwidth, which is 160 Mhz, coupled with MIMO support and of course with a high modulation density
