  1. IEEE802.11ac Upcoming new Wi-Fi technologies

  2. Speed competition IEEE802.11n Wi-Fi LTE ( Long Term Evolution )

  3. IEEE 802.11 n 600 Mbps IEEE 802.11 ac 600Mbps

  4. Three factors for increasing speed 1. Bandwidth 2. MIMO Stream 3. QAM

  5. Three factors Bandwidth Note 1. There are 108 sub-carriers in 40MHz and 468 sub-carriers in 160MHz,so, 468/108 = 4.35

  6. MIMO Innovative technology

  7. Stream support Main device: only support 3 streams Standard PCs: only support up to 2 streams Smartphones: only support 1 stream

  8. Three factors MIMO Stream If there is a device that supports 2 streams, up to 4 devices can be used at the same time with one AP.

  9. Three factors QAM Note 2. 256QAM is 8bit per symbol, 64QAM is 6bit per symbol, so, 8/6 = 1.33

  10. Power saving technology of devices has been improved

  11. Power saving technology Existing technology New technology

  12. Standardization IEEE and Wi-Fi Alliance (WFA)

  13. Wider bandwidth

  14. Advantage of IEEE802.11ac Boast a 6.9Gbps maximum transmission speed 2. Support MU-MIMO 3. Improved power saving

  15. Thank You
