  1. IEEE 802.11a & IEEE 802.11nchanges for TGah Authors: Date: 2010-12-20 Jae-Hyung Song, LG Electronics

  2. Abstract Leverage a widely successful standard in available bands. Re-band OFDM and MIMO operation to TGah bands and provide for narrower channels with eight clocking. Keep IEEE 802.11 WLAN user experience through common IEEE 802.11 MAC. Jae-Hyung Song, LG Electronics

  3. Re-banding and narrower channel efforts • IEEE 802.11j-2004 • 4.9 GHz – 5 GHz Operation in Japan • Introduced “half-clocked” operation using 10 MHz channel spacing • IEEE 802.11-2007 • Introduced “quarter-clocked” operation using 5MHz channel spacing • IEEE 802.11y-2008 • 3650 – 3700 MHz Operation in USA • P802.11af D0.06 • Re-band OFDM and MIMO including 5 & 10 MHz channel spacing Jae-Hyung Song, LG Electronics

  4. Solutions are available today with up/down converter added to existing silicon. Future optimized solutions possible for better power consumption and lower cost. Leverage existing efforts Jae-Hyung Song, LG Electronics

  5. Increase reliability and system performance with some of the optional IEEE 802.11n functionality • Space-time block coding (STBC) • Beamforming • Low-density parity check codes (LDPC) • Aggregation • A-MPDU • A-MPDU aggregation of broadcast traffic • A-MDSU IEEE 802.11n brings more than MIMO Jae-Hyung Song, LG Electronics
