  1. Requirements for AlternateChannelization in TGj Sheung Li, Atheros Sheung Li, Atheros

  2. Channel Allocation 20 MHz Example Center Channels: 20MHz System: 4920MHz, 4940MHz, 4960MHz, 4980MHz, 5040MHz, 5060MHz, 5080MHz 10MHz System: 4915MHz, 4920MHz, 4925MHz, 4935MHz, 4940MHz, 4945MHz, 5035MHz, 5040MHz, 5045MHz, 5055MHz 5MHz System: 4912.5MHz, 4917.5Hz, 4922.5MHz, 4927.5MHz, 4932.5MHz, 4937.5MHz, 4942.5MHz, 4947.5MHz, 5032.5MHz, 5037.5MHz, 5042.5MHz, 5047.5MHz, 5052.5MHz, 5057.5MHz Sheung Li, Atheros

  3. Transmit Mask Issues (Inband) 20 MHz Example Inband (STA) Inband (AP) Sheung Li, Atheros

  4. Transmit Mask Issues (OOB) Sheung Li, Atheros

  5. Spurious Leakage Sheung Li, Atheros

  6. System Sharing Sheung Li, Atheros

  7. Receive Sensitivity • Same as 802.11a for 20 MHz channelization • Same for 10 MHz and 5 MHz channelizations of same protocol • Doubling timing by halving or quartering clock increases by 3 dB • Halving or quartering carrier widths decreases by 3 dB Sheung Li, Atheros

  8. Blocker Performance • Lesson from ASTM E17.51 Proceedings • Different indoor and outdoor applications have different requirements • Tx Pwr from 1mW to 250mW or more • Tx Distance from 1m to 500m or more • Physical Separation varies from co-located arrays to many km’s. • Recommend provide for different levels of relative adjacent/alternate channel rejection from current • Type 1: -6dB, Type 2: -3dB • Type 3: +0dB • Type 4: +3dB, Type 5: + 6dB Sheung Li, Atheros

  9. Timing Differences Sheung Li, Atheros

  10. Differences By Channelization Sheung Li, Atheros
