  1. 802.11ah Channelization Proposal for US Authors: Date: 2011-11-07 Huai-Rong Shao, et.al. Samsung Electronics

  2. In this document we propose a revised transmission channelization in US for 802.11ah • Suggest twenty-six 1 MHz channels instead thirteen 1 MHz channels • The lower 1MHz of each 2 MHz channel as primary 1MHz channel • The higher 1MHz of each 2 MHz channel as secondary 1MHz channel • The secondary 1MHz channel cannot be used unless none of the primary 1 MHz channels is available Abstract Huai-Rong Shao, et. al, Samsung Electronics

  3. From 2011-11-1329r1/1296-r3 (Rolf de Vegt, Qualcomm) US Channelization (902 – 928MHz) 902MHz 928MHz 1 MHz 2 MHz 4 MHz 8 MHz 16 MHz Note:Devices operating in the 1 MHz PHY mode are expected to operate in the lower 1 MHz of each 2 MHz wide channel Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. Huai-Rong Shao, et.al, Samsung Electronics

  4. Issues Un-resolved from Sept. 2011 meeting • Thirteen 1 MHz channels or twenty-six 1 MHz channels for 802.11ah in US? • Thirteen channels may be enough but we never know what will be for future applications • Straw poll result: • Yes: 24, • No 17, • Abstain 17 • Straw poll result: • YES: 31 • No: 11 • Abstain: 15 Samsung Electronics

  5. Revised proposal: US Channelization (902 – 928MHz) • Note:The lower 1MHz of each 2 MHz channel as primary 1MHz channel and the higher 1MHz of each 2 MHz channel as secondary 1MHz channel • The secondary 1MHz channel cannot be used unless none of primary 1 MHz channels is available • Devices operating in the 1 MHz PHY mode shall support primary 1MHz channels and may support secondary 1MHz channels • Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. • Coexistence rules between 2 MHz PHY mode and 1 MHz PHY mode TBD. Huai-Rong Shao, et.al. Samsung Electronics

  6. Do you agree with the following channelization for the US: Yes, No, Abstain Straw poll: Channelization for US Huai-Rong Shao, et.al, Samsung Electronics • Note:The lower 1MHz of each 2 MHz channel as primary 1MHz channel and the higher 1MHz of each 2 MHz channel as secondary 1MHz channel • The secondary 1MHz channel cannot be used unless none of primary 1 MHz channels is available • Devices operating in the 1 MHz PHY mode shall support primary 1MHz channels and may support secondary 1MHz channels • Channels >= 4 MHz are right aligned to prevent interference on the 1 and 2 MHz channels at the lower edge of spectrum. • Coexistence rules between 2 MHz PHY mode and 1 MHz PHY mode TBD.

  7. Thank You! Huai-Rong Shao, et.al, Samsung Electronics
