  1. Co-existence with IEEE 802.16a Mika Kasslin, Nokia

  2. IEEE 802.16a • Medium Access Control Modifications and Additional Physical Layer Specifications for 2-11 GHz • The resulting standard specifies the air interface of fixed (stationary) broadband wireless access systems providing multiple services • Targeted frequency bands include 5.25-5.35 GHz and 5.725-5.825 GHz • The intention is to send the draft to sponsor ballot from this meeting Mika Kasslin, Nokia

  3. 5 GHz co-existence • 256-FFT OFDM mandatory • 2048-FFT OFDMA optional • TDD only • 10 MHz and 20 MHz channelization mandatory, 5 MHz optional • with 20 MHz channelization center carriers: 5280, 5300, 5320, 5745, 5765, 5785, 5805 MHz Mika Kasslin, Nokia

  4. 5 GHz co-existence • The standard shall include Dynamic Frequency Selection (DFS) • provides capabilities to assess channel quality and communicate that information • facilitates co-existence • addresses issues covered by 802.11 TGh • Active transmit power control (TPC) mechanism to facilitate band sharing Mika Kasslin, Nokia
