  1. UWB Spectrum Allocations Date: 2008-05-13 Authors: John Notor, Cadence Design Systems, Inc.

  2. The original vision: 3.1 to 10.6 GHz Residue: 7.2 to 8.5 GHz WiMedia Band Group 1 WLAN: 4.9 to 6 GHz (incumbent business interests protected) 3.4 GHz Broadband Wireless (future licensed spectrum) Impact of Published Worldwide UWB Emission Limits John Notor, Cadence Design Systems, Inc.

  3. Implications for UWB Technologies • No worldwide coordinated spectrum for the following standards: • WiMedia v1.1 – Frequency Hopping OFDM • Bluetooth 3.0 – High Rate PHY Based on WiMedia v1.2 at > 6 GHz. • IEEE 802.15.4a – Includes a Pulsed UWB PHY • No common set of worldwide certification test requirements. • WiMedia v1.1 Band Group 1 (3168 to 4752 MHz) specifically hobbled in many countries. • Band Group 1 is mandatory in WiMedia v1.1. • Most early silicon supported only Band Group 1. • Detect and Avoid (DAA) may permit Band Group 1 operation in Europe and Japan, but DAA requirements as yet undefined.
