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

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 a – 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.
