Impact of published worldwide uwb emission limits

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

Implications for uwb technologies
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.
