Types of TVBDs
* A Mode I TVBD isPower Spectral Density (PSD) Limits
The maximum power transmitted in any 100 kHz segment of spectrum is subject to the following limitations * Fixed devices: 12.2 dBm * Personal/portable devices: 2.2 dBm * Sensing-only device -0.8 dBm * Personal/portable devices operating adjacent to a nearby television channel: -1.8 dBmTransmit Power Control
All TVBDs must incorporate a feature to reduce transmitted power to the minimum level necessary to maintain successful communication.Antenna Height Restriction
The transmit antenna used with fixed devices may not be more than 30 meters above the ground. Fixed devices may not be located at sites where the height above average terrain (HAAT) is greater than 76 meters. Bandplans
