Calculated Distances And Power Compliance Margins; Table 3 - Power Compliance Margins - Motorola PTP 600 Series User Manual

Peak power density in the far field of a radio frequency point source is calculated as follows:

Calculated Distances and Power Compliance Margins

Table 3 shows calculated minimum separation distances d, recommended distances and
resulting power compliance margins for each frequency band and antenna combination.

Notes:
1. The regulations cover the power averaged over a 6 minute period.
2. At 5.4GHz the product is generally to a fixed EIRP which can be achieved with the
Integrated Antenna. If there are no EIRP limits, use the distance calculations for 5.8GHz.
3. At 5.8GHz, for antennas between 2ft and 6ft, alter the distance proportionally to the
antenna gain.
