In AB405 the conditions for these equations are as follow:
Antenna BW: 1Ghz (20% at 5Ghz) Frequency of operation: 5-
6Ghz. Transmit power: 100-300mW.
Placing these numbers into the above formulas derives the
minimum operation distance between Camera operator and
Antenna to be 1.3cm.
Operating instructions:
In order to operate AB405 safely, please follow these rules:
1. Do not touch the antennas while the
system is working
2. Do not open the system case.
3. Camera Operator should keep a 1 cm distance between
antenna and operator in 100mw power transmit mode,
1.3 cm in case of 200mw transmit power and 1.6 cm in
case of 300mw transmit power. This is based on
EN62479 Far/near filed calculation.
