DRAFT OF USER MANUAL SUPPLEMENT FOR US & CANADA

The EIRP relaxation for point-to-point operation applies at 2.4 GHz (3:1 rule) and 5.8 GHz (no EIRP limit, i.e.

unlimited antenna gain). At 2.4 GHz, the 3:1 rule is defined as follows. For every 3 dB of antenna gain

exceeding 6 dBi, power delivered to the antenna must be reduced 1 dB below the otherwise permitted maximum

transmitter peak output power of 1 watt (30 dBm or 0 dBW). The power level delivered to the antenna at

2.4 GHz (S-band) in point-to-point operation can be calculated as the lessor of:

Power delivered to antenna = Lesser value in Table 1 or Table 2

30 dBm - (Gain Antenna - 6dBi)

NOTE:

Exceeding specified levels may create an installation that violates FCC Rules and

Regulations or Canadian IC requirements
