To: WayCool, 你说“FCC就允许100mw的发射功率”，究竟你有没有看过FCC part 15? 九叔2012-05-07 18:00:43

• Frequencies include 902-928 MHz, 2400-2483.5 and 5725-5850 MHz
• Maximum Transmitter Power Output (TPO) is 1.0 watt or 30dBm
• The formula for converting antennas from dBi to dBd is dBi-2.2=dBd

There are two different classifications for operation.
Point to Point (PTP) and Point to Multipoint (PTMP):

PTP: is when two sites talk only to eachother.
PTMP: is when multiple sites talk to a single core site.

Each of these modes have different EIRP (Effective Isotropic Radiated Power) limitations.

Point to MultiPoint (PTMP) Limitation:

• The maximum EIRP power allowed is 36dBm (4 watts).
