loss by adding an appropriate length of coax to reduce the maximum radiated power to within legal limits In 1, we summarized the FCC rules and made some rough comparisons to power levels and antenna gain In Tables 51 and 52, we present a more practical cross-reference to follow when applying different power amplifiers to different antennas in different wireless configurations

It is highly unlikely that anyone will ever know or report that you are running your wireless system in excess of the legal limits, but remember that if your wireless system causes interference to other devices, you are putting your operation at risk You also have to be careful where you place your antenna if you are going to run full power Tucking it into a flower box behind a frequently used bench on your patio will likely overexpose anyone who sits there to dangerous levels of RF It is also unlikely that you have handy the proper test equipment to measure the power output of your wireless devices to know whether or not you are in compliance with the power limits The most practical and accepted way to ensure that your system is within legal limits is to keep track of the power levels, gains, and losses of your system components in decibels, then add or subtract accordingly, to arrive at a calculated RF radiation level Point-to-multipoint configurations For point-to-multipoint setups (access point to clients), you are allowed up to 30 dBm or 1 W of transmitter power output (TPO) feeding into a 6 dBi antenna, 36 dBm total, equal to 4 W of effective isotropic radiated power (EIRP) (above the reference level of an isotropic antenna) The TPO needs to be reduced 1 dB for every dB of antenna gain over the baseline 6 dBi antenna gain In this system, it is fairly easy to work back from that 36 dBm maximum output level, substituting power output levels, antenna gain, and feedline loss values, to determine if your system output is above or below the legal limits Table 51 shows typical RF output levels versus antenna gain to achieve, but not exceed, the maximum output level

You will probably discover that the antennas you can buy do not have exactly 6, 9, 12, 16, or other integer-level gains 57 dBi, 82 dBi, 137 dBi, etc, may be more common but it is easier to round up, to be on the safe side To your advantage, as a margin of error, you can add 1 dB of loss for each connector in the path between wireless device and antenna So in the case of a wireless device plus amplifier plus antenna, there are at least four connectors in the line (one at the wireless device, one at the input to the amplifier, one at the output of the amplifier, and one at the antenna), giving you 2 dB of loss to the amplifier, which may reduce its output slightly, and 2 dB of loss from amplifier to antenna Connecting an antenna or amplifier to most wireless devices typically requires a pigtail or jumper wire to convert from an MC card or MMCX to a Type N connector for connection to a length of feedline Thus, you experience at least another 2 dB of loss for each of these connectors and the length of the jumper cable But this only affects the power level driving the amplifier, not the amplifier output, which may still be at the advertised level With all of this factored in, you could still use a 24 dBi gain antenna with a 250 mW amplifier With direct connections or no loss
