Output power
*1 Provided the maximum antenna gain does not exceed 6 dBi. In addition, the maximum power spectral density shall not exceed 17 dBm in any 1 megahertz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount of dB that the directional gain of the antenna exceeds 6 dBi.
*2 Equivalent Isotropically Radiated Power (EIRP) is terminology for the total RF power radiated by the antenna.
*3 The maximum power spectral density shall not exceed 17 dBm in any 1 megahertz band. Fixed pointtopoint UNII devices may employ antennas with directional gain up to 23 dBi without any corresponding reduction in the maximum conducted output power or maximum power spectral density. For fixed pointtopoint transmitters that employ a diretional antenna gain greater than 23 dBi, a 1 dB reduction in maximum conducted output power spectral density is required for each 1 dB of antenna gain in excess of 23 dBi. Fixed, pointtopoint operations exclude the use of pointtomultipoint systems, omnidirectional applications, and multiple collocated transmitters transmitting the same information. The operator of the UNII device, or if the equipment is professionally installed, the installer, is responsible for ensuring that systems employing high gain directional antennas are used exclusively for fixed, pointtopoint operations.
*4 Provided the maximum antenna gain does not exceed 6 dBi. In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.
*5 In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.
*6 In addition, the maximum power spectral density shall not exceed 30 dBm in any 500kHz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. However, fixed pointtopoint UNII devices operating in this band may employ transmitting antennas with directional gain greater than 6 dBi without any use of corresponding reduction in transmitter conducted power. Fixed pointtopoint operations exclude the use of pointtomultipoint sytems, omnidirectional applications, and multiple collocated transmitters transmitting the same information. The operator of the UNII device, or if the equipment is professionally installed, the installer, is responsible for ensuring that systems employing high gain directional antennas are used exclusively for fixed pointtopoint operations.
