Maximum Antenna Gain
The OBR5000B is a low-powered license-exempt radiocommunication device. Therefore, the maximum antenna gain
permitted (for devices in the band 5725-5825 MHz) to comply with the e.i.r.p. limits specified for point-to-point and non
point-to-point operation as appropriate, as stated below:
• For the band 5725-5825 MHz, the maximum conducted output power shall not exceed 1.0 W or 17 + 10 log10 B,
dBm, whichever power is less. The power spectral density shall not exceed 17 dBm in any 1.0 MHz band. The
maximum e.i.r.p. shall not exceed 4.0 W or 23 + 10 log10 B, dBm, whichever power is less. B is the 99% emission
bandwidth in MHz.
• Fixed point-to-point systems for this band are permitted to have an e.i.r.p. greater than 4 W, provided that the higher
e.i.r.p. is achieved by employing higher gain antennas, but not higher transmitter output powers. Point-to-multipoint
systems, omni-directional applications and multiple co-located transmitters transmitting the same information are
prohibited from exceeding 4 W e.i.r.p. However, remote stations of point-to-multipoint systems shall be permitted to
operate at greater than 4 W e.i.r.p, under the same conditions as for point-to-point systems.
