For frequency hopping systems, at least 75 hopping frequencies in a pseudorandom hopping pattern, separated by at least 25 kHz, shall be used, and the average time of occupancy on any frequency shall not be greater than four-tenths of one second within a 30 second period.  The maximum bandwidth of the hopping channel is at most 1 MHz.

• The FCC's Part15 Rules and Regulation and 802.11b emissions in the ISM 2.4GHz Band  By Tim Pozar
• Covered by the Code of Federal Regulations Title 47, parts 15.205, 15.209 and 15.247.
• The rest of the FCC rules.
• 2.3 - 2.4 GHz amateur radio bandplan and rules.
• Product's RF connectors must be hard to find. heh.
• +36 dBm (3.981 Watts) Effective Isotropic Radiated Power (EIRP) at external antenna for multipoint wireless links in the 2.4 GHz band.
• Operating band: 2.4 - 2.4835 GHz. (other bands are at: 902 - 928 MHz, 5725 - 5875 MHz, 10.5 - 10.55 GHz and 24.0 - 24.25 GHz)
• Maximum of +30 dBm (1 Watt) RF power output at the product's connector.  It's legal to have a 1000 watt (+60 dBm) amplifier, provided the coax has 30 dB of attenuation.
• Spurious emissions through 2.390 - 2.4835 GHz must be lower than -41 dBm. (0.000079433 milliwatts)
• All spurious emissions outside 22 MHz of the center carrier must be lower than 50 dB relative to the center frequency.
• Systems operating in the 2400-2483.5 MHz band that are used exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain greater than 6 dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi.  Example:
