instructs the radio to dwell on the specified channel for the specified amount of time. After taking
several samples the radio displays the signal level detected in that channel over time.
3.2.8 Output Power Limits (FCC)
The Federal Communications Commission (FCC) regulations limit the maximum Effective Isotropic
Radiated Power (EIRP) for spread spectrum systems operating in the 900 MHz or the 2.4 GHz band.
The tables below show the maximum allowed output power using the various antennas.

3.2.9 Output Power Limits (CE)
The European Telecommunications Standards Institute (ETSI) regulations impose a limit of 20 dBm
as the maximum Effective Isotropic Radiated Power (EIRP) for direct sequence spread spectrum
systems operating in the 2.4 GHz band. In addition the maximum spectral power density is limited to
10 dBm per MHz maximum EIRP. Of these two limits the power density is the most restrictive for
this radio. The installer must reduce the output power of the pulsAR radio so that the EIRP of the
radio does not exceed TBD dBm. The antenna gain, cable and connector losses must be taken into
account when computing the maximum output power.
3.2.10 Maximum Permissible Exposure (MPE) Limitations
The installer must mount all transmit antennas so as to comply with the limits for human exposure to
radio frequency (RF) fields per paragraph 1.1307 of the FCC Regulations . The FCC requirements
incorporate limits for Maximum Permissible Exposure (MPE) in terms of electric field strength,
magnetic field strength, and power density.
