2.3.3 Nominal Output Power Levels
The CM-42 is able to operate in several modes and different output power levels. Applications may require output
power levels similar to those in a handheld cellular phone or higher levels commonly required when in rural areas.
Table 3: Mobile Station Nominal Analog Power Levels below shows the nominal output power levels of the CM42.
(Effective Radiated Power, assuming a maximum antenna system gain of 1 dBi (2.5 dBi antenna gain with 1.5 dB
cable loss)).
