Technical requirements

RF output power

The RF output power is defined as the mean equivalent isotropic radiated power (e.i.r.p.) of

the equipment during a transmission burst.

The max allowed limit is -10 dBW (20 dBm, 100 mW).

Power spectral density

It is the mean equivalent isotropically radiated power spectral density during a transmission

burst.

Its value is limited to 10 dBm per MHz.

Occupied channel bandwidth

It is the bandwidth that contains 99% of the power of the signal.

It shall fall completely within the band 2.4 GHz to 2.4835 GHz.

Transmitter unwanted emissions in the out-of-band domain

They are emissions when the equipment is in transmit mode, on frequencies immediately

outside the necessary bandwidth which results from the modulation process, but excluding

spurious.

The transmitter unwanted emissions in out-of-band domain but outside the allocated band,

shall not exceed the values provided by the mask in Table 1.

Transmitter unwanted emissions in the spurious domain

Transmitter unwanted emissions in spurious domain are emissions outside the allocated

band and outside the out-of-band domain (as specified in previous table), when the

equipment is in transmit mode.

The transmitter unwanted emissions in the spurious domain shall not exceed the values

given in Table 2:
