If the equipment does not have a connector, a reference antenna with 0 dBi gain is assumed.

Equipment with power control capability optimizes the output power in a link with LMP commands . It is done by measuring RSSI and report back if the power should be increased or decreased. Note that power class 1 must not be used for sending packets from one device to another if the receiving side of a connection does not support the necessary messaging for power control of the sending side (i.e. RSSI measurements and related messages).

data transmitted has a symbol rate of 1 Ms/s. The zero crossing error is the time difference between the ideal symbol period and the measured crossing time. This shall be less than ± 1/8 of a symbol period. 3.2 SPURIOUS EMISSIONS The spurious emission, in-band and out-of-band, is measured with a frequency hopping transmitter hopping on a single frequency; this means that the synthesizer must change frequency between receive slot and transmit slot, but always returns to the same transmit frequency.
PAGE 5
3.3 RADIO FREQUENCY TOLERANCE The transmitted initial center frequency accuracy must be ±75 kHz from Fc. The initial frequency accuracy is defined as being the frequency accuracy before any information is transmitted. Note that the frequency drift requirement is not included in the ±75 kHz. The transmitter center frequency drift in a packet is specified in Table 3.4. The different packets are defined in the Baseband Specification.

Federal Communications Commission (FCC) Statement 15.21 You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. 15.105(b) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
