4.4.1.2 Receiver LBT Threshold and Transmitter Max On-Time

The LBT threshold is defined as the received signal level above which the equipment can determine that the channel is not available for use. If the received signal is below the LBT threshold, then the equipment can determine that the channel is available for use.

The maximum LBT threshold limits for the receiver in listen mode are shown in Table 4-12. The limits for Tx max on-time is shown in Table 4-11.

Table 4-12 Limits for LBT Threshold Values Versus Transmit Power
Tx PowerLBT Threshold Limit (1), (2)Notes
< 100 mW-80 dBm + CC = 10*logBW, Where,
BW is the bandwidth in MHz.
500 mW-87 dBm + C
(1) The limit is independent of the receiver category, see Section 4.3.1.
(2) The limits are based on an antenna gain of +2 dBi maximum. For other antenna gains greater than +2 dBi the limits should be adjusted accordingly.
