Note : The CCA time used by the equipment shall be declared by the supplier.
Note 2 : Load Based Equipment may implement an LBT based spectrum sharing mechanism based
on the Clear Channel Assessment (CCA) mode using energy detect, as described in IEEE
802.11™-2012 [i.3] clause 9, clause 10, clause 16, clause 17, clause 19 and clause 20, or in IEEE
802.15.4™-2011 [i.4], clause 4, clause 5 and clause 8.
Note 3 : Adaptive equipment may or may not have Short Control Signaling Transmissions.
Interference threshold level:
Maximum transmit power (P
Note 1 : TL = -70 dBm/MHz + 10 × log10 (100 mW / Pout)
Note 2 : transmitter the CCA threshold level (TL) shall be equal or lower than -70 dBm/MHz at
the input to the receiver (assuming a 0 dBi receive antenna).
