For equipment with radiated power of less than 100 μW e.i.r.p., no access technique is required. There are two mechanisms to access the spectrum:
Receiver Category 2 or better should be used for all equipment using LBT or DAA.
Equipment utilizing LBT or DAA do not have to comply with the duty cycle conditions.
For spread spectrum systems, LBT may be used if the required timing and threshold limits can be met; if not, then a duty cycle requirement applies.
