5 GHz WAS/RLAN - Harmonised Standard for access to radio spectrum

The present document specifies technical characteristics and methods of measurement for Wireless Access Systems
(WAS) including Radio Local Area Network (RLAN) equipment operating in the 5 GHz RLAN band.
The present document specifies spectrum access requirements to facilitate spectrum sharing with other equipment.
Radio equipment capable of operating in all or parts of the service frequency bands given in table 1 is within the scope
of the present document.
Provisions for radio equipment capable of operating in all or parts of the 5 725 MHz to 5 850 MHz frequency band
(sub-band 4 as given in table B.1) are contained in annex B. However, operation in sub-band 4 is subject to national
frequency usage conditions. The present document also contains provisions for equipment operating on channels whose
nominal channel bandwidth falls partly in sub-band 3 and partly in sub-band 4.
NOTE 1: The technical requirements for equipment operating in the service frequency bands identified in table 1
are contained in the main part of the present document (see clause 4) while the technical requirements for
equipment operating in the service frequency band identified in table B.1 are contained in annex B.
NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
