Note 1: The Radio Regulations 2011 erroneously specify that the 5470 – 5725MHz band is for indoor use only on a licence exempt
base. The correct position for this band (also referred to as the Outdoor HIPERLAN band) is set out in the 2008 Frequency Licence
Exemption Regulations. The process leading to the finalisation of the Radio Regulations 2011 at no stage contemplated a change to
this band.

the highest level of desired power.

 Point-to-multipoint systems, omnidirectional applications and multiple colocated transmitters transmitting the same

Note 3.
 In any 100kHz outside the band, the eirp
shall be at least 30dB below the 100kHZ

level of desired power.
Note 2: The Radio Regulations 2011 do not completely incorporate the 5.8GHz Decision (December 2009). The process leading to the
finalisation of the Radio Regulations 2011 at no stage contemplated a change to this band. There is a different point of view that the correct
position is that the PtP limit is 4W as laid out in Annexure B to the Radio Regulations 2011.
Note 3: Transmission towards the common node of a point-to-multipoint system is regarded as point-to-point mode.

• Band is not currently available for

from the definition of SRD and has
practical effect in ICASA not type
approving equipment intended for
creating data links in this band.
