Extend the frequency band of the ETS 300 632 from 24.25 - 29.5 GHz to 24.25 - 31.8 GHz and modify equipment parameters if necessary. During this redrafting the opportunity will be taken to implement current TM4 practice and replace the ETS with an EN. For example, the section dealing with spurious emission, which currently defines limits, will be changed to reference CEPT Rec. 74-01. A section dealing with EMC will be added. Note. Currently the United Kingdom authorises the use of the frequency ranges from 31.0 to 31.3 GHz and 31.5 to 31.8 GHz for analogue security video systems using a Voluntary National Standard (VNS). The European Commission have authorised the use of the VNS but strongly recommended that the Radiocommunications Agency initiate work within TM4 to draft a European standard for 31 GHz analogue surveillance systems.
