ANNEX 7: ALARMS

Scope of annex
This annex covers frequency bands and regulatory as well as informative parameters recommended exclusively for alarm systems including social alarms and alarms for security and safety. The sub-bands below are intended for the following applications: Alarms in sub-bands a), c), d), e); Social Alarms sub-band b).

Frequency Band Power / Magnetic Field Spectrum access and mitigation requirements Modulation / maximum occupied bandwidth ECC/ERC Deliverable Notes
