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 in sub-band b).
| Frequency Band | Power / Magnetic Field | Spectrum access and mitigation requirements | Modulation /occupied bandwidth | ECC/ERC Deliverable | Notes | |
|---|---|---|---|---|---|---|
| a | 868.6MHz - 868.7MHz |
10 mW e.r.p. | ≤ 1.0 % duty cycle | ≤ 25 kHz | The whole frequency band may also be used as a single channel | |
| b | 869.2MHz - 869.25MHz |
10 mW e.r.p. | ≤ 0.1 % duty cycle | channel spacing = 25 kHz | Social Alarms | |
| c | 869.25MHz - 869.3MHz |
10 mW e.r.p. | ≤ 0.1 % duty cycle | ≤ 25 kHz | ||
| d | 869.3MHz - 869.4MHz |
10 mW e.r.p. | ≤ 1.0 % duty cycle | ≤ 25 kHz | ||
| e | 869.65MHz - 869.7MHz |
25 mW e.r.p. | ≤ 10 % duty cycle | ≤ 25 kHz | ||
