Regulatory Conformance Information
The module radio transmitter operations must be compliant with some regulatory
requirements in terms of frequency bands and emitted power, as detailed below.
2.1.
169 MHz band Requirements
The “ERC recommendation 70-03 Annex 2” describes the 169 MHz license free band for
meter reading, in terms of bandwidth, maximum power, duty cycle and channel spacing. It
gives the following limitations:
ERC recommendation 70-03
Band
Frequency band
(MHz)
Maximum

(mW)
Channel spacing
(kHz)
Duty cycle
(%)
2b
169.4 – 169.475
500
Max 50 khz
10
These bands are free to use but the module and the user must respect some limitations. Most
of these restrictions are integrated in the conception of the module, except the duty cycle. For
example, the 2b band is limited to a 10% duty cycle. This means that each module is limited
to a total transmit time of 6 minutes per hour. It is the responsibility of the user to respect the
duty cycle.
