1. Introduction
1.1. Scope
Scope of this document is to present the features and the application of the Telit ME70-169
radio modules (ME70-169).
1.2. ME70-169 Product Description
The ME70-169 module is a multi-channel radio board, delivering up to 1W in the 169 MHz
ISM band (unlicensed frequency band). The module is provided with a UART interface for
serial communication and –configuration and one RF output pin.
It is delivered with preloaded protocol stack:
•ME70-169: “Wireless M-Bus Part 4 Mode N” Protocol stack.
ME70-169 is fully compatible with low power version ME50-169.
ME70-169 is pin-to-pin compatible with LE, NE and ME modules working at different
frequencies. ME70-169 is also pin-to-pin compatible with Telit ZE Family (ZigBee PRO
stack).

2. 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 radiated power
(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.
National Restrictions for non specific SR devices Annex 2 band B:
Country Restriction Reason/Remark
Band F
Austria Not implemented Planned
Belgium No info
Bulgaria Not implemented The band is used for national security needs
Croatia Limited implementation Individual licence required
Cyprus Cyprus has implemented Decision 2005/928/EC
