CHAPTER II. GENERAL CHARACTERISTICS

II.1. General Requirements

The M868-TinyPlus terminal is a multi channel radio modem, delivering up to 25 mW in the 868 MHz ISM band
(unlicensed frequency band).

It allows ‘point-to-point’, `multipoint’ or ‘mesh’ functioning modes.

The “ERC recommendation 70-03” describes the different usable sub-bands in the 868 MHz license free band, in
terms of bandwidth, maximum power, duty cycle and channel spacing. It gives the following limitations :

(%)

Annex1 g1 868.0 – 868.6 25 No channel spacing specified 1
Annex7 a 868.6 - 868.7 10 25 1
Annex1 g2 868.7 - 869.2 25 No channel spacing specified 0,1
Annex7 d 869.2 – 869.25 10 25 0.1
Annex7 b 869.25 – 869.3 10 25 0.1
Annex7 e 869.3 – 869.4 10 25 1
Annex1 g3 869.4 - 869.65 500 25 (for 1 or more channels) 10
Annex7 c 869.65 – 869.7 25 25 10
Annex1 g4 869.7 – 870.0 5 No channel spacing specified 100

This band is free to use but the terminal and the user must respect some limitations. Most of these restrictions are
integrated in the conception of the terminal, except the duty cycle. For example, the 869.400 to 869.650 MHz band
is limited to a 10% duty cycle. This means that each terminal is limited to a total transmit time of 6 minutes per
hour. It is the responsibility of the user to respect the duty cycle.

Furthermore, the terminal complies with the ETSI 300-220 (specific for SRD). The main requirements are described
in Appendix 1.

Finally, the terminal complies with the new European Directive 2002/95/EC concerning the Restrictive Usage of
Hazardous Substances (RoHS).
