2. Regulatory Conformance Information

2.1. Operational Frequency Bands

The module radio transmitter operations must be compliant with some regulatory requirements in terms of frequency bands and emitted power, as detailed below.

2.1.1. 915 MHz Band Requirements

The FCC part 15.247 regulates the frequency hopping RF devices, and gives the following requirements:

Frequency Band Channel spacing Maximum

radiated power

25< “20dB BW” < 250kHz 1W

902-928 MHz

250 < “20dB BW” < 500kHz 250mW

Hopping cycle

<0.4s each

20s<0.4s each

20s,

50 hop. Freq

min

<0.4s each

10s,

25 hop. Freq.

min

The main requirements of the FCC regulation are given in [1]. The xE70-915 module operates in the ISM band. This band is 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.

2.2. Other Regulatory Requirements

The module complies with the European Directive 2002/95/EC concerning the Restrictive Usage of Hazardous Substances (RoHS).
