The operating frequency must be selected in such a way that the complete modulated signal
stays within the band of 902 - 928MHz. The modules can be operated at any frequency
between the lowest and highest frequencies in the band. The lowest and highest frequencies
are given as follow:
Lowest Frequency: 902.7MHz
Highest Frequency: 927.377MHz
2.5.2. Europe
Table 4
ETSI Approved configurations
shows the approved configurations for use in Europe. All
configurations are optimized for the best sensitivity. In order to meet different customer needs, a
variety of datarates from 600 Baud to 600 kBaud has been provided.

Within the European 868-870 MHz ISM band, there are several sub-bands with different
requirements. A summary of these bands is given in Table 5. Considering the modulation
bandwidth of each modulation type, frequency drift of the module in the extreme working
conditions, and the channel spacing for each configuration, usable channels for each
modulation is obtained for the sub-bands. Table 6 lists the approved configurations and
applicable channels for each sub-band. Table 7 shows list of available channels along with the
corresponding frequencies and register settings.
