New Frequency Version of SATELLINE-3AS

European Telecommunications Standards Institute (ETSI) has released a new frequency band for narrow and broadband ISM-purposes (Industrial, Scientific, and Medical). The 868 ... 870 MHz band is divided into sub-bands according to transmit power (max 0.5W) and duty cycle allowed for the transmitter.

Satel’s newest version of 3AS uses the 869.4 ... 869.65 MHz frequency band. This band has 10 separate 25 kHz channels for a maximum power of 0.5 W ERP* and 10% of transmitters duty cycle. Transmitter duty cycle and the maximum constant transmission time (max 36 seconds) must be controlled by data terminal equipment. Other features of the modern SATELLINE 3AS version are equivalent with the older 450 MHz version.

Note! Propagation of radio signals at higher frequencies differs from the propagation at lower frequencies. The rule of thumb is that when you double the frequency you cut the communication distance in half. So compared to the 450 MHz version the maximum communication distance is half when SATELLINE 3AS 869 MHz version is used.
