The SATELLINE-1915 uses the ISM licence-free frequency band 902…928 MHz. In the design of the radio modem, special attention was paid on the dependability of the transferred data. Good receiver sensitivity and selectivity as well as use of the Frequency Hopping Spread Spectrum (FHSS) technology, minimize effectively the interference from other radio communication.

Building a SATELLINE-1915 network is easy and straightforward. A pair of radio modems is all you need to set up a data link – no configuration is required. If more functionality is needed, the modem can be easily configured using standard AT and binary commands.

According to the regulations of the U.S. Federal Communications Commission, the telecommunication devices operated within the 902…928 MHz band must apply the frequency hopping (FHSS) technology, using at least 50 hopping frequencies, the average occupancy of which being not greater than 0.4 seconds within a 20 second period. The SATELLINE-1915 varies pseudo-randomly the carrier frequency, with 10 defined sequences that share 50 channels. The radio modem quickly hops through multiple channels while transmitting data. A frequency-hopping scheme, combined with error detection and Automatic Repeat requests ensures that the data is reliably delivered.
