License Free VHF CB like service available in Germany only. 149.0125 MHz to 149.125 MHz (6.25 kHz and 12.5 kHz interleaved or overlaid channels, 149.021875 MHz to 149.115625 digital only, 149.025 MHz to 149.1125 MHz analog/digital).
Freenet was originally a trade name used by Motorola to market license-free handheld radios to business/personal users in Germany. 6 analog voice or digital voice channels (narrow FM or NFM, 12.5 kHz channel spacing) with 12 digital voice/data only channels overlaid (6.25 kHz channel spacing) allowed since 2017. Similar to MURS in the United States and 245 MHz VHF CB in Thailand. Like MURS, the Freenet frequencies are interleaved with business or commercial band frequencies that require a regular business radio license to operate on. German law prohibits using the Freenet frequencies at elevations of 600 meters or higher (no transmissions from mountaintops, etc.) although this is apparently widely ignored.
Maximum power output 500mW / 0.5 watts. German law permits handheld transceivers only (only portable radios may be used). Simplex only. Repeaters are strictly prohibited although the law appears to be murky regarding interconnection between Freenet VHF devices and other bands and/or Internet linking (eg. to CB networks or PMR446 networks).
Much like the MURS service, there is some use of these frequencies with modified amateur radio or commercial equipment capable of transmitting at much higher power levels.
Channels 1-6 are for analog FM voice or digital voice/data use (12.5 kHz "wideband" channels), channels 7-18 are for digital voice or data only (6.25 kHz narrowband channels)
