Carlson Listen

Carlson Listen-Listen

Traditional UHF radios in most parts of the world are limited to half-watt or one-watt power output, which gives a 1 km (0.62 mile)  to 2 km (1.24 mile) range at best. In many regions Licenses may be required to operate UHF radios. With no licensing and no restriction on data format or communication range, Carlson Listen-Listen will work at base line lengths up to  30 km (18.6 miles) depending on conditions.

Carlson Listen-Listen uses an internet connection between the base and rover instead of the UHF radios. The Base uses the Cellular SIM card and the Rover can use any internet connection method. Fixed or static IP address SIMs are not required.  In addition, multiple rovers can simultaneously connect to a single base using Listen-Listen.
