These "smart transceivers" or "network radios", which, depending on the version, offer many interesting functions, are also ideally suited for outdoor use. They are practically robust smartphones with an "Android" operating system and additional functions. They are primarily intended for mounting on a dashboard.
These devices can also be operated with gloves thanks to the large buttons. The volume can be turned up in noisy surroundings.
Depending on the brand and device type, the following are offered, among other things:
PTT (push to talk) button
Connection for external high gain antenna
Temperature range from -20 ° C to + 65 ° C
wide voltage range from 8V - 24V
and much more.
Network radio devices require a cellular network for communication! Direct radio links between such devices are not intended.
