F22+ is an innovative wireless communication device, which is the combination of Android smartphone and walkie talkie. It’s working based on 3G WCDMA or Wifi to achieve unlimited talk range, so that users can keep in touch anywhere they go.
First, user need to insert 3G SIM card as our regular mobile phone. Users can make any phone call for personal use or for something emergency users need to deal with.
Second, users need to install PTT application, for example “Zello” or user’s own PTT application to send voice messages to their partners via PTT button, even though with the screen off. And all the info users have sent will be recorded on PTT application, so users won’t miss any important details they need. These functions perfectly fit patrolling, police, factory keeper, school security etc.
