With the ubiquitous use of mobile phones, there has been a recovery. Although some people pay attention to good cell phone etiquette, many people still discuss their private, professional, or worldly affairs in public places and force anyone nearby to listen.

As long as the device is activated, you cannot reconnect if there is insufficient distance between the device and the source.

Factories, churches, libraries, courts and entrepreneurs looking to increase employee productivity are all examples of potential technology customers.
