How Mobile Wi-Fi Calling Works
- Mobile Wi-Fi calling utilizes the same technology as VoIP calling technology, but it's accessible via a wireless Internet connection instead of a wired Internet connection. VoIP technology transfers data and information over the Internet via an IP address instead of through phone lines or radio frequencies like traditional phone communications.
- Wi-Fi calling is especially helpful in preventing a phenomenon associated with cellular communications called "drop out." This occurs when radio frequency signals sent from a nearby cell phone tower are unable to reach the handset. It commonly occurs in dense urban areas or in impenetrable concrete or steel buildings. Wi-Fi calling uses a signal from a Wi-Fi LAN, so the signal is broadcast and picked up from a much shorter range -- and inside of impenetrable surfaces.
- Assuming you are using a handset that has Wi-Fi connection capabilities, calls are capable of transferring from cellular communication to Wi-Fi, and vice-versa in mid-call. If a Wi-Fi calling-enabled handset is being used, this may provide additional coverage in areas where service was not previously available. In simple terms, when using a Wi-Fi-enabled cell phone, a Wi-Fi LAN acts as a repeater for a cellular signal.
- For a smartphone to be enabled with Wi-Fi calling capabilities, the phone must come equipped with a preloaded application. According to Kineto Wireless, the company responsible for developing this technology, a Wi-Fi calling application cannot be purchased retroactively on the marketplace. It is important to check with wireless service providers to see if they offer Wi-Fi calling service as well as handsets that support the technology.
