Wireless VoIP is running over Wireless LAN or WLANs. It is typically compliant with the 802.11 standard. If the callers are within range of a WLAN access and using VoIP handset, they can make and receive calls easily over the existing network.
Now Wireless VoIP is gaining adoption in certain service industries, such as health care and retail, where worker mobility is critical to a productive workforce.
