Certain Investigation of Qos in VoIP over 4G Networks

In earlier wireless technology, the transmission of voice with high quality is very difficult. But later this problem is solved by Voice over Internet Protocol which uses traditional Internet Protocol to transmit voice as packets. To transmit the voice over larger areas is done easily by using WiMAX. However, highly-developed areas are using WiFi, which is growing in wireless technology.
