IP based Push To Talk on a Mobile Phone

We at KEPTBUG TECHNOLOGIES Pvt. Ltd is providing a solution which include IP based Push To

Talk on a Mobile Phone

Push-to-talk (PTT) is a new approach to voice communication which emulates walkie-talkie system.

The main purpose of this project is to implement PTT on a cellular mobile phone (PoC).

 

PoC is an instant messaging service like a voice SMS. Instead of dialing, you “push” a button and

speak. When you release the button the message is sent. Communication is bidirectional but not

simultaneous (half-duplex).

 

The project was implemented on two platforms, PC and mobile phone. The PC PTT was

implemented through client server approach whilst the mobile PTT (PoC) through peer-to-peer

approach. Several software engineering testing strategies were used during testing. 6 users

participated in the test  and the results gathered through questionnaires.

 

The results showed that, half-duplex communication is efficient and yet very economical due it’s less

usage of system resources. The PC application used approximately 2% of CPU and about 0.09% of 

bandwidth.
