"Voice over IP (VoIP) is a more and more popular way of communication, because people can use it for long distances with very low cost. The importance of mobile broadband is also increasing, since the need for immediate information access is bigger than ever. The authors can combine these fields, and use VoIP in mobile data networks, but because of the QoS needs, they have to consider some problems or limitations. In this paper, they examined the connection between delay, as one of the most important QoS parameter, and the used VoIP codec, the payload size, and the mobile broadband technology in HSDPA and HSPA data networks."
