This paper compares the behaviour of Earliest Deadline First (EDF) and Opportunistic-EDF (O-EDF) with that of Round Robin, Proportional Fair Throughput (PFT), and Maximum Carrier to Interference ratio (MaxC/I). Video, voice and web traffic are transmitted through an HSDPA air interface. The resultant queueing delay and fairness are measured and compared for each scheduler. As part of the UMTS standard, the Third Generation Partnership Project (3GPP) included High Speed Downlink Packet Access (HSDPA) in Release 5. In HSDPA, all resources are usually made available to a single user on a Transmission Time Interval (TTI) basis.
