VoIP - IP Telephony White Papers

More Efficient and Cost-Effective Use of Precious Bandwidth

Overview HSDPA is a technology upgrade to current UMTS networks that delivers superior speed, capacity and efficiency improvements. HSDPA is the key feature of the 3GPP's Release 5 specification that was approved in 1999. Operators and the investment community know that for the UMTS business model to work, mobile data subscription rates have to grow profitably and exponentially; for example, the cost to deliver a 10Mbyte file with HSDPA would be one-fifteenth the amount that it would take to deliver the file via GPRS and one-fifth of the cost to send the same file via UMTS Release 99.
