Standards for third generation mobile communication

In mobile communications, the need for other applications than speech, such as data and video, is growing. To support these applications, the mobile communication systems must offer additional services like high speed packet switched data transmission. For GSM, additional standards are being developed to offer services which meet the requirements of next generation mobile communications. But also other new standards are under development. This paper gives an overview of the standards under development and discusses how a mobile communication network can evolve towards the next generation.
