The General Packet Radio Service (GPRS) is an enhancement of the current GSMservices. GPRS makes an efficient use of the radio resources, allocating channels onlywhen needed and releasing them when there is no data traffic. Users can be connected tothe network continuously, paying only for the data traffic instead of paying for theconnection time. GPRS is a packet switched based technology, and hence more suitablefor applications such as web browsing or electronic mail, where data traffic is bursty type. GPRS is a first step towards the so-called mobile third generation. Bluetooth is a short-range wireless radio technology that enables communication betweenelectronic devices. Bluetooth radio al1ows the creation of ad-hoc networks, in which onemaster can connect to up to seven slaves. Communication may include data or voice. Dataconnections can be either connection-oriented or connectionless. The scope of this thesis is a study of how the dial-up networking scenario works in practise in a mobile handset by using Bluetooth between the laptop and the mobile station, and GPRS between the mobile station and the network. Features of both technologies and common applications are described. A short comparison with IrDA and GSM has also been done. /Kir10 |
