ABSTRACT
A network extension seen from the viewpoint of the traditional mobile network, a Bluetooth-based PAN opens up a new way of extending mobile networks into the user domain. Someone on a trip who has access to a Bluetooth PAN could use the General Packet Radio Service/Universal Mobile Telecommunication System (GPRS/UMTS) mobile phone as a gateway to the Internet or to a corporate IP network. In terms of traffic load in the network, the aggregate traffic of the PAN would typically exceed that of the mobile phone. In addition, if Bluetooth PANs could be interconnected with scatternets, this capacity would be increased. Figure 10.1 shows a scenario in which four Bluetooth PANs are used.
