Abstract:
Public Switched Telephone Networks (PSTNs) are predominantly comprised of proprietary protocols and are not well suited to integration with the ever expanding Voice over IP (VoIP) network. PSTNs have evolved from analogue circuit switched systems and purely fixed line services, to the digital and mobile realms, but still remain proprietary. With the advent of wireless technologies and the explosion in VoIP services, the combination of these two technologies results in a large number of integration possibilities and inter-connection of systems. In this paper, we show how existing technologies can be used in the creation of community telephone networks. Specifically, we provide an overview of our system (Blue Bridge), which performs the bridging of Bluetooth and IEEE 802.11 wireless. We also provide an overview of the associated lightweight hybrid protocol (Linkage), which delivers status updates and data transmissions.
