Crimes committed using mobile computing devices such as laptops and Personal Digital Assistants (PDAs) with Wireless Fidelity (Wi-Fi) technology implicate accessing another Users Internet network connection without permission. “Wi-Fi networks use radio technologies called IEEE 802.11a, 802.11b or 802.11g to provide secure, reliable, fast wireless connectivity”. A wi-fi connection allows a User to remotely connect […]
In recent years there has been a discernible shift in the paradigms that dictate standards and protocols in the world of software development and dissemination. In the late nineties, developers and users alike had come to see the old paradigms of ‘closed source’ development of proprietary software as a fusty anachronism that was no longer […]
1. Introduction Bluetooth is an open standard which provides communication at short-range between mobile devices which operate in the unlicensed range of 2.4 GHz. With its short range and low power requirements it enables the deployment of personal area networks. The ubiquity of other networking technologies such as IEEE 802.11 Local Area Networks means that […]
