Specifications of some applications based on the Bluetooth protocol stack have already been standardized by the Bluetooth Special Interest Group. Those applications can however be accessed inside a piconet, while Bluetooth devices belonging to different piconets are not able so far of cooperating in a distributed application. In this paper, a framework is proposed that allows a Bluetooth device...

This paper reports the results of an in-depth study of Bluetooth naming practices which took place in the UK in August 2006. There is a significant culture of giving Bluetooth names to mobile phones in the UK, and this paper’s main contribution is to provide an account of those Bluetooth naming practices, putting them in their social, physical and intentional context. The paper also uncovers ho...

This article provides a Bluetooth® history from 1994 to the present, as well as the Ericsson® corporation's role in the system evolution. Bluetooth operates in the ISM band between 2400MHz and 2500MHz, using FHSS on 79 channels with 1MHz spacing. This article also describes how to use Bluetooth for long-range systems with 100mW output power. An example details a discrete power amplifier (PA), t...

In our software-defined radio project we aim at combining two standards: Bluetooth and HiperLAN/2. The HiperLAN/2 receiver requires the most computation power in comparison with Bluetooth. We choose to use this computational power also for Bluetooth and look for more advanced demodulation algorithms such as a Maximum A posteriori Probability (MAP) receiver. This paper discusses a simplified MAP...

Low power is a primary concern in the field of wireless sensor networks. Bluetooth has often been labeled as an inappropriate technology in this field due to its high power consumption. However, most Bluetooth studies employ rather over–simplified, fully theoretical, or inadequate power models. We present a power model of Bluetooth including scatternet configurations and low–power sniff mode an...

Ad Hoc Networks using Bluetooth Technology and 802.11 technology have gained widespread popularity in the networking community. Whereas Bluetooth technology has certain obvious advantages like low power consumption and reliable connection, it has a low area of operation and lower bandwidth in the order of 721 kpbs. 802.11 technology on the other hand, has a wider area of operation and therefore...

This report describes the details of two new proof-of-concept Bluetooth security analysis tools and two new attacks against Bluetooth security. On-Line PIN Cracking script is a security analysis tool for on-line Bluetooth device PIN cracking. Brute-Force BD ADDR Scanning script is a security analysis tool for brute-force discovery of the addresses of Bluetooth devices that want to be private. S...

IEEE 802.11 and Bluetooth are the two different wireless systems that share the same frequency band in 2.4 GHz and are likely to interfere with each other if operating in the same environment and thus experience a severe decrease in throughput. The devices equipped with IEEE 802.11 and Bluetooth are mobiles, laptops, watches and many more and in future with WiMAX. Result is the number of co-loc...

Using handheld devices such as PDAs, cellular phones and smart phones for personal entertainment has become commonplace in today’s lifestyle. Most of these devices are equipped with Bluetooth technology that can be used to distribute entertainment contents such as music, movie clips, and commercial films. However, content sharing faces several challenges such as short communication range, limit...

Abstract—Coexistence of different wireless systems that share the same frequency band is becoming one of the most challenging issue due to the wide-spread popularity of WLANs and to the rapid development of shortrange radio systems. In this paper we consider WLANs based on the IEEE 802.11 standard and a short-range radio system based on Bluetooth specifications, which operate in the 2.4 GHz ISM...
