electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

Bluetooth device discovery is a time-intensive phase of the Bluetooth connection-establishment procedure. In this paper we propose a technique that integrates existing IrDA technology with Bluetooth technology to improve the ad hoc connection establishment time of Bluetooth devices. We accomplish this improvement by first establishing an IrDA connection between two devices equipped with both Bl...

The Bluetooth technology is the convergence of Mobile Communication and Computing Applications. The set of Mobile Devices ”Laptops, Notebook Computers,PDA’s,Mobile Smart Phones etc” connected by Bluetooth protocol forms a Bluetooth Network or Bluetooth Piconet or WPAN.Even through the devices have numerous benefits its open nature increases the threats and risks being posed on them. The wired n...

This Paper on Bluetooth Indoor Positioning System is the intersection of Bluetooth Technology and Indoor Positioning Systems. Almost every smartphone today is Bluetooth enabled, making the use of the technology more flexible. We aim at using the RSSI value of Bluetooth signals to track the location of a device. Keywords— Bluetooth-Android-Indoor Positioning

Bluetooth is developed for short range communication. Bluetooth Devices are normally having low power and low cost. This is a wireless communication technology designed to connect phones, laptops and PDAs. The greater availability of portable devices with Bluetooth connectivity imposes wireless connection between enabled devices. On an average the range of Bluetooth devices is about 10 meters. ...

In this document, the impact of a 20dBm 802.11 Direct-Sequence WLAN system on a 0dBm Bluetooth link is studied. A typical office environment is assumed with a small number of WLAN access points and a large number of WLAN terminals. The study differentiates between the impact on the Bluetooth data link and the impact on the Bluetooth voice link. Results show that a Bluetooth voice link is distur...

Bluetooth system has been developed by Bluetooth Special Interest Group (Bluetooth SIG) as a cable replacement for short-range connectivity. In Bluetooth, special effort has been taken to develop and standardise adequate security mechanisms and procedures for protecting the wireless radio link. This set of mechanisms is defined in the Bluetooth Baseband specification [5] and is referred to as B...

Bluetooth is an emerging standard for Wireless Personal Area Networks (WPANs): short range, ad hoc wireless networks [1]. Originally, Bluetooth was envisaged as a wireless cable replacement technique, which is why the basic RF range of Bluetooth devices is only about 10 meters [2]. However, the number of possible uses of Bluetooth have increased to include different networking tasks between com...
