![]() ![]() Bluetooth devices can be classified into three types of power classes. The data rate of the Bluetooth network at physical layer is 24 Mbit sec -1 (Bluetooth Specification 3.0, 2010). It is used to transmit both synchronous as well as asynchronous data. The range of Bluetooth network can be 1 to 100 m. ![]() ![]() ![]() The communication changes the transmitting and receiving frequency 1600 times per second, using 79 different frequencies. All the work is being done in BlueZ using Linux kernel 2.6.īluetooth is a short range wireless radio technology that enables Bluetooth enabled electrical devices to wirelessly communicate in the 2.45 GHz ISM (license free) frequency band ( Bluetooth, 2001). The parameter selected for distance based measurement can be used as threshold value for handover initiation. The main objective of this paper is to analyze the relation between Signal parameters and Handover. Furthermore this paper discusses location estimation techniques, Bluetooth signal parameters for distance estimation and finally experimental analysis of signal parameters and their comparisons with distance is discussed. According to the experimental analysis based on Bluetooth specifications, only Received Power RX is best suited for distance estimation and handover decision. These parameters are Received Signal Strength Indicator (RSSI), Link Quality (LQ), Transmitted Power Link (TPL) and Received Power (RX). This paper presents Bluetooth handover concept in terms of measuring the signal parameters with respect to localization. Currently Bluetooth does not support any handover protocol in which handoff occurs dynamically, when a Bluetooth device is moving out of the piconet.
