  • Advantage Of Wifi Technology

    It uses 868 MHz band in Europe, 915 MHz band in the USA and Australia, and 2.4 GHz in other regions. ZigBee is used for long distance transmission between devices in wireless mesh network. It has low cost, low data transfer rate, short latency time, comparing to WiFi standards. The technology uses the RSS method to estimate the distance between two or more zigbee sensor devices[36] . 2.5.3 Short Distance Wireless Technology 2.5.3.1 Bluetooth Bluetooth is intended to enable short range wireless communication between devices. Bluetooth communicates utilized radio waves with frequencies between 2.402 GHz and 2.480 GHz as WiFi does. Bluetooth concerns the power consumption, it uses a very low transmission power. So the coverage of Bluetooth is shorter than WiFi and other WLAN technology. Hence, Bluetooth is not suitable for localization for large area [37]. 2.5.3.2 Ultra-Wide Band The Federal Communication Commission FCC has determined UWB bandwidth more than 500MHz and carrier frequency larger than 2.5 GHz. A Large bandwidth in UWB due to high speed communication, high…

  • Importance Of Position Location Systems

    MODELING A BLUETOOTH INDOOR LOCATION SYSTEM BASED ON LOCATION FINGERPRINTING 1. INTRODUCTION: Position location systems are becoming increasingly important as add-ons to today’s pervasive wireless technology. Location – aware services are based on some form of positioning techniques. Positioning systems enable context – aware computing with location awareness [1]. Information such as location, group, object that are directly related to an application’s operating environment are often…

  • Essay On Advantages And Disadvantages Of OFDM

    with the signal from an adjacent one. because of scarcity of digital filters it was very difficult to filter closely packed adjacent channels. 2.Multicarrier modulation:- it is not convenient and efficient to transfer a high rate data stream through a channel, the signal is divided into a number of signals over that frequency range. Each of these signals are individually modulated and transmitted over the channel. At the receiver end, these signals are fed to a demux where it is demodulated…
