  • The Empirical Formulation Of Radio Wave Propomentation Models

    empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance and other conditions. • These models predict the path loss (i.e. the reduction in power density of an electromagnetic wave as it propagates through space or underground) of a transmitter and also the effective coverage area of transmitter. We know that when a signal travels from a wireless channel, it undergoes various types of Propagation Effects like – Reflection,…

  • Inter Symbol Interference Analysis

    signal is large. This amplitude variations in the received signal called signal fading, are due to the time-variant characteristics of the channel. Relative motion between Tx and Rx (or surrounding objects causing e.g. reflection) causes random frequency modulation. Figure 11 Multipath propagation Each multipath component has different Doppler shift. The Doppler shift can be calculated by using: fd=Vλcosα V is the velocity of the…

  • Importance Of Position Location Systems

    smaller the size of each and that translates into greater accuracy. However, more cells increase the cost of purchase and installation. Another critical consideration is the need to have a host computer (PDA, Laptop, etc) to support the Bluetooth radio to be located. This means that it is currently impractical to located people or other devices that don’t have a built-in computer. ii) IEEE 802.11b (WiFi) The WiFi standard is a longer range, higher bandwidth communication protocol than…
