Nobody can dream of wireless communication without the use of antennas. It’s the antenna which creates the magic in the air and makes wireless communication possible.

    In this paper authors will discuss about the cellular antennas. They will concentrate mainly on fundamentals of antenna, relationship between frequency, wavelength and dipole wave propagation and parameters of antenna like Gain, VSWR, SFR and FBR etc.

    Authors also discuss about types of down tilt, generic requirements of antennas, selection of antennas and beam forming and active antenna systems.

  • Dimensioning Tracking Area for LTE Network

    International Journal of Soft Computing and Engineering (IJSCE) ISSN: 2231-2307, Volume-4, Issue-1, March 2014

    Mobility management (MM) is one of the main
    functions in mobile networks. It aims to track the user equipment
    (UEs) and to allow calls, other mobile phone services to be
    delivered to UEs. For any mobility protocol there are two separate
    problems to be solved. One is location management (or sometimes
    called reachability), which keeps track of the positions of a UE in
    the mobile network. The other one is handover management (or
    sometimes called session continuity)…

    UE to continue its sessions while moving to another cell and
    changing its access point. This document focuses on the location
    management problems. Tracing UEs in a mobile network is the
    key task in location management. Tracking Area (TA) in LTE is a
    logical grouping of cells in a network. TA is almost the same
    concept as the Location Area (LA). In configuring TAs, a key
    consideration is to minimize the total amount of signaling
    overhead.
