    ASTRACT

    Network planning and design is an iterative process, encompassing topological

    design, network-synthesis, and network-realization, and is aimed at ensuring that a new

    network or service meets the needs of the subscriber and operator. The process can be tailored

    according to each new network or service.

    A traditional network planning methodology involves five layers of planning, namely:

    business planning

    long-term and medium-term network planning

    short-term network planning

    T asset sourcing

    !perations and maintenance.

    "ach of these layers incorporates plans for different time horizons, i.e. the business planning

    layer determines the planning that the operator must perform to ensure that the network will

    perform as re#uired for its intended life-span. The !perations and $aintenance layer,

    however, e%amines how the network will run on a day-to-day basis.

    The network planning process begins with the ac#uisition of e%ternal information. This

    includes:

    &orecasts of how the new network'service will operate(

    The economic information concerning costs( and

    The technical details of the network)s capabilities.

    t should be borne in mind that planning a new network'service involves implementing the

    new system across the first four layers of the !* +eference $odel.This means that even

    before the network planning process begins, choices must be made, involvingprotocolsand

    transmission technologies.

    !nce the initial decisions have been made, the network planning process involves three main

    steps:

    Topological design: This stage involves determining where to place the components

    and how to connect them. The topological optimization methods that can be used in

    this stage come from an area of mathematics called raph Theory. These methods

    involve determining the costs of transmission and the cost of switching, and thereby

    determining the optimum connection matri% and location of switches and

    concentrators.

    Network-synthesis: This stage involves determining the size of the components used,

    sub/ect toperformance criteriasuch as the rade of *erviceo*. The method used

    is known as 0Nonlinear !ptimization0, and involves determining the topology,

    re#uired o*, cost of transmission, etc., and using this information to calculate a

    routing plan, and the size of the components.

    Network realization: This stage involves determining how to meet capacity

    re#uirements, and ensure reliability within the network. The method used is known as

    0$ulticommodity &low !ptimization0, and involves determining all information

    relating to demand, costs and reliability, and then using this information to calculate

    an actual physical circuit plan.

    These steps are interrelated and are therefore performed iteratively, and in parallel with one

    another. The planning process is highly comple%, meaning that each interaction, an analyst

    must increase his planning horizons, and in so doing, he must generate plans for the various

    layers outlined above.

    Stat!!nt "f t#! Pr"&l!

    The study re#uires establishing a network within locos Norte 1ollege of Arts and

    Trades. The network is designed to ensure ade#uate coverage within the defined service area.

    The secondary consideration is to guarantee the capacity re#uirements of the users within the

    defined service area are satisfied. The capacity calculation should account for all the

    classrooms and areas within the vicinity.

    !verall, the study aims to provide the best network connectivity with all the buildings

    inside the school and the availability of internet in any area of the school.

    This study will serve as a template in planning for reliable and fle%ible network

    system for all the buildings and area of the school. &urthermore, it presents information on

    the planning and engineering of local area networking.

    S("p! an) Liitati"n

    This study focuses on establishing a network system within the vicinity of locos

    Norte 1ollege of Arts and Trades. The network must be established on a wired and wireless

    communication with a repeater to be use because of line losses. The network system is to be

    done within locos Norte 1ollege of Arts and Trades.
