1. Project Introduction
Telecommunication network becomes important part in an organization since it helps the enterprise to perform daily tasks that are critical to the success of business. There are many applications that a company may use including voice communication by using telephone, data (file sharing, SAP-based system etc), and Internet. For some industry like banking, telecommunication services are critical parts that they cannot perform their business without them.
Since the use of telecommunication networks is critical, therefore, the continuity of services (COS) should be maintained to prevent operation losses as the result of broken cables, failure Wi-Fi access points, and slow network connection due to incompatibility of components in the network, to name a few.
Concerning the set up of a network in a building, this paper will develop business proposal of providing new data communication infrastructure to meet particular business challenge or opportunity.
2. Organization’s Project Charter
Telecommunication network does not only enable a business to facilitate communication but also to reduce operation costs of the business by supporting the alignment and interlocking of business processes within and between organizations.
This is true since the initial investment in building a network in a building can save operational costs that makes the initial investment is justified within a designated period. Therefore, it is essential that in the building, we should pay attention to the adoption of networking technologies to reduce operational expenses including main distribution frame (MDF), intermediate distribution frame (IDF), Wi-Fi access point, cable rack, a server etcetera.
3. Total Costs Calculation
In order to figure out the total costs in developing the project in our building, we need to define and determine what components required in the network.

4. Project Performance Metrics, Critical Success Factors, and Risk Assessments
Table 2 shows the resume of performance evaluation in setting up telecommunication network.
Table 2 Performance Metrics
LAN must provide users with acceptable speed and reliability
Incompatibility of network components may slow down network access
LAN must anticipate the growth in the number of users in the future without performing any major changes to the overall design
Use of critical components like MDF/IDF and access point DO NOT anticipates the quantity requirement within the next 5 years.
LAN system that is capable of employing future technologies
Network technologies are obsolete that require complete replacement in short period
LAN must employ network monitoring and management in order to provide better services to clients
NO network monitoring system will cause incapability of network administrator to detect fault in the system
5. Physical Layout of the Data Communication Infrastructure
Figure 1 Layout of planned communication infrastructure
Figure1 exhibit the detailed layout that we will build in order to connect the premises in the building so that they can communicate each other through fiber optic cables and Wi-Fi (wireless fidelity) systems.
5.1 LAN/WAN components
In order to set up reliable and appropriate communication links typically LAN (local area network), a company must decide which topology, which will be employed in its systems. There are many options regarding the network topology including Ethernet, Token Ring, FDDI, ATM, or even a mixture. Each of the system generally can use various transmission media such as wireless connections and fiber optic communications.
Prior to the set up of LAN communications, a company must consider comprehensive factors including topology (star, mesh, or bus), transmission media (wireless or wire line/cable), transmission speed (bit rate) and many other.
5.2 Communication Protocols
In terms of protocol for LAN communications, several options exist such as Ethernet, Local Talk, Token Ring, FDDI, and ATM in which each has particular advantages and limitations as following:
This is the most widely used protocol in computer networks. This protocol runs in an access method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection). The benefit of this system is Ethernet can use multiple transmission media like twisted pairs, coaxial, fiber optic cable etc. another advantage is no-collision between two computers that send data simultaneously.
IBM develops the use of Token Ring method in a computer network in 1980s. In a token system, many computers are connected to a ring in which every time a computer sends a data, the system will tap it and deliver it to destination within a ring. This kind of protocol only works best in Star Topology that uses twisted pair cable and fiberoptic.
Fiber Distributed Data Interface (FDDI) connects two or more networks in long-distance communications. The access method in FDDI is token that employ two physical topologies. However, the transmission only runs on one ring. The second ring is used if there are troubles in the first Ring. The benefit of this protocol is they can deliver high-speed data up to 100 Mbps.
5.3 Data communication technologies to include data, voice, audio
In the designed data communication, since fiber optics and Wi-Fi support many types of communications, therefore, the network can be used to deliver multimedia (voice, video, and data)
5.4 Hardware and software components
In order to fulfill the need assessment worksheet, during the implementation, we need to set the system requirement. Table 3 describes the system requirement for my WLAN system as following:
