Academic institutions can garner all the benefits of the Internet age by integrating information and communications technology (ICT) with their teaching and learning environments. ICT is an extension of the term for information technology (IT), emphasizing the unification of telecommunications, computers, software, storage, and audio-visual components within a network.

The quality of education can be significantly improved through the sharing of skills, resources, content, and faculty development. IT content and resources should be available to both faculty and students throughout the campus. To this end, academic institutions must establish a network in each of their campuses, achieving the same speed of data transfer at each building.

Typically, a campus network is comprised of several local area networks (LANs) that are interconnected inside a specific geographical area. Networking components, such as switches, routers, and firewalls, and transmission media, such as copper cable and optical fiber, are utilized for interconnection and communication between connected devices.

Campus Network Topology

For academic institutions like colleges or universities, a campus area network should be interconnected to various types of buildings, including administrative, academic, library, student center, hostel, guest house, sports facility, conference, technology, training, and laboratory.

A campus network will be interconnected via high-speed Ethernet cabling over optical fiber of up to 10GB capability. For the efficient processing of data and information traffic using distribution, access and core segments, tiered hierarchal architecture is utilized.

Every building, block, center, and residential complex will be connected by high-speed optical fiber cable. Moreover, every node within a building will be connected with UTP copper cable that supports gigabit speed.

The conference rooms, teaching halls, and common areas inside each campus will be Wi-Fi enabled through the deployment of 802.11 based wireless access points with central authentication, permitting secure network access via laptops, tablets, smartphones, and other Wi-Fi enabled devices.

Internet services, along with common applications, will also be installed at key locations, such as library study halls, allowing students, faculty, and staff easy access via desktop computers and laptops around the clock.

Cabling system designed for the purpose of security have hardly changed the last decade and a half. Delivering video images and access control data to a control room utilizing standard transmission technology is basic and familiar. What has recently changed is the transition to IP-based security products and the rapid increase in business applications, resulting in end-users expecting a greater video, audio, and data integration. All of these items require delivery over one standardized structured cable system.

As opposed to traditional video and access control systems, voice and data communications cabling systems have had numerous transformations. Functioning on structured cable systems, data networks have shifted from the pioneering 1980s proprietary cabling to standards-based cabling using optical fiber and balanced twisted pair. This has resulted in greater transmission speeds and significantly increased network bandwidth. These two elements allow a security installer to achieve integration that is demanded by clients for CCTV, access control, and other applications. Through the adoption of standardized structured cabling, installers will be able to access new streams of revenue and provide tangible benefits to users by unifying all of their systems within one cabling infrastructure.

This change in the utilization and deployment of structured cabling systems was recognized by ANSI/TIA-862-B “Structured Cabling Infrastructure Standard for Intelligent Building Systems”, which was developed by the TIA TR-42.1 Commercial Building Cabling Subcommittee and released February 2016. This standard features the requirements of several standard and developing systems that are able to use the existing cabling of buildings. It also includes Distributed Building Services that do not utilize a building’s infrastructure cabling because of application, connector, historic, and topographic limitations.

A company’s network infrastructure is crucial in the distribution of information using electronic media, including CCTV, access control, data, and voice. Functioning over a structured cabling system, this distribution network is developed for the perpetual flow of data, featuring redundancy at the heart.  Installed with centralized topology, this enabled the most facile sharing of resources achievable, along with the greatest flexibility and expandability possible.

As mentioned in Part 1, cabling utilized for network infrastructure is a crucial aspect of networking, growing in importance as new technologies are introduced. Although wireless technology has made great advancements, existing computer networks are still using cables for transferring data. Part 2 will cover Fiber Optics, USB Cables, and Crossover Cables.

Fiber Optics

In contrast to older wiring, fiber optic network cables utilize strands of glass and pulses of light to carry data. Although composed of glass, these cables can be bent and have proven their utility in wide area network (WAN) installations in office buildings, especially when long distance runs are necessary and a high volume of communication traffic is typical.

The two main fiber optic cable standards are single mode, the 100BaseBX standard, and multimode, the 100BaseSX standard. Due to single mode's higher bandwidth capacity, it is typically used by long distance telecommunications networks. On the other hand, local networks commonly utilize multimode because of its lower cost.

USB Cables

USB (Universal Serial Bus) cables, which feature twisted pair wiring, are typically used to connect a peripheral device, such as a mouse, to a computer. Dongles or special network adapters also permit the indirect connection of an Ethernet cable to a USB port.

Serial & Parallel Cables

As numerous PCs during the 1980s and early 1990s did not have Ethernet capability, along with the fact USB did not yet exist, now obsolete serial and parallel interfaces were occasionally utilized for networking PCs together. As an example, null modem cables connected the serial ports of two PCs, allowing 0.115 to 0.45 Mbps data transfer.

Crossover Cables

A null modem cable belongs in the category of crossover cables because it joins two network devices of the identical type, like two network switches or two PCs. Ethernet crossover cable usage was most commonly found in home networks years ago when two PCs were directly connected. Currently the majority of home networks are equipped with routers featuring crossover capability, making crossover cables unnecessary.

The structuring of cabling will result in better organization and easier management of the cables. If you are a building manager or business owner, you may already know a bit about structured cabling. You may be currently thinking about its installation in your premises. In the most basic terms, structured cabling allows for several devices like computers and telephones to be connected via a cabling system infrastructure. The following discusses several benefits of structured cabling for a facility or office. Consult with experienced structured cabling professionals to get the best results.

Adaptability

Structured cabling is technology that allows business managers to plan and prepare for the future, making its implementation a valuable investment. Structured cabling that installs a newer cable such as Cat 6 will provide adequate bandwidth, making it viable for an extended period as a business’ IT needs gradually expand. The high bandwidth of a structured cabling system will also give a business the increased ability to adapt newer applications, devices, and technologies.

Diagnosis and Repairs Made Easier

Whenever issues occur on multiple, disorganized cabling systems, determining the source of the problems will be difficult. Although structured cabling is a unified system, it is organized in segments, making it much easier for technicians to locate malfunctions and repair them.

Flexibility at Lower Costs

The people, equipment, and offices of an organization are not static. Businesses evolve and restructure as time passes. Employees of a department may have to move to another area. The entire area of an office may also need renovation. Typically, changes like these grind business to a halt, hurting the bottom line. However, a structured cabling system allows a company’s staff to move to another part of an office, connect, resume working, and remain productive without missing a beat.

Networking

Employees will also be able to connect their devices into any outlet of a structured cabling system as opposed to a particular wire, promoting flexibility and productivity. In addition, a structured cable system will be able to convey data in multiple forms, allowing staff on a network to connect with other computers, servers, printers, and telephones.

Simplified Management

One of the greatest advantages of a structured cabling system is the elimination of disorganized and unsightly wires. The replacement of a configuration using multiple cabling with a structured cabling system will result in easier and less costly management by technicians as they will save time on repairs and restructurings.

As mentioned in Part 1, a good network upgrade plan will make an analysis determining each aspect of SWOT: Strengths, Weaknesses, Opportunities, and Threats, helping project managers create a clear plan consisting of five phases. Part 1 discussed the first two, Gathering of Requirements and Selection & Design. Part 2 will cover the last three, Implementation, Operation, and Review & Evaluation.

3) Implementation

Proper execution of the first two phases, will allow Implementation to be performed without major issues. However, every neglected task in the first two phases will certainly have to be addressed during Implementation. A sound schedule will provide time for unanticipated problems which will minimize disruptions of the customer’s business. Maintaining communication between project designers and the client throughout installation is crucial for making a project successful.

4) Operation

After the completion of the network implementation phase, the network transitions into a production environment. The network is live and executes the tasks it’s been programmed to perform. The proper completion of all tasks before this phase will minimize unexpected incidents during the network’s operation phase.

5) Review & Evaluation

Once operational, the network’s design and implementation must be studied and assessed in terms of the design’s objectives. Typically, these tasks are performed by design team staff with the help of network members. There will be an evaluation of costs, performance, and environmental fit.

The items below are recommended for this process:

• Make a comparison between user experience and the documented goals, then make an assessment of the design’s performance.


• Make a comparison between planned designs and costs and actual results of deployment, ensuring future projects will learn from these lessons.


• Observe the operation and document all revisions, making sure the system is accountable.

Each phase should practice sound planning and conduct reviews for optimal functioning and successful installation. For ideal results, on-site technicians should participate in all phases of a network upgrade.

Planning the network upgrade for a company requires careful consideration. Similar to other projects, a need is determined, and then the upgrade process is planned from its start to conclusion. Every sound network upgrade plan will make an analysis determining each aspect of SWOT: Strengths, Weaknesses, Opportunities, and Threats. This SWOT analysis will help project managers create a clear plan that defines the tasks required and the order of the workflow.

Overview

A network constructed as a hodgepodge of devices attached using a combination of protocols and technologies is a sign of substandard initial planning. This lack of forethought results in networks that are prone to downtime, challenging maintenance, and difficult troubleshooting. This poor kind of network is commonly found at small businesses that undergo rapid and unanticipated growth. Big companies also experience this when their networks suddenly expand after a merger with or acquisition of another company. In cases where growth is expected, a company will have a better opportunity to properly plan a network upgrade that is less problematic and provide users adequate service.

Five Phases

Network upgrade planning starts after completion of the initial site survey and report. The plan will be typically divided into five phases as listed below, and each will be then discussed individually.

• Gathering of Requirements


• Selection & Design


• Implementation


• Operation


• Review & Evaluation

1) Gathering of Requirements

Once adequate data has been gathered from visits to the customer and site, the ISP design team will make an evaluation that will determine network requirements and write an analysis report.

2) Selection & Design

After the completion of the analysis report, equipment consisting of devices and cabling will be selected. Several designs will be drafted by the design team, and these will be submitted to other project members for feedback.

This process with allow participants to consider the LAN from a point of view of documentation and assess trade-offs in terms of cost and performance. In addition, design weaknesses will be discovered and solutions will be considered. Moreover, this phase will allow prototyping to determine optimum methodology. Prototypes let designers see how the network will operate before final implementation.

Part 2 will cover the next three phases, Implementation, Operation, and Review & Evaluation.
