Improving Internet Connectivity

For me, there are so many ways to resolve the issue in terms of technology, infrastructures, innovations, steps, processes, amongst others. But before you think of the solutions, you have to consider the university’s budget first. Every organization and/ or institutions always have to consider the cost before planning the implement the changes or improvements in line with the pros and cons. And the university like the University of Southeastern Philippines is no exception. Aside form this fact, we have also to emphasize that USeP is a state university which means that its budget also depends from the budget allotted to them by the government and therefore, limited.

This means that as an IT consultant, I have to find ways to improve the university’s internet connection without spending so much money. So what are we focusing on is the cost and the speed of the internet connection.

But before we discuss about some solutions on the issue, let me introduce my job first, IT consultant.

What is IT consultant?

As the name suggests, Information Technology consultants work to improve the structure and efficiency of an organization’s IT systems. IT consultant works in partnership with clients, advising them how to use information technology in order to meet their objectives or overcome their problems.

IT consultants may be involved in many activities, including marketing, project management, client relationship management and systems development.

They may also be responsible for training and feedback. In many organizations, these tasks will be carried out by an IT project team. IT consultants are increasingly involved in sales and development, as well as technical duties. The following are some of the typical work activities of an IT consultant.

• meeting with clients to determine requirements;
• working with clients to define the scope of a project;
• planning timescales and the resources needed;
• clarifying a client's system specifications, understanding their work practices and the nature of their business;
• traveling to customer sites;
• liaising with staff at all levels of a client organization;
• defining software, hardware and network requirements;
• analyzing IT requirements within companies and giving independent and objective advice on the use of IT;
• developing agreed solutions and implementing new systems;
• presenting solutions in written or oral reports;
• helping clients with change-management activities;
• project managing the design and implementation of preferred solutions;
• purchasing systems where appropriate;
• designing, testing, installing and monitoring new systems;
• preparing documentation and presenting progress reports to customers;
• organizing training for users and other consultants;
• being involved in sales and support and, where appropriate, maintaining contact with client organizations;
• Identifying potential clients and building and maintaining contacts.

And now, we have to discuss the internet connectivity and its improvement in the university. As what I’ve said our focus will be on the speed of the internet.

But what is Internet?

Internet is a shortened term for Internetwork. Internetwork is simply defined as network of networks based on many underlying hardware technologies, but unified by an internetworking standard, the Internet Protocol Suite (TCP/IP). It is resulting from the connection of two or more computer networks via gateways using a common routing technology. Gateways are the original term for routers but were deprecated in this context because it brings confusion with the functionally different devices using at the same time.

The interconnection of networks with bridges (link layer devices) is sometimes incorrectly termed “internetworking”, but the resulting system is simply a larger, single subnetwork and no internetworking protocol (IP) is required to traverse it. However, a single computer network may be converted into an internetwork by dividing the network into segments and then adding routers between the segments.


At last, we are done with the definition of terms and now, we can start enumerating the helpful ways to improve the internet connection.

Wink TECHNOLOGYWink

Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems.
Speed is the most important thing in Internet. Most speeds are advertised in their bit speed, i.e. 1 mbps/256kbps, all with small bs. What’s the significance of this thought? It differentiates the capital B and the lower case b. B means byte while b is foe bits, the difference is that 1 byte equals 8 bits.
There are common methods of internet access which includes dial-up, landline (over coaxial cables, fiber optics or copper wires), T-lines, Wi-Fi, satellitre and cell phones.
Here is the table which summarizes the technologies and their characteristics in terms of typical and maximum speed.
Speed Table

Technology Typical Speed Maximum Speed
56K Modem 48kbps 56kbps
ISDN Single Channel: 64kbps
Dual Channel: 128kbps Same as Typical
ADSL 1-2mbps 8mbps
ADSL2+ not in use 25mbps
SDSL 1-2mbps 3mbps
Cable 2mbps 8mbps
Wireless 1mbps 12mbps

Dial-up connections

The most common type of the internet connection available from ISPsn and the slowest and yet the least expensive. In this case, if the university really needs to have an improved internet connection then, this is not the answer.

56K Modem

This is the original method most of us used to connect to the internet. It's limited to below 56kbps because of what the line can handle. This technology works by converting digital signals from your computer into a signal for the phone line, using a modem, at the other end, it's converted back again.

ISDN - Integrated Services Digital Network

This was the faster option available to many dialup users, with a guaranteed connection of 64 or 128, depending on the number of channels used. A line was typically split into 2 channels, and you would either use both for data, or one for data and the other for simultaneous voice.

DSL - Digital Subscriber Line

DSL or xDSL is a family of technologies that provides digital data transmission over the wires of a local telephone network. DSL originally stood for digital subscriber loop, but as of 2009 the term digital subscriber line has been widely adopted as a more marketing-friendly term for ADSL, the most popular version of consumer-ready DSL. DSL can be used at the same time and on the same telephone line with regular telephone, as it uses high frequency bands, while regular telephone uses low frequency.

This category of technologies is currently the fastest available right now. DSL is the superset of many technologies, where data is transmitted down your normal copper line as digital signals, because voice uses a different frequency, you can do both at once, splitters at either end split the voice and the data into separate streams.

DSL technologies have a limit on the distance between the premises and your local telephone exchange, which is usually between 3KM and 5KM depending on the speed of the service you are applying for. The download speed of consumer DSL services typically ranges from 256 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service-level implementation. Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for the rarer Symmetric Digital Subscriber Line (SDSL).

ADSL - Asymetric Digital Subscriber Line

Often simply referred to as DSL in America, this method has a different upload and download speed, the download speed is usually much faster than upload, and is therefore ideal for the home user. It usually starts at about 256kbps rising all the way upto 8mbps in some areas, which in theory is the maximum.

Asymmetric Digital Subscriber Lines (ADSL)
have become a widely available broadband internet connection, providing a variety of data rates. The connections work by splitting the function of a phone line into separate channels for voice telephone calls and for data (intenet). Thus, a user can talk on the phone and be connected to the internet at the same time. ADSL connection services are sold with different speed specifications, below are some common configurations:

• 512 kbits/s/128 bit/s
• 1Mbit/s/256kbit/s
• 3 Mbit/s768kbit/s

ADSL2+

Probably able to carry upto 25mbps downstream, this is a new technology being trialled in some areas.

SDSL - Symetric Digital Subscriber Line

This method has the same upload and downloads speed, and so therefore the maximum download must be lower. This is more common for business use, or dedicated gamers, as the speed with which you can send data is faster than that of normal ADSL.

Cable

This system uses a mixture of fibre optics, and coaxial cable to your home, not your existing phone line, therefore the technology must be available in your area.
Cable Internet is the principal competitor of the DSL which offers a range of prices and speeds overlapping that of DSL, but tends to concentrate more on the high end of the market.

Wireless

This system uses radio technology, and a receiver based on your premises, depending on the technology, the receiver may be attached to your roof or inside the home. The speeds above were based on the UMTS TDD standards, in use by a UK wireless network (provided by Hong Kong).

To sum it up, among the above-mentioned types of common used connections, I highly recommend the use of DSL.

Wink INFRASTRUCTURESWink

Infrastructure can be defined as the basic physical and organizational structures needed for the operation of a society or enterprise.

The Internet has placed heavy demands on infrastructure with its requirement for high-quality, high-speed connections. Internet service providers (ISPs) need access to international communication lines in order to interconnect with Internet backbones, as well as needing local access for their customers.

DSL connection is almost of no use if the university’s hardware can only comply with the minimum speed requirement. I mean, what is the use of fast internet connection if our computers and other devices have no capacity to manage large data in a second?
I also suggest in improving the computer units of the university. Units which are able to manage large amount of data I short span of time.

For the internet backbone, I suggest that the university only use the existing media in terms of what they only needed. Be it a copper wire or fiber optics. In consideration to the cost, fiber optics is known to be at least the most efficient in fast traversal of the data but it’s also expensive. Fiber optics is ideal for networks with a long distance. In the case of the university, the distances of the computer units are not too long to require fiber optics. Thus, I suggest the use of copper wires, it is just moderately expensive and yet effective.

Wink INNOVATIONSWink

The term innovation refers to a new way of doing something. It may refer to incremental and emergent or radical and revolutionary changes in thinking, products, processes, or organizations.
The first tip is to get rid of your modem and move to ADSL. Yes, broadband is available at low cost in most areas.

Use a high speed port. This'll only apply to readers with really old computers. The serial port may use an old, slow chip called a UART. The answer is to fit a high speed serial port with a 16550 UART chip or to fit an internal modem which includes one of these beasties.

Organizations and institutions like the university would also have to have the acceptance to change. If in the current situation, they are not using the DSL connection or the copper wire media, then it’s the time they have to weigh the costs and advantages of the said technology and infrastructure with the existing ones.

This will guarantee a strong campus network infrastructure that will improve the University’s services, operations, managerial decision-making and strategic development.

Wink PROCESSESWink

Process or method is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. It often can be visualized with a flowchart as a sequence of activities.

Here are some of the processes or steps which will help in improving the speed of the internet.

1.) Use Anti-Spyware:

There are numerous programs that can be obtained over the Internet that are harmful to your computer. These are not viruses or worms. Instead, they are known as "Spyware."

Spyware is not easy to define, because there are so many variations of it. In the most typical case, Spyware usually arrives on your computer because you agreed to permit it. Perhaps you signed up for a free tool bar, or downloaded free software, or you are using some web-based server such as a file-sharing site.

Some Spyware merely records information about what web sites you have visited, and transmits that information back to Spy. This slows down your computer because it takes time to send back this information. Some Spyware will actually hijack your computer. Many of the sophisticated Spammers (people who send junk mail) will hijack your computer and send off a few hundred junk emails without you ever knowing about it.

2.) Use Firewall and kill Pop Ups

Another factor that slows down surfing, and is downright annoying anyway, is pop-up advertising. Pop-ups cost you bandwidth, which results in a loss of speed. Part of that suite of programs I mentioned earlier includes a pop-up killer.

Finally, there are problems that occur because others are attempting to gain information and/or control of your computer. They may do this by "pinging" your computer. A "Ping" is a request made by another computer for the identification number of your computer. Again, this information can be used to hijack your machine. Installing software known as a “Firewall” can prevent this.

3.) Use Anti-Virus:

Another class of programs that we don't need are virus/worms. If you install the program I suggest for Anti-Virus, be sure to uninstall any other virus program you have running on your computer. It is not unusual for virus programs to disagree on which one is in control of your computer.

4.) Tweak your settings
Your PC has some settings that may improve modem throughput. All data sent over the internet goes in data packets.

5.) Use FTP download wherever possible.

If you want to download files, you can often choose between FTP or HTML download. FTP, (File Transfer Protocol,) is much faster for file transfers so you should choose that when you can.

6.) Use a download tool.

There's nothing more frustrating than losing a connection near the end of a one hour download.

7.) Use a faster browser.

Once you've connected to AOL, you can start any browser and run it in a second window. Opera is one of the fastest so why not download a free copy and give it a test run?

8.) Manage your cache.

Every time you use the internet, images and other files are downloaded onto your hard disk.

9.) Define a blank homepage.

Each time you start a browser outside your AOL window, the browser will go to the defined homepage.

10.) Don't display images.

Text only windows are much faster to download. You can easily restore images when required. Here's how to set whether to display images: From Internet Options (see above) select the Advanced tab. Scroll down until you see the multimedia section, then select or deselect "Show pictures." Select Apply then OK to save your change.

Finally, I strongly recommend that you keep informed these programs and their databases on a regular basis. If you don't, you won't be fully protected. My rule of thumb is twice a week.

11.)Update your Windows
If you are running any version of windows, you would also be well advised to download and install all available patches, fixes and updates from the Microsoft Windows Update web site at: http://v4.windowsupdate.microsoft.com/en/default.asp

That’s all. I hope I have successfully done my part as IT consultant.The above-mentioned tips and ways are only my suggestions to the university president if ever. In the end, it’s up to the president to weigh his decisions with the aide of my advice.
