How wi-fi and the Internet may be used by a business.

Wi-Fi

Wi-Fi is a wireless connection to the internet, sometimes called 802.11. The wireless network works by using radio waves to send and receive signals between the devices using the wireless connection and the internet router. Once the router receives the signals from the devices it decodes the information and sends it to the internet through a physical, wired, connection. This process also works in the reverse order, as the router can receive information directly from the internet and then will send it to the wireless devices that are connected through the radio waves. This will then output the information onto the devices screen. Below is a diagram of a set up Wi-Fi connection:

Advantages

An advantage of using a Wi-Fi connection is that it is wireless, so that the device can be mobile and still be connected to the internet, as long as it is within the radio waves radius of the router. Wifi is able to transmit any type of data via the radio waves, as long as the device receiving the data is compatible with it.

Another advantage of using a Wi-Fi connection over a wired connection is that more than one device can easily connect to the connection via the router. Also this allows different types of devices to be connected to the network. Such as a mobile phone, this cannot be connected via a wired connection like a pc.

A final advantage for a Wi-Fi connection is that they are very commonly found, and very easy to set up. A lot of ISPs (internet service providers) offer a wireless connection to be set up by them when they install the internet connection. However if they do not a router and the correct devices can be easily obtained, form most computer stores, and are easily set up.

Disadvantages

A disadvantage of Wi-Fi connection is that they are easily accessible by unwanted people. This means that a lot more security is needed, on the devices using the Wi-Fi as well as the Wi-Fi router. Gaining all of the appropriate security and setting up may be time consuming and expensive.

Another disadvantage of using a Wi-Fi connection if that the connection between the router and the device may be poor. This may be down to obstacles interrupting the radio waves, or possible the antennas being positioned in poor places. However if you have a good signal on a mobile device that is moving the signal is very likely to keep changing. Also the signal may keep changing on a stationary device connected via Wi-Fi as obstacles may move in the way of the radio waves.

A final disadvantage for a Wi-Fi connection is that not all devices with an internet support can support the Wi-Fi feature. This is because it is a fairly new invention and many devices were made not knowing that Wi-Fi was going to come out shortly after.

What is needed to use aWi-Fi

The things that are needed to use a Wi-Fi connections are; internet connection, Wi-Fi router, Wi-Fi support on devices that will be using the connect, such as Wi-Fi PCI cards for a pc.

The internet connection that will be used with the Wi-Fi should preferable be a fast connection, such as broadband, as a slow connection may seem even slower through the wireless connection.

How can Wi-Fi be used in the hotel

Wi-Fi can be used within certain area of the hotel, to allow the customers to have access to the internet wirelessly. It could also be used to connect the computer systems around the hotel. This will allow each computer to be connected to each other to allow faster file sending and sharing to be done. To do this every computer will have to be connected to the wireless router, which should be located in the main area that the internet will be used.

Where the hotel could use Wi-Fi

The Wi-Fi connection should be placed throughout the hotel so that it can be used anywhere within the hotel. Doing this would probably mean having several access points to the internet connection. However it will allow a connection to the internet anywhere within the hotel.

Internet

The internet is a network of computers on a worldwide scale. The internet can be found in many places and in many forms, and is used by many people for many different things. Some of the features of the internet are:

WWW (World wide web)
FTP (File transfer protocol)
E-mail
Chat Rooms
Bulletin Boards

The interne is a screen form of communication which can process any forms of data.

For a connection to the internet to be made it must be made through a connection to an ISP (internet service provider). Once connected to an ISP the internet connection is either authorised or declined, depending on the status of whom/how/where someone is trying to connect from.

Advantages

A big advantage of using the internet is that most forms of communication can be done through it. In fact a lot of forms of communication require the internet, such as WWW based information, or e-mail.

Another advantage of using the internet is that a lot of information can be found. The easiest and fastest way to find something on the internet is through using a search engine, such as Google.

The final advantage of using the internet is that it is all one big network. This means that information from all over the world can be found out from just staying in one location whilst on the internet. There is so much information on the internet that can help with most problems, which is usually simple to find.

Disadvantages

A disadvantage of using the internet is hackers. Hackers can hack into computer systems through this network if the correct security software isn’t being used. This means that hackers can view the content of many computers that are unprepared.

Another disadvantage is that the internet costs money. The more money that is paid for an internet connection the better internet connection it should be. There are several different types of internet connection, one being ADSL and another being ISDN. An ADSL (Asymmetric Digital Subscriber Line) offers the faster connection, however it only offers a standard of one connection. This is unlike an ISDN (Integrated Services Digital Network) connection, which offers a slower connection, but the choice of two connections to one device, or separate connections to two devices.

What is needed to use the internet

To use the internet to its full potential a computer is needed. However the internet can still be used through other devices such as; mobile phones and PDAs. All of which require an internet connection also, for a mobile phone or PDA the internet connection may have to wireless.

How can the internet be used in the hotel

The internet can be used for many different reasons in the Chello Hotel. Here is a list of ways the internet may be used:

WWW browsing
E-mails
Chat Rooms
Bulletin boards
Shopping
Researching information
Entertainment
Downloading software
Uploading a website
Contacting customer

Where the hotel could use the internet

Chello Hotel could, and should, use the internet on all of the computers within the hotel. This includes computers; at the reception, in the offices, in the entertainment area, and in the seating area. This are all prime locations for which both the visitors can the staff could use.

As well as locating computers around the hotel with an internet connection Chello Hotel could also have a wireless internet connection with many access points. This would allow people to connect to the internet on there own personal portable devices.

Conclusion

After researching all of these technologies, it is noticeably that the most suitable type of information that Chello Hotel could use would be multimedia. This is because it will seem the most attractive and will attract more customers than any other type of information.

The best method of communication that would seem to attract the most customers to the hotel would be screen based. This is because it will enable the hotel to process any type of information onto it, and it will look very professional.

The technology that will allow Chello Hotel to communicate the most would be a personal computer, with an internet connection. This combination of two different technologies allows many effective and popular forms of communication to be used.

Evaluation

What is the purpose of the report?

The purpose of this report is to allow the owner of Chello Hotel to gain a full understanding of communications, and the technologies that can be used to communicate. It also tells the owner of the hotel how each technology can be used within the hotel, along with the disadvantages and advantages that come with it.

How well does the report meet its purpose?

This task meets it purpose by explaining, in detail, many different types of information which can be communicated, many different methods of communications, and many technologies which can be used to communicate. Detail is put into explaining the advantages and disadvantages for using the certain technologies, as well as explaining how the hotel can use them in good way. Also detail is put into explaining what is needed to use each method of communicated. As well as explaining in much detail images as used to demonstrate and illustrated what each technology is.

What are the good things about the report?

The first good point about the report is that it is very detailed and explains a lot about everything that is within the report. This would enable the owner of Chello Hotel to be able to read this report without having to have knowledge of each technology before hand.

The second good factor about this report is that images are used to illustrate each technology. This is good because it means that each image is used to recognise what the technologies look like.

The third good point is that this report sticks to the house style of all of the Chello Hotel documents. Even though this document is not going to be shown publicly by the hotel using the house styles still makes it more official to the hotel and more professional.

The final good point about this report is that the layout is consistent throughout. It is all fully justified, size 12, black font, apart from the headings. This is good as it sticks to the original hand drawn plan

What are the bad things about the report?/further improvements that could be made

One bad point about this report is that it is very long. This could be improved by using more bullet points instead of full sentences to get across the same points. If this method of more bullet points was used not as much detailed information would be able to be within the report.

The final bad point about the report is that not all of the images used are not in great detail. Some of the images, however, are in much detail and explain a lot about the technology. This criticism could be improved by using more diagrams of the technologies rather than photographs of them.

What went well when making the report?

Finding the resources for information to complete this report as a lot of information was in the AS Level for OCR Applied ICT book, which is mentioned in the bibliography.

Another thing that was easy throughout completing this task was designing the layout of the report. This is because the task is mainly just text therefore the layout is going to be consistent throughout, which makes it look more professional.

What was difficult when creating the report?

Creating the task was in general a very difficult task to complete. This is mainly due to the amount of researching and writing that is needed to be done. However other than this another difficult part of creating the report was finding suitable images for each technology. This task was a very time consuming and difficult to complete.

How improving the draft helped make the final report better

Creating improvements from the draft report helped with the final as it allowed me to view it and proof read it. This allowed me to correct the spelling and grammar errors which I found. Also the draft also allowed me to see the whole report as the owner of Chello Hotel would have, allowing me to judge whether it looked professional enough, or if more alterations needed to be made.

What could be done differently if this task was done again?

If I were to start this task again I would do more research on the technologies and communication methods before actually starting to write the report. This would give me a better understanding whilst I was writing, rather than me having to stop after each technology and research it whilst I am still writing.
