In this part of the assignment I am firstly going to explain the effectiveness of Wireless Communication, its advantages and disadvantages. This will include the different types of Wireless technologies and how they will make transmitting data easier or harder than ever. Also I will talk about Wired communication which is one of the older technologies but now we have several different types of media forms on wired communications and they all do a different job. Wireless Technologies could be satellite links or Radio communication. They all have good and bad points to discuss. Wired Technology could include twisted pair, Fibre optic or broadband over power lines.
Wireless communication has transformed the way we communicate to each other.

Microwave signals tend to be 300MHz to 300GHz which is a signal that is sent through the air. Satellites are stations which will orbit the earth in a pattern; if there was no relay stations then we would all rely on the satellite to be in the same position as you are so that you can access the data. What a relay station does is it will catch the signal, amplifies it and then retransmits to you or another station which will send the data throughout the whole of Britain. Our nearest station is in Birmingham, the city centre [2]. So the disadvantages of using a satellite uplink is that if you were a reporter on a case in Africa and wanted to broadcast something via a satellite without relay stations you may be cut off and your signal will be very weak [1], plus you will need to do it at the right time of day otherwise the satellite you were after would be over another country or state in Africa which is no help to you. The advantage of satellite communication is that if there is a massive mountain which will otherwise block a microwave relay station from getting past the satellite will be able to pick up that signal from the other side and then transfer it to the other side of the mountain and then relay the signal again. The most common satellites are the low orbit types which are approximately 35000 meters above the earth, so the satellite will appear stationary and …show more content…
In Wireless communication like we have just discussed, if there is a mountain in the way the wireless signal will get lost but if there was a cable going around the mountain signal will not be lost at all, it will just carry on. The first cable I will talk about is the twisted pair type of media. This is mainly used for Ethernet and telephone networking, so this type of cable would be used inside a LAN mostly. The advantages of this cable would be that it can also be used for Telephone service which means that when you dial someone the pulses of electrical charges will be pulsating through the cable through different types of terminal equipment to reach its destination. The disadvantage of using this type of cable would be that there is a transmission and distance limit that will mean that every mile or more you will need to use a repeater so that it can relay the signal and send it again through the same cable, this could cause signal

Apart from having the capacity of withstanding harsh climatic conditions like the Hurricane Katrina, Municipal Wi-Fi also provides free accessible internet to the constituents. The high cost of operation can be minimized if the government and private firms collaborate to provide Wi-Fi services.

The deployment of wireless technology has taken by both of the Giant company, FedEx and UPS in order to keep the company competitive advantage. The Bluetooth short – range wireless specification, 802.11b wireless LANs, and general packet radio service (GPRS) are the wireless solution for both big companies. These lead to the operational efficiency, saving cost – the critical business requirement, and increasing customer satisfaction while also doing more with the same resources. The devotement of $100 million had been done by these two firms to wireless initiatives. The two companies are exploiting new wireless technologies in their differing attempts at aiding the two main components of their operations: pickup/delivery and packing/sorting. Both are also looking ahead for radio frequency identification (RFID) and GPS wireless technologies.

The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.
c) Cheaper Internet in Aircrafts: The passengers travelling in aircrafts get access to low speed internet at a very high rate. Also Wi-Fi is not used because it may interfere with the navigational systems of the pilots. In aircrafts Li-Fi can be used for data transmission. Li-Fi can easily provide high speed internet via every light source such as overhead reading bulb, etc. present inside the

Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Users are then directly joined to other computer users at their own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important, these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements. . It is faster than cellular phones and faster than fax machines.
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
