essay on mobile networking and its advantages and disadvantage
Answers
Advantages
There are many advantages associated with installing a wireless network compared to a wired network such as mobility, cost-effectiveness and adaptability.
Wireless Networking is relatively cheaper than wired Networks since they require no cables between the computers as well as lower long term costs due to less maintenance since there is less equipment. The reduction of cables also reduces the trip hazard caused by cables running along the floor in most homes. Most wireless network equipment is plug-and-play, which helps reduce the total cost such as vendor installation and eliminates redundancy is case of a system crash.
Wireless Networking is also very mobile and versatile; it is adaptable to most situations and requirements. Wireless networks can easily be set up and dissembled, which is perfect for many people who are on temporary worksites/homes or leased space. It can also provide networking in places where regular wire cannot reach such as the backyard in a home situation. Access points can be used to boost the wireless signal range if required. Since portable workstations such as laptops have become popular, wireless networks can provide quick and easy access to the internet and workspaces for students and teachers in universities etc. It is also extremely easy to add other components onto this type of network such as easy installation of VoIP and printers etc without the need to configure ones computer.
Disadvantages
Since wireless networking is a relatively new and contingent form of networking, it is filled with it own hazards and problems such as unreliability and security.
Wireless networks have limited bandwidth, hence they cannot support Video Teleconferencing(VTC). It is also limited in its expandability due to the lack of available wireless spectrum for it to occupy.
Wireless Network can also be a security risk if not installed and maintained properly. Wireless networks don”„¢t require any physical components to connect up to it such as wires, only a wireless adapter is required which significantly increases the accessibility of the network to potential hackers. This scenario is worsened if the network doesn”„¢t contain a password since it can then be accessed by anyone with ease.
Wireless networks also have an increased chance of jamming and interference due to external factors such as fog and dust storms or when a flying object such as an aeroplane passes over the field. When too many people in the same area use wireless networks, the band of air that they transmit signals on can become overloaded.
Answer:
Over the last few years, many cell phones have become available that allow users to access the internet while on the move. This mobile internet is enabled via technology, such as WiFi (Wireless Local Area Network) and WAP (Wireless Access Protocol). Recent figures from analysts at the Internet Data Center suggest that some 450 million people in the world use mobile internet.
Stay Up-To-Date
Perhaps the biggest advantage of mobile internet is always having access to the latest facts, figures and information as it happens. This information might range from breaking news delivered by news sites, to stock and shares prices or other business information, to travel updates and the latest weather forecasts in your area. Having up-to-date info allows you to make decisions with all the correct facts at hand.
Find Yourself
Another practical use of mobile internet is to find information regarding the area around you. For example, you might want to find the nearest restaurant, gig or bar and your mobile internet could tell you with a quick look on a search engine. You could then get recommendations and find a map. Many phones also come set up to utilize GPS (Global Positioning System), which uses satellites to locate the phone's user and provide information based on their location. This means the info you obtain using mobile internet can be personalized for you and is thus more helpful, especially if, for example, you are lost on the road and need directions home.
Go Social
With many people now using social networking sites, such as Twitter and Facebook, mobile internet can only make engaging with contacts on these sites easier. In particular, having the net on your cell phone allows you to update your status or check what your friends are up to at the touch of a button---handy for organizing your social life.
Money Matters
Something to consider is the added cost of mobile internet. For some phones, depending upon your phone network or carrier, having your phone enabled for the internet may cost an extra $7 to $10, while a monthly subscription for a smartphone---let's say the Nexus One, for example---might get you unlimited access to the internet, but will also set you back around $79.99 per month.
Privacy Issues
There are privacy issues to consider, too. With more and more people accessing the internet through mobiles, it's easy to forget that five of the major search engines archive the search histories of their users on a regular basis, according to a report from the Center for Democracy & Technology. So individuals may be giving away more information than they realize through their increased net usage.
