With most wireless kits they make sure the network setup process is easy, no matter what your level of experience. The installation software automatically sets up everything without making you deal with network setup screens. The downside to wireless is its speed is only about 1-2 megabits per second. As you can see, it's considerably slower than the 100 megabits per second wired network. Wireless is definitely not optimum for network game playing or exchanging huge files.

Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox). Cellular ... ... middle of paper ... ... software in terms of the device contains the small computer chip with the Bluetooth on it but it needs software to connect to via Bluetooth. All types of technology ranging from medical and health devices like sensors to smartphones, PCs and tablets use Bluetooth technology which makes lives easier and efficient. Without wireless technology people would be tied to one location where they can access internet.

This will allow us to gain a more fundamental insight in the possibilities and restrictions of wireless LAN. Generally, wireless LAN proved to be a reliable and reasonably fast mobile networking solution. For most purposes, the bandwidth it provides should suffice, although cabled LANs offer more possibilities to extend the bandwidth. In situations where mobility is as good a criterion as bandwidth, a wireless LAN should certainly be considered a serious option.

It is expected that the price of wireless networking interface cards to become inexpensive like the Ethernet cards. If your computer is connected to a wireless LAN, you can communicate to a wired LAN. You would need some sort of bridge between the wired and wireless LAN. You would need hardware or software based access point. Hardware access points are available with various types of network interfaces such a... ... middle of paper ... ...d, much less decoded, by simple scanners, short wave receivers etc.

So, it is important to secure the wireless network by utilizing small time to be saved in future. The security of wireless networks becomes more vital because it is most commonly used in every field. There are number of practices developed for securing wireless networks till now and because of the scope, and its importance, more research is being done for more secure wireless networks in future ( Solms, BV & Marais, E 2004). Wireless Network Security 1. Wireless Networking Basics According to (Vacca, JR 2006) The term wireless networking means the technology that facilitates two or more computers to communicate using standard network protocols, but without network cabling.

This enhances usability and in some sense, creativity. Wireless internet isn’t really that hard to setup. You need an access point, a server, and a laptop. After that, it’s all a matter of configurations and you’re in. The only real complaint that we heard about Wi-Fi is that there are security issues.

This is possible because of as previously explained, WiFi radios are a two way system being able to both transmit and receive. Doing this will convert your phones receiving LTE or 3G data packets into the transmission of WiFi signal. A wireless router is what uses an antenna to send signals to wireless devices and a wire to send signals to the Internet. Five ... ... middle of paper ... ...ve multiple walls in the way of two devices communication with Bluetooth and it usually will not be an issue. One con to mention though would be the lack of security.

These networks are cost effective in that they are able to connect remote users to the corporate network without the need for expensive dedicate WAN links or modem banks. They also allow remote users to utilize their own internet connections from their remote site which also saves the corporation money. In essence, the longer the distance is between the connections, the more savings the company can realize. Increased security is also a factor in that it provides encryption between the two sites and that helps protect against unauthorized access to the system. The system is also scalable in that additional hardware is easily added to the network to allow for more users.

Technologies happens to be speeding up to the society we currently live in. Bluetooth technologies is a short-range communications technologies that's easy, safe, and everywhere. You can discover it in billions of devices ranging from mobile phones and computers to medical devices and home entertainment goods. It's intended to replace the cables connecting devices, while sustaining higher levels of safety. The key attributes of Bluetooth technology are robustness, low power, and low price.

This also leads to the usage of wireless networks being used as a backup. It would be much easier to connect the disconnected users to the network if they were already set up with the proper wireless networking software and hardware prior to the problem. Therefore, being used as a backup is very useful especially in buildings where the architecture makes it difficult to find and repair broken cables. Another reason wireless is needed is because there are some places where cables just can not reach. This may be the case in many businesses where cables can not be run across roads, long distances, or to mobile users.
