Wired and Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference

1. Introduction The increasing interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications

Wireless Network Security Partha Dasgupta and Tom Boyd Dept. of Computer Science and Engineering Fulton School of Engineering Arizona State University partha@asu.edu‚ tboyd@asu.edu Abstract Wireless networking is inherently insecure. From jamming to eavesdropping‚ from man-inthe middle to spoofing‚ there are a variety of attack methods that can be used against the users of wireless networks. Modern wireless data networks use a variety of cryptographic techniques such as encryption and authentication

3G vs 4G There has been more talk about 4G (fourth generation) mobile broadband recently and Nokia Siemens Networks (NSN’s) has announced that the first 4G field trials have been completed in Berlin. As 4G seems to have taken a step closer to reality‚ I decided to do some research and find out what advantages 4G may offer over 3G. The specifications for 4G are not standardized yet but the following 3G vs 4G table gives an idea of what 4G is likely to provide. Technology | 3G | 4G | Frequency

for the large wireless mobile providers you’ll most likely hear about how their networks run on 4G and the ads make it sound like 4G is the greatest thing to happen to mobile devices‚ including cell phones and tablets. But is 4G really better then 3G or is it a lot of hype to get you to sign a new contract? Let’s examine the two systems. The G in 3G and 4G (and earlier versions) stands for "Generation"‚ which is really the generation of tech installed on your phone and at the wireless towers. As new
