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: Real-world speed tests Just how much faster is 4G‚ anyway? We compare Sprint’s 3G and 4G networks. By Brian Nadel December 15‚ 2010 06:00 AM ET22 Comments. What’s this?.Computerworld - Mobile workers who need always-on Internet access -- and who don’t want to rely on public Wi-Fi hot spots -- often turn to a cellular network for connectivity‚ using either a 3G-equipped notebook or an external 3G modem. Now carriers are touting faster fourth-generation wireless networks as the next phase

GSM: Network Architecture The GSM technical specifications define the different entities that form the GSM network by defining their functions and interface requirements. The GSM network can be divided into four main parts: * The Mobile Station (MS). * The Base Station Subsystem (BSS). * The Network and Switching Subsystem (NSS). * The Operation and Support Subsystem (OSS). figure 1: Architecture of the GSM network Mobile Station A Mobile Station consists of two main

QUESTION1 Power Problems Alternating current (AC)‚ which is “food” to PCs and other network devices‚ is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage‚ too much power is coming into the computer. Power overage

Third Generation (3G) and Fourth Generation (4G) are cellular telecommunication networks that supports multimedia and broadband services (Turban & Volonino‚ 2011‚ p. 96). 3G is an evolution of 2G and 4G a successor of the 3G. These network services are sold through telecommunication service providers. Users of these networks can enjoy surfing the Internet‚ checking email and downloading content from the convenience of their mobile devices enabled to use the technology (Gowthami‚ Ramya‚ and Nishanthi
