A defining characteristic of the mobile wireless channel is the variations of the channel strength over time and over frequency. The variations can be roughly divided into two types (Figure 2.1): • Large-scale fading, due to path loss of signal as a function of distance and shadowing by large objects such as buildings and hills. This occurs a The full Duplex communication system is also two-way communication & it is simultaneous. The best example of this communication system is the mobile phone. In wireless communication, the devices which are used for communication may change from one service to others because these are available in different shape, size & data throughput Mobile communication protocols use multiplexing to send information. Multiplexing is a method to combine multiple digital or analog signals into one signal over the data channel. This ensures optimum utilization of expensive resource and time. At the destination these signals are de-multiplexed to recover individual signals Explore Summer 2006 3G Mobile Communication Networks 6 3G Mobile Communication Networks Back Ground Third generation (3G) is the generic term used for the next generation of mobile communications systems.

Introduction to Mobile Communication. Mobile Communication is the use of technology that allows us to communicate with others in different locations without the use of any physical connection (wires or cables). Mobile communication makes our life easier, and it saves time and effort. A mobile phone (also called mobile cellular network, cell phone or hand phone) is an example of mobile. 2.2 GSM (Global System for Mobile Communications) GSM is a second generation digital cellular system. Digital transmission was used rather than analog transmission in order to improve transmission quality, system capacity, and coverage area. GSM works on three frequencies 900 MHz, 1800 MHz an

Very often, especially in mobile communications, not only do multiple propagation paths exist, but they are also time-varying. The result is a time-varying fading channel. Communication through these channels can be difficult. Special techniques may be required to achieve satisfactory performance. A.

Introduction to GSM Technologies. GSM or Global System for Mobile Communications is the most popular wireless cellular communication technique, used for public communication. The GSM standard was developed for setting protocols for second generation (2G) digital cellular networks. It initially started as a circuit switching network, but later packet switching was implemented after integration. data from consumers and industrial users. Fifth-generation (5G) mobile technologies represent the next iteration of mobile communications technologies that were designed to improve current (e.g., 3G, 4G) mobile networks. 5G networks are expected to provide faster speeds, greater capacity, and the potential to support new features and services Mobile device Mobile, wireless or cellular phone - a portable, handheld communications device connected to a wireless network that allows users to make voice calls, send text messages and run applications.

Mobile phones share many of the vulnerabilities of PCs. However, the attributes that make mobile phones easy to carry, use, and modify open them to a range of attacks. • Perhaps most simply, the very portability of mobile phones and PDAs makes them easy to steal. The owner of a stolen phone could lose all the data stored on it, from persona LMSS enables a mobile link between the communication earth system and the vehicle's earth system or two or more vehicles' earth stations or two MSC stations.
