Описание: In this book, three different methods are presented to enhance the capacity and coverage area in LTE-A cellular networks. The scope involves the evaluation of the effect of the RN location in terms of capacity and the determination of the optimum location of the relay that provides maximum achievable data rate for users with limited interference at the cell boundaries. This book presents a new model to enhance both capacity and coverage area in LTE-A cellular network by determining the optimum location for the RN with limited interference. The new model is designed to enhance the capacity of the relay link by employing two antennas in RN. This design enables the relay link to absorb more users at cell edge regions. An algorithm called the Balance Power Algorithm (BPA) is developed to reduce MR power consumption. The book pertains to postgraduate students and researchers in wireless & mobile communications.
Описание: Data communication standards are comprised of two components: The “protocol” and “Signal/data/port specifications for the devices involved”. The protocol describes the format of the message and the meaning of each part of the message. To connect any device to the bus, an external device must be used as an interface which will put the message in a form which fulfills all the electrical specifications of the port. These specifications are called the “Standard”. The most famous such serial communication standard is the RS-232.
In IT technology, Communication can be serial or parallel. Serial communication is used for transmitting data over long distances. It is much cheaper to run the single core cable needed for serial communication over a long distance than the multicore cables that would be needed for parallel communication. It is the same in wireless communication: Serial communication needs one channel while parallel needs multichannel. Serial Communication can also be classified in many other ways, for example synchronous and asynchronous; it can also be classified as simplex, duplex and half duplex.
Because of the wide spread of serial communication from home automation to sensor and controller networks, there is a need for a very large number of serial communication standards and protocols. These have been developed over recent decades and range from the simple to the highly complicated. This large number of protocols was necessary to guarantee the optimum performance for the targeted applications. It is important for communication engineers to have enough knowledge to match the right protocol and standard with the right application. The main aim of this book is to provide the reader with that knowledge.
The book also provides the reader with detailed information about:
The details of each technology including specification, operation, security related matters, and many other topics are covered.
The book allocates three chapters to the main communication standards. These chapters cover everything related to the most famous standard RS-232 and all its variants.
Other protocols such as: I2C, CAN, ZigBee, Z-Wave, Bluetooth, and others, are the subject of the authors separate book “Microcontroller and Smart Home Networks”.
Описание: This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms.Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.
