Long Term Evolution (LTE) technology has brought about a revolution in the field of wireless communications. It has attracted huge attention due to its essential features of being an easily deployable network, offering high data rates and low latencies over long distances. Almost all new cellular and portable communication devices are now LTE enabled. It is also being used as a basis for the upcoming 5G technology and Internet‐of‐Things (IoT) concept, which will allow connectivity anywhere and anytime. It is growing fast to fulfil the ever‐increasing demand from millions of users worldwide with applications ranging from communications to infotainment, healthcare to surveillance and transportation to manufacturing. Sales of LTE‐enabled smart phones alone were expected to grow from 450 million units in 2015 to over 900 million units in 2017.
With huge benefits on offer, the LTE faces challenges of spectrum cognition, interference mitigation and power control. Efficient solutions to these challenges are necessary to enhance the performance of this technology. Femtocells are envisioned as a step forward to smart and low‐interference LTE systems. Moreover, the performance of the overall wireless devices is dictated by the working of embedded antennas. Design of the LTE antennas is getting more complex day‐by‐day due to the advent of new design methodologies, innovative material technologies, miniaturization of devices and performance degradations caused by the user.
The current developments and expected future growth of the LTE demands availability of a comprehensive reference that deals with these systems in the context of femtocells and antennas. This book is an effort to fill this gap by educating the reader on the most important aspects of LTE femtocells and lays the foundations for future advancements. It brings together multidisciplinary contributions in the field of wireless and mobile communications, signal processing and antenna design to identify technical challenges and present recent results related to the development, integration and enhancement of LTE systems in portable devices. Both state‐of‐the‐art and advanced topics including application of cognitive radio with efficient sensing mechanisms, interference mitigation and power management schemes for the LTE systems are discussed. Moreover, a comprehensive account of design challenges and approaches, performance enhancement techniques and effects of a user’s presence on the LTE antennas is presented. Particular focus is put on the promising technologies of multiband, multimode and reconfigurable antennas for efficient design of portable LTE devices. Although the book is intended to be practical, theoretical details are revisited where it is required.
This is the first dedicated book that gives such a broad treatment to LTE systems in the context of femtocells and antenna design, covering wide range of issues related to the topic. The organization of the book makes it a valuable reference for the LTE system designers, as well as an introductory text for researchers, lecturers and students.
