Wireless and Mobile Networking
by Mahbub HassanThere has been phenomenal uptake of wireless and mobile networking technologies in the past decades. Significant developments have taken place during this time making the wireless technology more affordable, effective, and reliable. This book explains the fundamental principles and protocols of key existing and emerging wireless networking technologies. The book begins with a review of the fundamentals of wireless communications. It covers the basic theories and terminologies of coding and modulation, which maps digital information to the underlying signal, as well as the models to capture the dynamics of wireless signal propagation in the environment. It provides in-depth coverage of the WiFi evolution covering both the mainstream WiFi, which operates in 2.4/5GHz with new versions targeting 6GHz, as well as some of the niche WiFi standards that operate outside the mainstream bands such as 802.11af in 700MHz TV bands, 802.11ah in 900MHz to connect the Internet of Things (IoT), and 802.11ad/ay in 60GHz to support multi-gigabit applications. The book covers the fundamental concepts of cellular networks, examines the advancements brought forth by each generation, and discusses new applications and the underpinning wireless technologies promised by 5G. It also covers a recently developed long-range low-power wireless networking technology called LoRa, which is the fastest growing technology to connect millions of IoT sensors and devices throughout the world. The concluding chapters examine emerging wireless paradigms such as Artificial Intelligence for wireless networking, sensing with wireless signals, and mobile networking with flying base stations carried by drones and unmanned aerial vehicles (UAVs). With many worked-out examples, illustrative figures, and multiple choice questions, this book is an ideal for students and a valuable reference for anyone working in this rapidly evolving field.

by Zoubir MammeriResearch and development in wireless and mobile networks and services areas have been going on for some time, reaching the stage of products. Graceful evo- tion of networks, new access schemes, flexible protocols, increased variety of services and applications, networks reliability and availability, security, are some of the present and future challenges that have to be met. MWCN (Mobile and Wireless Communications Networks) and PWC (Personal Wireless Communications) are two conferences sponsored by IFIP WG 6.8 that provide forum for discussion between researchers, practitioners and students interested in new developments in mobile and wireless networks, services, applications and computing. In 2008, MWCN and PWC were held in Toulouse, France, from September 30 to October 2, 2008. MWNC’2008 and PWC’2008 were coupled to form the first edition of IFIP Wireless and Mobile Networking Conference (WMNC’2008). MWCN and PWC topics were revisited in order to make them complementary and covering together the main hot issues in wireless and mobile networks, services, applications, computing, and technologies.
Wireless and Mobile Networking: Second IFIP WG 6.8 Joint Conference, WMNC 2009, Gdansk, Poland, September 9-11, 2009, Proceedings (IFIP Advances in Information and Communication Technology #308)
by Jozef Wozniak Jerzy Konorski Ryszard Katulski Andrzej R. PachRecent spectacular achievements in wireless, mobile, and sensor networks have dramatically changed our lives in many ways. However, the rapid evolution of wireless systems not only promises increased functionality, reliability, availability, and security, as well as putting a wide variety of new services at the users’ disposal ? it also creates a number of design challenges that our research community is now facing. Scientists and engineers need to come up with, and promptly implement, novel wireless network architectures, while system operators and planners rethink their business models and attend to the growing expectations of their customer base. To provide a suitable forum for discussion between researchers, practitioners, and industry representatives interested in new developments in the respective research area, IFIP WG 6. 8 launched three separate series of conferences: MWCN (Mobile and Wireless Communications Networks), PWC (Personal Wireless Communications), and WSAN (Wireless Sensor and Actors Networks). In 2008, MWCN and PWC were merged into the IFIP Wireless and Mobile Networking Conference (WMNC 2008), held in Toulouse, France, from September 30 to October 2, 2008. MWNC 2008 and PWC 2008 topics were subsequently revised with a view to covering the whole spectrum of hot issues in wireless and mobile networking. As a result, IFIP WG 6. 8 decided to add WSAN as another WMNC track.

Wireless CMOS Frequency Synthesizer Design (The Springer International Series in Engineering and Computer Science #439)
by J. Craninckx Michiel SteyaertThe recent boom in the mobile telecommunication market has trapped the interest of almost all electronic and communication companies worldwide. New applications arise every day, more and more countries are covered by digital cellular systems and the competition between the several providers has caused prices to drop rapidly. The creation of this essentially new market would not have been possible without the ap pearance of smalI, low-power, high-performant and certainly low-cost mobile termi nals. The evolution in microelectronics has played a dominant role in this by creating digital signal processing (DSP) chips with more and more computing power and com bining the discrete components of the RF front-end on a few ICs. This work is situated in this last area, i. e. the study of the full integration of the RF transceiver on a single die. Furthermore, in order to be compatible with the digital processing technology, a standard CMOS process without tuning, trimming or post-processing steps must be used. This should flatten the road towards the ultimate goal: the single chip mobile phone. The local oscillator (LO) frequency synthesizer poses some major problems for integration and is the subject of this work. The first, and also the largest, part of this text discusses the design of the Voltage Controlled Oscillator (VCO). The general phase noise theory of LC-oscillators is pre sented, and the concept of effective resistance and capacitance is introduced to char acterize and compare the performance of different LC-tanks.

Wireless Communication in Underground Mines: RFID-based Sensor Networking
by L. K. Bandyopadhyay S. K. Chaulya P. K. MishraWireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.
Wireless Communication Technologies: New MultiMedia Systems (The Springer International Series in Engineering and Computer Science #564)
by Norihiko Morinaga Ryuji Kohno Seiichi SampeiDuring 12-15 of September 1999, 10th International Symposium on P- sonal, Indoor and Mobile Radio Communications (PIMRC’99) was held in Osaka Japan, and it was really a successful symposium that accommodated more than 600 participants from more than 30 countries and regions. PIMRC is really well organized annual symposium for wireless multimedia commu- cation systems, in which, various up-to-date topics are discussed in the invited talk, panel discussions and tutorial sessions. One of the unique features of the PIMRC is that PIMRC is continuing to publish, from Kluwer Academic Publishers since 1997, a book that collects the hottest topics discussed in PIMRC. In PIMRC’97, Invited talks were sum- rized in “Wireless Communications –TDMA versus CDMA – (ISBN 0-7923- 8005-3),” and it was published just beforePIMRC’97. This book was also distributed to all the PIMRC’97 participants as a part of proceedings for the conference. In PIMRC’98, extendedversion of the invited papers were s- marized in Wireless Multimedia Network Technologies (ISBN 0-7923-8633- 7) and published in September 1999, which is almost the same timing for the PIMRC’99. In the case of PIMRC’99, to produce more informative book, we have - lected topics that attracted many PIMRC’99 participants during the conf- ence, and invited prospective authors not only from the invited speakers but also from tutorial speakers, panel organizers, panelists, and some other exc- lent PIMRC’99 participants.

Wireless Communications: TDMA versus CDMA
by Savo G. Glisic Pentti A. LeppänenIn Time Division Multiple Access (TDMA), within a given time frame a particular user is allowed to transmit within a given time slot. This technique is used in most of the second-generation digital mobile communication systems. In Europe the system is known as GSM, in USA as DAMPS and in Japan as MPT. In Code Division Multiple Access (CDMA) every user is using a distinct code so that it can occupy the same frequency bandwidth at the same time with other users and still can be separated on the basis of low correlation between the codes. These systems like IS-95 in the USA are also developed and standardized within the second generation of the mobile communication systems. CDMA systems within a cellular network can provide higher capacity and for this reason they become more and more attractive. At this moment it seems that both TDMA and CDMA remain viable candidates for application in future systems. Wireless Communications: TDMA versus CDMA provides enough information for correct understanding of the arguments in favour of one or other multiple access technique. The final decision about which of the two techniques should be employed will depend not only on technical arguments but also on the amount of new investments needed and compatibility with previous systems and their infrastructures. Wireless Communications: TDMA versus CDMA comprises a collection of specially written contributions from the most prominent specialists in wireless communications in the world today and presents the major, up to date, issues in this field. The material is grouped into four chapters: Communication theory, covering coding and modulation, Wireless communications, Antenna & Propagation and Advanced Systems & Technology. The book describes clearly the issues and presents the information in such a way that informed decisions about third generation wireless systems can be taken. It is essential reading for all researchers, engineers and managers working in the field of Wireless Communications.
Wireless Communications 2007 CNIT Thyrrenian Symposium (Signals and Communication Technology)
by Silvano PupolinThe 18th Tyrrhenian Workshop on digital communications is devoted to wi- less communications. In the last decade, wireless communications research boosted launching new standards and proposing new techniques for the - cess technology. We moved from the UTRA standard capable to transmit 0. 5bit/s/Hz to WLAN which is promising 2. 7bit/s/Hz. Now wireless c- munication systems are facing a ?ourishing of new proposal moving from multiple antennas at transmitter and receiver side (MIMO systems), to new powerfulForwardErrorCorrectionCodes,toadaptiveradioresourcemana- mentalgorithms. Thenewchallenge,however,isthemovetowardsmultimedia communications and IP technology. This move implies e?orts in several new aspects. First of all an open network, as IP is, imposes the necessity of a - cure network, to guarantee the privacy of the ongoing communications, avoid the use of the networks by unauthorized customers, avoid the misuses and the charge to third parties of the cost of the connection. Also, quality of service (QoS) of the communications is becoming a must in IP networks which are carrying services which need a guaranteed QoS as telephony, real time s- vices, etc. To get this new target some form of access control to the network must be setup. Recently, new form of communication networks has appeared to collect data for several applications (sensor networks, ad hoc networks, etc. ) and they need a connection with a backbone network which could be a wireless one with a larger range than the sensor or ad hoc networks.
