During the past years, there has been a quickly rising interest in radio access tech- nologies for providing mobile as well as nomadic and fixed services for voice, video, and data. The difference in design, implementation, and use between TELECOM and datacom technologies is also getting more blurred. One example is cellular technologies from the TELECOM world being used for broadband data and wireless LAN from the datacom world being used for voice over IP.

Duringthe past years, there has been a quickly rising interest in radio access technologies for providing mobile as well as nomadic and fixed services for voice, video, and data. This proves that the difference in design, implementation, and use between TELECOM and datacom technologies is also becoming more blurred. What used to be a mobile phone used for voice communication is today increasingly becoming the main data communication device for end-users, providing web browsing, social networking, and many other services.

Cellular communications is one of the fastest growing and most challenging TELECOM- munication applications ever. Today, it represents a large and continuously increasing percentage of all new telephone subscribers around the world. In the long term, cellular digital technology may become the universal way of communication.

This book is intended to help electric power and telephone company personnel and individuals interested in properly protecting critical tele- communications circuits and equipment located in high voltage (HV) environments and to improve service reliability while maintaining safe working conditions. Critical TELECOMmunications circuits are often located in HV environments such as electric utility power plants, substations, cell sites on power towers, and standalone TELECOMmuni- cations facilities such as 911 call centers and mountaintop TELECOM- munications sites.

Convergence between the two largest networks (TELECOM and IP) is taking place very rapidly and at diff erent levels: (1) network level: unifi cation of IP networks with traditional TELECOM networks through evolving standards (Session Initiation Protocol (SIP), Realtime Transfer Protocol (RTP), SS7, 3G) to support interopera- bility; (2) service level: traditional TELECOM services like voice calls are being provi- sioned on the IP backbone (VoIP), while traditional IP services (most data-driven services such as multimedia, browsing, chatting, gaming, etc.) are accessible over the TELECOM network.

The ability to analyze system or circuit behavior is one of the key requirements for successful design. To put an idea to work, a designer needs both the knowledge and tools for analyzing the behavior of that new system architecture or that experi- mental circuit topology. Design decisions are grounded on the results obtained from analysis.

Long-TermEvolution(LTE)isarguablyoneofthemostimportantstepsinthecurrentphaseof the development of modern mobile communications. It provides a suitable base for enhanced services due to increased data throughput and lower latency figures, and also gives extra impetus to the modernization of TELECOM architectures. The decision to leave the circuit- switched domainoutofthescope ofLTE/SAEsystem standardization might soundradical but itindicatesthattheTELECOMworldisgoingstronglyfortheall-IPconcept----andthedeployment of LTE/SAE is concrete evidence of this global trend.

Changes in TELECOMmunications are impacting all types of user group, which include business users, traveling users, small and home offices, and residential users. The acceptance rate of TELECOM- munications and information services is accelerating significantly. Voice services needed approximately 50 years to reach a very high teledensity; television needed just 15 years to change the culture and lives of many families; the Internet and its related services have been penetrating and changing business practices and private com- munications over the last 2 to 3 years.

Today wireless is becoming the leader in communication choices among users. It is not anymore a backup solution for nomadic travellers but really a newmoodnaturallyusedeverywhereevenwhenthewiredcommunicationsare possible. Many technologies evolve then continuously, changing the TELECOM- munication world. We talk about wireless local area networks (WLANs), wire- less personal area networks (WPANs), wireless metropolitan area networks (WMANs), wireless wide area networks (WWANs), mobile ad hoc networks (MANETs), wireless sensor networks (WSNs) and mesh networks. Since we can find today a multitude of wireless technologies we decided to group a numberofcomplementarytechnologiesintoonedocumenttomakeiteasierfor areadertounderstandsomeofthetechnicaldetailsofeachmedia.
