  • Introduction

    This chapter contains sections titled:Network ArchitectureRadio Access TechnologyStandardisation

  • Modulation and Demodulation

    This chapter discusses common types of modulation and their variants. It explores the spectral effects of modulation and explains why certain types of modulation are used in differing situations. The chapter also explains, using mathematical notation, the operation of modulators and demodulators. It provides block diagrams of modulators and demodulators, both analog and digital, and derives the mathematical expressions for their form where appropriate. The chapter then discusses notion of phase lock and the phase‐locked loop (PLL) and Costas loops. It demonstrates the operation of multibit digital modulation using quadrature amplitude modulation (QAM) and quadrature phase shift keying (QPSK). The chapter helps the reader to understand the use of advanced modulation techniques, such as orthogonal frequency division multiplexing (OFDM), for increased digital bit rate; and spread‐spectrum (SS) techniques: direct‐sequence SS and frequency‐hopping SS.

  • Limitations to Radio Frequency Human Exposure

    Populations are exposed to electromagnetic fields (EMF), the levels of which continue to increase due to more wireless systems (such as Wi‐Fi) and as technology advances, for example, LTE operation may increase the human exposure by 20%. Limitations to Radio Frequency (RF) human exposure contain restrictions on exposure that are intended to assist those with responsibility for the safety of the general public and workers. This chapter discusses a specialist area; it is of significance to spectrum managers and policy‐makers, as stringent policies, regulations and approaches affect the provision of radio services. There are countless studies on EMF risks; the chapter focuses on policies and regulations without entering the biological arena. The national limitations on radio frequency human exposure are becoming more stringent, due to societal concerns and electromagnetic hypersensitivity. Municipalities and national administrations are striving to lower thresholds. The globalization and harmonization may lead to the adoption of the universal levels of ICNIRP.

  • Model Predictive Control of Impedance Source Inverter

    The control strategy of the power converter plays a crucial role in ensuring reliable and efficient operation of renewable based distributed generation (DG) systems. In most applications, proportional-integral (PI) based cascaded control structures have been used to control current, voltage, etc. To eliminate the drawbacks of the cascaded control structure and difficulties of the modulation techniques, this chapter examines the model predictive control (MPC) technique for impedance source - Z-source (ZS) and quasi-Z-source (qZS) - three-leg, four-leg, and multiphase inverters. Then, it presents ZS/qZS three-phase three-leg, four-leg, and multiphase (five-phase) inverter topologies, along with a description of the topology, model, and switching schemes for control. After that, the MPC algorithm for ZS/qZS three-phase, three-leg, four-leg, and multiphase (five-phase) inverters are presented. Finally, to prove the addressed MPC strategy, a performance investigation has been carried out with qZS four-leg inverter and simulation results are presented to demonstrate the capabilities of the MPC.

  • National Spectrum Management

    The national radio frequency (RF) spectrum is regulated by a fixed and wireless telecommunications ministry or national agency. The National Spectrum Management (NSM) offers the radio spectrum for both government and non‐government use to stimulate social and economic progress, to achieve an efficient and effective use of the spectrum. The responsible spectrum management ministry or agency may be structured in different ways according to the law, customs and telecommunication resources of the country concerned. The spectrum management structure is naturally formed around the functions that it must perform. Regulators typically address interference concerns solely through regulations on transmitters, despite the fact that the receivers are interfered; interference is determined by both transmitter and receiver. In order to overcome linguistic barriers, the RF spectrum management and licensing of France can serve francophone countries, while the UK and US regulations are advantageous to English‐speaking countries.

  • Wireless Communications Blocks Integration

    This chapter looks at top level view of wireless communication systems, reviews 4G standards, and integrates each wireless communication block. The International Standard Organisation (ISO) has defined the Open Systems Interconnection (OSI) 7 layer model for network protocols. The advantage of the OSI 7 layer model is that each layer is regarded as a black box and one layer transfers the input/output to another layer above/below the layer. There have always been technology competitions to meet the requirements and secure a share of the new market. The chapter takes a look at two technology camps: Long‐Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX) and compares their physical layer technologies. The LTE physical layer is similar to the WiMAX physical layer. Their key physical layer technologies include MIMO, OFDMA, AMC, Turbo code, and so on. The chapter concludes with a note on System‐on‐Chip (SoC) design for a WiMAX handset.

  • Coordinated Multipoint Transmission and Reception

    None

  • Short Range Devices and the License‐Exempt RF Spectrum

    Short range devices (SRDs) include radio transmitters, providing either unidirectional or bi‐directional communication, which do not cause a lot of interference for other radio equipment. The regulatory framework for SRDs, such as the decision on frequency bands that SRDs can use, is a national matter. SRDs in general operate in shared bands and are not permitted to cause harmful interference to radio services. In general, SRDs cannot claim protection from radio services, another intentional or unintentional radiator, industrial, scientific and medical (ISM) equipment, or an incidental radiator. Conventional cellular technology and Wi‐Fi technology converge: converged phones can switch between conventional cellular and Wi‐Fi voice‐over‐internet‐protocol (VoIP) modes. The three case studies depicted in the three International Telecommunication Union (ITU) Regions show the differences in SRDs’ RF bands, power, channel spacing, duty cycle and interference mitigation requirements. The main RFID's applications are asset management, cutting tools in computer numerical control (CNC) systems, and waste bin identification.

  • Air Interface Concepts

    This chapter covers the radio aspects of long term evolution (LTE), starting with an overview of the radio frequency (RF) specifications. The chapter highlights those aspects of the LTE RF requirements that will be new compared to universal mobile telephone system (UMTS). These include issues relating to LTE's support of multiple bands and channel bandwidths as well as those RF specifications peculiar to the use of orthogonal frequency division multiple access (OFDMA) modulation on the downlink and single‐carrier frequency division multiple access (SC‐FDMA) on the uplink. The chapter describes the multi‐antenna mechanisms adopted by LTE to increase coverage and physical layer capacity. It focuses on the air interface as many of the operational details of the system are left to the designers of the evolved node B (eNB).
