  • Coupling

    This chapter considers coupling of power line communication (PLC) signals to and from low voltage (LV), medium voltage (MV) and high voltage (HV) power lines. Since narrowband PLC (N‐PLC) has the wider percentage bandwidth and more severe mains rejection requirement, that frequency range is used for the coupler designs. For broadband PLC (B‐PLC) designs, the coupling networks can easily be changed in frequency and mains rejection, to cover B‐PLC operation. In practice the LV line impedance at both N‐PLC and B‐PLC frequencies changes over time, as consumers switch devices on and off. Circuits for passing PLC signals allow for many LV PLC modems to communicate with modems operated by electricity suppliers on the MV network. The chapter also describes how these principles are applied to specific market areas, such as LV Smart Grid and Power line Local Area Network (LAN) applications and MV and HV protection and switching circuits.

  • The Family of DSL Technologies

    Asymmetric digital subscriber line (ADSL) and later very high bit rate DSL (VDSL) were designed to transport higher bit rates downstream than upstream. ADSL and VDSL standards specify the ability to greatly reduce the transmitted power in narrow‐frequency bands used for amateur radio (HAM) transmission; this is known as RFI notching. As with all forms of DSL, the performance of ADSL technology varies greatly depending on the length of the line, wire gage, crosstalk noise, and other impairments such as bridged taps. Work on VDSL started in the T1E1.4 and ETSI TM6 standards groups in 1994. The basic concept was to apply ADSL techniques to a wider frequency band, so that much higher bit rates could be transmitted downstream and upstream. Recently, a new generation of DSL technology has been defined to transmit data between a customer premises and a network node up to 250 meters from the home.

  • 3GPP Mobile Communications: GSM

    This chapter describes the architecture, core and radio systems of global system for mobile communications (GSM). The GSM network consists of the network and switching subsystem (NSS), the base station subsystem (BSS), and the operations subsystem (OSS), which controls the functioning of the NSS and the BSS. 3rd Generation Partnership Project (3GPP's) organization consists of a project coordination group (PCG) and five technical specification groups (TSG). The chapter includes essential information about the interfaces, elements, modulation, coding, modes, functionality and performance of the system, as well as frequencies, terminals, planning, dimensioning and optimization of radio, transport and core networks. It presents practical use cases. There are also modern functionalities presented to optimize the capacity and interference levels of GSM as one part of the refarming strategies, and information about the advanced data and signaling methods which can be utilized until the end of the useful lifecycle of GSM networks.

  • Medium Access Control and Layers Above in PLC

    Power lines provide a shared communication channel so that medium access control (MAC) and protocols that reside above the physical layer have to be implemented. This chapter describes such protocols, summarizes the MAC principles and considers a power line communication (PLC) network organized in multiple cells. In such a scenario, media access schemes and resource sharing strategies among the cells for broadband PLC are discussed. The problem of allocating resources in a single cell multiple‐user network is considered. The achievable rate of the multiple‐access and the broadcast channel is discussed considering both time division multiple access (TDMA) and frequency division multiple access (FDMA). The resource allocation problem is addressed for the specific PLC channel that exhibits a periodically time variant response with cyclostationary noise. Finally, the chapter presents usage of cooperative communication mechanisms, such mechanisms can be implemented through a tight connection with the physical layer.

  • Advanced DSL Techniques and Home Networking

    The use of repeaters diminished greatly as modern DSL and fiber technology became prevalent. The use of repeaters has become relatively rare, but the use of multi‐pair bonding is growing, because bonding avoids most of the drawbacks of repeaters. Dynamic spectrum management (DSM) introduces the concept of a spectrum management center (SMC). The SMC is a central management system that has knowledge of most or all of the lines in the cable, and it is aware of the service attributes for each line. Vectoring is a technique to reduce the effects of the crosstalk between DSLs operating in the same cable. DSL vectoring may consist of receiver‐based noise cancellation techniques and transmitter‐based precoding techniques. Femtocell wireless technology is a way to extend the benefits of broadband access throughout the home or business.

    A smartphone contains several components including processors. It incorporates the functionalities of a handheld computer to run different user applications along with the functionalities of a cellphone modem. This chapter shows the different modules of a smartphone and lists different hardware components. It discusses these components in more details. The baseband part is responsible for a cellular system's modem bit detection, bit transmission, protocol processing, sleep and power management, audio processing, and so forth, and the application part is responsible for running different applications. The baseband modem manages radio communications, signal processing tasks, and protocol stack to enable the smartphone to access different types of wireless network technologies. The application unit relies mainly on a general purpose processor (GPP), most commonly a reduced instruction set computers (RISC) processor, which provides the processing needed by the applications and provides user interfaces and overall command‐and‐control functions.

  • Cellular Systems Modems

    A modem is an electronic device that helps to modulate and demodulate the information at the transmitter and receiver block respectively in order to transmit the information signal reliably through the propagating medium. Initially a modem was also known as 'data phone', as it enabled a computer terminal (host) to send and receive information over public switched telecommunications networks (PSTNs) by converting the digital data of a computer terminal into an analog signal used on telephone phone lines and then converting it back to its original form once it was received at the other end. These modems are commonly known as 'dialup modems'. Wireless modems work in the same way as a dialup analog modem, except they convert digital data into radio signals for transmission through air. This chapter discusses how the cellular systems including mobile phone modem system has been evolved over several generations and also discusses the legacy modems.

  • DSL Standards

    ANSI standard T1.417 (now known as ATIS‐0600417.2003) was originally published in 2001, specifying spectrum management guidelines for DSL transmission on telephone lines. This standard was developed by standards working group T1E1.4. The purpose of the T1.417 DSL spectrum management standard is to set a limit on the interference produced by DSL modem crosstalk. The success of DSL technology has led to a vast number of alternative modes and options. ITU‐T Rec. G.994.1 specifies a set of parameters describing all standard DSL modes and options. Ethernet‐based bonding is specified in ITU‐T G.998.2, which is nearly identical to the ATIS T1.427.02 standard, and these were both derived from the earlier IEEE 802.3ah standard. ITU‐T Recommendation G.996.1 provides a common, defined set of twisted‐pair line characteristics, inhome wiring models, and noise models to be used for performance testing of DSL modems.
