“…The standard also requires dynamic power control and static and adaptive notching of frequency bands, which renders BB PLC systems cognitive "radios" (which was anticipated by the research community, e.g. [38], [39]). Further standards, namely EN 50561-2 for access networks and EN 50561-3 for frequencies above 30 MHz, are under development.…”

In recent decades, power line communication has attracted considerable attention from the research community and industry, as well as from regulatory and standardization bodies. In this article we provide an overview of both narrowband and broadband systems, covering potential applications, regulatory and standardization efforts and recent research advancements in channel characterization, physical layer performance, medium access and higher layer specifications and evaluations. We also identify areas of current and further study that will enable the continued success of power line communication technology.essentially concerned with coexistence with other systems that also use the power grid (i.e. machines and appliances that draw electricity) and wireless systems operating in the same frequency bands as PLC. The frequency range used for today's PLC solutions starts as low as 125 Hz and reaches as high as 100 MHz. A useful classification of PLC systems according to frequency bands has been introduced in [28]: it distinguishes between ultra-narrowband (UNB), narrowband (NB) and broadband (BB) PLC systems, operating between about 125-3000 Hz, 3-500 kHz and 1.8-100 MHz, respectively. Most recent developments in standardization and regulation activities over the past 20 or so years apply to NB and BB PLC systems, and we will focus on these in the following.

“…If (9) is met, the increment in (11) proceeds. Since there is no way to evaluate the relationship between the target capacity and bandwidth, then the increment previously detailed randomly stops and the device evaluates if with the spectral shaping it is possible to achieve the target capacity.…”

“…So, the problem is to understand actually how much to overlap. 1 Differently from the energy detection approach, here the bandwidth is not updated according to the threshold but simply by performing the algorithm for each value of increment in (11) so that, if it is impossible to shape the signal in a bandwidth since it is occupied, the algorithm move toward different spectrum zones.…”

“…Single carrier approach is not new in the context of such a frequency selective medium [8] and some of the typical problems of this approach deal with InterSymbol Interference (ISI), multi-user interference (if a perfect orthogonal access misses to be implemented); on account of these impairments, the work in [9] introduced a cyclic prefix based scheme for single carrier systems and proposed an equalizer in the frequency domain. Furthermore, in the framework of PLC InHome networking the role played by cognitive paradigm has been explicitly accounted in [10] and [11]. In particular [10] proceeded to propose a cognitive cross-layer algorithm for channel assignment and scheduling in a multi-carrier based access, while [11] proposed a protocol (and compared it with HomePlug v1.0) for channel sensing and power allocation on a multi-carrier scheme.…”

Power Line Communications (PLC) are one of the most recent technologies proposed to allow the InHome Internet access, in competition with different Wireless Standards as Wi-Fi. The advantages offered by PLC deal with network availability since each modem connected to the plug is able, in principle, to access the Internet while in the Wi-Fi scenario, the propagation environment strongly influences the received signal strength and consequently connection performance. The conventional approach followed in planning the physical layer of PLC systems, like for example in HomePlug solution, is based on Orthogonal Frequency Division Multiplexing (OFDM), able to combat the frequency selective nature of the channel frequency response. However, OFDM presents some drawbacks as, for example, Peak to Average Power Ratio (PAPR) and Inter Carrier Interference (ICI) while a different approach based on constrained signal shaping (single carrier) can solve these problems. In this direction, this work shows a frequency shaping approach where the frequency occupancy is minimized through constraints on spectral emission and link quality level. © 2012 IEEE
