communications (PLC) is a global technology with worldwide interest in its development. In its simplest terms‚ PLC modulates communication signals over existing power lines. This enables devices to be networked without introducing any new wires or cables. This capability is extremely attractive across a diverse range of applications that can leverage greater intelligence and efficiency through networking.” - Texas Instruments. Introduction: Let me start with a question and provide you a relevant

data collision. However‚ Token Ring Networks‚ can also process data remarkably slower than Ethernet Architecture (sometimes as slow as 4 or 16 Mbps). Ethernet‚ by design are typically used in office buildings that are wired with twisted pair CAT-5 cables‚ or fiber optic cables for fast transmission of data‚ with each employee location fitted with an Ethernet jack to connect to the network. Utilizing this type of Architecture‚ if a problem arises in network

Quadrature amplitude modulation (QAM) ([pic] /ˈkwɑːm/ or /ˈkæm/ or simply "Q-A-M") is both an analog and a digital modulation scheme. It conveys two analog message signals‚ or two digital bit streams‚ by changing (modulating) the amplitudes of two carrier waves‚ using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme. The two carrier waves‚ usually sinusoids‚ are out of phase with each other by 90° and are thus called quadrature carriers

simple home setup that anyone could do. The start of this network is the Internet connection‚ which would be a cable connection. The service provider would be from the cable company and would use a coaxial cable from the wall connected to a modem device usually provided by the installing cable company. The Zoom CableModem 5241 would be the choice for the modem and is what is used by most cable companies. The modem will be located next to the main computer of the household for ease of access by the administrator

MODBUS RS485 Twisted Wire Pair NET Concentrator System Station #1 Another advantage of MODBUS is that it can run over virtually all communication media‚ including twisted pair wires‚ wireless‚ fiber optics‚ Ethernet‚ telephone modems‚ cell phones and microwave. This means that a MODBUS connection can be established in a new or existing plant fairly easily. In fact‚ one growing application for MODBUS is providing digital communications in older plants‚ using existing twisted pair wiring.

As per Wikipedia‚ "natural monopoly" is defined as "an industry is said to be a natural monopoly if one firm can produce a desired output at a lower social cost than two or more firmsthat is‚ there are economies of scale in social costs. Unlike in the ordinary understanding of a monopoly‚ a natural monopoly situation does not mean that only one firm is providing a particular kind of good or service. Rather it is the assertion about an industry‚ that multiple firms providing a good or service is
