The evolution of transmission media has come a long way since it was first introduced many years ago. Media selection is often affected by the network standards that you want to implement. The type of media required for specific devices is dependent on the network hardware. The two main types of transmission media include: cable and free space. Cable had long been the commonly implemented media for data transmission (telephone, television, Computers). Even Though the current trend is towards wireless implementations, cable is generally still needed for backbones and certain types of networks. The three basic types of cables are:
Twisted pair.
Coaxial.
Fiber optic.
One of the basic ways to get started was a dial-up connection internet, which has been around since the 1980’s. Dial-up internet access may be used where other forms are not available or the cost is too high, as in rural or very remote areas.
This brings us to Twisted-pair cables, which would fall under one of the four categories
Category 1- Traditional telephone cable, not designed for data. Supports low speed communication, such as dial-up lines
Category 2- Contains two-twisted pair of cables and supports data transmission and supports up to 4Mbps
Category 3- contains four twisted pair of cable and supports up to 16Mbps
Category 4- contains four twisted pair of cable and supports up to 20Mbps

As Technology grew, the networking system had to also grow along with it. Network Cables would have to be updated and DSL and Broadband would come into the picture. Updating how we use the internet today, now most everything is wireless mostly free-space which would include these types
Infrared
Short-range wireless
Microwave
Satellite
Televisions, cell phones, computers and laptops any place you look are going wireless. There are some who wish to stick with DSL considering the fact that it runs over phone lines using coaxial line. Although it uses a phone line in a manner similar to dial-up it is much, much faster, plus it is a dedicated line to the ISP with access to broadband speeds. DLS Broadband is also much cheaper than wireless, and somewhat more reliable.
Wireless depending on what you are using a wireless connection for can be much faster a bit more expensive, but in personal experience using satellite television and internet in bad weather can interfere with the signal and disrupt your services, which can be frustrating especially if you are trying to work, or do homework. Eventually everything will wireless or even more advanced than that, but Networking will always need some kind of backbone to function and be reliable.

It Notes

...Chapter 3: Transmission Basics and networking media Transmission Basics Transmit: to issue signals along a network medium such as a cable. Transmission: Refers to either the process of transmitting or the progress of signals after they have been transmitted. * Analog and Digital Signaling: * On a data network, information can be transmitted via one of two signaling methods, analog or digital. * Voltage: the strength of an electrical signal * Analog: * One benefit to analog signals is that, because they are more variable than digital signals, they can convey greater subtleties with less energy. * One drawback to analog signals is that their voltage is varied and imprecise. Thus, analog transmission is more susceptible to transmission flaws such as noise, or any type of interference that may degrade a signal, than digital signals. * Digital: Composed of pulses of precise, positive voltages and zero voltages. A pulse of positive voltage represents a 1, a pulse of zero voltage represents a 0. * Continuous * Amplitude: Waves amplitude is a measure of its strength at any given point in time. The amplitude is the height of the wave at any point in time. * for example, the wave has an amplitude of 5 volts at .25 seconds, an amplitude of 0 volts at .5 seconds, and an amplitude of -5 volts at .75 seconds. * Frequency: the number of times that a waves amplitude cycles from its starting point, through its highest amplitude and its...

The Favored Resolution Package The truly pressing conundrum that requires resolving is the present network capacity that prevails at just 10 Mb. The favored resolution here is Category 6 UTP 1000Base F Ethernet cabling because it boosts the greatest data transmission rate a hundredfold from 10 Mb to 1 gigabyte per second. Such bandwidth addresses the objectives of the HVAC technician for remote access to his devices. Even more significant, such a transmission rate unclutters the congestion faced when the seven networked classrooms concurrently dispatch attendance records and access personal emails early in the morning and 23 more classrooms require addition to the network. Finally, the advantage of a fiber optic backbone is that the remote location of the mail server becomes irrelevant. The ideal solution ought to create provisions for collecting all the servers, including the printer servers, for comfort of maintenance and diagnostics. Using...

Network Topologies

...backbone networks. Partial mesh topology is less expensive to implement and yields less redundancy than. With partial mash some nods are organized in a full mesh team but others are only connected to one or two in the network. Partial mashed apology is commonly found in peripheral networks connected to a full mesh backbone. Bus Topology; the bus apology is the simplest network topology. Also known as linear bus, and all this topology all computers are connected to a contiguous cable or a cable joined together to make it contiguous. Ethernet is the common example of a bus topology. Each computer determines when the network is not busy and transmits data as needed. Computers in a bus apology listen only for transmission from other computers; they do not repeat or forward the transmission on the other computers. The signal in a bus topology travels to both ends of the cable. To keep the signal from bouncing back and forth along the cable, both ends of the cable in a bus topology must be terminated. A component called a Terminator, essentially nothing more than a resistor, is placed on both ends of the copper (coax) cable. The terminal absorbs the signal and keeps it from ringing, which is also known as overshot or resonance ; this is referred to as the maximum impedance. And if one cable is removed the bus...

...recognised courses on structured cabling systems which offer some hands-on experience, or you could take one of the many courses offered by the manufacturers of cabling components. Obviously the manufacturers try to sell their own products, but their courses are usually cheaper and they can still provide some of the basic cabling skills. | There are also lots of books on the subject of cabling and a selection of these can be found in the Network Cabling Help shop, my personal favourite is The Cabling Handbook 2nd Edition by John Vacca. It has over 1300 pages covering all aspects of network cabling and includes chapters on The Standards, Network Design, Wireless Communications, Fibre and Home Wiring. If you don't want to invest any money on training until you are seeing some financial results, then you can gain valuable experience by actually doing some work for an existing cabling company. Here are some basic questions you may be asking yourself if you have never installed a structured cabling system before. What are 'The standards' ? There are three main cabling standards: * EIA/TIA 568A - This is the American standard and was the first to be published (1991). * ISO/IEC 11801 - The International standard for structured cabling systems. * CENELEC EN 50173 - The European cabling standard. The reason for having a 'Standard' is to define a method of connecting all types of vendors voice and data equipment, over a cabling system that uses a common media,...

...Application (in terms of cabling infrastructure) – The technology that will take advantage of the cabling system. Applications include telephone systems (analog voice and digital voice), Ethernet, Token Ring, ATM, ISDN, and RS – 232. Unshielded Twisted Pair – A pair of copper wires twisted together with no electromagnetic shielding around them. Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out the electromagnetic interference that the transmission of electrical signal though the pairs generates. Shielded Twisted Pair – A type of twisted-pair cable in which the pairs are enclosed in an outer braided shield, although individual pairs may also be shielded. The pairs in STP cable have an individual shield, and the individual shielded cables are wrapped in an overall shield. The advantage of STP cable over UTP cable is that there is less attenuation at higher frequencies and is less susceptible to EMI. Fiber-Optic Cable – Fiber-optic cable uses a strand of glass or plastic to transmit data signals using light; the data is carries in light pulses. Unlike UTP/STP, the transmission techniques are not electrical in nature. Plastic-core is easier to install than traditional glass core, but plastic cannot carry data as far as glass. Dark Fiber – When telecommunication companies first run the fiber-optic cable, they don’t run the exact number of strands that they need. They install two to three...

Sonet Digital Hierarchy

...Digital Hierarchy Digital Transmission Hierarchies are made up of two main structures of digital networks. These two structures are known as Synchronous and Plesiochronous hierarchies. These relate to the transmission standards for all public telecommunication networks. Plesiochronous tasks the higher level multiplexers with "bit stuffing" techniques which inserts one or more bits of data into a single transmission unit to produce a signal to the receiver. (Rouse, 2014) Synchronous Hierarchy has all multiplexer units operating in accordance with common source clocks. (Rouse, 2014) SONET (Synchronous Optical Network) is Under the Synchronous model in the North American Hierarchy. SONET was developed in the 1980s and ,much like T(x), it was designed to carry large amounts of data over long distances and uses fiber optic cabling to transmit data on the network at very high speeds. SONET is based on the fundamental rate of 50.84 MBPS defined as Synchronous Transport Signal Level 1, or STS-1, which contrasts the International Synchronous Digital Hierarchy fundamental rate. The International Synchronous Digital Hierarchy has a fundamental rate of 155.520 MBPS, defined as STM-1 (Synchronous Transport Module Level 1). (Goleniewski, 2007) T(x) or T-Carrier, is the network standard in the North American region for Plesiochronous Digital Hierarchy (PDH) and uses a rate of 64Kbps per channel. T(x) was developed in 1957 by AT&T to support voice transmission pulse-code modulation to be...
