Telecommunication

Telecom is the transmission of signals over long distances. It began with the invention of the telegraph in 1837, followed by the telephone in 1876. Radio broadcasts began in late 1800s and the first television broadcasts started in the early 1900s. Today, popular forms of telecommunications include the Internet and cellular phone networks.

Early telecommunications transmissions used analogue signals, which were transferred over copper wires. Today, telephone and cable companies still use these same lines, though most transmissions are now digital. For this reason, most new telecommunications wiring is done with cables that are optimized for digital communication, such as fiber optic cables and digital phone lines. Since both analogue and digital communications are based on electrical signals, transmitted data is received almost instantaneously, regardless of the distance. This allows people to quickly communicate with others across the street or across the globe. So whether you're watching TV, sending an email to a co-worker, or talking on the phone with a friend, you can thank telecommunications for making it possible.

Spectrum Designing

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.

The electromagnetic spectrum extends from below the low frequencies used for modern radio communication to gamma radiation at the short-wavelength (high-frequency) end, thereby covering wavelengths from thousands of kilometres down to a fraction of the size of an atom. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length. Until the middle of last century it was believed by most physicists that this spectrum was infinite and continuous.

Most parts of the electromagnetic spectrum are used in science for spectroscopic and other probing interactions, as ways to study and characterize matter.In addition, radiation from various parts of the spectrum has found many other uses for communications and manufacturing (see electromagnetic radiation for more applications).

The electromagnetic spectrum



A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths

Boundaries
A discussion of the regions (or bands or types) of the electromagnetic spectrum is given below. Note that there are no precisely defined boundaries between the bands of the electromagnetic spectrum; rather they fade into each other like the bands in a rainbow (which is the sub-spectrum of visible light). Radiation of each frequency and wavelength (or in each band) will have a mixture of properties of two regions of the spectrum that bound it. For example, red light resembles infrared radiation in that it can excite and add energy to some chemicalbonds and indeed must do so to power the chemical mechanisms responsible for photosynthesis and the working of the visualsystem.

Regions of the spectrum

The types of electromagnetic radiation are broadly classified into the following classes:

  • Gamma radiation
  • X-ray radiation
  • Ultraviolet radiation
  • Visible radiation
  • Infrared radiation
  • Terahertz radiation
  • Microwave radiation
  • Radio waves

This classification goes in the increasing order of wavelength, which is characteristic of the type of radiation. While, in general, the classification scheme is accurate, in reality there is often some overlap between neighbouring types of electromagnetic energy. For example, SLF radio waves at 60 Hz may be received and studied by astronomers, or may be ducted along wires as electric power, although the latter is, in the strict sense, not electromagnetic radiation at all.

The distinction between X-rays and gamma rays is partly based on sources: the photons generated from nuclear decay or other nuclear and sub nuclear/particle process, are always termed gamma rays, whereas X-rays are generated by electronic transitions involving highly energetic inner atomic electrons. In general, nuclear transitions are much more energetic than electronic transitions, so gamma-rays are more energetic than X-rays, but exceptions exist. By analogy to electronic transitions, muonic atom transitions are also said to produce X-rays, even though their energy may exceed 6 megaelectronvolts (0.96 pJ), whereas there are many (77 known to be less than 10 keV (1.6 fJ)) low-energy nuclear transitions (e.g., the 7.6 eV (1.22 aJ) nuclear transition of thorium-229), and, despite being one million-fold less energetic than some muonic X-rays, the emitted photons are still called gamma rays due to their nuclear origin.

The convention that EM radiation that is known to come from the nucleus, is always called "gamma ray" radiation is the only convention that is universally respected, however. Many astronomical gamma ray sources (such as gamma ray bursts) are known to be too energetic (in both intensity and wavelength) to be of nuclear origin. Quite often, in high energy physics and in medical radiotherapy, very high energy EMR (in the >10 MeV region) which is of higher energy than any nuclear gamma ray, is not referred to as either X-ray or gamma-ray, but instead by the generic term of "high energy photons."

The region of the spectrum in which a particular observed electromagnetic radiation falls, is reference frame-dependent (due to the Doppler shift for light), so EM radiation that one observer would say is in one region of the spectrum could appear to an observer moving at a substantial fraction of the speed of light with respect to the first to be in another part of the spectrum. For example, consider the cosmic microwave background. It was produced, when matter and radiation decoupled, by the de-excitation of hydrogen atoms to the ground state. These photons were from Lyman series transitions, putting them in the ultraviolet (UV) part of the electromagnetic spectrum. Now this radiation has undergone enough cosmological red shift to put it into the microwave region of the spectrum for observers moving slowly (compared to the speed of light) with respect to the cosmos.

Spectrum management is the process of regulating the use of radio frequencies to promote efficient use and gain a net social benefit. The term radio spectrum typically refers to the full frequency range from 3 kHz to 300 GHz that may be used for wireless communication. Increasing demand for services such as mobile telephones and many others has required changes in the philosophy of spectrum management. Demand for wireless broadband has soared due to technological innovation, such as 3G and 4G mobile services, and the rapid expansion of wireless internet services. Since the 1930s, spectrum was assigned through administrative licensing. Limited by technology, signal interference was once considered as a major problem of spectrum use. Therefore, exclusive licensing was established to protect licensees' signals. This former practice of discrete bands licensed to groups of similar services is giving way, in many countries, to a "spectrum auction" model that is intended to speed technological innovation and improve the efficiency of spectrum use. During the experimental process of spectrum assignment, other approaches have also been carried out, namely, lotteries, unlicensed access and privatization of spectrum. Most recently, the President's Council of Advisors for Science and Technology (PCAST) advocated the sharing of (unclear) federal radio spectrum when unused at a place and time provided it does not pose undue risks. Following PCAST's recommendations, President Obama made shared spectrum the policy of the United States on 14 June 2013 Shared Spectrum. As of Dec 2014 the FCC was extending the limited success of television band spectrum sharing (TV white space) into other bands, significantly into the 3550-3700 MHz US Navy radar band via a three tier licensing model (incumbent, priority, and general access) while Europe has been pursuing an authorized shared access (ASA) licensing.

Trenchless Technology (Directional Drilling)



The Trenchless Technology–( A Small Introduction)

The tools and techniques used in the horizontal directional drilling (HDD) process are an Outgrowth of the oil well drilling industry. The components of a horizontal drilling rig used for Pipeline constructions are similar to those of an oil well drilling rig with the major exception being That a horizontal drilling rig is equipped with an inclined ramp as opposed to a vertical mast. HDD Pilot hole operations are not unlike those involved in drilling a directional oil well. Drill pipe and Down hole tools are generally interchangeable and drilling fluid is used throughout the operation to Transport drilled spoil, reduce friction, stabilize the hole, etc.


Pilot Hole Directional Drilling



Pilot hole directional control is achieved by using a nonrotating drill string with an asymmetrical leading edge. The asymmetry of the leading edge creates a steering bias while the nonrotating aspect of the drill string allows the steering bias to be held in a specific position while drilling. If a change in direction is required, the drill string is rolled so that the direction of bias is the same as the desired change in direction. The direction of bias is referred to as the tool face. Straight progress may be achieved by drilling with a series of offsetting tool face positions. The drill string may also be continually rotated where directional control is not required. Leading edge asymmetry can be accomplished by several methods.


Bottom Hole Assemble down hole Motors

Downhole mechanical cutting action required for harder soils is provided by down hole hydraulic motors. Downhole hydraulic motors, commonly referred to as mud motors, convert hydraulic energy from drilling mud pumped from the surface to mechanical energy at the bit. This allows for bit rotation without drill string rotation. There are two basic types of mud motors; positive displacement and turbine. Positive displacement motors are typically used in HDD applications. Basically, a positive displacement mud motor consists of a spiral-shaped stator containing a sinusoidal shaped rotor. Mud flow through the stator imparts rotation to the rotor which is in turn connected through a linkage to the bit.

In some cases, a larger diameter wash pipe may be rotated concentrically over the non-rotating steerable drill string. This serves to prevent sticking of the steerable string and allows its tool face


Down Hole Surveying



The actual path of the pilot hole Down hole Surveying – is monitored during drilling by taking periodic readings of the inclination and azimuth of the leading edge. Readings are taken with an instrument, commonly referred to as a probe, inserted in a drill collar as close as possible to the drill bit. Transmission of down hole probe survey readings to the surface is generally accomplished through a wire running inside the drill string. These readings, in conjunction with measurements of the distance drilled since the last survey, are used to calculate the horizontal and vertical coordinates along the pilot hole relative to the initial entry point on the surface Azimuth readings are taken from the earth's magnetic field and are subject to interference from down hole tools, drill pipe, and magnetic fields created by adjacent structures.

Therefore, the probe must be inserted in a non magnetic collar and positioned in the string so that it is Adequately isolated from downhole tools and drill pipe. The combination of bit, mud motor (if used), subs, survey probe, and non magnetic collars is referred to as the Bottom Hole Assembly or BHA.


Surface Monitoring



The pilot hole path may also be tracked using a surface monitoring system. Surface monitoring systems determine the location of the probe down hole by taking measurements from a grid or point on the surface. An example of this is the TruTracker System. This system uses a surface coil of known location to induce a magnetic field. The probe senses its location relative to this induced magnetic field and communicates this information to the surface.


Tru-Truker Surface Monitoring System



Reaming & Pullback

Enlarging the pilot hole is accomplished using either pre-reaming passes prior to pipe installation or simultaneously during pipe installation. Reaming tools typically consist of a circular array of cutters and drilling fluid jets and are often custom made by contractors for a particular hole size or type of soil.

Pre-Reaming



Most contractors will opt to pre-ream a pilot hole before attempting to install pipe. For a Pre-reaming pass, reamers attached to the drill string at the exit point are rotated and drawn to the drilling rig thus enlarging the pilot hole. Drill pipe is added behind the reamers as they progress toward the drill rig. This insures that a string of pipe is always maintained in the drilled hole. It is also possible to ream away from the drill rig. In this case, reamers fitted into the drill string at the rig are rotated and thrust away from it


Pullback


Pipe installation is accomplished by attaching the prefabricated pipeline pull section behind a reaming assembly at the exit point and pulling the reaming assembly and pull section back to the drilling rig. This is undertaken after completion of pre-reaming or, for smaller diameter lines in soft soils, directly after completion of the pilot hole. A swivel is utilized to connect the pull section to the leading reaming assembly to minimize torsion transmitted to the pipe. The pull section is supported using some combination of roller stands, pipe handling equipment, or a flotation ditch to minimize tension and prevent damage to the pipe.

Trenching

Excavation of Trenches Standard depth of trench will be as per specifications Outside the city limits trench will normally follow boundary of roadside land.

However, where road side land is full of borrow pits or forestation, or when cable is to be laid along Culverts/bridges or cross-streams, trench may be made closer to road edge or in some cases, over embankment or shoulder of the road.

Line up of trench would be such that HDPE duct(s) will be laid in straight line, both laterally as well as vertically except at locations where it has to necessarily take a bend because of change in alignment or gradient of trench. Minimum radius of two meters will be maintained, where bends are necessitated
