It is used to transmit infrared signals or modulated visible signals through the environment to attain optical communications similar to fiber. In FSO communication, lasers are used for transmitting the data, but in place of enclosing the data flow within a glass fiber, the data can be transmitted throughout the air.

The working principle of FSO is the same as to IR TV remote or wireless keyboard. Free Space Optics (FSO) transmits invisible, light beams through low power IR lasers in the frequency of the TeraHertz spectrum. In the FSO, the light beams are sent through a laser light that is focused on very responsive photon detector receivers.

These are telescopic lenses capable of collecting the photon stream & transmit digital data includes a mix of video images, Internet messages, radio signals otherwise computer files. FSO systems operate over several kilometers of distance if there is a clear line of view between the source & the destination with sufficient transmitter power.

Silent Sound Technology

Whenever we are traveling on the bus or train, speaking on the phone is somewhat difficult due to the disturbances. So we speak very loudly to receive our voice to another person on the phone. For this, Silent sound technology is implemented to speak on the phone while traveling.

The main function of this technology is to notice each lip movement & converts the electrical pulses internally into sound signals. These signals can be transmitted by removing the noise in the surroundings. This technology is very helpful for the people who cannot speak clearly due to noise & allows them to make noiseless calls without troubling others.

Instead of making any noises, your earpiece will decode the mouth movements which makes by determining muscle action, after that converts this into speech listen to the other side of the person on the phone. This translation supports different languages such as English, German & French. However, for the Chinese languages, different tones have different meanings

Bionic Eyes

The bionic eye is an artificial eye and the main function of this eye is to provoke visual vibrations within the human brain by motivating different elements of the optic nerve directly. Other investigational places can excite the ganglia cells over the retina. So, there is more attention is given to the artificial retinas for making. There are different kinds of artificial eyes are designed but there is no typical model. So scientists are working on different kinds of ideas.

The prototype of this eye is 2 millimeters across & includes 3,500 micro photodiodes that are arranged at the back of the retina. This mini solar cell collection can be designed to change the normal beam to electrical signals. These signals are sent to the human brain through the residual well parts of the eye retina.


An electromagnetic bomb (E bomb) is one kind of weapon.

Communication through Visible Light

VLC systems (Visible Light Communication) use visible light for communication to occupy the range from 380 nm – 750 nm that is equivalent to 430 THz – 790 THz of a frequency spectrum.
The low BW issue within RF communication can be determined in Visible Light Communication due to the accessibility of the huge bandwidth. The receiver of the VLC simply gets the signals if they exist in a similar room to the transmitter.

Thus, the receivers outside of the VLC source room are not capable of receiving the signals. So, it has the resistance to safety problems that happen within the RF communication systems. Whenever the source of visible light is used for both illumination as well as communication, so, it conserves an additional power that is necessary for RF communication. VLC provides several advantages like high bandwidth, non-licensed channels & low power usage.

This kind of communication is used in Li-Fi, robots within hospitals, communication from vehicle to vehicle; communication underwater, signboards for displaying information. VLC is used within vehicular communication intended for warning of the lane change, sensing of pre-crash & violation warning of the traffic signal for avoiding accidents.

For these applications, low latency communication is required that is provided through VLC due to its higher BW & simple installation due to the existence of vehicle lights & traffic signals.

OFDM Implementation through VLSI

A multi-carrier system like OFDM is used to encode the data bits for numerous sub-carriers and sends simultaneously in time and it uses optimum bandwidth. An OFDM symbol can be formed by a set of orthogonal sub-carriers. To avoid inter-symbol interference (ISI) because of multi-path; the symbols of successive OFDM are divided using a guard band. So this band will make the system of OFDM resistant to the effects of multi-path.

Even though this system within the theory has been in existence for a lengthy time, current developments within the technologies like VLSI & DSP have made it a possible option. This project implements an OFDM using VLSI for especially the 802.11a based OFDM system. But, the same reflections would be useful in executing any OFDM system within VLSI.

In this multi-carrier system, data bits can be encoded to several subcarriers, not like single carrier systems. All the frequencies are sent simultaneously in time and this system provides numerous benefits over an only carrier system such as equalization of the simpler channel, relaxed timing gaining constraints & better multi-path affect immunity. However, it is more vulnerable to local frequency offset & non-linearities of radio front-end.

Transmission of Microwave Power

An SPS or solar power satellite is one kind of renewable energy system. This satellite is used to change the energy of solar into microwaves. These microwaves are transmitted to a beam and receive antenna on the globe so that it converts into normal Electricity.

The first concept of SPS was proposed in the USA, in 1968. At present, this concept was attracted by the people to enhance public attention because a promising energy system is used to determine the problems of energy & the global environment. This solar power satellite is a dirt-free, secure & large-scale electric power source.

FBG – Fiber Bragg Gratings

Fiber-optic communication (FOC) is one kind of technique for transmitting data from one area to another through transmitting light pulses using an optical fiber. The electromagnetic carrier signal can be formed by light that is adjusted to hold the data. The main advantage of this fiber optic communication is to provide a very low loss, allows long communication between repeaters otherwise amplifiers.

It has high data carrying capability inherently so that number of electrical links would be necessary to change a single high BW fiber optic cable. Another benefit of fibers is that it can transmit the data for long distances. These cables experience efficiently no crosstalk, on the contrary to some kinds of electrical transmission lines.

A VANET is a type of ad hoc network for mobile users to provide communications between near vehicles, in between two vehicles & close to the fixed device on the roadside. These networks are also called VANETs which are believed like one of the ad-hoc n/w real-life application that allows communications between close-by vehicles.

Mobile Train Radio Communication

A separate and temporary radio channel is used in each mobile to speak with the cell site. At a time, this cell site speaks with several mobiles through a single channel for each mobile. These radio channels use a set of frequencies for communication purposes. One frequency is used for transmitting. One for transmitting the data from the site of cell & remaining one is to get the calls from the operators. The communication used between mobile units is half-duplex otherwise full-duplex.

In a half-duplex case, the communications among the mobile units are not all at once, so listening and talking cannot be done at a time, whereas in full-duplex, the communication can be done at a time. Once communications among mobile units are in a cell & if the same is in half-duplex, after that it uses simply one set of frequency. If the same is full-duplex, then a requirement of frequency pair shall be two.

Whenever a mobile unit is interacting through a mobile unit at the exterior of the cell, after that the necessity of a set of frequency shall be single for each cell for both the communication. Therefore, the resources of the system are used more if the mobile units converse with each other within the full-duplex form.

HART Communication

The full form of HART protocol is “Highway Addressable Remote Transducer”. This protocol uses FSK (Frequency Shift Keying) to place over digital communication signals. This allows field communication is two-way. This protocol converses at 1200 bps without interrupting 4 to 20mA signal. This signal permits a host application to obtain two otherwise more digital updates for each second using a smart field machine.

This protocol gives two instantaneous communication channels like the 4mA to 20mA based analog & a digital signal. This signal converses the primary measured value through the 4mA to 20mA current loop. Extra device data can converse through a digital signal.

HART Communication mainly occurs among two devices which are enabled through HART. The communication mainly occurs through typical instrumentation wire, standard wiring & termination practices.

Telecommunication Networks

The telecommunication network is one kind of transmission system that allows the data to be sent in the form of analog otherwise digital in between several different sites through optical or electromagnetic signals. This data includes audio, video data otherwise some other kind of data. These networks are based on wired otherwise wireless communications. The best examples of these networks are the mobile n/w, telephone landline n/w, and internet & cable TV networks. In two-way speech transmission, different kinds of phone networks are used.

Previously, data transmission can be done based on the wire. The speech signals can be transmitted through analog, electromagnetic signals. At present, the phone networks are digital and the network can be landline or mobile.

High Altitude Platforms for Wireless Communication

At present, most of the communication can be done wirelessly at a quick speed. Most people use wireless communication with high speed to transmit the data so that they do not irritate by using wires. The communication with HAP (High Altitude Platforms) allows rural areas & remote villages to allow communication with high speed.

HAAPS – High Altitude Aeronautical Platforms

The HAAPS (High Altitude Aeronautical Platform Stations) is one kind of technology used to provide services like wireless narrowband, broadband telecommunication & broadcasting services using aircraft or airships. The high-altitude aeronautical platforms work at altitudes among 3km to 22 km.

This covers a service region up to 1000 km width based on the smallest elevation angle that is allowed from the location of the user. These platforms may be airships or airplanes & manned otherwise un-manned through autonomous processes coupled through remote control from the earth. HAAPS is a solar-powered as well as unmanned airship otherwise airplane that is capable for long fortitude on-station probably several years.

Blue Eyes Technology

Blue Eyes technology is used to monitor as well as record the basic physiological factor of the operator. And, saccadic activity1 is the most significant parameter that allows the system to check the position of the visual attention of the operator through head acceleration that comes with a huge displacement of the visual axis.

The difficult situation in the industry can make a risk of exposing the worker to poisonous materials, which can influence his circulatory, cardiac & pulmonary systems. Therefore, on the basis of the plethysmographic signal received from the surface forehead skin, the system calculates blood oxygenation & heartbeat rate.

Optical Mouse

An advanced computer pointing device like an optical mouse can be built with an optical sensor, LED & DSP (digital signal processing) instead of the fixed mouse ball as well as the electromechanical transducer.

The movement of the mouse can be detected through changes within reflected light instead of interpreting the movement of an undulating sphere. This mouse takes the snapshots of the microscopic of the functioning surface at a rate of above 1,000 images for each second.

If this mouse is moved, then the image will change. The smallest abnormalities within the exterior can generate images sufficient for the DSP & sensor to produce functional movement data. Some surfaces don’t permit the DSP & sensor to work correctly as the abnormalities are too tiny to be noticed. An unfrosted glass is the best example of a surface of poor optical-mousing.

Actually, an optical mouse does not require cleaning, as it doesn’t include moving parts. This feature also removes mechanical exhaustion. If the mouse device is used with a suitable surface, then noticing is more exact as compared through any pointing device with the older electromechanical design. This is a benefit in the applications of graphics & it makes the operation of computers easier.
