Electromagnetic waves are used for television broadcasts, cell phones, Bluetooth, radio, and every other form of wireless communication. Fiber optics cable is one of the costlier cables used in data communication which uses light to carry a data signal through the cable. Infrared light transmissions have existed for many years and their use having been limited to TV remote controls and wireless slide projector remote controls. Infrared. ... Infrared transmission. The communication via a WAN connection is maintained by providing a clock rate that is acceptable to both the sending and the receiving device. So networks are divided mainly of four types: PAN means a personal area network is the smallest network which is very personal to a user. Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications.Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy.. … Advantages of IrDA (Infrared) Following are the advantages of IrDA (Infrared): The devices are very cheap. Infrared propagation is line of sight. Here are some examples: Home-entertainment remote-control boxes. Infrared communication is among the simplest wireless communication methods, and it serves as a cost-effective way of transmitting a few bits of data wirelessly. A Personal Area Network (PAN) is a computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person. A LAN network can be client/server LAN or peer-to-peer LAN. However, a Wireless Persona… We can use different types of topologies through LAN, these are Star, Ring, Bus, Tree etc. Infrared Transmission : Infrared wave lies in between visible light spectrum and microwaves. In principle, upconversion nanoparticles (UCNPs) functionalized with a lysozyme‐binding aptamer were used to detect fingerprints through recognizing lysozyme in the fingerprint ridges. As a result, researches are being actively conducted to help each disabled person using information and communication technology. This network use in the personal space of a person that’s why this network name is a personal area network. PAN includes mobile devices, tablet, and laptop. Infrared has long been used in night vision equipment and TV remote control. Infrared spectrum is categorized into three regions based on its wavelength i.e. It is used for the network that covers large distance such as cover states of a country. TSOP sensor is used in our daily use TV, VCD, music system’s remote control. Active-infrared night vision: the camera illuminates the scene at infrared wavelengths invisible to the human eye. The infrared light is used for many years for the communication directly between nearby devices to each other, such as remote control and your television, for example. Communication medium used by WAN are PSTN or Satellite links. It is more secure compare to RF technologies. Using Ethernet cables, data transfer speed can reach up to 10 Mbps and by using FDDI or Gigabit Ethernet, data transfer speed can reach up to 1 Gbps. so let’s discuss. An infrared (IR) sensor is an electronic device that radiates or locates infrared radiation to sense some part of its surroundings. IR sensors mostly used in radiation thermometer, gas analyzers, industrial applications, IR imaging devices, tracking, and human body detection, communication and health hazards. IR light is very similar to visible light, except that it has a slightly longer wavelength. Wide Area Network (WAN) It is also called WAN. WAN A Wide Area Network (WAN) is used to connect LANs and other types of network together, so that users and computers in one location can communicate with users and computers in other locations. Security: Infrared communication has high directionality and can identify the source as different sources emit radiation of different frequencies and thus the risk of information being diffused is eliminated. WAN’s are used to connect local area networks (LAN’s) together, so that users and computers in one location can communicate with users and computers in other locations. TSOP is sensitive to a specific frequency so its range is better contrast with ordinary photo diode. Wireless LANs have several disadvantages. A photo diode is connected in reverse biased condition through a potential divider of a 10k variable resistance and 1k in series to the base of the transistor. Communications using Infrared – Infrared data transmission is used for short range communications, for example between computer peripherals to transfer files, remote controls.
