Infrared Transmission Media - Essay Assignment 2
Purpose of the Infrared Transmission Media To start off, let us establish what infrared transmission is in the context of networking. Infrared transmission is merely an alternative means of wireless communication of electronic devices. The most common method of wireless transmission is radio waves, which is what your wireless router operates on. Infrared transmission is the same concept as your radio wave transmission but operates much differently. We use infrared transmission media every day of our lives without considering the fact that we are. This is because infrared technology is very commonly used in remote controls for garage doors and televisions due to its low cost and lack of licensing …show more content…

Reasoning as to why infrared light is used as opposed to visible light is derived from the fact that visible light is much more susceptible to interference. Thus, we end up with the infrared light spectrum, which is the most reliable spectrum of light that can be used for unguided network communication. When multiple devices are setup to use a direct infrared connection, they communicate via their infrared devices emitting pulses of light towards each other. Most every day devices which rely on infrared transmission such as garage door openers and television remotes use these pulses or flashes in specific combinations to signify different commands. Computers, though, cannot use this method under normal circumstances due to the way binary code operates. This is due to the fact that if each pulse is a 1 then the absence of a pulse would be a 0, thus one can see where many problems can arise. To solve this, there is a protocol which infrared transmission operates known as IrDA (Infrared Data Association) which regulates how infrared devices communicate. The methods of connection which were just spoken of are referred to as direct connections, there is another way to connect infrared devices though. This alternative is known as diffuse technology where a special access point diffuses infrared light in such a way as to …show more content…

Not to get too technical, but the first advantage that infrared technology has over its competitors is that the infrared light spectrum has one of the widest bandwidths. This means that it can theoretically be extremely fast with very large amounts of data if set up correctly. That proper setup being either in short distances outside at night or for a LAN network within a number of adjacent rooms. If setup properly, an infrared connection can be extremely reliable if nothing passes through its transmission path. If the area you wish to construct a network in fits within the guidelines, then a extremely poignant advantage is the low cost associated with infrared

    Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.

  • The Use of Light as a Communication Media: China Great Wall

    The use of light as a communication media used in China Great Wall distance more than 7300 km with in 1 hour to sent signal from one tower to another. In the late 20th century optical communication took back in to the seat for its advantages over coaxial transport and other electrical communication system. In 1966, Kaw and Hockman proposed the idea of using optical fiber light wave communication and their prediction was data loss 20dB/km [12]. In late 1980s to 1990s, coherent detection communication systems were introduced to enhance the transmission system. However, optical system needs still regeneration over long distance. By early 1990s, the system channel capacity boosted and reached to 10Gb/s but in 2003 it reached up to 40Gb/s via support WDM system. Recently, some experiments have done to transmit data 21.7 Tb/s though crossing the 10Tb/s per fiber barrier and it is new challenges for optical communication to innovate novel schemes of optical amplification, modulation technique or Fiber channel design.

    Infrared Data Association (IrDA) founded on 1993. IrDA is utilized for high speed short range, line of sight, point-to-point cordless data transfer via infrared light waves. IrDA is the radio transmission of light ray infrared measured in Terahertz or Trillions of Hertz (cycles per seconds) is modulated with information send from transmitter to receiver in short distance. Does not specify any security measures. Infrared radiation(IR) is used to control a TV set with a remote control. Infrared data communication is most use in wireless data communication due to popularity of laptop computers, personal digital assistant(PDA), digital cameras, mobile telephone, pagers and other devices. IrDA specifications include IrPHY, IrLAP, IrLMP, IrCOMM, Tiny TP, IrOBEX, IrLAN, and IrSimple.

    LANs systems can be defined and connected in many different ways. This is the reason for the standardization for every one can have a common ground to start from. “The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to Wide Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a public utility. These LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.”(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technical words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information across global areas.

Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly.
