The term wireless refers to the communication or transmission of information over a distance without requiring wires, cables or any other electrical conductors.

Wireless communication is one of the important mediums of transmission of data or information to other devices. The Communication is set and the information is transmitted through the air, without requiring any cables, by using electromagnetic waves like radio frequencies, infrared, satellite, etc.

At the end of the 19th century, the first wireless communication systems were introduced and the technology has significantly been developed over the wimas and subsequent years. Today, the term wireless refers to a variety of devices and technologies ranging from smart phones to laptops, tabs, computers, printers, Bluetooth, etc. In recent days, the wireless communication technology has become an integral part of several types of communication devices as it allows users to communicate even from remote areas.

The devices used for wireless communication filetupe cordless telephones, mobiles, GPS units, ZigBee technology, wireless computer parts, and satellite television, etc. Satellite communication is one of the wireless technologies, which is widely spread all over the world allowing users to stay connected virtually anywhere on the Earth.

The Satellites used in this mode of communication, communicate directly with the orbiting satellites via radio signals.

Portable satellite phones and modems have more powerful broadcasting abilities than the cellular devices as they have high range, apart from being more expensive in terms of cost, than their counterparts. For example, for outfitting a ship through satellite communication, a traditional communication system is linked to a single satellite, which allows multiple users to share the same broadcast equipment.

Wireless Networking technologies connect multiple computers, systems and devices together without requiring wires or cables: Although WiMAX can potentially deliver data rates of more than 30 Megabits per second, yet the providers offer average 0 data rates of 6 Mbps and often deliver less, making the service significantly slower than the hard-wired broadband.

The actual cost of the data available using WiMAX widely varies with the distance from the transmitter. Wi-Fi is a form of low-power wireless communication used by many electronic devices such as laptops, systems, smart phones, etc. In a Wi-Fi setup, a wireless router serves as the communication hub.

These networks are extremely limited in range due to low power of transmissions allowing users to connect only within close proximity to a router or signal repeater.

Wi-Fi is common in home networking applications which provides portability without any need of cables. Wi-Fi networks need to be secured with passwords for security purposes in order not to be accessed by others. Bluetooth technology allows you to connect a variety of different electronic devices wirelessly to a system for the transfer and sharing of data and this is the main function of Bluetooth.

WiMAX Introduction |

Cell phones are connected to hands-free earpieces, wireless keyboard, mouse and mike to laptops with the help of Bluetooth as it transmits information from one device to other device.

ZigBee is a wireless communication standard filetypw to address the unique needs of low-power, low-cost wireless sensor, and control networks. ZigBee can be used almost anywhere, as it is easy to implement and requires little power to operate.

Zigbee has been developed looking into the needs of the communication of fuletype with a simple structure like the data from the sensors. Wireless technology defines the electronic devices that communicate in air without cables using radio frequency signals. Wireless technology is used in a variety of modern device and provides greater mobility. Wireless devices play an important role in voice and Internet communications.

Wireless routers accepts an incoming Internet connection and sendsthe data as RF signals to other wireless devices that are near to the router. Many routers have built-in security features such as firewalls that help protect devices connected to the router against malicious data such as computer viruses. A wireless router is used in many houses to connect their computers to the Internet. Wireless adapters are hardware devices that are installed inside computers which enables wireless connectivity.

If a computer does wjmax have a wireless adapter, it will not be able to connect to a router in order to access the Internet. A wireless repeater is a wireless networking device that is used to extend the range of a wireless router. A repeater receives wireless signals and amplifies the strength of the signals, and then re-emits them.

Wireless Communication Technologies Types and Advantages

The strength of the signal can be increased by placing a repeater between the router and the computer connected to the router. Microwave is an flietype type of wireless data transmission that transfers information using two separate methods.

One method which is used to transmit data through the wireless media of a microwave is the satellite method that transmits information via a satellite that orbits 22, miles above the Earth. Stations inyroduction the ground send and receive data signals to and from the satellite with a frequency ranging from 11 GHz to 14 GHz and with a transmission speed of 1 Mbps to 10 Mbps. Another method is a terrestrial method, in which two wmiax towers with a clear line of sight between them are used ensuring no obstacles to disrupt that line of sight.

For the purpose of privacy, it is used often. Infrared is a media transmission system that transmits data signals through light emitting diodes LEDs or Lasers. Infrared is an electromagnetic energy at a wavelength which is longer than that of the red light. The information cannot be travelled through obstacles in an infrared system, but can be inhibited by light.

One type of infrared is the point to point system in which transmission is possible between two points limited to a range and line of sight.

Different Types of Wireless Communication Technologies

The signal frequency to transmit in a point to point system is GHz to 1, terahertz THzand the speed ranges from Kbps to 16 Mbps. Another method of transmission of infrared includes the broadcast system — and, in this method, a reflective material or a transmission unit amplifies and retransmits a data signal to several other units.

The normal frequency of an infrared broadcast system is GHz to 1, THz with a limited speed of 1 Mbps.

The radio system is one type of wireless data transmission, and it is a wireless media that transfers data by carrying electromagnetic waves with low frequencies to distant locations through an electrical conductor and an antenna.

Ham radio enthusiasts share information filletype serve as emergency communication aids during disasters with their powerful amateur broadcasting equipment and can even communicate digital data over the radio spectrum. The transmission frequency for information transmitted introdjction a radio system ranges from filwtype kilohertz kHz to 1 gigahertz GHzand the frequencies are regulated by the Federal Communications Commission FCC.

The evolution of cellular networks is enumerated by generations. Many different users communicate across a single frequency band through Filletype and cordless phones.

Cellular and cordless phones are two more examples of devices that make use of wireless signals. Cordless phones have a limited range but cell phones typically have a much larger range than the local wireless networks since cell phone use large telecommunication towers to provide cell phone coverage.

Anything that uses radio signals to communicate can be considered as a wireless device. Common devices such as garage door openers, baby monitors, certain video game consoles and walkie-talkies make use of wireless technology. Thus, Wireless networks are one of the fastest growing technologies in telecommunications market. Radio, Mobiles, Internet, etc. The information provided in this article will be helpful to the viewers.
