Different Types of Wireless Communication Technologies. Wireless Communication. 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., in a wireless communication technology network. At the end of the 1. Today, the term wireless refers to a variety of devices and technologies ranging from smart phones to laptops, tabs, computers, printers, Bluetooth, etc. Types of Wireless Communication Technologies. 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 are cordless telephones, mobiles, GPS units, Zig. Bee technology, wireless computer parts, and satellite television, etc. Types of Communication Technologies. Satellite. 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. Wireless Networking technologies connect multiple computers, systems and devices together without requiring wires or cables: a wireless local area network or WLAN comes under Wi- Fi. Wi. MAXThere are wireless broadband systems that offer fast Web surfing without being getting connected through cable or DSL (Example of wireless broadband is Wi. MAX). Although Wi. MAX can potentially deliver data rates of more than 3. 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 Wi. MAX widely varies with the distance from the transmitter. Wi. MAX is also one of the versions of 4. G wireless available in phones as Sprint’s 4. G technology. Wireless Networking. Wi- Fi. 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. Wi- Fi. Wireless Networking (Wi- Fi): Advantages. Ease of Integration and Convenience – The wireless nature of such networks allows users to access network resources from nearly any convenient location. Mobility – With the emergence of public wireless networks, users can access the internet even outside their normal working environment. Expandability – Wireless networks are capable of serving a suddenly- increased number of clients with the existing equipment. In a wired network, additional clients require additional wiring. Wireless Networking Wi. FIDisadvantages. Wireless LANs may not be desirable for a number of reasons. Radio Frequency transmission and wireless networking signals are subjected to a wide variety of interference including the complex propagation effects that are beyond the control of the network administrator. Security Problems – Wireless networks may choose to utilize some of the various encryption technologies. Range will be insufficient for a larger structure – and, in order to increase its range, repeaters or additional access points have to be purchased. The speed on most wireless networks will be slower than the slowest common wired networks. Installation of an infrastructure- based wireless network is a complex to set up. Bluetooth Technology. 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. 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. Bluetooth technology has many functions, and it is used most commonly in wireless communications’ market. Bluetooth Technology. Features. Bluetooth technology uses radio waves to communicate between devices. Most of these radio waves have a range of 1. According to the official Bluetooth website, Bluetooth uses a low- power signal with a maximum range of 5. The pairing process identifies and connects any two devices to each other. It also prevents interference from other non- paired Bluetooth devices in the area. It uses maximum power only when it is required, thus preserving battery life. Zig. Bee. Zig. Bee is a wireless communication standard designed to address the unique needs of low- power, low- cost wireless sensor, and control networks. Zig. Bee 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 data with a simple structure like the data from the sensors. Zigbee Technology. Features. Zig. Bee devices are designed for low- power consumption. Zig. Bee is used in Commercial Applications like sensing and monitoring applications. Zig. Bee uses very low power and extremely long device battery life. Zig. Bee gives flexibility to do more with the reliable wireless performance and battery operation. Types of Wireless Data Transmission. 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 Router. Wireless routers accepts an incoming Internet connection and sendsthe data as RF signals to other wireless devices that are near to the router. A network set up with a wireless router is called as a Wireless Local Area Network (WLAN). 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. Wireless Router. A wireless router is used in many houses to connect their computers to the Internet. Wireless Adapters. Wireless adapters are hardware devices that are installed inside computers which enables wireless connectivity. If a computer does not have a wireless adapter, it will not be able to connect to a router in order to access the Internet. Some computers have wireless adapters built directly into the motherboard, while it is also possible to install stand- alone wireless adapters to add wireless capability to a computer that doesn’t have a built- in facility. Wireless Repeater. 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. The strength of the signal can be increased by placing a repeater between the router and the computer connected to the router. Wireless Repeater. Microwave. Microwave is an effective 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 2. Earth. Stations on the ground send and receive data signals to and from the satellite with a frequency ranging from 1. GHz to 1. 4 GHz and with a transmission speed of 1 Mbps to 1. Mbps. Another method is a terrestrial method, in which two microwave 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. The frequency of data transmission for terrestrial systems is typically 4 GHz to 6 GHz or 2. GHz to 2. 3 GHz, and the speed is usually 1 megabit per second (Mbps) to 1. Mbps. Infrared (IR)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. The signal frequency to transmit in a point to point system is 1. GHz to 1,0. 00 terahertz (THz), and the speed ranges from 1. Kbps to 1. 6 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 1. GHz to 1,0. 00 THz with a limited speed of 1 Mbps. Infrared. Types of Wireless Devices.
