A mobile phone (also called mobile cellular network, cell phone or hand phone) is an example of mobile communication (wireless communication). These have the relatively low bandwidth for data transmission. There are different types of wireless communication which include satellite communication, microwave line of sight communication, cellular communication (GSM, CDMA, LTE etc. ZigBee gives flexibility to do more with the reliable wireless performance and battery operation. … The range of a WLAN can be anywhere from a single room to an entire campus. 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 time variation of received signal power due to changes in transmission medium or paths is known as fading.Fading depends on various factors as mentioned above.In fixed scenario, fading depends on atmospheric conditions such as rainfall, lightening etc.In mobile scenario, fading depends on obstacles over the path which are varying with respect to time.These obstacles create com… Satellite Communication Course . The laser beam gets easily diverted by air. For wireless LANs, a key component is the wireless hub, or access point, used for signal distribution (see Figure 8-8).. Since there are many wireless communication protocol available to use for your product, it becomes difficult for the product designers to choose the correct one but once the scope of IoT application is decided it would … WiFi, WiMax, Bluetooth, Femtocell, 3G and 4G are some of the most important standards of Wireless technology. Wireless Communication . Transmission of music, news, road conditions, weather reports, and other broadcast information are received via digital audio broadcasting (DAB) with 1.5Mbit/s. Since then, the wireless technologies that make “on-the-move” communication possible for us have evolved remarkably. The most common wireless technologies use radio. ZigBee devices are designed for low-power consumption. Radio Frequency Seawater- Pipeline Inspection Guage/Submarine Communication Seawater –Submarine Communication Earth- Communication in Mines / 40m in Saltwater –Wireless Telegraph Kilometer wave - Long Distance Communication Hectometer wave - AM … Optical Fiber Comm. 3. 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. 02 - Types of Wireless Communication ; In 1897 Gugliemo Marconi was the first to demonstrate that it was possible to establish a continuous communication stream with the ships that were sailing in the English Channel, by means of radio waves. Wireless communication is influenced by physical constructions, climatic conditions and interference from other wireless devices. Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors. This is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices. The internet can be accessed from anywhere, at any time without any cables or wires. ZigBee uses very low power and extremely long device battery life. Wireless communication technologies are everywhere. Security Problems – Wireless networks may choose to utilize some of the various encryption technologies. Otherwise known as free-space optics, these technologies are direct alternatives to wired optical communication systems such as optical fiber cablesystems and radio-based wireless communication. Wireless communication uses radio frequencies (RF) or infrared (IR) waves to transmit data between devices on a LAN. Frequency, Range and type of Wireless Communication Zyyad Ali Shah Syed NSA, UiO, Autum 2016. We can use different types of topologies through LAN, these are Star, Ring, Bus, Tree etc. – With the emergence of public wireless networks, users can access the internet even outside their normal working environment. From this beginning, wireless … ), short range wireless communication (WLAN, Bluetooth, Zigbee, Zwave, LoRaWAN etc.). The microwave does not pass through buildings. Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
