Therefore, this is all about Types of wireless communication and applications, these networks are one of the important technologies in the telecommunications market. The variations can be roughly divided into two types (Figure 2.1): • Large-scale fading, due to path loss of signal as a function of distance and shadowing by large objects such as buildings and hills. They allow devices to be connected to the network while roaming around within the network coverage. Types Of Wireless Networks. Modes of Wireless Communication. Communication is a very basic and fundamental process for human beings. Optical wireless communications (OWC) is a form of optical communication in which unguided visible, infrared (IR), or ultraviolet (UV) light is used to carry a signal.. OWC systems operating in the visible band (390–750 nm) are commonly referred to as visible light communication (VLC). 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. View satellite.ppt from CS 490 at SIMAD University - Mogadishu. Today, facilitated by RF circuit fabrication and digital It enables a user to move within a wide coverage area but still connected to the network. Many wireless communication systems and mobility aware applications are used for following purpose: Transmission of music, news, road conditions, weather reports, and other broadcast information are received via digital audio broadcasting (DAB) with 1.5Mbit/s. Wireless devices send their signal to the AP, which relays the signal to the destination wireless station or the wired network. WiFi, WiMax, Bluetooth, Femtocell, 3G and 4G are some of the most important standards of Wireless technology. Amplitude Modulation (AM), used for AM radio, uses a high speed carrier frequency and imposes the signal onto the carrier by adjusting the carrier's amplitude. These devices include personal digital assistants (PDAs), laptops, personal computers (PCs), servers, and printers. Wireless Communication Seminar ppt and pdf Report. Mobile wireless communication system has gone through several evolution stages in the past few decades after the introduction of the first generation mobile network in early 1980s.
