Different wireless technologies pdf

While in the modern use, in early 20s, the term "wireless" started to be used to define the technology that doesn't requires cables. During that time period until now, many people use "wireless" term to refer technology such as Bluetooth, WLAN, NFC, RFID, Zigbee and LTE and many more the types of wireless technology. Chapter 7: Telecommunications, the Internet, and Wireless Technology Illustrated here is a very simple computer network, consisting of computers, a network operating system residing on a dedicated server computer, cabling (wiring) connecting the devices, network interface cards (NIC), switches, and a router. Figure 7-1 ZigBee technology is a wireless sensor network system that ensures remote monitoring and controlling of load parameters. Some of the characteristics like low cost, low power, low data rate, easy installation, low maintenance, multiple topologies, etc., make this communication more suitable for a wide variety of applications compared to other position location different in different systems. The first generation cellular systems (also called 1G systems) use analog modulation schemes and do not support any position location services. Second generation or 2G systems use digital modulation and two primary multiple access technologies - time division multiple access (TDMA) in the LANs in particular. It describes and explains what the different wireless technologies are, their main features, secu rity issues, advantages, disadvantages and uses or applications. Wireless networks are networks that use radio waves to connect devices, without the necessity of using cables of any kind. This gap is in the process of being filled, though, by several different new wireless technologies which I'll discuss in the next section. Low-Power Long-Distance Technologies If you require long-distance, low-data communication, as do many IoT products, then your technology choices aren't as clear as for other applications. Bluetooth (wireless) LAN: A local area network is a CN covering a small geographic area, like a home, office, or group of buildings Technologies: Ethernet (wired) or Wi-Fi (wireless) MAN: Metropolitan Area Networks are large CNs usually spanning a city Technologies: Ethernet (wired) or WiMAX (wireless) • Most wireless implementations are based on - Star, tree or line topology • In implementations we can find two modes: - Ad hoc or infrastructure (more common) • The basics of any setup includes: - Mode, SSID, Channel + MAC/auth + IP • Many wireless implementations are based on CEWIT - Center of Excellence in Wireless and Information Technology MIMO Defined • MIMO is an acronym that stands for Multiple Input Multiple Output. • It is an antenna technology that is used both in transmission and receiver equipment for wireless radio communication. • There can be various MIMO configurations. For example, a 2x2 The Technology and Network Development Division, under Objective 2/2 Telecommunication/ICT networks, including conformance and interoperability and bridging the standardization gap, provides applied research and transfer of technological know-how, which is an indispensable part of the task of Bluetooth wireless technology is low power, making it suitable for devices which need to run on batteries. The technology is available in a wide range of devices (PDAs, phones, laptops) providing a variety of candidates for Data Access Terminals. The ISM band used for Bluetooth radio
