Infrastructure wireless LANs. Networking and Internet services are essential requirements for today’s business computing. Mobile Computing; Types of Wireless networking technology and Comparison. These mobile users require connectivity to a network, regardless of where they are because they want simultaneous access to the network. The terms "mobile" and "wireless" are often used interchangeably but in reality, they are two very different concepts applied to modern computing and technology. An increasing number of LAN users are becoming mobile. MOBILE COMPUTING Wi-Fi Wi-Fi • Wi-Fi: • Wireless Local Area Network Wireless LAN Applications Wireless LANs are applicable to all industries with a need for mobile computer use or when the installation of physical media is not feasible. Most companies, public hotspots, and homeowners implement infrastructure WLANs. At present, the usage of mobiles has been increased for different requirements like the internet, talking, multimedia, gaming, photos, video capturing, etc. Wireless Risks • Wireless – all of the above concerns plus an increased risk of eavesdropping (and transmitting). A mobile device is one that is made to be taken anywhere. WLAN Uses. 0. An infrastructure WLAN, as shown in Figure 3-2 , offers a means to extend a wired network. 802.11n also offers a somewhat better range over … A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. By. Using wireless communication services, we can transfer data, voice, images, videos, and many more. 802.11n . WLANs aim to support truly mobile work stations. Industry standards groups ratified 802.11n in 2009 with specifications providing for up to 600 Mbps of network bandwidth. There are basically three different types of wireless networks – WAN, LAN and PAN: Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals typically provided and maintained by specific mobile phone (cellular) service providers.WWANs can provide a way to stay connected even when away from other forms of network access. All these services are available on mobile. Er Parag Verma-Feb 23, 2016. wireless LAN (WLAN or Wireless Local Area Network): A wireless LAN (or WLAN, for wireless local area network, sometimes referred to as LAWN, for local area wireless network) is one in which a mobile user can connect to a local area network ( LAN ) through a wireless (radio) connection. The wireless networking use radio waves and/or microwaves to maintain communications in among devices of sender and receiver such as laptops to the Internet, the business network and applications. Wireless computer networks are capable of offering versatile functionalities. Need for Wireless LANs. Mobile Terminals (MTs), on the other hand, are more powerful, and can be accessed when they are in motion. Only need to be “nearby.” –Depending on the wireless technology, nearby can be line-of-sight, same room, outside a building, within a few miles MOBILE COMPUTING Vs WIRELESS NETWORKING . This gives users the ability to move around within the area and remain connected to the network. WLANs are very flexible and can be configured in a variety of topologies based on the application. Below are some of the most common types of Wireless and Mobile Device Attacks: SMiShing : ... is a security protocol that attempted to provide a wireless local area network with the same level of security as a wired LAN. Types of Wireless Communication. In this configuration, one or more access points interface wireless mobile devices to the distribution system. –No need to tap or plug into the network. 802.11n (also sometimes known as Wireless N) was designed to improve on 802.11g in the amount of bandwidth it supports, by using several wireless signals and antennas (called MIMO technology) instead of one. View Lecture5-WiFi1.pptx from COMPUTER S 432 at CECOS University of Information Technology and Emerging Sciences, Peshawar. 6605. Mobile is a word that is commonly used to describe portable devices.
