ISYS EXAM 2: 7.3 (Wireless Network Categories)
wired equivalent privacy (WEP)
an encryption algorithm designed to protect wireless transmission data; not as good as WPA
wireless
any type of operation accomplished without the user a hard-wired connection
hotspots
designated locations where wifi access points are publicly available; restaurants, airports, hotels
wireless MAN (WMAN)
metropolitan area network that uses radio signals to transmit/receive data; not widely successful
IEEE 802.11n (or Wireless-N)
newest standard for wireless networking; faster speeds, more flexibility, greater range; each number-letter denotes different bandwidth
personal area network (PAN)
provides communication for devices owned by a single user that work over a short distance; bluetooth
multiple-in/multiple-out (MIMO) technology
have multiple transmitters and receivers
Voice over LTE
a VoIP call on mobile phone
4 main types of wireless networks
Personal Area Networks (PANs); Wireless Local Area Networks (WLANs); Wireless Metropolitan Area Networks (WMANs), Wireless Wide Area Networks (WWANs)
satellite
a space station that orbits the Earth, receiving and transmitting signals from earth-based stations over a wide area
wireless fidelity (Wi-Fi)
means by which portable devices can connect wirelessly to a local area network, using access points that send/receive data via radio waves
streaming
method of sending audio and video files over the Internet in such a way that the user can view the file while it is being transferred; cellular communication system (WWAN)
war driving
deliberately searching for wifi signals while driving by in a vehicle; controversial; raised awareness for need for secure wifi networks
wireless access point
enables devices to connect to a wireless network to communicate with each other
Wi-Fi Infrastructure
includes inner workers of a wifi service or utility, including signal transmitters, tower, or poles, and additional equipment required to send out signal
2 methods MIS departments use to manage IT consumerization
mobile device management and mobile application management
war chalking
practice of tagging pavement with codes displaying where wifi access is available
mobile device management (MDM)
remotely controls smart phones and tablets, ensuring data security; requires password each time; can wipe entire phone's data remotely
Institute of Electrical and Electronics Engineers (IEEE)
researches and institutes electrical standards for communication and other technologies
mobile
technology can travel with the user; users can download software, email messages, web pages onto laptop or other mobile device for portable reading/reference
access point (AP)
the computer or network device that serves as an interface between devices and network; computer initially connects to [term] then to other computers on the network
wireless WAN (WWAN)
wide area network that uses radio signals to transmit and receive data; divided into cellular communication systems and satellite communication systems
bluetooth
wireless PAN technology that transmits signals over short distances among cell phones, computers, etc.
wifi protected access (WPA)
wireless security protocol to protect wifi networks; improved version of WEP; must know WPA encryption key to access wifi
Worldwide Interoperability for Microwave Access (WiMAX)
a communications technology aimed at providing high speed wireless data over metropolitan area networks; wifi that works over greater distances with higher bandwidth
wireless LANs
a local area network that uses radio signals to transmit and receive data over distances of a few hundred feet
mobile application management (MAM)
administes and delivers applications to corporate and personal smart phones and tablets; limits how sensitive data can be shared among apps
IT consumerization
blending of personal and business use of technology devices and applications
