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
