Wireless LAN Implementation Definitions

  • #

    802.11a

    802.11a is one of several specifications in the 802.11 family applicable to wireless local area networks (wireless LANs or WLANs).

  • A

    Asynchronous Pulsed Radiated Incident Light

    Asynchronous Pulsed Radiated Incident Light is a multi-duplicitous communication protocol (MDCP) used to configure wireless local area networks (WLANs) on the fly.

  • B

    beamforming

    Beamforming is a type of RF (radio frequency) management in which an access point uses multiple antennas to send out the same signal.

  • bring your own device workplace (BYOD workplace)

    A bring your own work environment (BYOWE) is one that allows -- or even encourages -- employees to use consumer technology for job-related tasks.

  • C

    cognitive radio (CR)

    Cognitive radio (CR) is a form of wireless communication in which a transceiver can intelligently detect which communication channels are in use and which are not, and instantly move into vacant channels while avoiding occupied ones... (Continued)

  • D

    direct sequence spread spectrum (DSSS) or direct sequence code division multiple access (DS-CDMA)

    Direct sequence spread spectrum, also known as direct sequence code division multiple access (DS-CDMA), is one of two approaches to spread spectrum modulation for digital signal transmission over the airwaves.

  • E

    EPOC

    EPOC is an operating system designed for small, portable computer-telephones with wireless access to phone and other information services.

  • F

    frequency-hopping spread spectrum

    Frequency hopping is one of two basic modulation techniques used in spread spectrum signal transmission.

  • I

    i-Mode

    i-Mode is the packet-based service for mobile phones offered by Japan's leader in wireless technology, NTT DoCoMo.

  • iDEN (Integrated Digital Enhanced Network)

    iDEN (Integrated Digital Enhanced Network) is a wireless technology from Motorola combining the capabilities of a digital cellular telephone, two-way radio, alphanumeric pager and data/fax modem in a single network.

  • M

    Mesh Connectivity Layer (MCL)

    Mesh Connectivity Layer (MCL) is a technology that allows a computer user to connect to a wireless mesh network that uses Wi-Fi or WiMax. The wireless mesh network can be connected to the Internet through a single computer using a leased T-1 line or broadband satellite connection, allowing all network users high-speed Internet access.

  • P

    patch antenna

    A patch antenna is a wafer-like directional antenna suitable for covering single-floor small offices, small stores and other indoor locations where access points cannot be placed centrally.

  • phase-locked loop

    A phase-locked loop (PLL) is an electronic circuit with a current-driven oscillator that constantly adjusts to match the frequency of an input signal, often used in wireless systems.

  • R

    radio frequency (RF, rf)

    Radio frequency is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz.

  • S

    software-defined radio (SDR)

    Software-defined radio (SDR), sometimes shortened to software radio (SR), refers to wireless communication in which the transmitter modulation is generated or defined by a computer, and the receiver uses a computer to recover the signal intelligence.
