  • Hot Spot 2.0 (HS 2.0)

    Hot Spot 2.0 (HS 2.0), also called Wi-Fi Certified Passpoint, is a new standard for public-access Wi-Fi that enables seamless roaming between WiFi and cellular networks. HS 2.0 is based on a set of protocols called 802.11u, which facilitates cellular...  Definition

  • Apple Bonjour

    Apple Bonjour is a group of networking technologies designed to help devices and applications discover each other on the same network.  Definition

  • pervasive computing (ubiquitous computing)

    Pervasive computing (also called ubiquitous computing) is the growing trend towards embedding processors in everyday objects so they can communicate information.  Definition

  • 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.  Definition

  • 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....  Definition

  • wireless mesh network (WMN)

    A wireless mesh network (WMN) is a mesh network created through the connection of wireless access points installed at each network user's locale.  Definition

  • beamforming

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

  • 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)  Definition

  • radio frequency (RF, rf, orr.f.)

    Radio frequency (abbreviated RF, rf, orr.f.) is a term that refers to alternating current (AC) havingcharacteristics such that, if the current is input to an antenna, an electromagnetic (EM) field is generated suitable for wireless broadcastingand/or...  Definition

  • 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.  Definition
