Frequency Hopping Spread Spectrum FHSS (FrequencyHoppingSpreadSpectrum) A method of spreading frequencies in which signals are hopped between channels. If a channel is interfered with, it can be skipped.GenericToken Card (GTC) User authentication in a cryptographic tunnel.Group Temporal Key GTK (Group Temporal Key) is generated from GMK random numbers. This key changes on timeout or when the user leaves the network. Group Transient Key GTK (Group TYansientKey) is commonly used to decrypt broadcasts and multicasts.Hertz Hz (Hertz) is used to measure bandwidth. Hertz measures the number of cycles per second.Hidden nodeissue When multiple clients try to send signals on the same channel at the same timewhen they are all within range of the AP, but cannot reach each other.372 Appendix B Glossary of TermsGSM (Global System forMobileCommunication) A digital mobile telephone system that uses a variant of time-division multiple access (TDMA, time-divisionmultipleaccess). GSM is one of the three most widely used digital radio telephony technologies (TDMA, GSM and CDMA). GSM operates in the 900 MHz or 1800 MHz band. Group Master Key GMK (GroupMasterKey) is used by the AP to generate a group random number.hidden nodeproblem A problem that occurs when two devices cannot communicate with each other. horizontal planeM-Plane The horizontal plane of an omnidirectionally polarized antenna, as opposed to the E-plane. horizontal polarizationThe wave advances left and right in a linear fashion.
