The IEEE standard that specifies a carrier sense media access control and physical layer specifications for wireless LANs. The subcategories include 802.11b for 5.5 and 11 megabit per second performance, and 802.11a for 54 megabit per second performance. The traditional method of modulating radio signals so they can carry information. A fraud prevention technology that takes a number of values to create a shared, secret value used to verify a user's authenticity. Bandwidth Refers to the amount of data a set of frequencies can carry at one time.
Greater bandwidth means less distortion and higher throughput on a transmission medium.
Describes a communications medium capable of transmitting a relatively large amount of data over a given period of time. The throughput of the medium per unit of time is measured in kilobits, megabits, or gigabits per second. Broadband transmission often implies transmission of 128 kilobits per second or greater. A device that plugs into a cable network to provide Internet access to homes or small businesses. Digital A method of encoding information using a binary code of 0s and 1s.
