Measurement of the weakest signal that a wireless receiver can receive and still translate into data. Receiver sensitivity is affected greatly by a number of factors, including location and placement within the wireless device.
Industry:Technology
The description for an operating system that responds to an external event within a short and predictable time frame. Unlike a batch or time-sharing operating system, a real-time operating system provides services or control to independent ongoing physical processes. It typically has interrupt capabilities (so that a less important task can be put aside) and a priority-scheduling management scheme.
Industry:Technology
An approach to large-scale application development (AD) that includes the following phases, which are executed by up to 10 teams of 10 people each during a period of no more than 18 months:
• Phase 1: Business and technical architecture reconciliation.
• Phase 2: Functional requirements gathering and specification.
• Phase 3: Initial architecture design, building and implementation.
• Phase 4: First building and testing of application, including user interface, data access and business logic.
• Phase 5: Initial installation of application.
• Phase 6: Concurrent engineering for subsequent builds.
• Phase 7: Rapid release plan.
Industry:Technology
An application development (AD) approach that includes small teams (typically two to six people, but never more than 10) using joint application development (JAD) and iterative-prototyping techniques to construct interactive systems of low to medium complexity within a time frame of 60 to 120 days.
Industry:Technology
Radio frequency identification (RFID) refers to an automated data collection technology that uses radio frequency waves to transfer data between a reader and a tag to identify, track and locate the tagged item. There are two basic categories of tags used for logistics and transportation: passive and battery-enabled. Passive tags collect the necessary energy from the antenna of the reader, which can be fixed or portable. Battery-enabled tags fall into two major groupings: battery-assisted passive (BAP) technology and active RFID tag technology.

PAD with an integrated radio transceiver for use with packet radio systems.
Industry:Technology
Plays a role similar to the BSC in a GSM network, but supports B nodes used in UMTS networks.
Industry:Technology
A standard increment used to express the height of a piece of rack-mounted computer or networking equipment, abbreviated as “U” and equal to 1.75 inches. For example, a server with a height of 4U takes up seven inches of vertical rack space. The most common dimensions for an industry-standard rack are 42U (73.5 inches) high and 19 inches wide.
Industry:Technology
• Rack mountable — A system that can be mounted in a rack or as a stand-alone
• Rack-Optimized — A system that has to be run in a server cabinet
• Tower/stand-alone — A system optimized for stand-alone installation only
• Blade — A discrete CPU card that slides vertically into a shared chassis. Typically several blade cards are housed in a cabinet or a stand-alone chassis, which houses a common power supply, cooling element, and network switches and connections.
Industry:Technology
The rack density describes the height of a unit. The standard height of one unit is 1.75 inches, so rack density is described in terms of the number of units, such as one unit (1U), 2U and so on. Blade servers are noted as “number of blades per blade chassis/height” (in standard U height), so 14 blades per blade chassis height of 7U would be listed as “14/7U.”
