Gartner delivers technology research to global technology business leaders to make informed decisions on key initiatives.
The component of a computer system that controls the interpretation and execution of instructions. The CPU of a PC consists of a single microprocessor, while the CPU of a more powerful mainframe consists of multiple processing devices, and in some cases, hundreds of them. The term “processor” is often used to refer to a CPU.

Cellular to Wi-Fi authentication provides the ability for dual-mode smartphones to move freely between cellular and Wi-Fi connectivity for voice and data applications. As part of the 802.11u standard, this multivendor and multiple physical layer authentication allows cellular connections to be transferred to Wi-Fi, as well as among multiple Wi-Fi vendors from one installation to another, whether it is a hot spot or, ultimately, within an enterprise.
Industry:Technology
Cellular radio describes a method of increasing the number of simultaneous radio conversations that can be supported by a fixed number of radio frequency (RF) channels by limiting the range of transmitters to a single cell, to which a proportion of the available channels is allocated. Adjacent cells are allocated to a different set of RF channels to avoid interference and conversation blocking. Frequencies can be reused in cells at intervals sufficient to avoid interference.
Industry:Technology
A heterogeneous server technology from Unisys that can run any combination of operating systems.
that are part of more comprehensive facilities management or network planning applications.
Industry:Technology
Cell splitting is a means of increasing the capacity of a cellular system by subdividing or splitting cells into two or more smaller cells.
Industry:Technology
A cell site is defined as the entire set of equipment needed to receive and transmit radio signals for cellular voice and data transmission; typically includes transmitters, receivers, power amplifiers, combiners, filters, a digital signal processor, a power supply and network interface modules.
Industry:Technology
A 2.5G transmission technology; an evolution of cdma2000 that adds voice capacity and supports peak downlink data rates of up to 144 Kbps in a single 1.25MHz channel, typically delivering 80 Kbps to 100 Kbps in the field.
Industry:Technology
Cdma2000 is the commercial name for the IMT-2000 CDMA Multicarrier (MC-CDMA) standard developed through the 3GPP2 standards organization of the ITU. It is an evolving family of cellular networking specifications that offers enhanced voice and data capacity over cdmaOne. The family includes 1xRTT, EV-DO, EV-DO Rev. A, EV-DO Rev. B and EV-DO Rev. C.

C-band refers to the portion of the electromagnetic spectrum allotted for satellite transmissions in the 4GHz to 8GHz frequency range. C-band satellite antennas are used frequently in areas of the world where signals can become degraded due to heavy rain or other intense climate-related conditions. As a rule, C-band satellite antennas range in size from 1.8 meters to 2.4 meters. C-band satellite communications suffer less from rain attenuation, but they require larger antennas and typically are used in Asia, Africa and Latin America. See also antenna, frequency bands, Ka-band, Ku-band and satellite dish.

The entire category management process facilitates fact-based selling by providing analytics from a retailer’s as well as a manufacturer’s perspective so that the mutual value of the business proposition can be known. Considerations include product assortment, pricing, promotion, placement, timing and, to some degree, packaging. The IT component is the automation of data loads and data manipulation, as well as the presentation of results in a compelling way, following an agreed-on business process. The IT enablement is typically a demand signal management repository.
