microcell

[′mī·krə‚sel]
(cell and molecular biology)
A micronucleus within a layer of cytoplasm and a membrane.

microcell

(1) A geographic area covered by a cellular carrier, generally no more than a mile and a half in diameter. Microcells are used in cities and other densely populated venues. The smaller "picocell" reaches approximately 600 feet, whereas the traditional high-power "macrocell" tower can cover an area as large as 20 miles in diameter or more. See cellphone.

(2) (MicroCell) An indoor cellular tower from AT&T. See femtocell.

Differently than [24-26] however, this paper provides a novel analytical framework for performance evaluation of FFR-aided networks using PPP that is more compatible to modern practical deployments using directional antennas at the macrocell, without resorting to scenario-specific, extensive system-level simulations as in [8-14].

The OCTEON Fusion-M family is a scalable architecture that ranges from the single chip CNF75xx macrocell to the single chip CNF74xx for use in Smart Radio Heads.
Until now, when one femtocell was near either another femtocell or an outdoor macrocell base station, radio wave interference would distort communication signals.
Successful Trial of Wi-Fi at Macrocell Range Over TV White Space Opens Doors to Numerous Commercial Applications: Technology Available for Immediate Field Trials
The BelAir100SP enables mobile carriers and cable operators to extend this relationship to enable widespread picocell deployments that enhance the capacity of 3G and LTE macrocell coverage.
The company said its expanded 3G/4G/long-term evolution (LTE) processor family includes the Transcede 3000, designed for small-cell 3G and 4G base stations supporting up to 32 users, and the Transcede 4005, designed for 3G and 4G macrocell developers who want to combine its high-performance Layer 1 (L1) physical-layer (PHY) processing capabilities with an existing Layer Two (L2) media access control (MAC) processing solution.
Macrocell current, free chloride content, chloride ion penetration depth and rapid chloride penetration tests were carried out to ascertain the performance of concrete specimens.
Features include a fully connected logic array where each array input is available to every product term; selectable registers where each flip-flop can be configured as either a T- type or D- type; buried combinatorial feedback where the Q2 register in any macrocell may be bypassed to feed the input back to the logic array; selectable synchronous/asynchronous clock of any of the flip-flops which allows the registers to use any clock; 48 registers created from two flip-flops per macrocell, each with its own clock and reset and sum terms; and macrocell combinable sum terms where each macrocell's three sum terms may be combined into a single term.
Hierarchical microcell/ macrocell architectures have been proposed [Byungchan 2001, Bo 2001, Chung 2005, Iera 2002, Liu 2005, Li2001, Mar 2000, Shan 2003, Zhao 2005] to increase the traffic-carrying capacity and circuit quality.
The macrocell current density (i, which refers to the current flow between the top and bottom steel mats) is a good indicator of corrosion performance.
Also, the results showed that negligible macrocell current between the top and bottom mats of steel bars was due to bars with few signs of corrosion throughout the nine years of exposure to chlorides.
