A
What is the actual radio coverage of a cell that is determined by actual field measurements or propagation models called?
Footprint
Which two cell types are specifically characterized by their small coverage radii and low transmit power for use in indoor environments such as malls, offices, and residential homes?
Picocell and Femtocell
What type of cell is overlaid above a microcell layer to serve fast-moving vehicular users and reduce the rate of handoffs?
Umbrella Cell
What is the total system capacity (C) if a network consists of m=3 clusters, a cluster size of N=7, and each cell is allocated G=100 channels?
2,100 duplex channels
What is the geometric shape used in cellular network modeling because it approximates a circular radiation pattern while tiling an area without gaps or overlaps?
Hexagon
Described as an intermediate stage in the scaling process, these have a radius of roughly 250 m to 1 km and use medium power.
Minicell
The three-tier cell hierarchy that describes how networks scale with subscriber growth. (In order)
macrocells → minicells → microcells
What is the minimum distance between the centres of two co-channel cells
Reuse distance D
This strategy allows the network to maintain a constant co-channel reuse ratio (D/R) while significantly increasing capacity.
Cell Splitting
Cellular approach divides the coverage area into many small regions each called a _____ , each served by a low-power base station (BS).
