Shared Bandwidth
Most residential broadband technologies, such as FTTX, Satellite Internet, or WiMAX, a population of users share the available bandwidth. Some technologies share only their core network, while some including Cable Internet and PON also share the access network. This arrangement allows the network operator to take advantage of statistical multiplexing, a bandwidth sharing technique which is employed to distribute bandwidth fairly, in order to provide an adequate level of service at an acceptable price. However, the operator has to monitor usage patterns and scale the network appropriately, to ensure that customers receive adequate service even during peak-usage times. If the network operator does not provide enough bandwidth for a particular neighborhood, the service can become sluggish if many people are using the service at the same time. Operators have been known to use a bandwidth cap, or other bandwidth throttling technique; users' download speed is limited during peak times, if they have downloaded a large amount of data that day.

Famous quotes containing the word shared:
“Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?”
—Ernest Renan (1823–1892)
