The drop in power consumption has a slightly more complicated, less intuitive answer.
Well, for one, the mere presence of additional antennas increases the chance of a good line-of-sight channel.
An active DAS takes the wireless signals from an external antenna and passes them to other antennas through fiber cables while being boosted and amplified via a cell phone signal amplifier along the way.Ĭosts for an installed DAS system can range from $1.50 to as high as $3.00 per Square Foot. A passive DAS simply takes wireless signals from an antenna and then runs them through “leaky” feeder cables that act as antennas all over the building the signal leakage distributes the signals. The RF spectrum covered by a DAS is licensed to wireless carriers, so enterprises cannot deploy a DAS on their own and must always involve a carrier, making the deployment the most expensive phase of a DAS project.Ī DAS can be either passive or active.

All of the antennas in a DAS installation are spaced from each other in such a way that each one is able to give full coverage without much overlap with the coverage areas of other antennas, minimizing the number of antennas required to cover a specific area.Īll of the antennas in a DAS are simply extenders for signal coverage and are connected to a central controller that, in turn, is connected to a carrier’s base station. A DAS Network can be deployed indoors to provide network or cellular connectivity throughout a building or outdoors in areas where regular wireless coverage does not reach.Ī distributed antenna system is a way to extend the coverage of a given network such as a cellular network or wireless computer network. These nodes are connected to a common source through a transport or communication medium in order to provide wireless communication service in a specific locality or building. Read the Consumer Advisory for consumers who own signal boosters.A distributed antenna system (DAS) is a network of spatially or geographically separated antenna nodes. New FCC rules for wireless signal boosters came into effect on March 1, 2014. The FCC issued a Report and Order on February 20, 2013, that includes rules and policies that will enhance wireless coverage for consumers, particularly in rural, under-served, and difficult-to-serve areas by broadening the availability of signal boosters while ensuring that boosters do not adversely affect wireless networks. Signal boosters can also improve public safety communications by enabling the public to connect to 911 in areas where wireless coverage is deficient or where an adequate communications signal is blocked or shielded.
Signal boosters are particularly useful in rural and difficult-to-serve indoor environments, such as office buildings and hospitals. Robust signal boosters can bridge these gaps and extend coverage at the fringe of service areas. population is served by one or more wireless providers, coverage gaps that exist within and at the edge of service areas can lead to dropped calls, reduced data speeds, or complete loss of service. Mobile voice and mobile broadband services are increasingly important to consumers and to our nation’s economy. Signal boosters represent a cost-effective means of improving our nation’s wireless infrastructure. Robust Wireless Service at Home, at Work, and on the Road
