Like it or not, dropped calls are still a major problem for a large number of people, and while the carriers are continuing to add towers and expand coverage areas, this is not a problem that’s going to go away soon. A recent survey by the Pew Internet and American Life project found that 72% of Americans experience some form of dropped calls, and 32% experience dropped calls at least a few times per week or more. Losing signals in commercial office building has been an issue since the handheld cellular device came on the market. DAS systems may be tied to a particular wireless carrier, such as AT&T or Verizon, but the best bang for your buck is a neutral-host provider that can work with multiple carriers.
Their size and power requirements also allow their installation in areas where traditional cell towers cannot be placed due to zoning restrictions. Because DAS antenna node installations are compact, they can be deployed indoors and outdoors. In short, this type of configuration introduces efficiency into the system that wouldn’t otherwise be there, and thus results in less power being used. To overcome these feeder losses, a DAS can use either a configuration of passive splitters and feeders, or active-repeater amplifiers.
Providing cellular signals is a power hungry task, often because of signal losses due to penetration and shadowing. 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. A distributed antenna system (DAS) is a network of spatially or geographically separated antenna nodes.
