A distributed antenna system (DAS) is a way to deal with isolated spots of poor coverage inside a large building by installing a network of relatively small antennasthroughout the building to serve as repeaters.
The antennas are physically connected to a central controller which is connected to the wireless carrier network’s base station. Because distributed antenna systems operate on RF spectrum licensed to wireless carriers, an enterprise cannot undertake a DAS deployment on its own without involving at least one carrier and incorporating it with iBwave.
Distributed antenna systems are transparent to mobile devices, providing both voice and data services to mobile devices just like any tower on a cellular network. Densely populated indoor spaces such as shopping malls, medical centers and high-rise buildings are all good candidates for DAS deployments.
Distributed antenna systems can be passive or active.
These systems can be set up in large buildings and campuses by converting and transporting the radio frequencies over optical fiber. They may be deployed to cover large areas. They are best suited when there is a need to support multiple mobile network operators.
In a properly designed active system, no re-engineering or rebelling of the original system is required when the system is expanding, thus meaning that they are flexible when adding 3G, 4G or LTE services. Furthermore, active systems utilizing optical fiber can provide coverage in areas up to 2km from the signal source making them ideal for campus environments.
The active system is similar to the passive system, except that instead of regular feeder cables, the active distributed antenna system passes the signal from the roof to fiber cables. In the active system, the fiber cables give the signals a boost and amplification along the way. This leads to faster and stronger wireless capabilities for your building.
Whether passive or active, a distributed antenna system will cover many subscribers while also filling service gaps from your wireless provider. As a result, you will experience stable and reliable cellular service. The distributed antenna system will improve your buildings’ reliability to radio frequencies from fire departments, police, and different types of first responders for the safety of your property and building occupants.
