What is distributed antenna systems and how are they important?
Distributed antenna systems are a network of antennas distributed throughout an area to enhance network performance. This antenna network is robust compared to a single, large antenna that covers a wide area. Read on for more information about the importance of distributed antenna systems and how it allows contact with forces responding to buildings in the process of being damaged.
What is a Distributed Antenna System?
A distributed antenna system (DAS) is designed for indoor or outdoor use and provides wireless coverage in subways, hospitals, hotels, businesses, roadway tunnels, etc. In addition, these wireless services are generally provided by a DAS consisting of cellular, Wi-Fi, fire, police, or emergency services.
In addition, distributed antenna systems assist responders in keeping constant radio contact with others during emergencies. These systems are critical for emergency response situations because clear communication affects rescue efforts.
What Are the Types of Distribution Systems?
Furthermore, there are four distribution systems: active (it uses fiber optic or ethernet cable), passive, hybrid, and digital.
- A passive distributed antenna system uses passive components like splitters, tapers, and coaxial cables to distribute signals inside a building. In addition, this system manages the wireless signals through “leaky” feeder cables that perform as antennas within the building.
- An active DAS system transforms the analog RF signal into a digital signal for distribution. After the conversion, the digital signal is transmitted through fiber optic or Ethernet cables to the antenna systems.
- Another type of distribution system is a hybrid DAS system. This system uses coaxial and fiber optic cables to spread the signal around a building.
- Lastly, the digital DAS communicates directly with the DAS master unit and around the remote units without any transformation to an analog RF interface.
Pros and Cons of Using Distributed Antenna Systems
Moreover, some common advantages of using distributed antenna systems include an enhanced defined coverage, fewer coverage holes, same coverage using less power, and the individual antennas do not require to be high as a single antenna to receive the equivalent coverage.
In contrast, the common disadvantages of using distributed antenna systems are a potential visual effect in some applications due to a high number of antennas and higher cost due to necessary infrastructure.
