Distributed Antenna Systems (DAS) are wireless communication systems that use multiple antennas to provide coverage in areas where traditional cell towers are not enough. They are used to boost signal strength in locations where it is difficult to get a strong signal due to physical obstacles or high-density usage. Keep reading to learn more about DAS systems.
Components of DAS Systems
DAS systems are made of two major components:
A Single Source
A distributed antenna system (DAS) requires a single source of radio frequency (RF) signal, which is typically provided by a base station or a macrocell. The base station or macrocell is the source of the RF signal, which is then distributed throughout the DAS using the other components of the system.
Distribution System
The distribution system is used to transmit the RF signal from a single source throughout the DAS. It consists of fiber optic cables, coaxial cables, amplifiers, splitters, and other components needed to distribute the signal. The distribution system is typically responsible for providing power and signal to all of the antennas throughout the DAS.
Performance Metrics: Coverage vs. Capacity
DAS is used to improve the coverage and capacity of cellular networks. The performance of a DAS can be measured using two metrics: coverage and capacity.
Coverage is a measure of how well the DAS is providing service to all of the users within the coverage area. This metric is typically measured by testing the signal strength, noise levels, and throughput at various locations within the coverage area. The DAS should be able to provide good signal strength and low noise levels in order to provide reliable coverage.
Capacity refers to how much data the DAS can handle at any given time. You can measure the capacity by testing the rate of data throughput (in bits per second) at various locations within the coverage area. The DAS should be able to handle higher data throughputs in order to provide a better user experience.
By monitoring these two metrics, it is possible to determine how well the DAS is performing and make adjustments as necessary.
Benefits of DAS Systems
Improved Coverage
Installing a DAS allows for improved coverage and signal strength in an area that would otherwise be weakened by obstacles such as walls. This is because DAS systems are designed to act as an extension of the main cellular network, allowing signals to be transmitted more effectively over a larger area. Additionally, DAS systems can be tailored to cover specific areas, such as a building, a campus, or an outdoor event.
Reduced Interference
By providing multiple antenna nodes in an area, a distributed antenna system can reduce interference and improve network performance. This is because multiple antennas can be used to minimize co-channel interference and increase network capacity. Moreover, multiple antennas can be configured to reduce interference from other networks or technologies, such as WiFi or Bluetooth. This helps ensure that users have the best possible experience when using their mobile devices.
Increased Capacity
Since they provide multiple antenna nodes in an area, DAS can increase the capacity of a network. This is because multiple antennas can be used to increase the number of users that can access the network at a point in time.
