Distributed Antenna Systems

Signal source 

The process starts with a central signal source, which can be a wireless carrier network, a satellite feed, or a broadband connection. This source provides the initial signal that the DAS will distribute.

Distribution 

The central signal is then fed into a DAS headend or hub. This hub acts as the control centre for the system, managing and processing the signal before distributing it. In some systems, signal amplifiers are used to boost the strength of the signal.

Network of antennas 

From the hub, the signal is distributed to a network of strategically placed antennas. These antennas are smaller than traditional cell towers and are distributed throughout the coverage area, which can be a building, a campus, or an outdoor space. The placement and number of antennas are crucial for ensuring consistent coverage.

Signal transmission 

The antennas transmit the signal to and from user devices. In a building, these antennas can be installed in ceilings, on walls, or other discreet locations to ensure a wide and effective coverage area.

Support for multiple mobile networks

Modern DAS are typically mobile network agnostic and can support multiple frequencies, allowing them to handle signals from different communication providers and other wireless services simultaneously.

(1) Improved network coverage 

DAS effectively addresses the issue of poor mobile network reception inside large buildings. By distributing signal coverage throughout the structure, it ensures that employees, customers, and visitors have consistent and reliable mobile service coverage, regardless of their location within the building.

(2) Enhanced data capacity 

With the increasing use of smartphones and mobile data, DAS can significantly improve data capacity. This is crucial for businesses that rely on mobile data for operations, such as hotels, shopping centres and office buildings, where a large number of users may be accessing data services simultaneously.

(3) Scalability and flexibility 

DAS is scalable and can be tailored to the specific needs of a building or campus. As the business grows or changes, the system can be adjusted to accommodate new areas or increased capacity demands without a complete overhaul of the infrastructure.

(4) Better user experience 

For businesses that depend on customer satisfaction, such as retail or hospitality, having a reliable mobile signal is crucial. DAS ensures that customers can stay connected, which can enhance their overall experience and potentially lead to increased business.

(5) Support for emergency services 

In the UK, ensuring reliable communication for emergency services is critical. DAS can support public safety communications systems, ensuring that emergency responders can maintain communication in critical situations, especially in areas where radio signals might otherwise be weak or non-existent.

These advantages make DAS an essential consideration for UK businesses looking to improve their in-building wireless communication capabilities, customer satisfaction, and operational efficiency.
