Classification and Advantages of Distribution Antenna Systems

Introduction to Distribution Antenna Systems

A Distribution Antenna System (DAS) is a mobile communication network formed within a predetermined space or building. It consists of multiple spatially separated antenna nodes that are connected to multiple signal sources through various signal transmission media. Distribution antenna systems can be deployed indoors (iDAS) or outdoors (oDAS), and can be customized and upgraded based on requirements.

Categories of Distribution Antenna Systems

Indoor Distributed Antenna System (iDAS)

Indoor distributed antenna systems are primarily suitable for buildings with weak or no mobile signal coverage. This includes users who are within the mobile signal coverage area but are unable to use the mobile network (for making calls, sending texts, or accessing the internet) due to network capacity limitations.

Outdoor Distributed Antenna System (oDAS)

Outdoor distributed antenna systems are mainly suitable for densely populated areas where signal towers cannot be erected (such as ancient towns and scenic spots) and areas that require centralized network management and real-time monitoring (such as government agencies, campuses, and industrial bases).

Advantages of Distribution Antenna Systems

In the early stages of cellular communication development, in-building wireless coverage (IBS) was not a primary concern. By the mid-2000s, with the advent of 3G and 4G technologies, the demand for reliable in-building coverage significantly increased. With the introduction of 5G and 6G, this demand continues to grow. DAS solutions address these challenges by enhancing network coverage and capacity in areas where the macro network cannot adequately meet the demands. This may be due to high penetration loss of building materials, low transmittance glass, or building structures that block signals. Numerous ongoing simulations regarding in-building solutions help address the complexities of indoor 5G coverage.

Distribution Antenna Systems (DAS) are a common solution for improving mobile communication coverage. This approach involves deploying an antenna network throughout the building, distributing the signal from a central location. There are several types of distribution antenna systems, including passive distribution antenna systems, active distribution antenna systems, hybrid distribution antenna systems, and digital distribution antenna systems. Each type of distribution antenna system has its advantages and limitations depending on the size and nature of the site.
