Distributed Antenna System (DAS) Design

Shared Access has been involved in designing Distributed Antenna Systems (DAS) for several years. Our company’s expertise in deploying connectivity solutions in large venues is highlighted by our work on projects such as the Tottenham Hotspur Stadium.

Additionally, we have been active in providing mobile connectivity solutions in various challenging environments, including the Tyne Tunnel and the National Gallery in London.

However, that’s not all we do – we have designed DAS for offices, public spaces and even a marina. So, whatever your connectivity requirements, particularly in-building, Shared Access has a solution for you.

What is a Distributed Antenna System (DAS)?

A Distributed Antenna System (DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium to provide wireless service within a geographic area or structure. It is designed to improve wireless coverage in areas where signal strength is weak due to obstacles or high user density.

What are the Components of DAS Design?

Signal Source

A DAS typically requires a signal source, which can be:

  • Off-air: capturing signals from nearby cell towers using an antenna.
  • On-site Base Transceiver Station (BTS): generating the signal locally.
  • Small Cells: providing localised signal coverage, often used in conjunction with DAS to expand coverage areas efficiently.

Distribution System

The distribution system can be categorised into:

  • Active DAS: uses powered equipment, such as fibre optic or Ethernet cables, to distribute signals. It is suitable for large buildings and high-capacity venues.
  • Passive DAS: utilises passive RF components like coaxial cables, splitters, and couplers. It is cost-effective and simpler but has limitations in performance and coverage.
  • Hybrid DAS: combines elements of both active and passive systems, providing a balance between cost and performance.

DAS Design Considerations

When designing a DAS for your organisation, whether a public space, or a private venue, the process involves several considerations:

  • Coverage area: ensuring the system covers the intended area effectively.
  • Capacity requirements: determining the number of users and the expected data traffic.
  • Building layout: accounting for the architectural features that may affect signal propagation.
  • Regulatory compliance: adhering to local regulations and obtaining necessary approvals.

By conducting a full analysis of your requirements and a full site survey, our perfect planning results in a DAS design that provides peak performance.

Who Designs DAS

Our engineers have many years of experience in designing connectivity solutions, so you’ll benefit from a mixture of telecoms and systems technicians, alongside a robust project management team. We design, build, deploy and maintain your DAS system so that your users can benefit from the huge array of advantages DAS brings.

Importance of DAS

DAS is crucial in environments where traditional wireless coverage is insufficient, such as:

  • High-density venues: stadiums, airports and large office buildings where many users need reliable connectivity.
  • Geographically challenging areas: locations with obstacles like thick walls or underground facilities that impede signal penetration.

Whatever your situation, speak with our team and we will find a solution to ensure you have the very best connectivity, whatever the environment.

The Benefits of DAS

Implementing a DAS brings several benefits:

  • Improved coverage: enhances signal strength and reliability in areas with poor reception.
  • Increased capacity: supports a higher number of users and data traffic, essential for large venues.
  • Enhanced user experience: provides seamless connectivity, reducing dropped calls and improving data speeds.
  • Scalability: DAS can be scaled to meet the growing demands of users and new technologies like 5G.

In summary, DAS design involves careful planning and consideration of various factors to ensure effective wireless coverage. DAS systems are designed and implemented by specialised professionals and are essential for improving connectivity in challenging environments, offering numerous benefits in terms of coverage, capacity and user experience.
