Distributed Antenna Systems (DAS)

With data consumption rising rapidly and the population expanding too, it can be difficult for mobile network operators (MNOs) to keep up with the demand for wireless connectivity.

People expect to be able to make voice calls and access 3G and 4G mobile data wherever they go, but high-footfall venues and areas such as conference centres, sports stadiums and large shopping centres are prone to becoming connectivity black holes, where insufficient capacity or coverage causes constant frustration for visitors and staff.

Thankfully, this is an issue that can be solved with the help of Distributed Antenna Systems – or DAS.

What is a Distributed Antenna System (DAS), and how does it work?

A Distributed Antenna System is a network of antennas that can be installed throughout a building or outdoor area to enhance mobile coverage for the benefit of users inside and nearby.

These relatively small antennas are linked via remote units to a central control point, which in turn is physically connected to mobile network operators’ base stations nearby. The result is a stronger and more reliable mobile signal for customers of all operators.

A DAS can be scaled easily, and can therefore cater for multi-storey buildings of all shapes and sizes. A typical setup would involve an equipment room on each floor of the building being used to house remote units, which then distribute via their own set of intelligently placed antennas. If the building only has one level, the arrangement becomes even simpler.

Why use a Distributed Antenna System (DAS)?

Most modern buildings are constructed with eco-friendliness in mind, but the materials used for insulation can prevent mobile frequency coming in. This is why it’s essential to have dedicated equipment inside, rather than rely on repeated external signals.

Small Cells may be another option for enhancing coverage and capacity, but this technology is typically suited to smaller venues and won’t be as effective in large spaces such as stadiums and conference centres. With today’s small cells you’ll need to deploy them separately for each mobile operator, whereas DAS mixes the signal and deploys them over the single antenna system.

So, given the scalability of a DAS, and the fact that it’ll be powered directly by a mobile operator base station, this is by far the best solution for delivering capacity and coverage in a large venue.

The results

With an expertly installed DAS in place, it’s possible to provide a strong and reliable mobile signal for customers of all mobile network operators. This ensures you’re able to optimise the visitor experience for people who expect to be able to use their connected devices wherever they go. Expect higher dwell times, and increased investment interest as a result.

In-Building solutions like DAS are already highly valuable to landlords and mobile network operators, but their importance will only grow in the coming years as 5G starts to become available and mobile data consumption continues to grow. Now’s the time to invest.
