Are green building materials blocking mobile phone signal in your workplace?

Does bad mobile phone signal ever drive you or your colleagues up the wall? Funnily enough, it might actually be materials in the walls that are blocking mobile phone signal, preventing it from penetrating indoors and making it impossible to make or receive phone calls inside.

With sustainability the ‘hot button’ topic of the moment, choosing a workplace that complies with green standards – such as the Building Research Establishment Environmental Assessment Method (BREEAM) – is undoubtedly important. But that doesn’t mean every time you want to make a phone call you should have to trek to the one part of your building with mobile phone signal, or exit your office entirely.

Below, we highlight the material seen as one of the biggest issues for mobile phone signal - Low-E glass – and explain what you can do to boost mobile signal in your building.

What is Low-E glass?

Low-E glass (or low-emissivity glass) features a thin metallic coating sprayed onto it at high temperatures. It’s designed to prevent heat escaping out through windows, making it particularly attractive for buildings in colder climates.

However, as well as stopping energy from passing out, Low-E glass also reflects mobile phone signals from masts and prevents them from penetrating inside the building. As a result, occupants of the building might get no bars on their phone, meaning they can’t make or receive phone calls or browse mobile internet.

Low-E glass isn’t the only green construction element that impacts mobile phone signal. According to a study from telecoms regulator Comreg, foil-layered insulation can reduce signal by between 15 and 60dB.

Other major disruptors of mobile phone signal include metal, stone, brick and tile – if your office features these materials in abundance, they may be blocking your internal communications.

So what’s the answer?

With a smart mobile phone signal booster solution from Cel-Fi, you can allow mobile phone signal to bypass hard-to-penetrate construction materials entirely using a network of indoor antenna systems.

An external antenna can be set up wherever mobile phone signal is strongest. Mobile phone signal is boosted using an internal amplifier and fed indoors via a cable to an indoor antenna. This can be stretched out across your building’s interior, giving you reliable coverage so your staff get bars on their phone, wherever they are.

Cel-Fi products are the perfect fit for your environmentally conscious building. You’ll be able to benefit from increased energy efficiency and green credentials, while ensuring your staff can contact clients and loved ones, access mobile internet on 3G and 4G and stay connected.
