Ditch the Dead Zones: Signal Boosters vs. Wi-Fi Calling, Mesh, and More!

At Signal Solutions, we specialise in installing mobile signal boosters across the UK and Europe, helping businesses and individuals overcome connectivity issues. But how do signal boosters compare to other connectivity solutions like Wi-Fi calling, mesh networks, or small cells? And more importantly, which is the right solution for you? Let’s break it down.

What Are Signal Boosters?

Signal boosters are designed to enhance existing mobile signals, improving coverage and call quality in areas where signal strength is weak. They work by capturing the outdoor signal, amplifying it, and redistributing it inside the building, ensuring better connectivity for all users.

Why do signal boosters matter?

  1. Ideal for areas with weak signal, such as rural locations, buildings with thick walls, and high-rises.
  2. Enhance all network providers, making them a universal solution.
  3. Future-proof, working seamlessly with 4G and 5G networks.
  4. No reliance on Wi-Fi, which can fail or drop out – just a strong and stable mobile signal, even in emergencies.

For businesses, hotels, and offices, signal boosters provide an efficient and scalable solution that guarantees improved connectivity without relying on broadband.

Alternative Connectivity Solutions

While signal boosters are highly effective, there are other solutions people consider when trying to improve their connectivity. Let’s take a look at some common alternatives and how they compare.

Wi-Fi Calling

Wi-Fi calling allows users to make calls over a wireless internet connection rather than using the mobile network.

  • Pros: Works well in areas with strong broadband; easy to enable on most modern smartphones.
  • Cons: Requires a stable and fast internet connection; if the Wi-Fi drops, so does your call.

Mesh Networks

A mesh network extends Wi-Fi coverage by using multiple routers to create a seamless network.

  • Pros: Great for boosting Wi-Fi coverage in large homes or offices.
  • Cons: Doesn’t improve mobile signal; dependent on broadband performance.

Small Cells

Small cells act like mini mobile masts to provide coverage in a specific area.

  • Pros: Can improve mobile signal in a small area; used by major network providers.
  • Cons: Expensive; requires network approval; not always an option for individual businesses.

VOIP (Voice Over Internet Protocol)

VOIP services like Microsoft Teams, Zoom, and Skype allow users to make calls over the internet.

  • Pros: Can work well for businesses with reliable internet.
  • Cons: Heavily dependent on broadband speed and quality; not suitable for emergency calls.
