Mobile Signal Boosters:

Business Critical Comms Solutions

With over a decade of experience in enhancing business connectivity in the UK, we understand the pivotal role that mobile signal boosters play in corporate buildings that suffer from poor coverage. These solutions, crucial for amplifying weak cell signals, have surged in popularity recently due to the specific challenges posed by commercial building structures.

Commercial buildings are often constructed with signal-impeding materials like concrete, insulation, glass and metals, which can severely disrupt cell signal penetration. This leads to poor reception areas or ‘dead zones’ within these buildings, which are particularly problematic for businesses that depend on mobile communication. In an era where constant connectivity is vital for both internal teams and external users, these dead zones can hinder workflow, client interactions and even emergency communication requirements – increasing risk.

In this article, we’ll be explaining how to overcome the signal-blocking characteristics of modern commercial architecture in smart buildings by either employing a DAS System or a booster. In particular, we’ll cover how mobile signal boosters have become an indispensable tool in our arsenal and how we help businesses achieve seamless connectivity in an increasingly mobile-reliant corporate world.

What are mobile phone signal boosters?

Mobile phone signal boosters are a series of devices (a network) that amplify weak signals within commercial buildings like offices, hospitals, leisure centres, stadiums and similar structures. They capture existing signals from nearby 3G/4G/5G cell towers, enhance their strength with an amplifier and then redistribute the boosted signal indoors through internal antenna, improving call quality and data connectivity.


What causes poor building connectivity?

The primary reasons for poor mobile coverage include:


  • A weak outdoor signal

    This is often attributed to a large distance from the nearest cell towers, which are the primary source of cellular signals. The strength of these signals diminishes as the distance from the tower increases.

  • Building material barriers

    Materials like glass windows and insulation can significantly obstruct mobile signals, even though they are great for sustainability metrics, preventing them from penetrating walls effectively. Buildings in urban areas are often characterised by extremely thick walls, sometimes as much as 1-2 metres, which further impede signal transmission too.

How do commercial mobile signal boosters work?

In commercial buildings, mobile signal boosters are critical to

smart building technology and work like miniature cell towers, amplifying the existing signal received from nearby towers and rebroadcasting it within the building. This helps overcome obstacles like thick walls, metal roofs and distance from towers, creating a zone of enhanced coverage and improving connection quality for employees and customers.


(1) Capturing the signal

The initial step in the mobile signal boosting process involves the strategic placement of an outdoor antenna. We emphasise the importance of positioning this antenna at the highest point of the building. This location is pivotal for maximising signal reception, as it minimises obstructions such as buildings or trees that can interfere with the signal’s path. By elevating the antenna, we ensure a direct line of sight to the nearest cell towers, thus capturing the faintest of signals that are often missed at lower elevations.

(2) Boosting the signal

Once the outdoor antenna successfully captures the signal, the next pivotal phase in enhancing mobile communication within the business is initiated. The captured signal is channelled from the antenna through a specialised cable directly to the signal booster’s core component, the amplifier. This journey is meticulously designed to minimise signal loss, ensuring that the integrity of the received signal is maintained.

(3) Broadcasting the boost

The final, yet equally crucial, stage in enhancing mobile connectivity within a business setting involves the broadcasting of the boosted signal. After the signal has been significantly strengthened by the amplifier, it is ready for distribution within the building. This task is expertly handled by indoor antennas, which are another key component in the signal booster system.

How signal boosters benefit your business


     Mobile signal boosters can greatly benefit your business by:

  • Strengthening weak signals

    Strengthening weak signals is the primary function of mobile signal boosters and they play a crucial role in enhancing business communications. These devices are engineered to detect even the faintest cellular signals emitted from nearby cell towers. Once these weak signals are captured, the booster’s core function comes into play – amplification.

  • Widening coverage area 

    Mobile signal boosters not only amplify the existing weak signals but also by effectively redistributing this enhanced signal throughout the building. They ensure that the boosted signal is evenly spread, reaching areas that were previously plagued by weak reception. This uniform distribution is key to providing comprehensive coverage, ensuring that all parts of the building, from basement levels to upper floors, are able to enjoy the benefits of strong mobile signal strength.

  • Enhancing call and data transfer quality

    Signal boosters greatly reduce call noise and interference for businesses. Poor signal quality often leads to static, crackling, or other forms of noise during voice calls, making it difficult to understand the conversation and often leading to miscommunications. Boosters also enable faster data speeds, essential for various business operations like smoother video conferencing and faster file transfers.


There is always a solution to weak mobile signal within commercial venues across the UK no matter how rural the area is or how busy the network is with users and devices. Hopefully this article has helped explain how effective signal boosters can be as we’ve covered what they are, how they work, and how they can positively impact your organisation.
