The Challenge: Why Indoor 4G Signals Struggle
When designing a building, architects and engineers often prioritise comfort, convenience, and durability over mobile signal strength—and that’s understandable. So, while materials like concrete, steel, and tinted glass are highly sought after for their structural integrity and aesthetic appeal, they often pose challenges for mobile signal transmission. For instance, robust concrete walls can absorb and block radio waves, significantly diminishing mobile reception indoors.
The building layout matters, too. Buildings with multiple floors create obstacles, as signals may struggle to travel vertically due to the density of materials used in floors and ceilings. Other environmental factors include the proximity to dense foliage or nearby tall buildings. Trees can obstruct signals, and adjacent high-rises can cause interference, creating a shadowing effect that diminishes the strength of mobile signals reaching your office building, expansive warehouse or apartment complex.
Let’s not forget about your building’s distance from mobile towers. As the distance increases, signals become weaker, leading to the likelihood of dropped calls, slow data speeds, and other frustrating delays and missed business opportunities.
Our Solution: Smart Technology for Strong, Consistent Indoor 4G
Com2 Communications employs a range of cutting-edge technologies to amplify and distribute 4G signals effectively indoors. Here are multiple ways we do it:
4G Indoor Signal Booster
If there’s a decent 4G signal just outside your office building or residential complex, a signal booster is often a cost-effective solution. All we have to do is install an external antenna to capture this signal, a powerful amplifier to boost its strength, and internal antennas to distribute the boosted signal throughout your desired areas. The result? Improved call quality, faster data speeds, and happy staff, customers & residents.


Distributed Antenna Systems (DAS)
Do you own a large, expansive or complex building? Consider a DAS for 4G. With a good Distributed Antenna Systems architecture, your building can have a network of strategically placed antennas connected to a central source. What does this system do? It essentially captures the outdoor signal (or directly connects to the mobile network) and distributes it evenly across vast areas and multiple levels. That makes it suitable for large offices, shopping centres, hotels and other multi-storey buildings, especially those with challenging dead spots like basements & multi-level car parks.
Small Cell Solutions
Consider small cell solutions for areas with extremely weak or no outdoor signal or where there’s a high demand for mobile data. Small cells connect directly to the mobile network and provide dedicated 4G capacity for your premises. That also makes the small cell technology ideal for high-density user environments or businesses requiring premium performance & capacity for their staff, clients & guests.
