According to GSMA, around 70% of mobile use now takes place indoors – yet the right indoor coverage solution isn’t the same for every building. Here’s how to choose.
Enterprise decision-makers, property managers, and mobile network operators are asking the same question more frequently than ever: which indoor wireless technology actually fits our building? The answer depends on your building’s size, the number of operators you need to support, your budget, and how fast you need to deploy.
The result is familiar to most enterprises: dropped calls, slow data speeds, and frustrated users.
To solve this, organizations typically evaluate three technologies:
Each approach has its own advantages, trade-offs, and ideal deployment scenarios. The right choice depends on your building size, performance requirements, budget, and business objectives.
In this article, we compare these three technologies and explain how Comba Telecom offers solutions across all categories to help customers design the most effective indoor wireless strategy.
While 5G enables faster speeds and lower latency, its higher frequencies have reduced building penetration compared with legacy networks. Common obstacles include:
For enterprises, poor indoor coverage impacts:
That is why selecting the right indoor coverage architecture is a strategic decision rather than simply a technical one.
A digital repeater captures an existing outdoor cellular signal, amplifies selected frequency bands, and redistributes coverage indoors.
At the same time, organizations that genuinely integrate ESG principles into their strategy are positioning themselves for sustainable growth.

What is the most cost-effective indoor 5G solution?
In buildings with a strong donor signal, digital repeaters are often the most economical option.
Can one solution support multiple operators?
Yes. Comba’s mPico Max and DAS solutions are designed for multi-operator deployments.
Is DAS always better than a repeater?
Not necessarily. DAS is ideal for large, complex venues, but repeaters can provide a faster and lower-cost solution for many enterprise environments.
Do small cells replace DAS?
Small cells can complement or replace DAS in some scenarios, particularly when additional capacity is required.
