Connect with us

The Distributed Antenna System (DAS) is one of QMC's solutions for indoor environments that offers high-quality coverage for your enterprise. DAS provides signal via small antennas strategically located in your venue that connect you to the carriers’ mobile networks. Unlike Wi-Fi, DAS gives you guaranteed connectivity, wherever you need it.

It doesn’t matter if your business is a corporate building, a hospital, a university, a hotel, a convention center, a stadium or just a single floor in a building. We are ready to serve you with a turn-key indoor solution, tailored to your needs. Once the solution is installed, we manage it for you and handle all of the external parties—you don’t have to lift a finger.

Active DAS

ACTIVE DAS is best suited for large venues that serve a high volume of people, where providing network capacity is the venue’s most important requirement. Examples of such places are shopping malls, hotels, stadiums, hospitals, airports, university campuses or convention centers.




ACTIVE DAS uses amplifiers (remote units) connected to a point of interface (which gathers all the signals from the operators) through fiber optic cables and are positioned close to the transmission antennas, which are spread over the building that needs coverage and capacity. With an ACTIVE DAS the signal arrives with superior quality and strength to the amplifiers, which improve the signal provided by the wireless antennas. In addition, it is an easily adaptable infrastructure for new technologies such as 5G technology and can be designed and implemented in projects of any size.

Passive DAS

A system suitable for smaller venues and lower volumes of people. Passive DAS presents lower implementation costs when compared to an active system, but it’s not adaptable for new technologies (5G), changes in layout, or addition of new areas in the venue project. Lastly, it does not allow remote network monitoring.




The PASSIVE DAS uses passive components, such as coaxial cables, splitters and diplexers, to distribute the signal through the low power antennas directly connected to the operators' radio equipment. It does not convert the RF signal to optical signal as an ACTIVE DAS does.

In today’s economic climate, cost management is a central issue for any company. In telecom, a key driver of efficiency is that a mobile operator’s asset can provide capacity for more than a single location / enterprise. Within this context of enhancing capital and engineering efficiency, it is possible to achieve greater synergies between network elements and areas with coverage needs.

The Centralization Solution, or C-Solution, arose through this philosophy. From one central baseband transceiver station in an equipment room, operator cellular coverage can expand with little to no extra cost to areas that don’t have good cell service.

QMC’s C-DAS solution uses the idle capacity of a pre-existing infrastructure nearby and generates savings by eliminating CAPEX costs and reducing ongoing OPEX. C-DAS provides the same quality of a QMC Active DAS combined with economies of scale provided by the C-Solution.

Lite DAS



What is LITE DAS?

While DAS is a solution to ensure connectivity throughout an enterprise - such as a building, a mall, or a hospital - LITE DAS is a customized version that covers only one or more floors. It is ideal for corporate offices, since it is a quick and easy installation solution. The implementation is immediate.




How does LITE DAS work?

The structure of LITE DAS is segmented into 3 elements: the Access Unit (AU), the Extension Unit (EU), and the Radio Unit (NPRU). Finally, these three elements are connected through passive components, such as jumpers and antennas.


What are the benefits of LITE DAS?

Low cost solution

No need to rent space in the common area of buildings

Quick deployment

Evolution and expansion facilitated

Possibility of equipment relocation
