Today, a reliable connection inside buildings is crucial, both at home and in the office. However, many of us are still finding it difficult to maintain a strong indoor mobile signal… Let’s find out what the challenges are in improving the mobile signal inside buildings, and what solutions can remedy the problem.
The challenges of mobile signals inside premises
Modern buildings are often constructed using reinforced concrete, metal and low-emissivity glass. Although excellent for energy insulation, they block radio signals…
In certain areas of the building, mobile phone users are therefore subject to dropped calls, reduced download speeds and reduced quality of service.
What’s more, the growing density of skyscrapers and other large metal structures only exacerbates the problem. They can create masking effects and signal reflections that disrupt connectivity. In these environments, signals can be weakened and, above all, unstable. They frequently fluctuate due to network congestion or weather conditions.
Technologies to improve mobile coverage indoors
Faced with these challenges, several technologies have been developed to improve mobile signal reception indoors. One of the most effective is the use of distributed antenna systems (DAS).
This is a network of small antennas placed throughout the building, connected to a common source that manages the signal. This system acts as a relay between the mobile phone and the operator’s tower.
Second solution: use a signal amplifier, or repeater. It picks up the external mobile signal via an antenna. This same signal is then amplified and redistributed indoors via one or more internal antennas. This process is ideal for areas where the outdoor signal is acceptable, but the structure of the building prevents efficient indoor propagation.
In very poorly served areas, where even outdoor signals are weak, femtocells are the best option. This small transceiver will create a local cellular network using your broadband Internet connection. Mobile calls and data from nearby users will be transmitted via the femtocell to the mobile operator via the Internet. You improve indoor coverage without depending on the signal outside.
Frequently asked questions
Is it legal to use a signal amplifier?
In most jurisdictions, the use of these devices is regulated. You must obtain approval from your mobile operator and, in some cases, a specific licence. This is to avoid interference with other communications and to ensure that use of the device does not degrade the network.
Can I install these solutions myself?
Femtocells are Plug & Play, so they require little or no configuration on your part. However, for DAS systems and repeaters, we recommend that you call in professionals. This will ensure that the system works efficiently without interfering with the outside network.
Towards a connected future
As mobile technologies continue to advance and user needs evolve, it’s clear that demand for reliable indoor mobile coverage will only increase. Innovations in DAS technologies, signal repeaters and femtocells, coupled with careful regulation, will play a crucial role in meeting this demand.
