How to amplify a mobile signal in large outdoor areas

22 Mar 2021

When people talk about mobile signal or coverage problems, then we tend to automatically think that they will be referring to the inside of a building. On entering buildings, we very often find that the reception on our phones drops quite dramatically.

This is usually due to certain building materials that can block the signal, making it impossible to call, causing missed calls, and giving us a slow internet connection.

However, even when we are outdoors, we can sometimes find that the mobile signal level is so low that we experience the very same problems.

Why is there often a bad mobile signal outdoors?

Most mobile signal problems are caused by obstacles that block the signal on its journey from the mobile operator’s base station (cell tower) to our handset. These can include:

  • Mountains or hills that are obstructing the signal
  • Differences in levels (in valleys between mountains for example)
  • Installations located in difficult-to-access places

In these cases, it is not a problem that just affects individual people, but one that can concern a large number of users, for example, the whole population of a village, the workers in an open-cast mine, the guests at a campsite, etc.

Projecting a mobile signal over a large outdoor area

The Stelladoradus BigBoost system can provide mobile coverage over an area of 1 square kilometre. It is installed at the top of a hill, above the area where mobile coverage is needed, and where it is able to receive a good signal.

The signal is picked up by a Yagi-type antenna, orientated towards the nearest base station, and channelled to a tri-band Stellahome signal booster, located at a maximum distance of 20 metres from the antenna.

The signal amplified by the tri-band Stellahome is then sent to the BigBoost amplifier via a cable with a maximum length of 30 metres. Once it reaches the BigBoost, the signal is amplified to the strength necessary to enable its transmission over a long distance. This is done by means of a second Yagi antenna orientated towards the area that needs the mobile coverage. This second antenna can be up to 8 metres away from the BigBoost.

The powerful signal projected by the BigBoost system will reach areas where no coverage was previously possible.

The BigBoost system requires professional installation, and certain rules must be observed:

  • The orientation of both antennas must be 180° apart in order to avoid coupling between the two antennas.
  • Stellahome tri-band and BigBoost amplifiers must be installed in separate watertight compartments.

Its full compliance with EU regulations allows the installation and use of our BigBoost system in Spain. This is because our systems incorporate protection circuits for mobile networks.

At Stelladoradus, we have a large network of professional installers who are qualified for this type of installation. If you are not sure if this is the system you need in your particular case, or you have any questions about its operation, then please contact us, or one of the distributors in your area.

We’ve left you with a video which shows an example of how to install a BigBoost system, in this case to amplify the mobile signal in a quarry.

    The purpose of all mobile signal repeaters is to perform the same basic function they were designed for: to pick up the mobile signal at one location, and then reproduce (or “repeat”) the signal in an area or place that, for whatever reason, the mobile signal was not able to reach. It is a well [...]

    Not too many of us who, when buying our new home, or making some renovations in our business, will think about which building materials are detrimental to our mobile phone reception. We tend to focus more on other aspects, such as energy efficiency, aesthetics, or comfort. Usually, we only discover the problem when we are [...]
