How Does a Signal Booster Improve the Signal of Your 4G Antenna Signal?

For the longest time now, the use of signal boosters in the country has been greatly limited. The only ones who enjoyed benefiting from them are the operators themselves, from Optus, Vodafone, and Telstra. 


But there is a good reason behind it as misuse and abuse could pave the way for significant issues to occur on the network. If this happens, it could create an adverse impact on the mobile phone experience of various users that are nearby. 

Compared to their legacy predecessors, the new generation of 4G antenna signal boosters we have today is far more sophisticated than ever before. Hence, Optus, Telstra, and Vodafone gave their seal of approval for a limited array of products that are made accessible to the general public. This is even though engineering and proper deployment still play a major role in having a successful outcome. 

Nonetheless, there still exists a handful of shady 4G boosters but they’re in the underground market as they are being sold to everyone via the Internet. The vast majority of which are actually very hard to configure, if not highly effective. 

These shoddy types of boosters can disrupt the neighboring network, but above all, they are highly illegal. Take caution when dealing with cheap signal boosters that are usually found online in generic stores. They rarely work, but the harder part is you are likely to receive a serious fine.  

The Anatomy of 4G Antenna Signal Booster

Signal boosters work by collecting low outdoor 4G signals first. They are eventually amplified only to be redistributed to nearby indoor serving antennas. By this measure, 4G coverage can be further enhanced and thus mobile phone performance inside a building is also improved.

The exact implementation will vary and the location of the nearest mobile sites has something to do with it. The same is true also with the required mobile carrier service as well as existing cable pathways inside the building.  

Most of the time, the donor antenna would be situated on the building facade or sometimes they are installed even at a high altitude like the roof system. Ideally, there has to be a clear line of sight to a nearby macro tower of the relevant mobile carrier. Like for instance, this could be the macro site for Telstra

Maximizing the potential benefits of the rooftop antenna necessitates the use of specialized RF equipment to identify optimum advantage. Donor 4G antennas are usually directional antennas that are taken advantage of to enhance the donor signal strength. Besides, it also facilitates proper tuning, making noise out of the picture, which further enhances the quality of the signal received. 

When it comes to proper positioning, a 4G antenna signal booster equipment should be used indoors, so that it can stay protected against outdoor elements such as the wind and the rain. It also needs to have ready access to AC electrical power. For this reason, therefore, you must use and keep it inside the confines of your home or building. 

Some boosters can be grouped and cover larger areas like buildings and other structures of comparable scale. They amplify the signal although this would be highly dependent on the scope of isolation created between the serving 4G antenna and the donor.  

Isolation is defined as the effective ‘signal loss’, which usually occurs between the serving antenna and the donor. This will help in rendering the input to the booster not to “hear” the booster output. Otherwise, it will run the risk of the occurrence of ‘feedback’ or oscillation. 

When it comes to deploying signal boosters, one of the top-ranking mistakes by which many are guilty of is the failure to produce enough isolation between the 4G antennas. Consequently, this will stall any significant improvement in the wireless signal service.
