RECEIVING BAD SIGNALS IN YOUR OFFICE? HERE’S WHAT YOU NEED TO DO.

 

One of the main problems in newly built offices is that the phone and 4G signal is not good. The outdoor mobile signal can hardly pass through concrete, stone or thick walls, causing phone calls to stutter or drop. Sometimes it is not possible to call at all, but when we put ourselves close to the windows the signal is available and allows us to call. This problem is expected to only increase with the arrival of the new 5G network.

How come there is no mobile coverage in the newly built offices?

There are plenty of examples of newly built office buildings with excellent mobile signal outside as there are more than enough transmission masts but yet we find that the mobile signal inside is poor often low to moderate. There are two main reasons for this problem...

 

1. Too much insulation

The first and most well-known cause of weak or no signal is too much insulation in new buildings. The insulation of new buildings is more and more efficient these days. Not only have the regulations become stricter, but the standards are also higher. Good insulation keeps more heat inside the building, which leads to lower energy costs.

Today's double-glazed windows are often constructed in three layers to reduce thermal bridging and increase insulation value. The thicker the window, the less signal enters. We often find that a reasonable phone call can be made to a window. Sometimes it is even possible to make a call when the windows are open. If the windows are closed, the signal is too weak and calls will be missed or dropped.

Not only is this very annoying (companies can miss orders), but it can also be very dangerous. If 112 has to be called and there is no mobile signal, this can of course has significant consequences. Of course, landlines can still be used, but the trend shows that this is being used less and less.

 

 

1. The height of the building

Not only does the isolation cause a weak mobile signal, but the height of the desk (or rather the transmitter mast) also causes a weak signal.

This problem often arises in metropolitan areas. Transmission tower transmitters are often found on rooftops or in special transmission towers. When transmitters are on masts, they often reach no more than 15 meters. When transmitters are on rooftops, frequencies have difficulty reaching all floors.

Often the signal in an office building is good on the lower floors. The higher you go, the weaker the signal. A transmitter on a tower is placed so that it broadcasts the signal horizontally into the environment. The signal does not reach the upper floors of large office buildings, so the signal on the upper floors is often weak.

 

1. How can I boost mobile coverage?

What many people don't know is that the moving span inside a building is reasonably easy to reinforce. By using a GSM repeater (also known as a GSM booster), the signal can be brought from outside to inside the building. A GSM repeater works with an external and internal antenna. The outdoor antenna is placed outside, preferably as high as possible. The outdoor antenna receives the signal from outside, the signal is received from the transmitter mast. Through a coaxial cable, the signal is routed to the repeater, which is connected internally. One or more indoor antennas provide the signal inside the building. Only the repeater is connected using an adapter, the antennas are connected using a coaxial cable to the repeater. A standard repeater set comes with all the essentials. The more powerful the repeater, the more indoor antennas can be connected to the repeater.

A GSM repeater receives one or more frequencies. It is therefore possible to use a single repeater to reinforce several telecommunications providers.

 

1. What should I pay attention to when installing a GSM repeater?

In principle, installing a GSM repeater is quite simple, but there are several important points to consider.

1. Make sure the outdoor antenna is installed outdoors

This seems very obvious, but we find that it often doesn't go well. When the outdoor antenna is placed indoors, it will receive virtually no signal. There is no signal inside. However, the outdoor antenna is often placed indoors, due to the limited technical possibilities or from an aesthetic point of view.

2. Do not place the indoor antenna too close to a window.

When an indoor antenna is placed near a window, the repeater may receive the signal from that indoor antenna. Especially when the outdoor antenna is also placed near the same window. When the outdoor antenna receives the signal from the indoor antenna, interference occurs, and the repeater amplifies its signal. The repeater, therefore, amplifies its signal and will turn off automatically for safety.

Make sure that there is enough ground (eg walls) between the outdoor and indoor antennae so that the antennas cannot receive each other's signal.

3. Do not use products other than those provided

It is advisable to use only the products provided or at least the products listed on our website. Often other coaxial cables are used, for example, 75 Ohm (resistance) coaxial cables. These are coaxial cables that are used for television and alarm systems. These cables have different damping, so they do not work in combination with a GSM repeater. For a GSM repeater, you need coaxial cables with 50 Ohms, which are characterized by their low signal loss. The use of other connectors or indoor and outdoor antennas is also not recommended, as they often do not support the correct frequencies

4. Seek advice in advance from GSM REPEATER SHOP

Not sure which repeater and accessories you need? Then contact us for personalized advice. Based on the address, we can see where the relay antennas are located and determine the most suitable outdoor antenna. Then, with the building plans, we can determine how many indoor antennas will be needed and where they should be placed for optimal operation. With all this information we formulate advice so that you know what you need and how to mount it. Of course, without any obligation!
