It has happened to all of us that we do not have enough telephone network and that our telephone displays "network unavailable" which means that we cannot reach anyone and that people cannot reach us either. The message "phone network unavailable" or "no service" gives us the impression that we do not have a phone with us. We are no longer connected to the world, but why don't you have a telephone network? This can be due to several reasons. The three main reasons are the distance from the BTS, obstacles between you and the cell tower, and the isolation of the building you are in.
- 1. Distance from the BTS
- 2. Obstacles between you and the cell tower
- 3. Insulation material
- 4. Solution
1. Distance from the BTS
The most logical explanation for the fact that you do not have a telephone network is that you are too far from the cell tower. The further away you are from the cell tower, the weaker the signal.
Unfortunately for users, a weak signal is still a signal, while you cannot even call or surf the internet. The provider may offer this signal in an area that it deems little or no need to better cover. You can use the Finnsenderen site or Mastedatabasen to see where the relay antenna is located.
2. Obstacles between you and the cell tower
The second common cause of the lack of an unavailable telephone network is due to obstacles. These obstacles stand between you and the base station and come in different sizes and shapes. For example, an obstacle can be a hill, trees, or a building. These obstacles make you have a bad mobile network unavailable only one bar.
This is because the signal generally cannot cross these large obstacles. The signal is then returned in the direction from which it originated. The signal does not reach you because it propagates best when there are no obstacles between you and the cell tower. As soon as you are no longer "in sight" of the mast, signal reception becomes much less reliable.
3. Insulation material
The last common cause concerns the insulation of the building you are in. Building materials such as stone, concrete, steel, and wire mesh are known and obvious blocking factors for moving signals. In addition, certain items such as energy-saving window coverings, tiled roofs and / or metal roofs prevent you from having a satisfactory telephone network.
If you notice that you have good mobile range outside the building, but it decreases significantly as soon as you enter the building, it is very likely that the mobile network unavailable issues are due to construction materials.
Now that we know why you can have a weak or nonexistent phone network, here are the solutions. Unfortunately, we cannot change the power or number of cell towers and the insulation in your building.
Also, you don't have a mobile network for many of these reasons, but to find a solution, it's good to know clearly what causes you not to have a mobile network.
Once you've determined why you don't have a phone network, we can begin to determine which repeater you need.
If you do not have an available mobile network and this is mainly due to the distance between you and the base station and obstacles, you can choose a very powerful outdoor antenna, regardless of the frequencies and the power of the repeater. You are less than 5 km from the relay antenna, we advise you to choose a directional antenna Yagi Logarithm . If the relay antenna is between 5 and 14 km away, we recommend that you choose a directional antenna Super Yagi Logarithm . Suppose that is not enough, then we have a satellite dish for a number of frequencies.
If, on the other hand, you live in the city and the fact of not having an unavailable mobile network is due to the insulation of the building, you have enough with a panel antenna or a marine antenna . The panel antenna will be received at 180 ° and is suitable for short distances up to 1 km, the marine antenna is omnidirectional so it will receive the signal at 360 °.
