Short Answer
Mobile reception is primarily weakened by reinforced concrete, metal, coated glass, basements, elevators, machinery, topography, distance to the cell tower, and network load. Disturbances, poor signal quality, or unfavorable frequency bands can also pose problems. Consequently, a room with windows may have good reception, while a conference room or basement is practically unserved.
Mobile radio is radio technology. Anything that attenuates, reflects, or disrupts radio waves can degrade telephony and mobile data.
Building Materials
| Material | Effect |
|---|---|
| Reinforced Concrete | Very strong attenuation. |
| Metal Facades | Reflection and shielding. |
| Coated Windows | Significant reduction of external coverage. |
| Soil | Critical in basements and underground garages. |
| Elevators and Shafts | Local shading and radio dead zones. |
Environment and Network
- Hills, valleys, and neighboring buildings can cause shading.
- The distance to the mobile network tower affects signal strength.
- Many users on the same tower reduce data performance.
- Different providers use different locations and bands.
Signal Quality Instead of Just Bars
Poor mobile reception is not just due to a weak signal. Interferences and poor quality can also cause connection issues. Therefore, values such as RSRQ and SINR are important.
FAQ
What blocks mobile reception most strongly?
Often reinforced concrete, metal, coated glass, soil, and interior rooms.
Why is reception poor in the basement?
Soil and concrete strongly attenuate mobile radio signals.
Can weather interfere with mobile reception?
In normal mobile radio, usually less than buildings, terrain, cell load, and network situation.
Why do providers have different quality?
They use different locations, frequencies, capacities, and network planning.
