Why don’t we get mobile signals in few areas of our home ??

Concrete can’t block Mobile signals as mobile signals are Radio waves and can penetrate through walls of our home. Then why there would be no signal in few areas like interior rooms or basement etc?

It happens to everyone. You’re on a get and the association drops out. On the other hand possibly you’re utilizing a GPS application to locate a new address, and it abruptly stops working on the grounds that the signal has vanished. Presently what do you do? Drive around with expectations of grabbing the signal once more? But, It’s probably not your carrier’s fault. When things like this happen we all love to blame our cell service providers for the poor coverage. The truth is, most of the time it’s not their fault. The culprit is typically something between us and the cell tower that blocks the signal so we can’t get good reception.

Radio waves are a sort of electromagnetic radiation that is exceptionally helpful for communication purposes however not hurtful at all. Radio waves are ordinarily waves with low frequency and long wavelength. These waves are useful for traveling long separations yet are not very powerful. This allows simple metals to block radio waves. Most metallic objects, like aluminum foil, iron or zinc objects, anything with copper or iron oxide paint, steel pots, and iron skillets can block radio waves. However, depending on the frequency of different radio wavelengths, some wavelengths may be powerful enough to surpass certain metals. Unfortunately, every home is built using these kind of metals apart from concrete. Residential building materials include steel, aluminum, stainless steel, copper, zinc and alloys of several metals. So, if signal gets blocked in any part of your home then technically your home must bear the blame.

Even, Hills, mountains, ridges, bluffs and similar terrain will block cell signals. Any case in which there is hill between your phone and the cell tower can cause signal issues. If you have driven through hilly area you know that you might have a good signal one moment, and then when you go around a corner or into a low spot the signal may vanish only to reappear a short time later. That’s the terrain messing with your cell signal. A nearby bridge, utility tower, highway overpass or almost anything else built by humans can interfere with cell phone connectivity. RF signals can’t easily pass through metal or concrete, so anything built with either or both can cause reception problems. In urban areas, structures can be the main culprit that blocks cell signals. Large buildings, like any natural or man-made obstruction, can deflect or distort RF waves. Driving into a parking garage is a virtually foolproof way to drop a cellular connection. We’ve already mentioned about metal, but almost any materials used in construction – shingles, masonry, wood, drywall, even glass (especially the metal-oxide-coated low emittance type) – will weaken or block signals as they attempt to pass through. So when you’re at home, in the workplace or inside almost any building you can encounter cell phone signal problems. Most of us have experienced a poor cell phone connection while inside a vehicle, and then noticed a marked improvement in voice quality or data transfer speed once we step outside. Those metal-and-glass encased cocoons we drive do an excellent job of blocking cell phone signals. It may seem hard to believe, trees, shrubbery, almost any kind of foliage can absorb cell signals. Here’s the kicker – even dust particles in the air can weaken RF signals. A foggy day? Water vapor can diffuse RF signals.

Some blocks can be removed by simply opening a window or door but for some blocks we must change our location.


Thank You.
