Why cellphones stops working in some places?

Why cellphone stops working?

Do you know why your cellphones don't work in some places! 
Some of these places mainly crowded places where our phone stops working.
Here is the list of some places where our phone stops working. 

1.The open sea

 When you're traveling on a huge cruise ship that has its own satellite-based technology to let you stay on the grid, the open sea is mostly one massive coverage gap.

This is because of how the cellphone system works. Providers take care of certain assigned areas setting towers with multiple antennas to transmit signal. They all have a limited coverage radius.
And because they are all physically on land, that signal simply can’t reach your small yacht in the middle of the Atlantic. Enjoy the peace and quiet 

2.Pretty much any national park

Some countries have official laws banning cell phone tower construction within the parks' boundaries

So don’t expect to text and call from Hoh Rain-forest or Sequoia National Park, and share

stories from the Great Smokies or Joshua Tree National Park, to name a few. Elsewhere, the Department of Wildlife in Sri Lanka asked cell phone service providers to block coverage in Yala park during peak tourist hours.

They did it to protect the animals. And it’s not that the critters complained about getting too many robocalls…A lot of incidents happened when guides spotted, say, a leopard, called others, and too many cars
rushed to the spot.

3.The Mariana Trench

 If someday going down the deepest trench in the world becomes a common tourist activity, you won’t be able to live stream your adventures. First, the water itself doesn’t let the cell signal go through.

Second, if you’re inside a submarine (and that would be the way to go), it works like a cage that blocks radio frequencies and electromagnetic fields. Never mind the pressure.

4. Socotra

The island of Socotra in the Indian Ocean has unique alien-looking plants you won't find anywhere else but no resorts and practically no cell phone coverage. Well, they call it one of the most isolated places on Earth for a reason.

5.Green Bank, West Virginia

 This beautiful little town not so many people have ever heard of is located in the Radio Quiet Zone. Here, scientists are carefully listening to galaxies exploding somewhere in the universe

using the world’s largest radio telescope. These sounds are so vague, any electronics would interfere with the process. So, cell phones, Wi-Fi, and even household appliances like the microwave are off-limits

for both the locals and rare visitors. Do not interfere with us, earthling.

6.Digital detox resorts

      Some people willingly pay to spend time off the grid. Mobile phones and laptops are officially banned within a half-mile radius of white-sand beaches at multiple Caribbean resorts. One popular hotel in Bali banned photos, calls, texts, and social media by the pool from 9 am to 5 pm to let guests actually relax by it.

They did it after becoming one of the most Instagram-med locations with people only coming there for photography. That makes me wonder … Maybe concert and sports events organizers also want you to just focus on the show and so they somehow block the connection at mass events?

But that’s just a guess, I’ll get back to it later.

7.Pitcairn Islands

Only one of the four Pitcairn islands is inhabited by fewer than 60 people. They encourage others to join them by offering free land on this Pacific island. But even super low taxes, crystal clear water, and summer all year round don’t inspire too many people to jump in – maybe it’s lack of cell phone service that’s discouraging folks.

8. Tikaboo Valley

There is just one spot with some cell phone reception and one public phone in Tikaboo Valley in Nevada. There are no cell towers in this desert for two main reasons: there's a top-secret facility

nearby and it's super remote.

So if you ever decide to get as close to Area 51 as you possibly can, try to stay safe as you won’t be able to call for help during your hike.

9.At some restaurants

Some restaurants charge their clients a fine for using cell phones while eating. At a cafe located three hours northwest of Marseilles, France, phones are officially banned.

When you use it for the first time, you’ll get a yellow card from a waiter. The second attempt means a red card, and you’ll be asked to leave the restaurant.

Wow just like in soccer. And, they blow a whistle every time they see you break the rule so that everyone knows about it. They do it to inspire people to talk to each other and not their gadgets. Wow, if you keep it up, do the waiters do penalty kicks aimed at your table?

Sign up! What do you think, would you manage to finish dinner at a place like that, or would they give you a red card because you can’t live without your phone? Let me know in the comments below.

10.In a crowd

You arrive at your favorite band’s concert you’ve been waiting for for years. You take the best shot ever and … you can’t share it online. Your phone might have four or five bars, but nothing works out.

The same happens at sports events, festivals, and parades, and even on a busy road during rush hour. Is this some kind of conspiracy to prevent you from sharing your exclusive content or sounding off the way you feel about traffic jams?

In fact, it’s a technical issue. Too many phones trying to send and receive signals from nearby cell towers simply overload the network. Even just calling and texting is super hard at such times, and trying to do data-heavy things like sharing photos and videos only make things worse. There’s also a mix-up of signals when your phone is trying to get through and connected to the correct network.

Stadiums and concert halls know about this situation, of course.

 They are trying to solve the problem by installing extra small cell antennas to boost signals coming from larger usual ones.

Another idea is to use cell phones instead of towers to share signals. Wi-Fi systems also help to somehow unload the pressure on cellphone networks.

11.In hilly areas

Sometimes you can find yourself on the wrong side of the hill for phone reception. Even if there is a cell tower not far from your home it won't help you much if the signal

is blocked by a hill or a mountain. On the other hand, people living far away from a cell tower they can see from the other side can have a perfect connection.

This is due to the fact that radio waves travel in a straight line and don't like any obstructions. Well, I don’t like obstructions. Do you?

12.Anywhere in bad weather

 Have you ever noticed how bars drop during a thunderstorm? That happens because radio waves travel through the atmosphere, and when raindrops, dust particles, and ionized particles get in their way they mess up the signal.

In fact, even stuff going on in space influences cell reception. Shock waves from eruptions on the Sun can change the Earth’s magnetic field and send gas into the atmosphere.

Hey, I send gas into the…never mind. Anyway, all that doesn't exactly help your cell signal.

13.In a fast-moving vehicle

 It's understandable why you have no reception in a tunnel under layers of concrete, but sometimes it abandons you in a fast-moving car or train.

This is because when you're traveling at high speed, you change your location way too fast for radio signals to move between your cell phone and the right cell tower.
