How Cell Phone Signal Strength Is Really Measured
The number of bars on your phone is really subjective.
It’s not really tied to any standard. It’s up to your carriers to decide how much is 1, 2, 3, 4 or full bars on their service.
So what’s 1 bar on Verizon might be 2 on AT& T, 3 on Sprint or full bars on T-Mobile despite receiving the exact same signal and performing at the exact same speeds.
But luckily, there’s a way to find out your true signal strength. It’s called This is measured in decibel-milliwatts, or dBm.
Cell phone signal operates with a certain frequency:
-50 dBm to -120 dBm.
-50 dBm is full bars. -120 dBm is basically a dead zone. The closer you are to – 50 dBm, the better your signal.
So what does this have to with building material?
Well, building materials basically subtract dB from your signal when trying to enter your home. The more it subtracts, the closer you get to -120 dBm which is a dead zone.
Let’s look at which materials obstruct 3G & 4G LTE signals.
What Color Metal Roof Is The Most Energy Efficient
Energy Efficiency Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. It is best to choose a light color metal such as white, light bronze, beige, peach, light green or blue, if you live in a region that has a lot of sun and a hotter climate.
Do Metal Roofs Cause Bad Cell Reception
Many people ask if a metal roof could be the cause of their poor cell phone reception at home. Well, the short answer is no, it isnt!

All these locations often have metal roofs and you see no effect why should a metal roof on your home be any different?

Does A Metal Roof Affect Your Wi
Fast internet is a modern-day essential and most of us want to avoid anything that is going to interfere with our reception. People often question whether a metal roof can interfere with their wi-fi, so were here to put rumours to rest. Whether youre experiencing slow internet and wonder if your roof is to blame or youre considering a new roof we answer the common question does a metal roof affect your wi-fi?
Good news: your metal roof will not affect wi-fi
The idea that a metal roof will make your wi-fi worse probably came from the fact that metal objects can interfere with communication signals. Its usually because they are dense objects in close proximity to the signal sender. Your metal roof is not likely to be dense enough or close enough to your wi-fi router to create a problem.
What can affect your wi-fi?
There are lots of simple reasons your wi-fi connection might be slow. Heres three common reasons for slow internet, none of which are your metal roof:
Your device is too far from the router
A wi-fi router sends out a connection signal to a certain distance. The further away you are from the signal centre, the slower your internet may be. Outside of this distance you wont have any connection at all. If youre far away from your wi-fi router you may be outside its connection distance. Your metal roof will not change the maximum distance for your wi-fi router.
You have too many devices connected
Big objects inside your home
The Right Wireless Router

In most cases, purchasing the router with the longest possible range will help you keep your internet signal intact. Find the most powerful router available at your local electronics store, or look online. If this does not solve the problem, speak with your Internet service provider about the best hardware for your home.
You might also want to purchase a wireless repeater. This strengthens the overall Internet signal throughout your house. Even long range routers can benefit from the repeaters. The repeaters will extend the range of your router.

How Can I Boost My Cell Phone Signal With A Metal Roof
If you have a metal roof and have noticed problems with your cell service, you may need to consider creative solutions. One way to boost your service is to install a repeater system, or signal booster. It includes an antenna placed outside, a signal amplifier and an inside antenna. A cable connects all of the parts.
The outside antenna picks up the cell tower’s signal and sends it to the amplifier, which boosts the signal. Then the second antenna broadcasts that signal to the surrounding area, giving you a strong connection your phone can pick up. If you have a usable signal within range, the repeater should fix your problem quickly.
Should A Metal Roof Be Grounded
The short answer is no, a metal roof does not need to be grounded. In most cases, you will not incur additional risk if you dont ground it. Metal does conduct electricity. But when dealing with a full roof, a lightning strike would ground out through the structure, causing no more harm than non-metal roofs would.

However, if you are able to get spotty reception inside, a wireless card should help. For smartphone users, youre SOL unless you tether to the laptop.

What Is A Wireless Dog Fence
Well, it surely isnt just the opposite of a wired fence, thats a given. In fact, a wireless fence isnt really a fence, it just acts as one. A wireless fence is a radio device that you simply plug into an outlet in your house. From there it emits a simple radio signal in a radius around itself and around the house.
The range of that radius depends on the device, as well as on how you set it up. Generally, it can vary from 10 feet to 150 feet. At maximum, a wireless fence can cover multiple acres!
This radio signal can be detected by a device thats put into your dogs collar or rather, in your dogs new collar that you get when you purchase a wireless dog fence system. And, whenever your dog gets close to the circular perimeter formed by the radio emissions, the collar gives out a sound warning that aims to stop Fido in his tracks.
Should your dog ignore the sound after several more feet, the collar emits a mild electric stimulation thats usually referred to as a static correction. It’s nothing painful or hurtful, just enough of a stimulation in order to surprise your dog and stop him in his tracks.
A wireless dog fence is quite similar in its purpose to a standard, training shock collar.

These systems can boost the signal indoors for one or several cell phones. They will also improve the cell signal to a hotspot or cellular router to improve your data speeds.
The right system for metal buildings will depend on a few factors. Factors like the signal strength outdoors and the size of the area you want to cover indoors.

Disadvantages Of Metal Roofs
Despite their many advantages, metal roofs have some potential drawbacks.
- Affordability. Metal roofs can be as much as two or three times more expensive than other roofing materials. While the life of a metal roof is much longer, investing in a metal roof only makes sense if you plan to stay in your home long enough to enjoy the cost benefits.
- Noisiness. Metal roofs may be more noisy during a heavy rain or hailstorm than other products depending on the type of decking used during installation . Adding more attic insulation can sometimes solve this problem, but that may increase costs.
- Expansion, contraction and fasteners. Metal roofing material assemblies that are attached as large panels are designed to expand and contract as they warm and cool. However, both exposed and concealed fasteners have varying lifespans. Depending on the climate, neoprene washers and the screws used during installation may degrade and become dislodged over time.
- Inconsistency of color match. If a repair is required or a home extension is added years later, it may be difficult to find an exact match to the existing metal.
- Performance. If water accumulates anywhere on the roof because of poor-quality installation or repair, it can eventually cause serious damage. Low-grade metals may also be thinner gauge and less durable. Some metals rust in certain climates or dent more easily than others during hailstorms or installation.
Physical Obstacles To The Wi
With shorter range, equipment on the 5 GHz band is more dependent on the having a clear line of sight between the wireless access point/router and the clients devices and computers connecting to the network.
Some obstacles are simple to remove, and in some cases you may be able to move the access point away from the obstacles. Building materials in the home are harder to address, however. The solution we recommend to ensure coverage in such cases is a mesh network of several wireless access points that can work their way around the obstacles.

Why Does Metal Interfere With Wifi
Tall buildings have metal frames, which causes problems for wireless reception. Wireless signals affect radio waves. Unfortunately, metal is a conductor of electricity and magnetism, and so it absorbs radio waves. The more metal a building has in its structure, the worse the radio reception is for the people inside.
