3 Ways To Cure The Cell Phone Dead Zone At Home

Can you hear me?” “Can you hear me now?” If most of your cellphone conversations begin this way — or if you’ve taken to hanging out a window just to get a signal — you’re not alone.

Spotty cellphone service can be especially frustrating when you have full bars in your building’s lobby or hallway but one measly bar as soon as you set foot inside your home.

It turns out, there are good explanations for why this occurs (no, the cellphone gods aren’t trying to punish you for posting too many selfies) and solutions that renters can easily implement. Here’s how.




Cause #1: The position of your building’s cellphone antenna

Cell carriers in all major cities position their cell sites close to the ground because that’s where most of the people are,” says Graham Caparulo, principal consultant for Diligex, a New York, NY–based managed IT services provider.

On the corners of buildings, you’ll see them 20 to 30 feet up, and they’re angled toward the street.” That doesn’t do you much good, especially if you live on the 30th floor of a high-rise.

Cause #2: Building materials can block radio signals

Tinted windows (especially the ones found on “green buildings”), concrete, and metal all interfere with cellphone reception — which is why you can often get more bars if you hold your phone out your window or step onto a balcony.

Cause #3: You live in a densely populated area

Have you ever noticed that your service is slower at night or on weekends, or when you attend a packed basketball game? The more people using a network, the slower it runs.

Each cell tower only has limited radio channels it can use,” says Caparulo. “When it’s full, you’ll have bars but can’t make a call or use data.

Solution #1: Invest in a cellphone booster

Invest” is the right word here, because a cell signal booster will typically set you back between $400 and $1,000.

A traditional cell signal booster takes in a signal on one end, amplifies it, and spits it out on the other end,” says Caparulo, who cautions that you have to have a good signal to work with in the first place, which may mean putting the booster’s antenna outside your window — a no-no in some apartment buildings.

Solution #2: Enlist a femtocell

A femtocell, also called a microcell, basically uses your Internet connection to back up your cellphone,” says Caparulo.

The device plugs right into your modem or router and uses your Internet connection as a cell signal booster.

Solution #3: Enable Wi-Fi calling on your smartphone

This feature, available on the iPhone 6 series and many Android phones, allows your phone to use your in-home Wi-Fi connection to make calls. (On the iPhone 6, go to “Settings,” then “Phone,” and it should be the first option.)

Charging Your Phone While Moving Around? Be Amazed By This Wireless Gadget Charger!

Scientists at Stanford University in the US have developed a device that can wirelessly charge a moving object at close range.

The technology could one day be used to charge electric cars on the highway, or medical implants and cellphones as you walk nearby.

“In addition to advancing the wireless charging of vehicles and personal devices like cellphones, our new technology may untether robotics in manufacturing, which also are on the move,” said Professor Shanhui Fan.

According to the study, published in the journal Nature, wireless charging would address a major drawback of plug-in electric cars their limited driving range. A charge-as-you-drive system would overcome these limitations.

“We can rethink how to deliver electricity not only to our cars but to smaller devices on or in our bodies. For anything that could benefit from dynamic, wireless charging, this is potentially very important,” Fan said.

The team transmitted electricity wirelessly to a moving LED light bulb but the demonstration only involved a one milliwatt charge, far less than what electric cars require.

The scientists are now working on greatly increasing the amount of electricity that can be transferred, and tweaking the system to extend the transfer distance and improve efficiency.

According to the research, the transfer efficiency can be further enhanced if both coils are tuned to the same magnetic resonance frequency and are positioned at the correct angle, but scientists found that was a complex process.
