In most scenarios, the closer you are to an actual cell tower, the closer to -50 dBm your phone will be. *-100 to -80 = you have a signal, but it’s weak To get a little more detail, check this out: Any frequency lower than -50 and higher than -120 is not compatible with modern cell phone technology. So -50 dBm is full bars and -120 dBm is the no signal threshold. The lower the dBm number, the better your reception is. 50 dBm to -120 dBm is the frequency that your cell phone operates in. It’s difficult to tamper and interfere with it. This is an even more accurate logarithmic unit than dB. The downside is that radio waves are easily disturbed with interference.Ĭell signal strength, on the other hand, is measured in decibel-milliwatts, abbreviated as dBm. AM and FM radio waves have been using decibel measurements for over a hundred years. Decibels is a very reliable unit of measurement. For mobile signals, the abbreviation is dB. What Do Decibels Mean To Cell Signal Strength?ĭecibels are a logarithmic unit and it’s what mobile signals are measured in. This is the first step toward discovering how to fix your bad signal strength situation. How do you know for sure how to interpret your phone’s signal bars? You need to know the exact number of decibelsyou’re getting. You’ve probably had an experience where it said you had 2 bars of service, but calls still weren’t coming through. But how good or bad it really is can be hard to determine. It’s true that, in general, more bars means better signal. What we’re saying is that there is no standard in this area. Different models, particularly ones that are made solely for use with a particular provider, can have their own way of displaying reception levels on-screen. The model of your phone adds even more differences to the mix. They all use their own cell towers with a system that’s unique to them. These examples may not be precisely accurate, but the point is that the system is not the same between carriers. Or 3 bars with Sprint could mean 2 bars with Verizon. For example, full bars on T-Mobile could mean 1 bar with AT&T. That’s because all of The Big 4 - Verizon, AT&T, T-Mobile, & Sprint - have a different on-screen reception system. They’re supposed to tell you what kind of reception you’re getting at any given moment. The truth is that these little mobile reception bars are not very helpful. (Those ascending bars on the top left or right of your phone’s screen). With that out of the way, let’s spend a quick moment talking about cell phone bars. Maybe one day it will but for now, the best solution is a cell phone signal booster. The popular saying there’s an app for that doesn’t yet apply to cell signal boosting. But as of right now, that technology isn’t available. We wanted to get this information out of the way first. Are There Any Apps That Boost Cell Reception? We’ll also talk about ways you can use your smartphone (using no app) to get detailed info about your signal strength.īut let’s start by addressing the question that’s probably on your mind right now: 1. These apps are very helpful, particularly if you live in an area with notoriously poor cell reception. Some of them even tell you where the nearest cell tower is. There are many cell signal strength apps available that help you do just that. Wish you had a convenient way to find out exactly how good or bad your cell reception really is? No need to worry.
