How to Tell if Your Signal Booster is Working
So youâve got your signal booster all set up the green light is on and now you can make calls without fear of dropping them but how do you tell what your signal boosterâs actually doing how much is it boosting your signal if you get really terrible signal and now you can make a call then obviously itâs working but one if your phone just jumps up bar or two, itâs working properly right actually no did you realize that thereâs no standard for what a signal bar on your phone actually means take a look at this test, weâve got two phones sitting side-by-side receiving the exact same amount of signal on this phone it shows two bars but on this phone it shows four its a big difference even though theyâre getting the exact same amount of signal. signal strength is measured indBm or decibel milliwatts and it always shows up as a negative number the closer that number gets to 0 the better your signal strength. Youâll never actually reach 0 though the highest youâll see is about negative 40 which is pretty much perfect signal and five bars on your phone while a negative 120 is pretty much no signal at all or unusable signal and would show up is no bars or no signal. The best way to read this is to put your phone into test mode itâs really easy to do weâve got a video showing you how to do that right here so pput your phone into test mode and then do a test with your signal booster on and off youâll see how much your booster it is improving the signal keep in mind that phones sometimes will take a while to update so make sure you give your phone 30 seconds or so to make sure that your signal is updated. Ok, so youâve got your phone phone in test mode you flip the booster on and see your single jump from negative 115 to negative 85 thatâs an increase of 32 dB as pretty decent right? Well actually cell phone signal increases logarithmically so that thirty dB jump actually means your cell phone signal is a thousand times stronger if you had a 40 GB jump it be 10,000 times stronger so thatâs pretty massive improvement here a couple tips when testing your cell phone signal like I mentioned earlier your phone can sometimes take a while to update oftentimes your phone will only display one band when itâs actually receiving several for example it might only show the signal strength for your LTE up in the top of your phone when itâs actually receiving LTE and 3G signal so the booster might be boosting 3G signal dramatically but youâll never know because you canât see it on your phone to check whatâs really going on with your signal you can compare the bands on your phone on an Android device we recommend a great app called signal check light this will allow you to see signal levels for all the bands on your phone if you want to add a widget that youâll have to pick up the pro version itâs a great tool and in our opinion worth the price on an iPhone youâll need to compare the signal levels with and without a booster while LTE is turned on then go into settings and turn LTE off do the same test again with and without you booster now youâll be seeing as a signal reading for your 3G signal with this knowledge under your belt go out and do some tests and see the signal strength and how much is being boosted if you got any questions feel free to give us a call or leave us a comment will be happy to help you out and please subscribe to our channel we have tips like this coming out every week thanks for watching weâll see you next time
