Affects signal quality. As you move locations, the app continuously updates. You don't have to tap a button to get your dBm reading. 3. Signal Strength Available on Google Play Store Signal Strength is a super basic WiFi and cell phone signal strength app. Upon opening the app, it will start detecting your signal strength real time. Make sure the 4G or 5G cellular tab is selected. By default, the app rates your signal from low to good and measures it in ASU. For dBm, tap the dB icon on the top left corner.4. LTE DiscoveryAvailable on some Google Play StoreThis app analyzes LTE, 4G, and 5G signals. While it may not boast the best layout, it's pretty straightforward. Signal strength is automatically calculated on the top left corner. Like the Network Cell Info Lite app, it automatically updates after a few seconds as you move around. Lower on the screen, it also identifies the direction of the cell tower you're connected to.5. Open SignalAvailable on Google Play and the App StoreOpenSignal doesn't provide dBm readings. Though, it's still worth mentioning, especially for iPhone users as it's more difficult to test signal strength on iPhones.If unable to get your dBm readings through an app or field test mode, OpenSignal is a great resource. It allows you to test your WiFi and 4G/5G data speeds. Areas that yield a higher speed have a stronger signal.It also features cell coverage heat maps to assess the quality of coverage from any carrier in your area. Data is crowdsourced, ensuring the most precise and reliable results.Field Test Mode - Get Reliable Signal Readings Without an AppUnfortunately, there aren't many apps to measure cell signal strength on iPhones. If you have an iPhone, field test mode may be your best bet. However, signal strength readings through field test mode are not available on all iPhones, but it's worth a shot. If you have an Android, measuring signal strength through field test mode is just as easy as with an app.The field test method will differ depending on your operating system. We have an entire article on Field Test Mode, but here is a basic overview of how to check your signal strength straight from your phone.How to Find Precise dBm Readings on Your iPhoneThe Field Test menu has had some variations on each iPhone version; nevertheless, this mini-guide should work on most iOS systems. Note that it may not work on every phone. Open the Control Center (or go to the Settings app). Remember to turn off your Wi-Fi After you've done this, open the Phone app and insert the following, exactly as you see it: *3001#12345#* Press call and you will see the Field

It is not rare for people to set up an Access Point (AP) and then forget about its location. It is especially true in an office where there may be many access points hidden out of sight. Another possible scenario is that someone could set up a rogue access point with malicious intentions, and you wish to remove it.In all these cases, you will need to locate the access point. Usually, offices keep an inventory of the access points along with their location so that they can keep track of them. So, first, you should try looking if your office has such documentation.However, it is also possible that you don’t have access to such documents, or they don’t exist at all. In such cases, the only way to locate the APs so is by using spectrum or Wi-Fi analyzing programs, like WiFi Analyzer or directional antennas.Use Wi-Fi Analyzing AppsWi-Fi signals get weak as you move farther from the access point and stronger as you come nearer. You can use signal strength analyzing apps that use this property to locate the approximate location of the access point.Here’s how you can locate the access point using the Wi-Fi Analyzing app.Install a WiFi analyzing app on your mobile phone or laptop.Open it and get to the relevant Wi-Fi network name or SSID.Try turning off all the access points on the network you have already located first.Then, check the signal strength of the remaining access points and decide one access point to locate first. The signal strength is a negative value, so keep in mind that something like -60 dBm is lower than -40 dBm.The human body contains a lot of water (45-75%) which can weaken the WiFi signals. So place the device close to your body, just below your chest, to obstruct the Wi-Fi signal coming from behind.Stay in the location and orientation for a few seconds until the signal strength of the access point becomes stable.Rotate your body a little bit so that you are facing in another direction.Stay like that for a few seconds and check the strength again.Do so for all directions to find the direction that shows the highest signal strength.You can also decrease the Scan Interval to quicken the search process.Move a little bit toward that direction and perform the same process. Proceed to do so until you find that the strength gets to the maximum possible value. It shouldn’t change much, even when you face different directions. Also, keep the following things in mind:Usually, the signal strength will not go above -10 dBm on 2.4 GHz, -20 dBm on 5 GHz, and -30 dBm on 6GHz.Sometimes, other Wi-Fi devices or certain equipment like refrigerators, microwave ovens, etc.,

Our phone line. Should you need to purchase a cell phone signal booster, our team of professionals can help you find a cell phone signal booster that meets your needs such as your space requirements, your phone’s compatibility, and the best model to keep your phone working (regardless of whether it is an IOS Apple phone or an Android phone) with the strongest possible decibels.Comparison of signal strength in decibels vs. bars vs. practical experience.Signal strength is represented in -dBm format in the chart below from -60 to -110. This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. That means the closer the value is to 0, the stronger the signal. For example, -60dBm is better signal strength than -110dBm.Signal Strength in dBmPractical Signal StrengthGreater Than -60 or 5 Bars.Excellent signal. No chance of dropped calls. Optimal voice quality and data transmission speed.-60 to -75 or 4 Bars.Very good signal. Unlikely to experience dropped calls or quality issues that affect performance. This is usually the best available signal unless you're directly next to a cell tower or a signal booster interior antenna.-76 to -90 or 3 Bars.Good signal. While reliability and quality are generally adequate, interruption by building materials or other obstructions while moving could quickly deteriorate signal.-91 to -100 or 2 Bars.Fair signal. However, voice quality and data transfer speed may be noticeably affected. Dropped calls are more common.-101 to -110 or 1 Bar.Poor signal. Dropped calls and extremely slow wireless data transfer speed are constant problems.Less Than -110 or No Bars / No Service.No signal. There's no wireless connectivity possible without a custom solution.Since cell phone boosters require some signal in order to boost it or multiply it many times, there needs to be atleast "poor" or "weak" signal outside where donor antenna can be placed. Therefore, you can deduce from chart above that the minimal amount needed must be atleast within -101 to -109 dBm if on 3G network, and within -111 to -119 dBm on 4G / LTE network. However, the best estimate would be the median of those two which is approx. -105 dBm on 3G and -115 dBm on 4G LTE. This is absolute minimal signal strength in decibel milliwatts that is needed outdoor for any cell phone signal booster to help improve reception indoor to any minimum extent.What if you do not have enough signal to use signal booster?If you cannot garner minimal signal strength as stated using your directional antenna (survey kit), a cellular booster, bi-directional amplifier (BDA) or RF repeater will not work. In such instances, you may submit location details for a custom signal enhancing solution that would include a Small Cell, Microcell, Femtocell or active distributed antenna system (Active DAS). A site survey by SignalBooster.com team will be required to suggest the most effective solution that will resolve your wireless connectivity issues permanently.

Signal work with my phone?Different ways you may use your phone require different cell signal strengths. To make a call, -100 dBm is not ideal but will work. It becomes more difficult to maintain a wireless data transfer at the -100 dBm range.To enjoy optimal functionality on your smartphone or cellular-connected device, you’ll want a signal between -50 dBm and -80 dBm.When your cell signal is weaker than -100 dBm, it’s likely that you won’t have service without relying on a cell signal booster. If you’re not familiar with cell phone signal boosters and how they work, this guide to cell signal boosters offers a helpful explanation on how they make stronger cell connectivity possible.Test cell phone signal on an iPhoneiPhone cell phone signal strength appsFor iPhones, there are some helpful apps that you can download to test existing cellular signal strength and network speeds.The free weBoost App will help you test cell phone signal strength, find the nearest tower, get weBoost support, and install our boosters.
