![]() ![]() It becomes more difficult to maintain a wireless data transfer at the -100 dBm range-particularly at 4G or LTE speeds. To make a call, -100 dBm is not ideal but will work. How does cell signal work with my phone?ĭifferent ways you may use your phone require different cell signal strengths. In situations like that, simply convert the number to a negative. In field test mode, some phones may show the dBm measure as a positive number. So, a cell signal that measures -76 dBm is twice as powerful as a cell signal that comes in at -79 dBm. Being a logarithmic unit of measure, each 3-dB increase is actually doubling the power. The typical range of measure for cell signal strength is between -110 dBm and -30 dBm. See the cell signal strength chart below for a great comparison: Excellent signal strength = -64 dBm to -50 dBm.Good signal strength = -65 dBm to -84 dBm.Poor signal strength = -85 dBm to -100 dBm. ![]() The closer to zero the dBm reading is, the stronger the cell phone signal. What is a good signal strength for a cell phone? On a signal strength meter, dBm is typically expressed as a negative number-such as -88. Signal strength for cellphones is calculated using dBm (or decibel milliwatts) as its standard unit of measure. How is cell signal strength measured accurately?ĭecibels offer a more accurate and useful measure of cell phone signal strength. However, to make sense of this reading, let’s get an understanding of how signal strength is measured and how to do a cell phone signal strength test. Just like a car’s gas gauge, signal bars can only provide a general idea of signal strength- not an exact measure.Ĭhecking your mobile phone’s actual signal strength is better than relying on bars alone. This means the two signal bars showing on your model of iPhone may actually show that your phone is receiving more signals than your friend’s Android phone that’s currently displaying three signal bars. Some phones assign different values to each bar graphic. And isn’t entirely representative of signal strength. The truth is, the number of bars you see on your phone can vary greatly and often depend on the manufacturer and model. On your iPhone or Android-along with any other cellphone or cellular-connected device in between-the signal bars are mostly there to provide a visual representation of cell signal strength. But it hardly provides a complete picture. It’s an easy to understand point of reference. Wifi Analyzer Network Analyzer - empowers its users to analyze the status of WiFi networks, discover devices connected to WLAN, and pinpoint network issues, among other things.If you ask most people about the current quality or strength of their phone’s cell signal, regardless of their carrier, and they’ll probably give you one of the following responses:.Ubiquiti WiFiman - empowers you to optimize your home or office network with its intuitive user interface and reliable features.Scany - use it to detect all network devices, find network path bottlenecks, scan predefined and custom ports, and more.Network Analyzer - this free WiFi channel scanner app for iPhone and iPad offers a lot of essential functionality in a compact package.NetSpot - is an easy-to-use WiFi channel scanner app for iPhone and iPad.Here are the three best WiFi channel scanners for iOS. Still, there’s a lot that a capable iPad or iPhone WiFi channel scanner can tell you, including your internet speed, network name, signal strength, channel, router MAC address, security settings, and more. The App Store is home to many WiFi channel scanners for iPhone and iPad, but they all share one important limitation: they can’t analyze live WiFi data of any other network besides the one you’re currently connected to - at least not without an additional hardware device connected to your iPhone or iPad. ![]()
