Typically, a reading of -50 is the strongest signal, while the reading below -100 dBm is considered to be very weak.

The closer to zero the reading, the stronger the cellular signal. The reading of dBm is expressed as a negative number. How can we measure our cell phone signal received from the cellular tower? The answer is decibel-milliwatts, or dBm – a standard unit of measure used to define signal strength in wire and cables at radio and audio frequencies. There will be quite a bit of fluctuation between the bars on one phone to another phone owing to the different cell phone manufacturers (Apple, Samsung, Sony, etc.) Why is it?Īctually, signal bars are merely an aesthetic representation of the signal strength. But you might face such occasion during daily life that your cell phone reminds you of losing service while the signal bar you can see is above 3 or more. The price for installing a commercial-grade Wi-Fi solution scales depending on the number of access points needed for coverage and capacity.Īs long as you have an Internet connection, we will take care of the rest.For the most time, we get used to evaluating signal strength by comparing how many signal bars or dots on our cell phone screen. We will help determine your priority areas, trouble areas, number of access points needed, where best to place them to provide the coverage you need. If your WiFi strength is suffering, consider upgrading to our best solution yet! Let’s get started!Ĭall to set up your consultation with one of our Wireless Experts from. 90 dBm is unusable:Ĭore Cabling now offers Ruckus Wireless, Cisco, Ubiquiti and other vendors wireless network infrastructure for both indoor and outdoor commercial areas. The best signal you can receive is -30 dBm. While also a measure of signal strength, dBm is unlike RSSI as it is an absolute number representing power levels in milliwatts. In other words, RSSI is a value for determining a good wireless connection. RSSI, or “Received Signal Strength Indicator,” is a measurement of how well your device can hear a signal. We understand your frustration, and our Core cabling and wireless team can help. Are you annoyed with your WiFi signal? Have you unplugged, rebooted, and shaken your devices trying to improve the connection to no avail?
