How to Easily Boost Your Cell Phone Signal at Home Chris Hoffman @chrisbhoffman July 29th, 2016 Poor signal strength could be your carriers fault, or it could be because of signalblocking materials in your homes walls.
A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink).
Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength will vary.
Cell phone signals are radio waves, the AMFM kind, that operate within a certain frequency: 50 decibels to 120 decibels (dBm). 50 dBm is great signal or full bars. 120 dBm is very poor signal or a dead zone.
May 02, 2016 My signal strength has dramatically decreased suddenly for about a month now, and can not find or been given a reason why or resolution options.
How signal strength is actually measured. The signal your phone receives from a cell tower is measured in decibelmilliwatts (dBm), a unit of electrical power in decibels (dB), referenced to 1 milliwatt (mW). There are three things you need to know to understand how decibelmilliwatts work: Your cell phones signal strength is measured in dBm, or decibel milliwatts, a standard unit of measure. dBm is typically expressed as a negative number, 88 for example. The closer to zero the reading is, the stronger the cell phone signal.
