How is range of signal measured?
Cell phone signal strength is measured in decibels (dBm). Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. In general, anything better than -85 decibels is considered a usable signal.
What is good signal strength?
Ideal Signal Strength For higher-throughput applications like voice over IP or streaming video, -67 dBm is better, and some engineers recommend -65 dBm if you plan to support mobile devices like iPhones and Android tablets. Minimum signal strength for reliable packet delivery.
Why do you need to do a range test?
Performing a range test will give an initial indication of the expected communication performance of the kit components. When deploying an actual network, multiple range tests are recommended to analyze varying conditions in your application.

How is signal strength measured in decibels on your cell phone?
Cellular signal strength is measured in decibels (dB), and typically range from -50 dB to -110 dB. The dB scale is logarithmic. This means that every 3 dB increase doubles the power.
How many spikes per second in signal detection?
Just to be really concrete, we could mark the horizontal axis in units of firing rate (10, 20, 30,…, etc. spikes per second). This would mean that on a noise-alone (no tumor) trial, it is most likely that the internal response would be 10 spikes per second. It is also rather likely that the internal response would be 5 or 15 spikes per second.
