signal strength

[′sig·nəl ‚strəŋkth]
(electromagnetism)
The strength of the signal produced by a radio transmitter at a particular location, usually expressed as microvolts or millivolts per meter of effective receiving antenna height.

signal strength

In radio, a measure of the received radio frequency power, generally expressed in decibels relative to some standard value. Normally, it is either 1 milliwatt or that power which would have resulted at the same distance under free-space transmission. The normal measure for signal strength in voice communications is 1 to 5; 5 is the strongest, as in “receiving you strength 5.” Also called field strength.

However, the received signal strength is interfered by various types of noise, such as band interference among access points, sudden person walking and opening or closing of windows and doors, and so on.
It continued: "Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don't know it because we are erroneously displaying four or five bars.
Apple, which is based in Cupertino, California, said it will fix its signal strength formula to conform to other AT&T phones through a free software update for iPhone models 3G, 3Gs and 4 within a few weeks.
Apple said that when users were noticing a dramatic drop in the number of signal strength bars on their phone's display it was likely due to weak network coverage in that area.
According to Apple its formula used to calculate how many bars of signal strength to display is wrong, sometimes resulting in two more bars being displayed than should be for a given signal strength.
Consider the cell phone: The signal strength increases or decreases depending on the distance from the phone to the cell tower.
