The strength of the radio waves in a wireless network.
1. In radio, a measure of the received radio frequency power; generally expressed in decibels relative to some standard value, normally either one milliwatt or that power that would have resulted at the same distance under free space transmission. Could also be applied to the strength of an optical signal transmitted or received by a lidar or an acoustic signal transmitted or received by a sodar. The term field strength is commonly used as a synonym. 2. In radar, the strength of the received signal, usually expressed in logarithmic power units, in particular decibels relative to 1 mW, that is, dBm.
The strength and volume that a target produces as it is scanned and sensed by the search coil.
When you use your GPS device, it will have a signal strength. This is how strong the contact between your GPS device and the satellites in orbit are. Areas such as tunnels, caves and black spots, are renown for having very low or no signal strength.
A feature of the receiver, whereby the relative strength of the signal being received is indicated either visually or audibly. Visual indications are by means of a digital or analog meter. Audible indication is by the pitch or loudness of a tone. The signal strength depends on the current in the target line and its depth among other factors.
Signal strength is used to describe how powerful the received signal is. In satellite reception systems signal strength is usually measured at the output of the LNB.
In telecommunications, and particularly in radio, signal strength is the measure of how strongly a transmitted signal is being received, measured, or predicted, at a reference point that is a significant distance from the transmitting antenna. It may also be referred to as received signal level or field strength. Typically, this is measured as signal electric field strength of voltage per length or signal power received by a reference antenna.
