What does dBm tell me?

The signal strength is indicated with negative numbers in decibels milliwatts (dBm) measured. The higher the measured value (i.e. closer to zero), the stronger the signal. A value of e.g. -50 dBm is a very good signal, a value of -113 dBm represents a very weak signal with GSM / UMTS.

How does a WLAN antenna radiate?

1.2 How emits a wifi-Antenna off? The shape of a antenna influences the radiation characteristics. The simplest antenna form is the omnidirectional antenna or ... With a rod antenna, the electromagnetic waves spread in a circle around the center of the antenna out.

What does dBm mean for WLAN?

A dBm (Decibel milliwatt) is the logarithmic value for the signal strength, e.g. for data transmission in WIRELESS INTERNET ACCESS. This value describes the strength of the transmission signal of a transmitted or received signal in relation to one milliwatt. ... This reference point is at dBm 1 mW.
