Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3] The concept can be used in wireless data networks to disrupt information flow. [4]
Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.
A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols (such as Bluetooth, Zigbee, near-field communication, Wi-Fi, NearLink, Li-Fi, or 5G) that can operate to some extent interactively and autonomously.
The signal-to-interference ratio (SIR or S/I), also known as the carrier-to-interference ratio (CIR or C/I), is the quotient between the average received modulated carrier power S or C and the average received co-channel interference power I, i.e. crosstalk, from other transmitters than the useful signal.
