Received signal strength indication link like other metrics such as travel time measurement (time of arrival). Received signal strength indication In telecommunications, received signal strength indicator (RSSI) is a measurement of the power present in a received radio signal. RSSI is usually invisible to a user of a receiving device. However, because signal strength can vary greatly and affect functionality in wireless networking, IEEE 802.11 devices often make the measurement available to users. RSSI is often derived in the intermediate frequency (IF) stage before the IF amplifier. In zero-IF systems, it is derived in the baseband signal chain, before the baseband amplifier. RSSI output
14 Signal Regiment (Electronic Warfare) warfare support to NATO and to the British elements under its command, this as a result of the formation of the Allied Rapid Reaction Corps. Changes in the organisation of the British Army caused the Regiment to move its Headquarters and two of its three field squadrons (226 and 245 Signal Squadrons) to Osnabrück, in April 1993. The third field squadron, 237 Signal Squadron (Electronic Warfare), moved to Hullavington, England at the same time. In December 1995, the German-based elements moved again, to Cawdor Barracks near Haverfordwest, Pembrokeshire, and 237 Signal Squadron joined them six months later after an operational
