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
Strength of a graph Strength of a graph In the branch of mathematics called graph theory, the strength of an undirected graph corresponds to the minimum ratio "edges removed"/"components created" in a decomposition of the graph in question. It is a method to compute partitions of the set of vertices and detect zones of high concentration of edges, and is analogous to graph toughness which is defined similarly for vertex removal. The strength formula_1 of an undirected simple graph "G" = ("V", "E") admits the three following definitions: Computing the strength of a graph can be done in polynomial time, and the first such
