The software shows a graph which displays the network name, the type of security, the vendor, the signal, the channel, and the MAC address of listed networks. [5] A graph showing the history of signal strength can also be displayed. [4] It can be used to join listed AirPort networks without configuration and to join Bluetooth networks as well. [1]
"S9" signal strength, a strong signal, on the S meter of a typical ham or shortwave radio receiver: −80 dBm: 10 pW: −100 dBm: 0.1 pW: Minimal received signal power of wireless network (802.11 variants) −111 dBm: 0.008 pW = 8 fW: Thermal noise floor for commercial GPS single-channel signal bandwidth (2 MHz) −127.5 dBm: 0.178 fW = 178 aW
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.
Netspot supports 802.11n, 802.11a, 802.11b, and 802.11g wireless networks and uses the standard Wi-Fi network adapter and its Airport interface to map radio signal strength and other wireless network parameters, and build reports on that. NetSpot was released in August 2011.
As part of the wireless site survey, the effective range boundary is set, which defines the area over which signal levels needed support the intended application. This involves determining the minimum signal-to-noise ratio (SNR) needed to support performance requirements. Wireless site survey can also mean the walk-testing, auditing, analysis ...
