WiFiScan shows Wi-Fi signals that Waste Energy, Waste Wireless Spectrum, Contribute to Wi-Fi network Congestion. Operational levels (RSSI) are taken from manufacturers data specifications - Dlink, Fortinet & Cisco. Energy Wasting Wi-Fi signals benefits no one. They contribute to network congestion, waste energy and waste wireless spectrum.
RSSI Levels and Technology Developments
20 years ago when 802.11g and Wi-Fi Protect Access (WPA) were introduced. Depending on make/model of AP / Router, RSSI levels ranged from -66dBm to -73dBm for 54Mbps data rate (2003 - 2004).
Due to technology advances, 54Mbps data rates can now be achieved with lower energy/signal exposure e.g. RSSIs' of -77dBm (Fortinet) and -82dBm (Cisco 9130).
This means lower energy, and lower signal intensities provide the same, or faster data rates.
WiFiScan uses max levels of -70dBm, which is 5 times greater than Fortinet (-77dBm) and 16 times greater
energy than a Cisco 9130 (-82dBm)…
Wi-Fi Technology improvements mean lower energy levels needed today

RSSI example:
-70dBm = twice signal intensity compared to -73dBm (54Mbps Dlink, 2003)
Examples of Excess Energy/Signal Requirements
Using RSSI -70dBm as the baseline (2.4GHz):
-60dBm = 10x signal energy/intensity
-50dBm = 100x signal energy/intensity
-40dBm = 1,000x signal energy/intensity
-30dBm = 10,000x signal energy/intensity
When compared to -77dBm multiply by 5 e.g. -30dBm = 50,000 excess signal energy/intensity
When compared to -82dBm multiply by 16 e.g. -30dBm = 160,000 excess signal energy/intensity
When compared to -98dBm, multiply by 580 e.g. -30dBm = 5.8million excess signal/energy requirements (note: -80 = 10x, -90 = 100x and -100 = 1000x ergo -98 = 580x)
