WiFi 6 Range Measurements
Initial Measurement Results for WiFi 6, March 30, 2023
WiFi 6 Range Measurements
Measuring WiFI 6 Range with an iPhone 14
To measure 2-way WiFi 6 range with an iPhone 14.
An iPhone sends an ICMP Echo Request.
A WiFi 6 module receives the request and sends an ICMP Echo Reply.
Measuring WiFi 6 Range with a WiFi 6 Router
We will measure the range with a router and publish the results in the near future.
Measuring WiFi 6 Range with another module
We will measure WiFi 6 range with an identical module when Nordic SDK supports AP mode.
Fresnel Zone and WiFi Range
When WiFi signal is reflected by a surface inside the first Fresnel zone, it arrives at the receiver out of phase with the direct WiFi signal and reducing the signal amplitude. If there is no obstruction inside 60% of Fresnel Clearance Zone radius, signal reduction is small.
Fresnel Zone and Long Range WiFi Transmission
Fresnel Zone radius and clearance for WiFi signal for various distance is listed below.
Fresnel Zone Clearance Radius for 2.44 GHz and 5.5 GHz WiFi signals
Scottsdale Arizona Test Site and Measurement Method
Scottsdale Test Site, 3200 meters without obstruction except ground.
This test site is a straight dirty road without tree for 2400 meters. There are some low bushes in the last 800 meters.
