Wi-Fi connection failures from devices and access-point pairs with more than 50% signal quality

Description

A Wi-Fi access point (AP) is networking hardware that allows other Wi-Fi enabled devices to connect to a wireless local area network (WLAN). When users cannot connect to an AP, their machines display a connection error message and will not have access to the WLAN or Wi-Fi.

Measure attributes

Attribute	Value
Audience	Targeted HWIDs and CHIDs
Time period	7 days
Measurement criteria	Device / AP pair aggregation
Minimum instances	1,000
Passing criteria	<= 6% of Instances have connection failures to APs
Measure ID	40722983

Calculation

1. The measure aggregates telemetry from a 7-day sliding window into a percentage of instances where a device fails to connect to an AP

   1. An instance is a pairing between a device and unique AP; per device, the measure aggregates every attempted connection to a unique AP.
   2. The measure does not aggregate any device–AP pairs if their signal strength is below 50%.

2. A connection failure is counted as 100 and a connection success is counted as zero

Final calculation

Connection failure rate of device–AP pairs = average(all instances)
