Wi-Fi 8 Total Latency Calculator & Formula : 802.11bn

This page provides a WiFi8 total latency calculator, also known as a WLAN 802.11bn end to end delay calculator. Total latency in Wi-Fi 8 networks is a critical performance metric that encompasses various delay components including transmission delay, propagation delay, processing delay, and queuing delay.

This WiFi-8 total latency calculator utilizes the 802.11bn total latency formula.

EXAMPLE: 802.11bn Wi-Fi 8 Total Latency Calculator:

Scenario: A factory robot needs to receive a 1500-byte command in under 500 microseconds (0.5 ms) with minimal jitter.

• INPUTS:

  • The user defined maximum allowed latency = 500 µs
  • Jitter tolerance = 50 µs
  • Packet size = 1500 bytes
  • Data rate = 20 Gbps
  • Distance to AP = 15 meters
  • Time Wi-Fi 8 device wait for clear channel = 100 µs

• OUTPUT:

  • Transmission_Delay = 0.6 µs
  • Propagation_Delay = 0.05 µs
  • Total Latency = 100.65 µs

Results Interpretation:

• Is 100.65 µs ≤ 500 µs ? Yes.
• Is 10 µs jitter ≤ 20 µs ? Yes.
• The calculator would output: “Link is viable for this deterministic application.”
