WiFi 7 Throughput Calculator | 802.11be Data Rate

This page provides a WiFi7 throughput calculator, also known as a WLAN 802.11be data rate calculator. This tool helps determine the maximum throughput achievable with the 802.11be standard.

This WiFi-7 data rate calculator utilizes the 802.11be maximum throughput formula.

EXAMPLE: 802.11be WiFi-7 Data Rate Calculator:

• INPUTS:

  • BW = 320 MHz (The calculator automatically determines N SD)
  • N CBPS = 12
  • Code rate = 0.833
  • N SS = 16 (For 16x16 MIMO)
  • Symbol period = 12.8 µs
  • GI = 0.8 µs

• OUTPUT:

  • IEEE 802.11be Maximum throughput = 46.099 Gbps

WiFi7 Throughput Formula as per IEEE 802.11be

The following formula or equation is used for the WiFi-7 data rate or throughput calculation:

Details of WiFi7 Maximum Throughput Calculation

The following are the details of WiFi7 maximum throughout calculation as per the formula mentioned above.

• NSD (Number of data subcarriers as per bandwidth) = 234 (20 MHz), 468 (40 MHz), 936 (80 MHz), 1960 (160 MHz), 3920 (320 MHz)
• NCBPS (Number of coded bits per OFDM symbol) in bits = 1 (BPSK), 2 (QPSK), 4(16QAM), 6(64QAM), 8(256QAM), 10(1024QAM), 12(4096QAM)
• Code Rate (R) = 1/2, 2/3, 3/4, 5/6
• NSS (Number of Spatial Streams) = 2, 4, 8, 16. NOTE: For no spatial stream, enter 1 here as input.
• Symbol time duration is fixed to 12.8 µs.
• Guard interval (GI) duration can be 0.8, 1.6 or 3.2 µs.
