WiFi7 throughput calculator | 802.11be data rate calculator

This page covers WiFi7 throughput calculator or WLAN 802.11be data rate calculator. This WiFi-7 data rate calculator mentions 802.11be maximum throughput formula.

EXAMPLE: 802.11be WiFi-7 data rate calculator:
INPUTS: BW = 320 MHz (Calculator calculates N_SD automatically) ,
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

Following formula or equation is used for this WiFI-7 Data rate or throughput calculation.

Following are the details of WiFi7 maximum throughout calculation as per 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.
