Calculate and analyze your Wi-Fi 7 network performance.
Estimated throughput assumes a general network efficiency of ~70% to account for protocol overhead, interference, and other real-world factors.

The theoretical PHY (physical layer) data rate is calculated based on several key factors of the Wi-Fi signal. The formula is as follows:
Data Rate = (NSD × NSPS × R × NSS) / TSYM
NSD
Number of Data Subcarriers: The total number of tones within a channel that are used for carrying data. This number increases with channel bandwidth (e.g., 320 MHz has more subcarriers than 160 MHz).
NSPS
Number of Bits Per Symbol: Determined by the modulation scheme (e.g., 4096-QAM transmits 12 bits per symbol). Higher MCS values use more complex modulation.
R
Coding Rate: The proportion of the data stream that is useful data versus error-correction data. A rate of 5/6 means 5 bits are data for every 6 bits transmitted.
NSS
Number of Spatial Streams: The number of independent data streams transmitted simultaneously, directly related to the number of antennas used.
TSYM
Symbol Time: The duration of a single symbol transmission, including the Guard Interval (GI) which prevents interference between symbols. A shorter GI increases the data rate.
