Wi-Fi Data Throughput
In addition to signal strength and channel contention limitations, there are additional factors that reduce
achievable data rates from theoretical maximums which are advertised. The advertised rates do not
account for protocol overhead that Wi-Fi connections must exchange for security and reliability, nor do
they account for any high-layer protocol (e.g. TCP/IP) overhead.
Lastly, these theoretical rates compute combined upstream and downstream traffic; since Wi-Fi is half-
duplex, the rate in one direction is reduced to accommodate traffic in the reverse direction. Thus, while
the advertised rate for 802.11g is 54 Mbps, a robust channel operating at max capacity will deliver
approximately 20 Mbps of application data in one direction.
