1) It never goes as fast as they say it does
2) It never goes as far as they say it does

So they make sure you see the biggest throughput number that they can quote on all their marketing literature.

Tip! Tip: "Throughput" or "transfer rate" is the number of bits that move from one place to another in a given period of time. For wireless networking equipment, throughput is usually quoted in Mbps (Megabits per second).

This number, however, is usually the raw data rate, and is something that you'll never approach in your actual network. What number can you use? The answer is Rule 1A:

Rule #1A: Take the manufacturer's Mbps number and divide by (at least) two. Wireless Networking Need To Know 2006 | Tom's Networking
