This is not any different from the police tailing a suspect. Your whole argument is that they should not be allowed to use technology to do so. Well, what about using binoculars to see further? Or about using radios to coordinate multiple officers on the tail? All of these acts are done without warrant and without knowledge of the suspect. You must be one of those people who do bad things and don't want to get caught. I say, let them follow me if they want. It's sure to be a rather boring day for them.
OK, so I rented 10 compact cars from Hertz and had each one motor on up to 50 mph. Tomorrow I might try to get them up to 80 each for an 800 mph demonstration. Think I can patent this?
First of all, 11MBS is the bit rate on the air interface. NOT the actual throughput achieved by an end user.
1st problem: Overhead. If the test was run using FTP, there is FTP overhead, TCP overhead, IP overhead, and 802.11 overhead. (In the neighborhood of 80 bytes per packet)
2nd problem: 802.11 is NOT a full duplex connection. This means that whenever an acknowledgement is being transmitted by TCP, no other data is actually being transmitted on the network. Thus, the sending client has to wait for the channel to clear befor transmitting more data, limiting the throughput even more.
3rd problem: 802.11 overhead traffic. The 802.11 protocol calls out a lot of overhead packets that are not found on wired LAN's. For example, Beacons, RTS, and CTS signals that are used by the end stations to access the network.
As you can see, with all these limitations, 4 MBPS application throughput is about the best you will ever see in a single client environment. As more clients are added to the network, throughput actually decreases depending upon how active the others are.
