    The client program runs on your 6400 computer and communicates through the computer's radio over a wireless link to an access point. The access point then sends the client data to the server on the wired LAN.

  • Page 23: Characteristics Unique To Wireless Networking

    Roaming The 6400 computer's radio can connect to only one access point at a time. As a user walks around with a 6400 computer, the computer's radio must detach from the previous access point and attach to a new, physically closer access point to maintain a communications link with good signal quality.

  • Page 24: Out Of Range Communications

    This ensures that the client and server can communicate with each other at any time. If a user takes a 6400 computer out of the range of an access point for a significant time, the client server communication connection is put at risk.
