INTERFACE APPARATUS AND METHOD FOR WIRELESS DATA COMMUNICATION
First Claim
1. An apparatus for controlling data communications between a component interface port and a wireless network transceiver, the apparatus comprising:
- means for receiving digital data from the component interface port;
means for attaching a data unit overhead including source and destination addresses to the digital data in order to generate a data unit, the source address being a predefined data address for the apparatus and the destination address being a stored data address; and
means for outputting the data unit to the wireless network transceiver for transmission to a wireless network.

Abstract
Interface apparatus can be designed to allow wireless connections to be established between a computer and a computer controlled component such as a printer, scanner, etc. These interface apparatus do not require any modifications within the computer controlled component, as the interface apparatus is coupled to the computer controlled component via a standard interface such as a Universal Serial Bus (USB) cable. The interface apparatus converts data information from a first format required by the standard interface into a second format required by a wireless data network, and vice versa. With the use of such interface apparatus numerous wireless private networks can be established including both computers with wireless data connections and other components that normally cannot attach and/or remove data unit headers.
