Airbee Wireless Files Patent Application for System and Method for Data Transmission
Airbee Wireless announced that it has filed a patent application with the U.S. Patent and Trademark Office entitled “System and Method for Data Transmission.”
This is another major step in the evolution of Airbee’s patent pending, ZigBee compliant software stack for short-range wireless voice, data and video communications, addressing a global market that independent market research firms predict will exceed $8 billion annually by 2008.
The application describes “a method and system for a power optimal coding scheme used in data transmission,” and it is the first of several Airbee patent filings planned for the coming months.
Since the end of July when the ZigBee Alliance released the ZigBee standard for comment by its members, Airbee’s technical team has been especially busy integrating minor adjustments into the company’s software products, which are being readied for formal interoperability testing by an independent testing laboratory.
According to the abstract of the invention, Airbee’s new coding scheme “provides for the transmission and reception of asynchronous data using a first in first out driven serial port. In one embodiment of the present invention, preamble and synchronization word patterns are selected such that the start bit of the first byte of data that follows the synchronization word synchronizes with the start bit clocking signal of the baseband receiving serial port. Thereafter, the data stream will be in sync with the serial port.”
