City Theatrical Gains U.S. Patent for Wireless DMX

Posted on Thursday, October 23rd, 2008

City Theatrical, a world leader in the design, development, and manufacturing of wireless DMX, has been granted U.S. Patent number 7,432,803 for its wireless


Wireless DMX is used in entertainment technology to control a wide variety of electronic devices including moving lights, dimmers, fog machines, and color changers, without the need for running data cables. City Theatrical’s wireless DMX is similar in concept to a home or business WiFi system, but uses a much more robust and powerful radio transport method to ensure reliability of mission critical systems.

CTI’s patent covers the transmission of DMX, RDM, and ACN via the means of FHSS (frequency hopping spread spectrum) radios as well as DHSS (direct sequence spread spectrum) radios, in the 2.4 GHz range. Also covered are the bi-directional broadcast of data, and the concept of a remote monitor for RDM and ACN.

City Theatrical’s President, Gary Fails commented, “This patent is the result of over seven years of product development effort by Larry Dunn and Paul Kleissler, beginning when they were both independent engineers consulting with CTI, and leading to them joining the company, Larry in 2003 and Paul in 2007. We have put thousands of hours of effort into our wireless DMX products like our multi award-winning SHoW DMX™, and this U.S. Patent recognizes our contribution to this leading edge technology.”

Does this mean City Theatrical will own DMX by wireless?
