City Theatrical (CTI) has been granted US Patent number 7,432,803 for its wireless technology.  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 comments, “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 US Patent recognizes our contribution to this leading edge technology.”
