W-DMX by Wireless Solution and lighting fixtures by Griven have been fitted to the exterior of the Sheraton Doha Hotel and Resort. The upgrade aims to enhance the waterfront skyline and the three-sided pyramid shape of the hotel.
The main façade of the hotel and the waterfront side are now equipped with Griven Powershine MK2 D RGBW. The waterfront side, as well as the lower part of the hotel terrace, have been enhanced by 43 units of Zaphir RGBW with wide and medium optics installed right onto the cornice of the roof. In addition, four units of Globe MK2 7000 CYM colour changing searchlights have been located on the roof of the hotel. The concrete arm of the hotel can be projected on using Gobostorm Plus MK2 and Zenith image projectors.
All the LED fixtures are managed from the control room using a Wireless Solution W-DMX system. The DMX signal starts from the control room located on the ground floor of the hotel and is transmitted via six W-DMX WhiteBox F-1 Transceivers to 10 WhiteBox R-512 receivers, managing a total of more than six DMX universes. The entire system is using 5.8GHz per request from the client as the 2.4GHz bandwidth was too heavily saturated and W-DMX is the only company that has the 2.4/5.8GHz Dual Band Function.
Danilo Bettinazzi, director of sales and marketing for Griven, explained: ”A W-DMX system was chosen for this project as it was necessary to manage and control lighting fixtures located in distant places and at a remarkable height. Moreover, the absence of cables and the possibility of controlling more than five DMX universes in a comfortable manner was a plus of the W-DMX system. In consideration of the top urgent completion schedule and of the peculiar architectural design of the Sheraton, all of the companies involved in this challenging project did a very good job.”
