Digital IDAS simulcast radio system & signal distribution via DAS (distributed antenna system)

The award winning and much discussed Al Bahr towers in the U.A.E. capital housing the Abu Dhabi Investment Council headquarters, are featuring unique dynamic facades which open and close throughout the course of the day in response to the (sun) light conditions with the purpose to shade the surface of the buildings. This will help reduce heat from the sun while reducing the use of costly air-conditioning without compromising visibility and views from inside the buildings. The challenge here was to provide a radio communication system which could provide seamless communication from any radio to any radio while the users are roaming in and around 2 office towers of each 145 meters high standing 50 meters apart, including the 2 underground basement levels. The solution chosen is a so-called Simulcast Repeater system. In each tower Lambda installed an multi-channel digital IDAS conventional radio repeater system with ICOM IC-FR6000 series radio repeaters and high quality combining equipment from UK based manufacturer Axell. This is complemented by a battery-back up system for ultimate redudancy in case of a power failure. The repeaters are supported by a Distributed Antenna System throughout the towers and basements. The two repeaters are connected by fiber IP link so that upon receiving a radio message they re-transmit simultaneously and consequently ensure complete coverage with radio signals throughout both towers and through all parking areas. The system is complemeted with Digital UHF Portable Radio's having everything one expect in a business radio, such as superb digital audio clarity, IP54 and MIL-STD-810F rugged construction, a long lasting battery, verbal channel announcement and more then enough channels (16)..
