LINK Research Digital Pre-Distortion Tees Off at British Open

At this year’s Open Golf Championship LINK Research’s latest wireless camera RF module, incorporating real time pre-distortion which offers adjacent channel performance and clean RF spectrum, was used for the first time by Aerial Video systems (AVS).

For such a large broadcast event, frequency spectrum allocation can be limited. To alleviate this situation AVS utilized LINK’s field changeable L1500 RF modules to provide flexible operation over the 1.4GHz and 2GHz bands. Even with this flexibility, when multiple wireless cameras are in operation adjacent RF channel operation becomes unavoidable. Despite this, AVS combined its operational knowledge with the adjacent channel performance of LINK’s pre-distortion RF module (L1510-1927PD) and L2174 receiver to give HD coverage of the entire 18 hole course with just four receive sites and six ground based camera transmitters operating at 100mW. A separate dedicated receive site was used with 20MHz LMS-T to provide outstanding aerial views of the actions.
