We used this unit at a company meeting to move USB devices from the back of the control room to the stage in the front of the room. We connected our presentation clicker receivers to this unit so the clickers don't have to travel more than 150 feet to the receiver. We have found that when a room fills up with people who have cell phones in the 2.4GHz band, the clickers stop working due to interference. This problem was alleviated by having clickers next to the presenters.
