Marketplace Development works with Concourse to update plasma-display advertisements in LaGuardia via Wi-Fi: Marketplace creates the current generation of airport retail spaces, managing them for the airport authority. The company uses plasma display screens to provide information, which includes advertising and travel information. By using Concourse's host-neutral Wi-Fi network, Marketplace can update the content on a much simpler basis. Every time you have to pull a wire or add a service in an airport, big dollars are involved because of the clearances for staff and the time of day when such work can be performed. Wi-Fi obviates cost and delays.
