Airports are all about connection—connecting loved ones, connecting businesses to clients, and connecting travelers to the next flight. To make these connections, travelers often rely on cellular connectivity. Whether they are making business calls between flights or notifying someone of their arrival via text message, they need a reliable indoor cellular signal. Travelers also need the peace of mind that comes with knowing they can call for help from anywhere—a public concourse or a parking garage—if it is ever needed. And, it's not just passengers who benefit from reliable indoor cellular coverage, it is also employees and first responders. Airports are sprawling places; cell phones and private radio networks are critical for keeping workers connected. Moreover, first responders need dependable access to public safety frequencies during critical situations. However, ensuring a reliable connection indoors is difficult without the right technology—a distributed antenna system (DAS) provides that connectivity.
