The Public Safety Distributed Antenna System (DAS), also known as the Emergency Response Radio Coverage System (ERRCS), includes any system that provides wireless services through the antenna system, especially for buildings, to ensure that emergency responders can maintain wireless communication within the building structure and at work in the event of an emergency. When it comes to public safety, men and women are often the first to arrive on the scene, so it's crucial to enable emergency communications. In the event of a crisis, people such as building owners who need to ensure the safety of people under the building or authority should also do the same.
