Firefighters and policemen must have access to critical infrastructure in the venues like fire hydrants, utility panels , tunnels and underground dressing rooms. Ambulances should have clear RF signals when entering tunnels and passages. Private security personnel must be connected when helping people exiting the locations and protecting those hiding in comm rooms or basements.

Metros must be fast but, above all, safe. Worldwide cities are becoming more urbanized and metro transportation is a priority for citizens’ mobility. At the end of 2017, there were metros in 178 cities in 56 countries, carrying on average a total of 168 million passengers a day. Across the country and around the world, smoke and fire are common hazards in subway systems and thousands of incidents are reported annually. While the majority of incidents are minor, first responders cannot take the risk and perform large scale evacuations of platforms and stations. In any kind of emergency, they need to be fast and efficient and communication between personnel both in the tunnels and outside the station is mission critical. Fiplex Public Safety Signal Boosters and DAS products improve underground coverage areas maximizing RF communications at stations and tunnels.
