ICT Today: Public Safety and Cellular In-Building Wireless – Separated or Integrated

September 22, 2016

One of the reasons for poor radio frequency (RF) penetration is that new buildings are designed to minimize energy consumption. These green buildings often incorporate additional insulation, tinted windows and other technologies that, while reducing energy consumption, also significantly attenuate in-building wireless signal penetration. To help improve this situation, a distributed antenna system (DAS) is often installed to ensure that users can talk, text, browse the internet and stream videos without interruption. Not only is cellular coverage and capacity required; to add to the challenge, another group of users require wireless communications. Public safety personnel such as firefighters, police and other first responders depend on the ability to communicate to each other in the event of an emergency situation both for their own safety and the safety of the community they serve.
