Innovative Research Helps Emergency Responders Better Communicate While Indoors
As part of its mission to improve communications for public safety, the First Responder Network Authority (FirstNet), an independent entity within the Commerce Department’s National Telecommunications and Information Administration (NTIA),identified improved in-building communications as a critical need for first responders and a required component of the nationwide public safety broadband network it’s been tasked with deploying.
Providing reliable coverage indoors is a long-standing challenge. The Institute for Telecommunication Sciences (ITS), NTIA’s research laboratory in Boulder (CO) has been researching in-building communications for many years, independently and as part of its Public Safety Communications Research (PSCR) partnership with Commerce’s National Institute of Standards and Technology. On July 31, ITS released a new report that describes the results of experiments conducted to investigate both the in-building coverage characteristics of future public safety mobile networks and ways to improve performance in such environments. This research not only can be used to help first responders better communicate during emergencies, but it also may help spur innovation in commercial wireless networks also interested in enhancing indoor coverage. This report provides preliminary data that can be used to begin effective planning of in-building public safety LTE communications. It also identifies additional research needed to reliably predict in-building coverage, and points to the need to enhance coordination of all aspect of a network. We look forward to continuing to work on this important issue with FirstNet and PSCR as we seek to provide public safety officials with the 21st century tools they need to help save lives.
