LTE for Public Safety Networks

It is increasingly being recognised that effective communications are key to a successful response to emergency and disaster situations. The ability of the first responder emergency services to communicate among themselves and to share multimedia information directly affects the ability to save lives. This is reflected in increasing public investment in broadband public safety communication systems. These systems have some specific requirements, which are outlined in this paper. As LTE is expected to become the most widely deployed broadband communication technology, we examine the capability of LTE to meet these requirements, and identify possible future developments to LTE which could further enhance its ability to provide the necessary service.
