LTE for public safety networks 论文

摘要

It is increasingly being recognized 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 article. 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 that could further enhance its ability to provide the necessary service.
