Public Safety Broadband Network Architecture Description

Abstract : WHAT PUBLIC SAFETY NEEDS IN AN EMERGENCY IS A public safety-controlled network with the ability to efficiently access and share accurate and timely voice and information during all stages of an event in any geographic location with the appropriate resources, interoperability, robust and reliable capacity, based upon the needs of the responders, and with the ability to dynamically scale to changes in the situation. 16 This document describes the network architecture for a Canadian public safety broadband communications network expected to operate in the 700 MHz band. It aligns with the governance model as currently endorsed by the senior officials responsible for emergency management in Canada (SOREM), which contains two layers of operational responsibility a national entity and multiple regional service delivery entities (RSDE). The network architecture is also aligned with the service delivery model whereby the users of the public safety broadband network (PSBN) are clients of the RSDE, while also being owners of the information networks. The PSBN interfaces with several external networks. The network architecture describes, at a high level, how the PSBN could interface with selected external networks. Furthermore, it is expected that Canadas public safety community will rely on deployable systems to deliver broadband services to isolated areas of the country where no broadband communications infrastructure exists and to areas where the infrastructure has been damaged. There is a section dedicated to the topic of deployable communications.
