700 MHz Public Safety Broadband Network (PSBN)

• A transformational national capability

• Canada very active since 2010

• Key tenets – Interoperability, affordability, sustainability, efficient use of spectrum, 24/7 availability

• Band 14 (758-768 MHz D/L, 788-798 MHz D/L)

Emerging Wireless Technologies for Public Safety

• Need to solve the everywhere!

• In-building communications

• New wireless infrastructure could be different wireless technology; different wireless network…HetNets

• Internet of Things

• Next Gen Wireless (3GPP, WiFi)

• Service continuity (session persistence)

• Data science14

What EWIPPS Will Enable

16

• S&T research• Heterogeneous networking

• 3GPP to non-3GPP session persistence• Outdoor-indoor communications

• Sensors, IoT and IoLST• Assess impact (loading, …) of IoT and IoLST , “smart” stuff

• 5G and WiFi• Millimeter wave• PSBN offloading (3GPP to 3GPP)• Identify/address gaps specific to public safety communications needs

• Data science• Analytics (trends/patterns ➔ prediction ➔ automation)• Processing (retrieval, storage, aggregation, fusion, manipulation, transformation)• Data mining, modeling, classification

• Machine learning, cognition

• Test and evaluation capability

• Experimentation and demonstrations

Thanks!!
