Architecture : mix of technologies What and where are your applications? Local area: HAN, NAN Last mile: End points to backhaul; WAN Middle mile: Spread across the grid Complex Systems  tightly integrated What are the requirements? High or low throughput needs Latency concerns in the application Security: Regulatory compliance; now and in the future Level of intelligence; criticality of the data  It will take different solutions & technologies … no panacea Communication layers MESH, PLC, Cellular/WiMax, WiFi, ZigBee Different application, different network topography, different solution

Total Cost: impact of installation and maintenance (source : Beecham Research 2009)

Why a public Cellular WAN? Available everywhere –Extensively used all over the world –More than 5 billion active connections –Covers 99% of the population Proven communication technology –Existing standard, –More than 15 years existence –Secure networks –Seamless and secure IP connectivity –Access to back up with several public network Costs –Installation: Public network offer the lowest installation cost –Maintenance: Leverage on investment: billions will be invested by public network to main it –Technology cost: Access to a technology ecosystem HW technology reaching costs of other comms. technologies (PLC, private RF)

Key Challenges Assuring connectivity that is secure, easy to maintain and compatible with future needs over the system lifetime. Supporting the diverse environment, dense and sparse populations and making the best use of existing and future networks Using existing open and standard technologies to minimize the cost of installation and maintenance Lower risk

Comprehend the big picture  Entire network Plan for growth and scale Consider modularity Plan for change of technology Reliable communications are essential 2-way in many cases IP connectivity Security Long life span Rugged and Proven technology Network lifespan Installation and Maintenance: Possibility to monitor communication equipment Possibility to upgrade the protocol stack with a secure patch mechanism Checklist for a successful project
