doc.: IEEE f Submission May 11, 2009 René Struik (Certicom Research)Slide 3 IEEE nan PHY Requirements Alternate PHY amendment –MAC additions only where needed to support PHY License exempt frequency bands –No bands listed explicitly Low data rate: 40 kbps to 1000 kbps Optimal energy efficient link margin given the SUN environmental conditions –Principally outdoors, but also in basements, around corners… PHY frame sizes up to a minimum of 1500 octets Potentially dense deployments: at least 1000 direct neighbors Simultaneous operation for at least 3 co-located orthogonal networks Good coexistence mechanisms (both ways) References: [1] g-phy-parameters-for-15-4g.doc [2] nan-wnan-par.doc

Utility sector: Dense deployments – many neighbors in close proximity Rural deployments – neighbors far away Support for IT infrastructure at higher layer (e.g., IP-based) – larger frame sizes Utility sector can live with mains-powered applications: Source: PAR, §5.2: up to 1W in some regulatory regimes These requirements may not be unique for utility sector!

doc.: IEEE f Submission May 11, 2009 René Struik (Certicom Research)Slide 5 Other applications These requirements may not be unique for utility sector! Examples: Energy sector: oil/gas pipelines (think: pipelines in Nigeria, Alberta, Russia) Mining sector: mine shafts, open mining Environmental monitoring: migration of species, biodiversity studies in tropics Defense/military applications, sabotage-resistant node placement Container handling and dispersed asset control Other: e.g., avoiding repeater by “stretched” communication link. Commonality: not always power source!
