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)

Why another PHY?
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!

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!

Wishlist:
Add requirements facilitating ubiquitous computing (“internet of things”):
Should allow multi-year battery operation with style duty cycle and same “application topology”
Should have range/power consumption trade-off: with style range, should allow similar power consumption
