PAR Scope (2/2) k
This standard is an amendment to IEEE It addresses principally those applications such as critical infrastructure monitoring. It defines an alternate PHY and only those MAC modifications needed to support its implementation. The amendment supports: ' *(1) Operation in any of the regionally available licensed, license exempt, and special purpose frequency bands ' *(2) Simultaneous operation for at least 8 co-located orthogonal networks ' *(3) Application data rate of less than 40 kbits per second ' *(4) Propagation path loss of at least 120 dB ' *(5) >1000 endpoints per mains powered infrastructure ' *(6) Asymmetric application data flow ' *(7) Extreme difference in capabilities and performance between endpoint devices and coordinating devices (collectors) ' -coordinator may support all standardized modulations (MCS) and data rates ' -coordinator may be required to support antenna diversity or antenna beam steering ' -end point must be able to conserve energy ' *(8) Reliable operation in dramatically changing environments (no control over environment) This amendment also provides mechanisms that (9) enable coexistence with other systems in the same band(s) including IEEE , and systems.
SG4TV
This amendment specifies a physical layer for meeting TV white space regulatory requirements and also any necessary MAC changes needed to support this physical layer. The amendment enables operation in the available TV white space, supporting typical data rates in the 40 kbits per second to 2000 kbits per second range, to realize optimal and power efficient device command and control applications. It supports accepted methods of TV White Space coexistence in existence at the time of development.

PAR Purpose g
To provide a global standard that facilitates very large scale process control applications such as the utility smart-grid network. This amendment supports large, geographically diverse networks with minimal infrastructure. Smart Metering Utility Networks can potentially contain millions of fixed endpoints. The communication range, robustness, and coexistence characteristics required for this class of application have not been met with existing 802 standards k
The purpose of this amendment is to facilitate point to multi-thousands of points communications for critical infrastructure monitoring devices. The amendment addresses the application's user needs of minimal network infrastructure, and enables the collection of scheduled and event data from a large number of non-mains powered end points that are widely dispersed, or are in challenging propagation environments. To facilitate low energy operation necessary for multi-year battery life, the amendment minimizes network maintenance traffic and device wake durations. In addition, the amendment addresses the changing propagation and interference environments
SG4TV
The purpose of this amendment is to allow wireless networks to take advantage of the TV white space spectrum for use in large scale device command and control applications.

Compatibility
Distinct Identity
The : optimized for high data rates along with support for star network topologies with centralized control.
802.16: optimized for high data rate, point-to-point and point-to-multipoint network topologies, licensed band, TDM
The : support frame sizes of 1500 bytes in length and error detection of a two byte CRC
g (WNAN) requirements : low data rate (40kbps), unlicensed band, burst and asynchronous upstream traffic, star-topology as well as peer-to-peer
IEEE will not adequately support the low energy critical infrastructure monitoring application requirements
The current IEEE M2M PAR calls for changes to the MAC, and no substantial change to its PHY. it will not meet the large path loss, minimal infrastructure requirements, and multi-year battery life required by LECIM applications.
IEEE is intended to provide broadband services to rural subscribers, which does not address the need for multiyear battery life.
IEEE is designed for higher data rates which limit both range and battery life to less than that required by LECIM applications.
There are no other IEEE 802 projects, utilizing unused TV channels, specifically addressing
low data rate operation optimized for use in device command and control applications.
