IEEE SA - P802.15.4k - IEEE Draft Standard for Local and metropolitan area networks—Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs)Amendment 5: Physical Layer Specifications for Low Energy, Critical Infrastructure Monitoring Networks

This standard is an amendment to IEEE 802.15.4. 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 *Operation in any of the regionally available licensed, license exempt, and special purpose frequency bands ' *Simultaneous operation for at least 8 co-located orthogonal networks ' *Application data rate of less than 40 kbits per second ' *Propagation path loss of at least 120 dB ' *>1000 endpoints per mains powered infrastructure ' *Asymmetric application data flow ' *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 ' *Reliable operation in dramatically changing environments (no control over environment) This amendment also provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE 802.11, 802.15 and 802.16 systems. (See explanatory notes in Section 8.1)
