Is that a valid reason? Can’t we just evolve the standard later? - Does that match the need? Is the benefit worth the trouble / risk? - That is the key issue!

It addresses principally outdoor Low Data Rate Wireless Smart Metering Utility Network requirements. It defines an alternate PHY and only those MAC modifications needed to support its implementation. Specifically, the amendment supports all of the following: Operation in any of the regionally available license exempt such as 700 MHz to 1 GHz or the 2.4 GHz band. Data rate of at least 40 Kbits per second, but not more than 1000 Kbits per second Achieve the optimal energy efficient link margin given the environmental conditions encountered in Smart Metering deployments. Principally outdoor communications PHY frame sizes up to 1600 octets Simultaneous operation for at least 3 co-located orthogonal networks Connectivity to at least one thousand direct neighbors characteristic of dense urban deployment Provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE 802.11, 802.15 and 802.16 systems.
