The comments are summarized below, and text changes are proposed. 1 1.1 Terminology Machine to Machine Communications > The language in the PAR scope and purpose seems rather heavily based around buzz words that don't have clear meanings. > Machine to Machine communication - all LAN communication is machine to machine in a reasonable sense of that term. (BTW, it isn't clear why Machine to Machine is capitalized in 5.2.) Even if you mean communication from machine to machine without a human directly initiating the transaction, much of internet traffic and data center traffic running on existing 802 networks fits that description. E.g. data transfers between servers, management monitoring, back-up. There should be a better term to describe communication with small automated devices for purposes such as observation and control. > Even if one accepts that "machine" means some sort of autonomous device such as cameras, sensors and controllers, the communication with them is probably person/computer to machine and vice versa rather than the machines chatting amongst themselves. It seems that the issues addressed are more the need to efficiently support lots of simple machines connecting to the network regardless of whether messages are going between machines or machine to computer. We propose some alternate names: ‘Automated Machine Communications’, ‘Autonomous Device Connectivity’, ‘Embedded Device Communications’, etc. 1.2 Human-centric > Human-centric - I've looked around and don't see any consistent use of human-centric in a sense that works here. It seems to mostly be used with regard to technology to refer to making technology easy to use for humans. You seem to be using it more in the sense of human initiated or human controlled. And again, much of network traffic is already machine initiated. We propose to adopt suggestion of ‘human initiated or human controlled’ to replace ‘human-centric’ 2 Distinct Identity > Regarding the 5 Criteria - Distinct Identity a): It isn't entirely accurate. The motivation for 802.3af Power over Ethernet standard was largely an enhancement to meet the needs of devices such as cameras, sensors and controllers so that they didn't require a separate power connection so there was a prior standard with the objective of providing for such devices. I'm not saying 2 IEEE C802.16ppc-10/0048 that your proposed work doesn't have distinct identity - just that the distinctness isn't as broad as your current statement. 802.3 already addresses large numbers of devices and very low power operation. Perhaps you can make your statement more accurate by qualifying it as applying to subscriber or wireless networks. We propose to add text around licensed operation, managed access, and wide-area coverage, which are identities unique to 802.16 family of standards. Text changes --------------------------------------------- Text Start Abstract: --------------------------------------------------- Automated Machine Communications PAR Form and Five Criteria 2.1 Title: Amendment to IEEE Standard for Local and Metropolitan Area Networks - Part 16: Air Interface for Broadband Wireless Access Systems – Enhancements to support Automated Machine Communications 5.2 Scope: This amendment specifies IEEE Std 802.16 medium access control (MAC) enhancements and minimal OFDMA PHY modifications to support automated machine communications [for purposes such as management and control of embedded devices]. The enhancements are lower power consumption at the device, support by the base station of significantly larger numbers of devices, extremely low latency, and efficient support for small burst transmissions. This amendment provides continuing support for WirelessMAN-Advanced Air Interface and legacy WirelessMAN-OFDMA equipment. 5.4 Purpose: To enable more efficient communications for a range of applications in which the device communications are automated rather than human initiated or managed. 5.5 Need for the Project: Many applications require network access for machines that involve communication requirements significantly different from those used to support typical human network access. Such applications include secured access and surveillance, tracking, tracing and recovery, public safety sensors, vehicular telematics, healthcare monitoring of bio-sensors, remote maintenance and control, smart metering, automated services on consumer devices, retail digital signage management. Distinct Identity Each IEEE 802 standard shall have a distinct identity. To achieve this, each authorized project shall be: a) Substantially different from other IEEE 802 standards. b) One unique solution per problem (not two solutions to a problem). c) Easy for the document reader to select the relevant specification. a) Substantially different from other IEEE 802 standards: This standard is unique in its objective of providing enhancements to IEEE 802.16 standard to support automated machine communications. Such capabilities are clearly distinct in terms of what’s provided in other standards because it requires unique enhancements like wide area connectivity, operation of devices in licensed bands, managed access, handling of extremely large number of devices, very low power operation, efficient support of very short bursts, etc. b) One unique solution per problem (not two solutions to a problem): There is no other standard in IEEE 802 that is specifically targeting automated machine applications specifically requiring cellular wide-area coverage at this time. So this is the only project that is targeting cellular machine type applications at this time. c) Easy for the document reader to select the relevant specification. 3 IEEE C802.16ppc-10/0048 The title of this standard and the scope is distinct enough for document readers to discern the application of this standard. ---------------------------------------------- Text End --------------------------------------------------- Reference [1] IEEE 802.16ppc-10/0003r6, Machine to Machine (M2M) Communication PAR Form and Five Criteria, May. 2010 4
