Bob – regarding 1.2.1,a – I believe they are referring to using existing camera interfaces as the receivers. I’ve read a number of the contributions – not enough to be conclusive, but the general thesis is one of one-way communication,
where the transmitter (light source) is often new, and the receiver is a camera already built into a device (e.g., a cell phone, a drone, or a vehicle). I’ll make an inquiry to find out. -george From: ROBERT GROW <bobgrow@xxxxxxx> Colleagues: This is a reminder of the 11 May 2020 802.3 ad hoc teleconference to review and comment as appropriate on PARs submitted by other WG. Meeting information can be found on the IEEE 802.3 call and meeting calendar
(http://www.ieee802.org/3/calendar.html). The P802.1CQ PAR extension and P802.1Q revision PAR have already been approved by the LMSC, so we will not need to review. That leaves two PARs from other WGs.
My proposed comments follow for your convenience. I look forward to your participation on the call. No comment. PAR I had one comment on 6.1.b. Because this is RAC related and previous ad hocs have suggested I submit such comments directly as the RAC Chair, I have already submitted the following comment to the EC reflector. Obviously, the WG could
choose to make a similar comment if felt necessary.
CSD 1.2.3 — Unexpanded acronym “OWC”. Please expand. 1.2.5,c — It is not likely that a many devices can be upgraded to use an optical transmitter and receiver with only firmware upgrade. At a minimum, the device needs the hardware for an optical transmitter and
receiver. Many of the devices cited in 1.2.1,b would be subject to extensive qualification of the new optical interface (e.g., automotive, biomedical, process control, etc.) This has significant potential impact to the economic feasibility of the retrofit
market. Some of the devices cited in 1.2.1,b may not be upgradable, for example low cost drones likely do not have replaceable modules for the communication interface. Device physical design may also not support the differences in radio propagation from
an antenna versus optical transmission from the optical transmitter (e.g., the device itself may provide minimal attenuation because of it materials to a radio signal but totally block optical transmission in certain directions, significantly changing the
operational profile for the device. 1.2.5,a — Again, "existing hardware" is not credible. It needs to be rewritten to perhaps to “hardware designs” or something that does not imply existing installed hardware. 1.2.5,b — Again, “billions of existing devices” is not credible and is not supported in the CSD. The first sentence has little relevance to “known cost factors”, delete it. To unsubscribe from the STDS-802-3-DIALOG list, click the following link:
