Rodriguez, Michael Green, linux-wireless, wireless-regdb Cc: Johannes Berg, Kathy Giori, David Quan, John W. Linville FYI - European conformance spec for 5 GHz Radio LANs has some slight modifications which Johannes has pointed out which we have reviewed today in consideration for our new DFS design. The skinny is that our implementation of using 3 regions are OK and we will move forward with that. Below are some small meeting notes on this. EN 301 893 1.5.1 - new pulse patterns - in effect now (Michael will confirm) - all rules harmonized, all countries will use the same of set of pulse patterns. Countries won't be able to pick and choose, all countries must abide by this. EN 301 893 1.6.1 - isn't finished yet, it will take effect 6 months to a year to take effect. 0.8us pulse is what we support today, this spec pushes the narrower pulse width of 0.5us. Countries won't be able to pick and choose, all countries must abide by this. Based on our review today we are OK to keep the US, ETSI, JP categories for DFS regions. We also do not foresee any future changes which will break this design. The biggest wild card will be FCC which is currently reviewing DFS rules but as far as we can tell there is nothing on the roadmap to allow dynamic configurations for DFS parameters.

I just fear that will not allow us to keep manoeuvring effectively in the future, because then we need to change all the implementations, potentially old ones, rather than just updating the database. I wasn't so much thinking of the pulse patterns though as the other timings like the airtime allowed to use before moving onto a new channel. johannes ^ permalink raw reply [flat|nested] 8+ messages in thread
