Not all but most. Never make an absolute statement. I'm sure Fargo is at a decent saturation

3. Residential users are the cause of congestion
|
Usually, but they tend to be in close geographically areas and only affect a couple dozen people.

4. Residential and ISM users should work on different channels
|
Yes, and they can't be overlapping.

5. Residentiall users should be using wired access
|
No. I have wireless in my house. Of course my router is 12 foot in the air on a wall. Residential users need to be educated as to when it makes sense to use wireless over wired.

6. Most residential users don't change the channel from its default
|
Correct. As well as the SSID, password, etc.

7. Bluetooth is not suitable for SCADA
|
Not neccesarily. It does have a distinct purpose. If say you had a large piece of rotating equipment and didn't want to run all the I/O through a fingered roller you could install a bluetooth I/O unit on the equipment and send the I/O wirelessly to the PLC. There are other circumstances where it could be useful but you really need to plan it out beforehand.

8. 802.11a is only useful up to 100 feet

Don't know it's not very popular here in the states.

9. Intelligent channel selection in routers. For: 2, Against: 1
|
Yes. I'm seeing this more often. I believe the dd-wrt firmware supports this.

10. More channels should be added

11. Taxing access would go down like a lead balloon
|
The lead balloon analogy no longer works. We have a television show where they made a lead balloon and it floated.

12. Canada is probably a bit cold (as a Brit that doesn't bother me much - is it wet too?)

Not any more wet then most places but they do have dental plans (ok that was my one zinger)

A couple of other ideas to ease congestion:
- The beacon frame rate could be reduced
- The power limit could be reduced
