[OLPC Networking] Wireless Recommendations (Ricardo Carrano)

[Greg Smith]

Hi Ricardo,

Interesting page with some great ideas. A few comments and questions 
after a quick read through.

- It looks like you are making recommendations for development that 
should be done to improve the wireless networking. I can't quite tell if 
these are test cases, or suggestions for new code or suggested action 
items for volunteers. You may want to clarify that.

- If your focus is on scale you should define the scale targets. You may 
  want to start with my modest goals defined at: 
http://wiki.laptop.org/go/9.1.0_Collaboration_Requirements#Scale

- You should tie each item in to a specific network environment. I 
suggest this list as the four key environments we want to support: 
http://wiki.laptop.org/go/Networking_scenarios

- You should tie each item in to a specific use case. We seem to get 
lost in the technical jargon on this subject and lose site of the end 
user. As a result we never quite end up with something we can promise 
people will work :-( I suggest you tie the items in to these use cases: 
http://wiki.laptop.org/go/Use_Cases#Collaboration_Examples but any 
specific example of what the user does down to mouse clicks at the 
activities level will work.

HTHs. BTW great work lately on performance analysis. I look forward to 
meeting you when you get to Cambridge, MA.

FYI as soon as I get a chance (before end of next week for sure) I plan 
to post a Motorola PPT explaining how they do a wireless site survey. 
Unicast me if you want an early look. Great stuff from the wireless 
experts and real results from a survey they did in Colombia for use with 
XOs, including a BoM for covering a whole town.

Thanks,

Greg S
