Where would you fit in with a highly directional antenna?
Please note that I have a really bad attitude about mesh networks. I
generally don't like them. I'll spare you my usual rant (mostly
because I'm tired and wanna get some snooze).
for some interesting test results and statistics from the MIT Roofnet
project. Not the large packet loss (delivery probability) and very
slow average thruput. That's typical.
Here's another mesh network status map:
If you tinker with the web page, some nifty statistics appear.
This one is a bit tricky to use:
Click on the various names on the upper right of the map so that they
switch to bold face type. The mesh will eventually appear, along with
path statistics. The percentages shows are the packet delivery
reliability. Lots of links show really high packet loss.
Anyway, get some numbers from your mesh network admin.
