One way to look at this is that the "type of event" is not at all
important to communicate.  The real thing to get across is the available
capacity has changed somewhat dramatically.  Does it really matter if
this is because 802.11 dropped us from 11mbps to 2mbps or some BoD
system just allocated us a ton of capacity or we moved much closer to
some access point / basestation and now have a much better signal?

Does this make sense?
