Eclipse ham prep

[Louis Mamakos]

E-911 calls will generally preempt normal cell phone traffic (or have 
access to some standby capacity) on mobile networks.  The mobile 
networks can also free up radio capacity on cell sites by dropping or 
reducing bandwidth allocations for data traffic.

I got a chance to see some interesting cell network usage data during an 
earthquake in New Zealand some years ago.  (I was working for 
Alcatel-Lucent at the time, and they had a bunch of their equipment in a 
mobile operator's network in NZ.)  The earth moves, everyone picks up 
their phone to call someone.  The network remained stable because those 
signaling components were engineered for overload situations.  Usually 
the weakest link is control plane/signaling traffic since the radio 
channels can easily be reallocated very quickly.

This is also ignoring any GETS capability that might exist in those 
networks.
