[lug] Wide Area Network Technology

[Stephen Queen]

We are trying to build an instrument that will have data collection
nodes spaced at varying intervals of up to a kilometer. The individual
nodes have an ethernet interface. We want each node to be able to
communicate with a central controller. We will use wireless where it
is feasible, but will also rely on some sort of connected protocol as
well.  The instrument will only be in place for a few days.

What sort of networking equipment or technology would lend itself to
this application?

Thanks,
Steve
