Experimental Physics and
Industrial Control System

I am contemplating a project which requires wireless communication.
I would like to have telemetry information on a control station.
The network link specification is: range 1 mile at 250Kbps
Latency could definitely be an issue (measurement needed at this point)
I could potentially have several 250Kpbs links (not sure whether they can be 'trunked' together)

The remote device could run an IOC (I need something like a 'fast' sequencer for sure)
Between local OPI and remote IOC, I can use any communication protocol I want

Classic architecture:
local OPI ---- (CA over wireless) --- remote IOC
is there a way for an OPI to bypass the UDP discovery process and force connection to a specific IP addres/port?

Other possible architectures:
* mirroring of IOC
 local OPI --- (CA)--- local IOC -----(CA over wireless?) ---- remote IOC
How can you mirror an IOC, PV to PV ? (PV names need not be the same)

* 2 processes with duplicate queries
local OPI ---(CA)--- local IOC ----(serial protocol over wireless) ---- controller to remote hardware 
The remote IOC is independent from above and need to query the hardware as well
Maybe IPC could help reduce the number of 'real' queries?

* custom development (with Robot OS, aka ROS, or equivalent)
local OPI ---(CA)-- local IOC --- (serial protocol over wireless)--- non IOC software, i.e ROS
Make sense, but learning curve...

Any input?
