I need your help in exploring my options for communications from our remote site. It is in the mountains (50km south of Revelstoke BC, Canada)
with no cell phone coverage and closest phone line across the lake (~5km) - but it's a long distance phone call anywhere from there. Two issues need to be resolved with this new solution:
1. Continous data availability DNP3 data... the utility requires us to provide them with exception reporting (if no exception occured every ~2 minutes we are to give them status)
2. The solution is to provide us with data/fax lines that will be used for dialup control and also as a phone connection.
Currently we are using one set of microwave radios that we communicate across the lake and have 6 phone lines from there (towers are in place). This system works pretty good but needs a backup (redunduncy) and would become too expensive if it were to be used on 24 X 7 basis (with long distance charges) for the DNP3 data.
The main focus is reliability.... the communication lines must be open (i.e. ready/ available) 99% of the time... with maximum outage of no longer than 15 minutes at a time.
I am open to any suggestions: radios, satelites, magic black boxes that do it all, teleportation... Any ideas? What do you use?
