Re: [AFMUG] When you want 4.8 kbps at -115 signal or thereabouts

I've been looking at this technology for out of band management of
sitemonitor-connected devices for about 6 months now.   I mentioned this
briefly in another thread, without naming the technology directly.

Waiting for my preferred silicon vendor to complete the US certification on
their modules before getting started - they're already shipping European
modules.

Note that the C/I is in negative dB's.   That is, you need a signal
something like 20dB BELOW the signal level of any interferer.

There is actually a fairly big opportunity for WISP's here... this system
is designed in a cellular-like model.  The LoraWan protocol is designed so
a company like a WISP could install several AP's and then sell connectivity
services across them to entities who will use it.   The protocol is also
encrypted so the WISP only has access to the data needed to authenticate
the Lora end devices and not the actual payload data.   Because this is set
up very much like a cellular network (with things like a 'core'), I was
expecting the price to be very prohibitive - instead it's amazingly
inexpensive.

yes, particularly where you can install a base station/central hub in an
area and get data from your things for "free"...  Much less costly over a
10 year timespan than putting a SIM card in a SCADA device with quad band
cellular modem, which will probably be at minimum $10/mo per active SIM in
bulk (from a T-Mobile MVNO reseller) plus data billed by usage, figure
another $4 to $5 per month for a tiny amount of data.

There was a company that had a 2.4GHz narrow band unit that would go 7 miles.  
I looked for them a few months ago and couldn’t find them.

This technology seems like it would be perfect for SCADA stuff wouldn't
it?  We provide service to our local irrigation company and they have
terrible connections, but only need a few kbps every few minutes so it
still works great.  They are just sensors that monitor water flow through
canal systems.  I can see a ton of uses for this technology as the IOT
takes off.

Yepwe use allot of 900MHz FHSS and narrowband radios with just 9600bps
or less...we have used 2 .4 maxstream where several 900MHz links already
existed.
