Alternate Communications

Started by Scott Lingerfelt December 28, 2003

I have been looking for alternate means of collecting remote data. I
currently utilize the internet for data collection and finding it very
difficult to get onto many customer LAN's. I am looking for alternate
wireless methods such as satellite, cell network, or radio transmission.
Can anyone recommend any low cost methods with low monthly cost or no
monthly cost? I have looked at utilizing SMS, Microburst, and Satellite.
Anyone with experience with any of these? Any tips? Any recommendations?

Thanks in advance,

Hi
 
It varies a bit from country to country as I am in NZ it will depending what the networks are based on.  If only GSM then you have to make do with SMS.  If CDMA as we are then you are in heaven.
 
We have been using mobile (cell) comms for many year for scada systems.  SMS works OK but the last year we switched to CDMA solutions.  Many countries use GPRS on this.  You basically pay for the data you send and it is technically considered ONLINE.  This has it's funny quirks though.  We use packages that are specially adapted for telemetry apps with low data transfers per day.  It's very cost effective and I know transport operators also use this.
 
regards
Martin

We use Falcom & Wavecom modems and I would highly recommend their webs and products.  Do not exactly know what you mean with aggregator but we use the tcp/ip stack inside the modems to limit code size in the uC.
 
Also to be considered is the CSD or HSCSD that are normally found on GSM networks.  This is very easy to get started and you use it in the same way as a normal landline modem.
 
Falcom has a selection of manuals on their site for downloading.

I have used a cellular phone modem for remote access to a people counter,
interfaced to an 18F PIC and communicating with a desktop PC fitted with a
standard modem. It worked very well although making the software robust -
dealing with things like dropped carrier etc. - was a bit tricky. I didn't
use SMS, I simply transmitted the data.

It's very cheap in terms of running costs. I used a Siemens modem, I think
it was an M20 or something like that.
