Hi all, I'm looking for recommendations as to a suitable wireless technology that will allow data to be transmitted over distances up to 400m. Baud rate not a problem. It will be used outdoors around a Quarry site. Any thoughts? Zigbee? Standard 433MHz stuff? Dean [Non-text portions of this message have been removed]

Check out the B&B catalog. They've got whatever you need. It sounds like you're looking for small numbers so you may as well buy it instead of building it. http://www.bb-elec.com/

I use Aerocomm radio modems good for much greater distances. regards Mat Tubb Airship Solutions Pty Ltd http://www.airship.com.au/ Ph: 1300 791 068 Mb: 0415 150 414

Look at Digi.com - 900MHz $150 per radio with enclosure. XBee at 2.4GHz or 900MHz in a box or as a bare module: not as robust, but OK if you have line of sight or nearly so. --- In AVR-Chat@yahoogroups.com, "Dean Claxton" <deanclaxton@...> wrote: > > Data rate is not an issue - 1kbps is more than enough in this instance. > Basically it will be running remote warning signals. > > Dean > > On Tue, Jan 20, 2009 at 3:26 PM, dlc <dlc@...> wrote: > > > If you are outside and line of site Zigbee modules are good for that > > distance if they use the higher power amp outputs (XBee Pro for > > example), they are only a data rate of about 250Kbps however. > > > > DLC > > > > > > Dean Claxton wrote: > > > Hi all, > > > > > > I'm looking for recommendations as to a suitable wireless technology that > > > will allow data to be transmitted over distances up to 400m. > > > > > > Baud rate not a problem.

I stumbled across the Radiometrix NiM2T and NiM2R - priced at approx US$70 for the pair - seems reasonable and claim up to 500m range. Looks fairly simple to integrate - any thoughts?

If you are outside and line of site Zigbee modules are good for that distance if they use the higher power amp outputs (XBee Pro for example), they are only a data rate of about 250Kbps however.

Data rate is not an issue - 1kbps is more than enough in this instance. Basically it will be running remote warning signals.

Its radio so when claiming 500m range where 400m range is required day in day out, 500m isn't enough. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.

The nordic NRF(whatever) chips do pretty well. Last time I tested them with monopoles, I got good data at those sorts of ranges. Sparkfun and RFDigital carry good modules for them.
