Hi All!
Libelium sells this GPRS module for Arduino
www.libelium.com/tienda/catalog/product_info.php?cPath=21&products_id=59
Does anyone know what's the maximum throughput of messages with this shield i.e. how long does it take to send or read a message from GSM module?
I was thinking to replace a SMS GW (which now ties up a computer and a few handsets) with this but the system should be capable of sending / receiving a few thousand messages per hour.
