Slow ODBC 3.0 and 4.0

We want to use an wireless application which should be connected to Navision. Our first idea was to bulid an application on the wirless devices (Barcode scanner) in PHP. For the connection we wanted to use the ODBC driver. We tested the ODBC drivers 3 and 4 . Both are very slow in the connection and therefore not really usable for our purpose. Does anyone know about a similiar functionality/standard software for wirless devices and connection to Navision DB or how the ODBC could work a lot faster ? Thanks

Try C/FRONT, it is a lot faster.
