OEM units containing modems


I’d be very interested in locating a source for an OEM device such as:

O ready-boxed unit containing a wireless module supporting open-AT and possibly embedded SIM.
O wide-input-range power supply 9-30V or so.
O IP-65 to 67 packaging.
O External RS232 or even RS485 serial port
O CE marked, and UL if possible.

Is there a good place to look for suppliers of ready-to-use units containing SW modems?


Something like this? (maybe not IP65, is that important?)



Following on from tomridl’s suggestion, could you use a Fastrack or GL6100 mounted into an IP-65/67 box…?
