integration. It has an integrated SIM card holder as well as a standard RF connector type MMCX. The concept
of the integrated modem has been defined to integrate on a sole device:
·
a single connector has been used that is standard and easy to find (it is supplied worldwide);
this connector includes all of the modem’s analog and digital connections
·
One standard easy to find RF connector. See RF connector section in
