Wired/Wireless Network Connection

Vault Micro introduces the innovative ‘Vault Connectivity Software – SAP over IP,’ a solution that revolutionizes the way telematics and other devices connect within a vehicle. This system allows devices such as telematics units to utilize a SIM card in an Ethernet/IP-enabled device, eliminating the need for each device to have its own separate SIM card.

The SIM Access Profile (SAP) traditionally defines the protocols for accessing a SIM card via a Bluetooth link. Expanding on this concept, our ‘Vault Connectivity Software – SAP over IP’ provides a cutting-edge IP-based SIM connectivity solution, leveraging the Ethernet network within the vehicle for streamlined and efficient communications.
