Mobile Network Technologies:
Bringing the Internet and interoperable applications to vehicle systems

The patents in Cellport’s Mobile Network Technologies portfolio, granted from 1995 to 2003, make it possible to have bi-directional data communications between closed and dissimilar vehicle networks, wireless devices and the users’ applications and to use a vehicle-based server to extend Internet-based communications to a vehicle’s networked components. The MNT patents can enable countless Web applications for bi-directional use of Internet search, vehicle performance meters, crash sensors, the anti-lock brakes controller, navigation and search resources.

Core architectural patents included in the portfolio include the Dynamic Digital Bus that facilitates bi-directional data transmission between a wireless device and peripheral devices in a vehicle, such as the engine control unit, air bag controller, brakes, GPS positioning device, video displays and speech recognition systems; the Vehicle Server that converts Internet resources to vehicle protocols to communicate with the vehicle’s systems and subsystems; two vehicle-based router technologies, Link Select Router and Link Select Extended, which give service providers or users the ability to select from and use various types of wireless networks for transmitting and receiving data; and the Mobile Application Platform, an open architecture that makes it possible for sophisticated software applications to interoperate over a diversity of innately incompatible systems, including in-vehicle and wireless data networks, Web browsers and the Internet and human interface systems, and to control and display the applications.

The technologies enabled by the MNT portfolio have opened up a world of cost-effective universal Internet-based telematics applications, including communications and emergency services for consumers and businesses, navigation products, vehicle tracking and routing systems, fleet management, entertainment services, and others.

The Cellport MNT portfolio has created a US$5.5 billion market for Internet-connected vehicle hardware and services market in Europe, the Americas and Asia. Current licensees, including Continental and Motorola, have used the MNT intellectual property.
