The system has built-in security, including VPN-like encryption between the device itself and Autonet's network operation center. In addition, the system also will work with corporate VPNs, Pratz said.

Initially, the primary audience will be both families and business travelers who rent cars, Pratz said. But, ultimately, he thinks the system would be attractive to corporate IT because it would enable mobile workers to stay in touch with the home office without needing to stop to find a Wi-Fi hot spot or other type of access.

"It should be very attractive to enterprises because it's secure but easy enough for anybody to use," Pratz said.

Pratz said that Autonet is technically a mobile virtual network operator, meaning it relies on a special type of agreement that allows it to offer its own service while using the facilities of existing wireless service providers -- in this case Verizon Wireless and Sprint.
