System Notes

Please see the WIKI for more information on this now active system.
The OpenSky system will be interoperable with DuPage County's emergency telecommunications network, the State of Illinois' STARCOM 21 digital communication system, and various mutual aid channels for public safety agencies, including police, fire, EMS and emergency management.

The digital communication network will consist of five sites and 10 channels, allowing for 50 simultaneous talkpaths. The radios that will be used by Naperville's first responders will be Project 25 (P25) Phase II-ready, 700/800 MHz multi-mode radios capable of operating on OpenSky, P25, STARCOM, EDACS® and mutual aid communication networks. Both the Naperville Police Department and the Aurora Police Department will house 'hot' standby IP switches to provide redundant reliability in the radio system's configuration. With NetworkFirst®, Naperville will have a cost-effective gateway that provides interoperability with other IP standards-based networks.

OpenSky offers digital voice and packet data communications using a high-performance IP backbone network. OpenSky's high quality digital voice trunking capabilities and packet data communications features directly address the needs of both utility and public safety users, and OpenSky is capable of expanding to meet future requirements. In addition, OpenSky networks are based on the widely-accepted IS-732 protocol to support mobile applications with end-to-end TCP/IP connectivity, simplifying application-to-network integration.
