Tulsa firefighters spent three days providing relief and support to Joplin-area residents, Ellis said.
"The equipment worked great and the experience we gained during the multi-day deployment to Joplin, you couldn't get that anywhere else," Ellis said.
Meanwhile, the 800 megahertz system provides a seamless frequency that connects first-responders along the I-44 corridor. The system brings additional, emergency coverage for 70 percent of the state's population from Lawton to Vinita, said Lacey Callahan, spokeswoman for Oklahoma Office of Homeland Security.
Known as the Oklahoma Wireless Information Network, the radio channel allows emergency workers to respond faster and to communicate with other jurisdictions during a multi-jurisdiction response.
Installing and maintaining the 800 meghertz system has cost about $61.7 million, Callahan said.
