Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals.
Ever increasing operational demands on first responders, along with new technological opportunities and capabilities, are driving PublicSafety and other Critical Communications Organizations to adopt broadband technologies such as Long Term Evolution (LTE ) for mission critical data. While access to broadband data is improving public safety operations and providing new applications, voice remains the most critical communications capability.
In March 2017, U.S. Department of Commerce Secretary Wilbur Ross announced that the First Responder Network Authority will partner with AT&T to build the nation’s modern, mobile broadband LTE network for first responders. The construction of the nationwide FirstNet network requires each state to have a Radio Access Network (RAN) that will connect to FirstNet’s network core. FirstNet is responsible for consulting with states, local communities, and tribal governments to develop the requirements for its RAN deployment plan. Each state will have the option to either allow FirstNet to create the RAN or to “opt out” and create its own RAN. Even if a state chooses to opt out and receives approval from the Federal Communications Commission (FCC) to develop its own RAN, the RAN must use the FirstNet network core and must meet FirstNet requirements.
Catalyst technology is particularly well suited to participate in FirstNet, as we can help organizations migrate to FirstNet and also provide effective interoperability between FirstNet, P25, DMR and legacy radio networks. As FirstNet moves forward Critical Communications organizations are deploying PTT over LTE using commercial networks such as AT&T and Verizon Wireless as well as private LTE networks. These organizations are benefiting from the large coverage area that commercial carriers offer and the ability to use a single device for PTT, video, text, email, and countless other applications.
Catalyst led the deployment of 3G Broadband PTT dispatch and interoperability solutions in the early 2000’s as it partnered with Verizon Wireless. Catalyst has built on its 3G technology and experience helping Critical Communications agencies implement Broadband PTT to create dispatch and interoperability solutions for LTE. For example, Catalyst is a certified partner of Kodiak Networks, the PTT applications provider for AT&T, Verizon Wireless, Sprint, and others. Catalyst integrates with Kodiak via a wireline IP interface that provides instance access, independent of a donor phone. The wireline interface supports multiple simultaneous talk groups and does not rely on a single cellular tower site for access. Catalyst can provide wireline interoperability with mobiles radios including P25, DMR, NXDN, SmartNet®, and EDACS with only our IntelliLink Gateway; a console is not required. Catalyst’s wireline solution for LTE is installed and being used by Critical Communications users today.
