LTE

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 Public Safety 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 the FirstNet™ network core. FirstNet™ is responsible for consulting with states, local communities, and tribal governments to develop the requirements for its RAN deployment plan. All fifty states have elected to opt-in to FirstNet™.

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 when 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. 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 (the P25 standard CSSI interface) that provides instance access, without needing any donor phone.

Through this architecture, Catalyst provides interoperability between mission critical Push to Talk LTE cell phones and mobile radios. Catalyst Dispatch Consoles can also dispatch to both LTE cell phones and LMR portable radios with this architecture.
