With the ever-increasing availability of commercial jamming equipment, the risk to public safety communications has never been higher. While public safety has operational backup plans for communications, jamming has proven problematic to detect in the field. The purpose of this project is to solve this critical problem of detection and characterization simply and seamlessly, for the first responder, the incident commander, and the system operator. In this project, Epiq Solutions will develop technology based on its miniaturized unique and commercially successful software defined radio (SDR) in conjunction with network detection and decoding capabilities. The key innovations made during the execution of this project are: the development of an effective detection algorithm for RF jamming waveforms of interest, the prototype development of a small, unobtrusive, power-optimized RF interference detection sensor leveraging Epiq Solutions' existing efforts in small form factor SDR, and the development of a sensor network architecture to support geolocation of RF jamming signals of interest via distributed sensors. Today public safety has few options to detect jamming, spoofing, and denial-of-service in its RF communications. The development of a small, unobtrusive detection tool provides a broad use case and will greatly reduce the risk to public safety in critical situations.

Interoperability has been a communications objective for for first responders in the United Stats for many years. The need for digital interoperability brought about the establishment of the Telecommunications Industry Association (TIA) Association of Public Safety Communications Officials (APCO) Project 25 standard in 1989. Today, P25 standards are very mature, and include an Inter-RF Subsystem Interface (ISSI) which allows interconnection of P25 standard systems. As LTE is commercially available, a number of proprietary broadband Push-To-Talk (PTT) solutions have seen substantial operational uptake and have arguably made the problem of interoperability worse. These Pre-MCPTT services are often communications islands with few if any provisions for interoperability. With the allocation of 700MHz spectrum to a nationwide, interoperable LTE network and creation of Firstnet a new generation of interoperability is now needed. A final challenge to MC LTE-LMR interoperability is the fact that 3GPP defines the Mission Critical Interworking Function (IWF) as out of scope of the standards. This leaves a blank space between LMR and MC LTE. The purpose of this project is to develop the requirements, feature sets, architecture, and design analysis to establish the feasibility of a Universal Interworking Function (UIWF) that closes the gap between standards-based MC LTE and P25 ISSI as well as establishing solutions for MC LTE to Pre-MCPTT and other LMR system types.
