UCLA Public Safety Network Systems

Group Areas    

Group 1: Communication Equipment


Group 2: Networking Gear
The main responsible of the group is to identify and thoroughly describe the network requirements for public safety networks. Equipment covered by this research area involve service aggregation routers and any other devices used to interface with mobile operators and the network. All communications traffic will ultimately be routed to an IP-based metropolitan network. The key issue is maintaining interoperability between legacy and newer communications technologies.

Group 3: Networking
Group 3 focuses on the networking aspect of the PSNS. We are probing the proper requirement for routing and switching algorithm and policy for public safety network, and how to communicate information cross all layers of the network. It is especially important to deal with network management in order to control public safety communication alongside with other commercial communication. We must guarantee the public safety organizations a higher priority to access the network. The public safety network should also be capable to recover from any down connection.

Group 4: Architecture
The purpose of group 4 is to establish which devices go in each layer of the seven layer protocol and establish interoperability between all of them. Once we have established the type of device that goes into each category, we may have to alter the structure of the device in order to work seamlessly with the other devices on the network.

Group 5: Application and User Interface Designs
This group is responsible for designing future applications that utilizes the full potential of the LTE Network for Public Safety Agencies (Fire Department, Health Department, Police Department, etc.). Such examples include the possibilities for firefighters to download the schematic design of the building, the police officers to identify the type of drugs, and the medical personnel to diagnose patients at any location. Currently, we are researching disastrous past events, for example 9/11, Haiti Earthquake, Hurricane Katrina, New Zealand Earthquake, etc., in order to create applications that can be used to minimize the impact in similar future events. Also, we are looking through existing applications used by current Public Safety Agencies in order to find improvements and to incorporate it in the new applications.

Group 6: Testing and Performance Modeling
The Testing and Performance Modeling Group addresses the efficiency and effectiveness of an implementation of a Public Safety Network System. Our team will utilize testing equipment CAD tools to identify the key characteristics and trade-offs of the communication devices used. In particular, we will be looking at the transmission rate, the quality of service, and the security features offered by such devices. The results of the laboratory analysis will later allow us to draft recommendations for public agencies.
