Mobile Application and Data Isolation

Ongoing
The security of mobile devices operating within a nationwide interoperable network is critical in maintaining a secure and reliable cellular network for first responders. The inclusion of mobile devices erodes traditional network boundaries, increasing a network’s threat surface, and adding many new

Mobile Cloud Computing

Ongoing
Design robustness using formal language This effort develops a formal specification using the π-calculus to define a virtual device representation. It also describes a way to compose multiple virtual devices representing physical devices available on the network to build a composite virtual

Neighborhood Area Communication Network

Completed
The smart grid is comprised of many networks (domains) with various boundaries that have to be interconnected to provide end-to-end services. The challenge is to design network architectures that can meet the interoperability requirements for inter-domain and intra-domain communications, as

Network Modeling for Public Safety Communications

Ongoing
Advances in broadband wireless technologies developed by standard developing organizations (SDOs) such as 3GPP and IEEE 802 offer unprecedented capabilities that have the potential to improve the effectiveness of first responders. Our efforts are aimed at evaluating how well emerging solutions meet

NextG Channel Measurement and Modeling

Ongoing
NextG Channel Measurement NIST has designed and assembled a number of mmWave channel sounders: from the first generation of electronically switched horn antenna arrays, moving to virtual phased-array, and most recently we are transitioning to real phased-array channel sounders. Several features make

NIST Cloud Computing Program - NCCP

Ongoing
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction
NIST Industrial Wireless Systems 5G Testbed

NIST Industrial Wireless 5G Testbed

Ongoing
The NIST 5G Industrial Wireless Testbed project aims to revolutionize industrial connectivity by deploying and evaluating the capabilities of 5 th generation (5G) wireless technology within an industrial setting. This initiative responds to the emerging demand for ultra-reliable, low-latency
Johnson Noise Thermometer system

Noise Thermometry

Completed
The project has also created a quantum-based electronic temperature standard that uses the ACJVS in conjunction with measurement of the Johnson noise -- random electrical noise caused by thermal agitation in a conductor -- in resistors at arbitrary temperatures. This Johnson noise thermometry system

Open RAN Interoperability

Ongoing
Open RAN aims to enable components from different vendors to work together seamlessly. However, integrating elements from various suppliers poses technical challenges. It requires thorough testing, standardization, and collaboration to ensure that hardware and software work together seamlessly. This

Open RAN Research at NIST

Ongoing
Network Disaggregation An Open RAN gNB is a decentralized gNB and consists of three parts, each with its own hardware/software: Radio Unit (RU); Distributed Unit (DU); Control Unit (CU). Each unit in Open-RAN takes over a section of gNB tasks. The RU has the responsibility of transmitting and

Optical Two-way Time-frequency Transfer

Ongoing
Researchers in the Fiber Sources and Applications Group have been developing the technique of “Optical Two-Way Time-Frequency Transfer” (OTWTFT) which can link time between distant clocks to the femtosecond level over free-space links. Optical clock networks could enable tests of fundamental physics

Out-of-Band Emissions Measurements of LTE Devices Operating in the AWS-3 Band

Completed
The project, proposed by Edwards Air Force Base, measured Out-of-Band (OoB) emissions from new Long Term Evolution (LTE) systems operating in bands adjacent to existing incumbent Department of Defense (DoD) Aeronautical Mobile Telemetry (AMT) systems used at government test and training ranges (TTRs

Physical Layer Design and Evaluation

Ongoing
IEEE 802.11ay Physical Layer Modeling and Simulation NIST has developed models and simulation frameworks to evaluate the physical layer performance of IEEE 802.11ay under different channel environments based on real measurements. NIST IEEE 802.11ay EDMG Physical Layer Mode, implemented in MATLAB

Power Conditioning Systems for Renewables, Storage, and Microgrids

Ongoing
Objective: To establish standards and measurement methods, and test for smart grid and microgrid Power Conditioning Systems needed to transition from today’s low penetration of nondispatchable intermittent renewable energy sources to flexible grid operations that can actively adjust to varying grid

Power Quality Measurements and Fault Detection and Identification

Completed
Traditionally, disturbance detection relies on customer calls to the utility and through the SCADA (Supervisory Control and Data Acquisition) system. A major disadvantage of SCADA is that the measurements are not synchronized, which means that the fault detection process is not precise or timely

Precision Timing for Smart Grid Systems
