Jun Tian, Ph.D., is a manager in Exponent's Computer, Data & Security Sciences practice with over 20 years of experience in wireless and wired networking, RF analysis, embedded systems, and communication security. She advises technology companies, legal teams, and government clients on system architecture evaluation, protocol analysis, and vulnerability assessment.

Dr. Tian has technical knowledge and experience relating to architecture definition, design, development, and verification. Her core competencies include:

  • Technical Investigations & Failure Analysis
  • Networking & Communications Systems
  • Real-Time Embedded System Software
  • Cybersecurity & Vulnerability Assessment
  • RF Engineering & Analysis

Wireless & Wired Networking

Dr. Tian provides consulting on the design, evaluation, and troubleshooting of wireless and wired network systems, with deep expertise in Wi-Fi (IEEE 802.11 standards including Wi-Fi 6 and Wi-Fi 7), satellite communication, and cable access networks (DOCSIS). She advises clients on network architecture optimization, protocol design, interoperability testing, and new product integration. Her experience spans both the technical standards, including IEEE, ANSI, and CTIA, and the practical engineering challenges of deploying them at scale.

Dr. Tian has served as a technical expert and industry liaison to major standards and certification bodies, giving her a distinctive perspective on how products are evaluated against published specifications and where gaps in compliance or performance arise.

Security & Vulnerability Assessment

Dr. Tian helps clients identify and address security weaknesses in communication systems, including wireless networks, embedded platforms, and connected devices. Her work encompasses vulnerability analysis, security protocol review, and the development of countermeasure test suites for Wi-Fi and related communication technologies. Her background in satellite communication payload design, including requirement analysis, interface design, and network resource planning, extends her capabilities into space-based and long-haul communication architectures.

She has led industry-wide vulnerability studies in collaboration with ecosystem vendors, producing actionable recommendations and test methodologies that have been adopted as industry guidance. This work is directly relevant to clients facing product liability disputes, regulatory scrutiny, or intellectual property challenges involving the security of networked systems and communication protocols.

RF Analysis

Dr. Tian conducts radio frequency (RF) analysis across a range of communication systems. Her RF expertise encompasses signal characterization, interference analysis, spectrum management, and the evaluation of RF performance against applicable standards. She applies this knowledge to help clients validate RF characteristics and address performance issues.

Real-Time Embedded Systems

Dr. Tian advises clients on the design, evaluation, and failure analysis of real-time embedded systems used in communication and networking applications. Her expertise covers time-critical software, high-speed logic design, and the hardware-software partitioning decisions that determine system reliability and performance under demanding operational conditions.

Dr. Tian brings practical insight into the constraints of real-time operating environments, including latency, determinism, and fault tolerance that are often central to disputes involving embedded communication products. This experience is particularly relevant to clients in the telecommunications, defense, and consumer electronics sectors where embedded system behavior is subject to technical scrutiny or regulatory review.

Architecture & Software Evaluation

Dr. Tian conducts independent architecture reviews and software evaluations for clients developing or defending complex communication systems. Her consulting in this area includes system architecture assessment, protocol stack analysis, software partitioning, and the evaluation of design decisions against industry best practices and applicable standards. Dr. Tian has applied these methods across Wi-Fi, satellite, and cable access networks, helping clients understand whether a system was designed and implemented in a manner consistent with its intended requirements, and she has served as a technical expert in intellectual property and product liability matters involving communication system architecture and software design.
