Sensing and signal processing
Algorithms and calibration for wireless sensing and high-precision positioning, plus structured output of sensing results.
ABOUT US
Three product lines, from one idea about access.
JANUS AI LINK is based in Shanghai. We connect three things into one line: sensing the physical world, opening the data path into compute, and closing the loop of intelligence inside an industry. These are not three businesses bolted together — they are three stages of the same technical judgement.
Why we are called Juheng Zhilian
The name comes from Janus, the Roman god of gates, passages and beginnings — the deity the Romans called "the beginning of all gods". The English word January comes from the same root.
- "Juheng" means measure and balance — verifiable, quantifiable standards come first for us
- "Zhilian" points to intelligent connection — making devices, and devices with platforms, genuinely connected
- The door is the threshold of space: it maps to the high-speed data interface that carries physical-world data into compute
- The two faces are the threshold of time: one looking back at accumulated data, one looking ahead at trends. Interlocked, they form ∞
- The beginning means continuous iteration: every outcome flows back as the starting point of the next cycle, so the system sharpens with use
Team background
The team is our most substantial asset — the capability built during the previous chapter of our work carries directly into the three product lines we run now.
- Our founder is an IEEE Senior Member with a doctorate from Xidian University (jointly trained with UC San Diego), and previously served as Research Director and department head at Bell Labs (Nokia Bell Labs) China
- Long-standing original research in wireless communication and integrated sensing and communication (ISAC), including leading national-level and Shanghai municipal key R&D programmes, and building a narrowband high-precision positioning system from zero to one with successful commercial rollout
- In 2019, while at Bell Labs China, the team completed a full scenario demonstration of camera-free security for an open office — using RF sensing to recognise activity and gestures, and wireless positioning to determine authorised zones
- Co-founders and core team members come from Bell Labs, NVIDIA and a leading domestic telecom operator, covering SerDes high-speed interfaces, communication baseband, robot control algorithms and large-model system architecture
- The team has delivered on site in asset-heavy industries, including the rollout of a complex robot inspection project in the power sector
How the team is built
Small — but the three product lines are covered by the same team, so there is no gap where one group designs the solution and another turns up on site.
High-speed interface and hardware
Design and validation across FPGA, SerDes, board-level and interface work, and adapting the path into GPU platforms.
Platform and algorithms
Ontology modelling, state fusion, the world model and the agent execution layer, plus industry algorithms such as defect recognition.
Delivery and implementation
Site survey, deployment and calibration, report delivery, and operations handover. This is the part that shapes how the customer ultimately feels about the project.
Our history
We are young, so this list is short — but every entry actually happened.
-
Founded in Shanghai
Settled on AI capability plus integrated hardware/software development as the core direction, progressively converging on three lines: sensing and communication, high-speed data interfaces, and the industry AI platform.
-
Brand and technical system established
Completed the product visual handbook and the mark system, giving us one consistent visual and verbal standard — and fixing the correspondence between the three brand ideas and the three product lines.
-
Website and product structure published
Launched the company website and published each product line together with its maturity positioning, stating our boundaries up front so partners can judge for themselves.
-
First closed loop in one scenario
Moving the first industry scenario to a complete closed loop, to produce a publishable technical case and a delivery process template. Real case data will be added to this page.
Principles we work by
A young team has no brand history to lean on, only the way it works. These three are our defaults.
State the boundaries first
What we can do, what we can't, and what we'd advise against doing now — all said before any commitment. Winning a signature with wording that can't be accepted against only ends badly for both sides.
Never trade an unverified number for attention
Our three product lines are at different stages of maturity, and we label each one. Performance figures are published once there is measured evidence — not before.
Validate in small steps, surface risk early
Prove critical assumptions with a minimum prototype. Better to overturn something early than to let problems accumulate until acceptance.
