WIRELESS SIMULATION SYSTEMS
Model the network before you touch it.
Trilcomm builds simulation platforms for 5G and 6G radio networks — from a hundred emulated handsets on a test bench, to a digital twin of a live network with an AI optimizer learning inside it.
PRODUCT ONE
5G NR multi-UE Simulator
One hundred handsets, no handsets. The simulator emulates a hundred independent user devices against a live gNodeB and 5G core — so you can load, break and benchmark a network before a single real phone connects to it.
WHERE IT SITS
A complete UE stack, standing in for a hundred devices
The simulator presents itself to the network exactly as real devices would. Trilcomm builds the physical layer; the higher layers come from a stack partner, and the radio runs on commercial software-defined radio hardware.
UE L2/L3
RRC, NAS and bearer handling for every emulated device.
UE PHY
The layer-1 engine — Trilcomm's own design, and the core of the product.
RF
USRP software-defined radio carrying the air interface.
gNodeB
Any vendor's base station under test.
5G Core
Core network or core simulator completing the end-to-end path.
On the radio front end: building a custom RF front end inside the proof-of-concept window was not viable, so the first release runs on off-the-shelf USRP hardware. Purpose-built RF is part of the commercialization phase.
PROOF-OF-CONCEPT RELEASE
What the first release does
Scoped deliberately: enough scale and enough of the standard to run meaningful interoperability and load testing, on hardware a lab already owns.
- SCALE
- 100 UEsEight bearers on each, attached simultaneously.
- STANDARD
- Release 15 SA3GPP standalone deployment mode.
- SPECTRUM
- FR1 · 100 MHzSub-6 GHz, single BWP PRB operation at 30 kHz subcarrier spacing.
- USE CASE
- eMBBEnhanced mobile broadband traffic profiles.
- HARDWARE
- COTSIntel Core-series server plus USRP software-defined radio.
- CONTROL
- Configuration UISet up runs and drive the simulator without scripting.
HOW THE PRODUCT IS BUILT
Two phases, with customer feedback between them
Prove the physical layer and the integrated stack first. Commit to target hardware and a full feature set only once real customers have run it.
PHASE ONE · PROOF OF CONCEPT
Prove it works
- Initial layer-1 release built and demonstrated to customers
- Interoperability testing against multiple third-party base stations for benchmarking
- Integrated full-stack demonstration across L1, L2 and L3
- First round of customer feedback collected
PHASE TWO · COMMERCIALIZATION
Make it a product
- Move onto target hardware, including purpose-built RF design
- Address what came back from the early trials
- Add the advanced feature set
- Ongoing feature development and product support
PLATFORM
What it runs on, and what it is measured against
The simulator is deliberately built on equipment and tools that test labs already standardize on.

PRODUCT TWO
RANOpt AI Sim Platform and Digital Twin
Where the simulator tests one network element, this tests decisions. A digital twin holds a working model of the network; RANOpt AI learns inside that model and proposes what to change. Neither half is much use alone — the twin gives the optimizer somewhere safe to be wrong, and the optimizer gives the twin a reason to exist.
RANOpt AI Sim Platform
An AI-assisted decision platform for the radio access network. Reinforcement learning agents work against RAN KPIs and propose configuration changes, training inside the twin rather than against live traffic. The platform is built to be interrogated: an engineer can see which KPIs a recommendation trades against before accepting it, instead of taking a number from a black box.
- Reinforcement learning agents
- Trained in simulation, not on live traffic
- KPI trade-offs surfaced, not hidden
- Interactive decision interface for engineers
- 5G NR and 6G scenarios
Digital Twin for 5G and 6G networks
A running software replica of a radio network — cells, channels, traffic and user behaviour kept in step with the real thing. Change a parameter on the twin, watch what happens to coverage, capacity and latency, and only then push the change to the network. It is also the environment RANOpt AI trains in, and the bench the rest of the portfolio is validated against.
- Live-network state synchronization
- What-if analysis before deployment
- Coverage, capacity and latency modelling
- Closed-loop interface for optimization
- 5G NR today, 6G candidate waveforms next
ALSO UNDER DEVELOPMENT
Narrower simulators feeding both products
Each of these models one hard part of the radio environment, and feeds its results into the twin.
Non-terrestrial networks
LEO and GEO link emulation with realistic propagation delay, Doppler and handover behaviour for satellite-integrated 5G and 6G.
O-RAN interoperability bench
Open fronthaul and RIC interface testing, so disaggregated components from different vendors can be proven against one another.
Integrated sensing and communication
Joint radar-and-communication waveform modelling for the sensing use cases arriving with 6G.
Reconfigurable surface channels
Channel models for RIS-assisted links, where the propagation environment itself becomes a controllable part of the system.
High-mobility waveforms
Delay-Doppler domain modulation such as OTFS, evaluated under the conditions where conventional OFDM starts to struggle.
PROMOTERS
Four decades of the thing being simulated
Dr Rao S. Yenamandra
PROMOTER
Trilcomm was built on a career spent inside the systems it now models. That career started with India's Department of Telecommunications, in the era of copper and switching, and ran through the wireless generations at Qualcomm, where he served as Vice President of Engineering and worked at the physical layer of the standards that became everyday infrastructure.
The through-line is layer one. Trilcomm's products exist because the hardest part of testing a radio network is faithfully pretending to be one — and that requires knowing what the standard actually does, not just what the specification says.
He now writes and teaches on wireless systems, and is the author of Telecom Memoir: From Wireless 1G to 6G and Beyond.

Dr Gopala Rao Yenamandra
CO-PROMOTER
The academic half of the same discipline. Dr Yenamandra served as Head of the Department of Electronics and Communication Engineering at Andhra University in Andhra Pradesh, where he taught and supervised research across the communication engineering curriculum.
Where Trilcomm's products come out of industry practice, his contribution comes from the other direction — the theory those products are obliged to get right, and the generations of engineers who learned it from him.
He works today as an independent consultant.
