One program. One scene.
Channel, network, and radar, all coherent.

nss is an integrated sensing and communication (ISAC) simulator. An LLM writes a scene program over a closed vocabulary of zones, roles and itineraries; a compiler supplies every quantity from data and builds the venue. From that one scene, the same bodies drive one ray-traced channel, a 5G network, and a radar that samples on the network's own transmissions.

See the column cut the link, and the radar see it coming.

One traveler (UE2) walks through the airport. Around 14.2 s a column cuts her line of sight to AP9, while AP1 stays clear. One slider drives the video, the sensed track, the forecast, and the SNR of both APs.

Every venue is a program you can read.

Hover a card to play the scene; click it to flip and read the program the LLM wrote, with what the compiler made of it. The programs ship with the release, so every scene rebuilds without the LLM.

03Get started

From a prompt to network KPIs.

Install, compile a shipped program, and score a controller. Shipped programs replay without an LLM.
