Try it live, with the agent (sample sites only): https://meymandar02--sitetwin-3d.us-east.modal.run/portfolio.html Pick any of the ten sites, open it in 3D and press "Analyse this problem": about a minute each. SiteTwin 3D is an AI site engineer for mobile base stations. Before an operator changes an antenna, someone has to answer: who ends up inside its EMF safety zone, is the rooftop safe, does the busy cell get capacity? Today that takes reports, spreadsheets and site visits, and a school or a hospital next to a site makes it urgent. I'm a radio site engineer in Turkey. During the hackathon I built SiteTwin 3D on top of my private site-file tool: - A portfolio map: every site checked automatically and ranked by urgency. - A 3D twin of each site with the real buildings around it. - EMF safety checks written from scratch to Turkey's BTK regulation (stricter for schools and hospitals, overlapping antennas summed, rooftops at head height), plus capacity from the busy-hour load. - The Expert Operator, an agent on Muse Spark Open: it calls tools on the live twin, tries a dozen options (each one plays on the 3D view and is checked by the twin's own rules), ranks them schools first, applies the chosen one as a simulation and writes the field work order: crew, days, tools, precautions. - Voice (Muse Voice Transcribe) and site photos (Muse Spark 1.3). - A portfolio tour: the operator fixes every urgent site in turn and hands over one combined action plan. Speed: on the East Palo Alto sample, five problems are found and solved in the plan in 35 seconds, with 12 options checked against every rule. Ten sample sites to try, five in Turkey and five next to Meta's Menlo Park campus, each with a different problem (the US samples are checked against Turkey's limits; FCC is not modelled). Nothing changes on a real site: every plan is a simulation, and a field measurement has the last word.
