  "description": "A small shared office: three desks along the window wall, a meeting table, a storage cupboard and a sofa. SCENE data, typed in, not sensed. The four walls carry different materials on purpose — a concrete structural wall, an exterior brick wall and two drywall partitions — because wall material is the one scene property that changes the radio physics, and a viewer should be able to see that it is a DEFINED property and not something the radio worked out. The entry door is 0.9 m, which is an office door; an ordinary interior door is 0.8 m.",
