Field notes: RF behavior in dense walls and service cores

What we watch when a building isn’t a clean drywall lab.

1 min read

Method, briefly

We treat every site as three layers: air path, structural attenuators, and RF noise from neighboring gear. Floor plans rarely capture all three.

What consistently matters

  • Orientation of service cores relative to where buttons need to live.
  • Presence of metal-clad risers or mirrored lift walls.
  • Legacy 433/868/915 activity from older security or gate gear.

Commissioning takeaway

Start with worst-path buttons during daylight hours, then validate after-hours when noise floors shift. Document the handset used and firmware revision—future-you will thank present-you.

This is a qualitative field memo, not a substitute for spectrum analysis when required.
