Coverage and signal
These clauses make coverage a measured property of every vehicle path, taken at the client's antenna with the plant as it runs, not a heat map of an empty building.
A heat map of an empty building does not prove a route works. These clauses ask for coverage measured along every path the vehicles use, from the client's own antenna, with racks full and metal moving, against signal and SNR targets you set from the vehicle maker's requirements.

3.1 Coverage on every vehicle path shall
The wireless system shall provide at least [Minimum signal at the client] dBm signal and [Minimum SNR at the client] dB SNR, as received by the client, along every path [Vehicle or machine] uses, including aisles, lifts, doors, and enclosed structures, and not only in open aisles.1
3.2 Survey from the client's side shall
The survey shall be taken with the vehicle's own radio, or one with the same antenna, at the vehicle's real antenna height and mounting, with the vehicle carrying its tallest load, and not with a laptop on a cart.
3.3 Design for the worst condition shall
Coverage in the [Site or area] shall be designed and validated with racks at full and at empty fill level, finished product staged where it is staged in production, and cranes, doors, and vehicles in their working positions and moving. The signal and SNR targets shall be met at the worse of those conditions.
3.4 Raw measurements, not a heat map alone shall
Survey deliverables shall include the raw measurements for each location, with signal, SNR, data rate, and retries, and shall not rely on a predicted or measured heat map alone. The owner shall keep them as the baseline for later surveys.
3.5 A second path where metal moves should
Where large metal moves through a coverage area, each control client should hear at least two access points from different directions above the signal target, so a single object cannot block every path.
