A municipal warehouse WLAN must support an older handheld scanner that needs roughly −67 dBm and solid SNR. Which client should set the RF targets?
Select an answer to reveal the explanation.
Short Explanation
Design for the cranky old scanner, not the shiny laptop that hears everything. If the least-capable critical device is happy at −67 dBm with enough SNR, the newer radios will be fine. Betting on future upgrades during predictive design is how warehouses stay broken.
Full Explanation
RF design targets for primary applications should be set by the least-capable critical client class, commonly near −67 dBm with adequate SNR for scanners and similar devices. Designing only to high-end laptops underestimates attenuation and antenna limitations of warehouse handhelds. Assuming automatic upgrades is not a requirements method.
