Handheld scanners in a warehouse support 2.4 GHz only. The new capacity WLAN is 5 GHz only, and the scanners never see it. What does the design still need for those scanners?
Select an answer to reveal the explanation.
Short Explanation
The scanners can only listen to one band, and you built the other one. They need a 2.4 GHz service. A wider 5 GHz channel does not grow a radio the scanner does not have.
Full Explanation
Device capability sets the band. These scanners are 2.4 GHz only, so a 5 GHz-only WLAN is invisible to them no matter how much capacity it has. The design still needs a 2.4 GHz service for those scanners. A wider 5 GHz channel does not let a 2.4 GHz radio tune to 5 GHz. A hidden SSID does not add a band the hardware lacks. The beacon interval does not move a WLAN from 5 GHz to 2.4 GHz. Band is a radio and a WLAN setting, not a timer. The scanners are 2.4 GHz only. A capacity design that offers only 5 GHz leaves them with no BSS. Keep a 2.4 GHz service for those devices. Check one live client after the change and do not retune the rest of the floor until that client matches the result you expected. Exam caveat: keeping 2.4 GHz for the scanners does not mean every employee phone should be steered there. Give the scanners a place to join and keep the capacity WLAN for clients that can use 5 GHz. Operational check: advertise 2.4 GHz for the scanner WLAN and confirm a scanner associates while a 5 GHz phone can still use the capacity WLAN.
