A network technician is optimizing a 2.4 GHz wireless deployment in a corporate warehouse where handheld mobile inventory scanners frequently drop network connections. A site survey reveals that neighboring access points are broadcasting on channels 2, 3, and 4, resulting in severe performance degradation. Which of the following channel configurations should the technician implement on the access points to eliminate wireless channel overlap?
- Reconfigure the access points to use non-overlapping channels 1, 6, and 11.Cevap
- BReassign the access points to adjacent channels 4, 5, and 6 to evenly space out signal frequencies.
- CFilter access point connections by registering each mobile scanner's IMEI in the access point radio settings.
- DConfigure all mobile scanners to use APIPA IP addresses to bypass wireless channel congestion.
Cevap
Reconfigure the access points to use non-overlapping channels 1, 6, and 11.
Configuring 2.4 GHz access points to use channels 1, 6, and 11 prevents adjacent-channel interference. In standard 2.4 GHz Wi-Fi networks, these three channels are the only non-overlapping channel combination available in North America and many standard regulatory domains.
