A network engineer is troubleshooting persistent connection drops and low throughput reported by wireless barcode scanners in a high-density logistics warehouse. A site survey reveals that neighboring 2.4 GHz access points (APs) are currently assigned to channels 2, 4, and 6, resulting in significant adjacent channel interference. Furthermore, large metal storage racks are generating severe multipath distortion in central aisles. Which of the following remediation steps should the engineer implement to resolve these signal and connectivity issues? (Select TWO.)
- Reassign the 2.4 GHz AP channel plan to exclusively use non-overlapping channels 1, 6, and 11.Answer
- Reposition access points and deploy directional patch antennas directed down narrow aisles to mitigate multipath reflection.Answer
- CEnable 40 MHz channel bonding across all 2.4 GHz access points to increase overall signal penetration and bandwidth.
- DConfigure IP helper addresses on the warehouse switch interfaces to prevent wireless frame loss.
Answer
The network engineer should reassign the 2.4 GHz channel plan to use non-overlapping channels (1, 6, and 11) and reposition APs using directional patch antennas to control multipath reflection.
To resolve adjacent channel interference in 2.4 GHz deployments, access points must be configured using the non-overlapping channel set (channels 1, 6, and 11). Additionally, using directional antennas in environments with high physical reflection (such as metal warehouse shelving) focuses signal propagation and minimizes multipath delay spread.
