A network technician is optimizing the 2.4 GHz wireless network for a small office. Access Point 1 is currently operating on Channel 1. Access Point 2, located in an adjacent hallway, was manually configured to Channel 3, causing users in the overlapping coverage zone to experience severe throughput degradation from adjacent-channel interference. Which channel should Access Point 2 be reconfigured to in order to completely eliminate channel overlap with Access Point 1?
- AChannel 2
- BChannel 4
- Channel 6Answer
- DChannel 5
Answer
Access Point 2 should be reconfigured to Channel 6 to eliminate adjacent-channel interference with Access Point 1.
In the 2.4 GHz wireless spectrum, channels are 20 MHz wide and spaced 5 MHz apart. To prevent adjacent-channel interference, wireless deployments must use non-overlapping channels. The standard non-overlapping channels in the 2.4 GHz band are 1, 6, and 11. Since Access Point 1 is on Channel 1, assigning Channel 6 to Access Point 2 ensures sufficient frequency separation so their signals do not bleed into each other.
