# Wi-Fi Channel Overlap Planner Plan 2.4, 5, and 6 GHz Wi-Fi channels from measured AP channels, widths, and RSSI, with overlap, DFS, and PSC warnings. > Canonical page: https://elysiatools.com/en/tools/wifi-channel-overlap-planner - **Category:** Network - **Keywords:** Wi-Fi channels, channel overlap, DFS, 6 GHz PSC, wireless planning ## Overview Enter one AP per line as name | band | channel | width MHz | RSSI | optional x | optional y. Recommendations use supplied RF observations and standard channel centers; physical placement advice is shown only when coordinates are present. ## Inputs - **Access points** (textarea): Living room | 2.4 | 1 | 40 | -42 Office | 2.4 | 6 | 20 | -58 Main 5G | 5 | 100 | 80 | -55 - **Regulatory region** (select) ## When to use - When setting up multiple access points in a home or office and experiencing slow speeds or dropped connections due to interference. - When configuring 5 GHz or 6 GHz networks and needing to verify DFS channel usage or PSC compliance for faster client discovery. - When auditing an existing wireless deployment to map channel overlaps and optimize channel width allocations. ## How it works - Input your access point details line-by-line, specifying the name, band (2.4, 5, or 6 GHz), channel, channel width in MHz, and RSSI, with optional X and Y coordinates. - Select your regulatory region (US or EU) to ensure compliance with local channel allocations and DFS rules. - Analyze the generated HTML report to view band-specific recommendations, overlap pairs, DFS/PSC warnings, and physical placement advice if coordinates were provided. ## Use cases - Optimizing a multi-AP home network to eliminate 2.4 GHz channel overlap and configure non-overlapping 5 GHz channels. - Planning a high-density office Wi-Fi deployment using 6 GHz PSC channels to ensure fast client roaming and minimal interference. - Troubleshooting signal degradation in a warehouse by mapping AP coordinates and RSSI values to identify physical placement issues. ## Frequently asked questions ### What is a DFS warning? It indicates that the access point is operating on a Dynamic Frequency Selection channel, which may be subject to radar interference and temporary channel changes. ### What does the 6 GHz PSC warning mean? It flags whether your 6 GHz access point is using a Preferred Scanning Channel, which is critical for client devices to discover the network quickly. ### How do I include physical placement in the analysis? Add optional X and Y coordinates at the end of each access point line (e.g., AP Name | 5 | 36 | 80 | -50 | 10 | 15) to enable physical distance and placement advice. ### Why does channel width matter for overlap? Wider channels (like 40, 80, or 160 MHz) span multiple standard channels, increasing the likelihood of overlapping with neighboring access points. ### Can I plan networks for both US and Europe? Yes, you can select either the US or EU regulatory region to apply the correct channel limits and DFS rules for your location. ## Related tools - [NB-IoT LTE-M Cat-M1 CoAP LwM2M Cellular IoT Packet Analyzer](https://elysiatools.com/en/tools/nb-iot-lte-m-cat-m1-coap-lwm2m-cellular-iot-packet-analyzer): Decode hex captures from cellular IoT devices: CoAP headers/options (block-wise, Observe), LwM2M TLV object trees with registry names, SMS-DELIVER UDH port addressing unwrapping CoAP-over-SMS, link-format registrations and DTLS record summaries. - [DNSSEC Chain & RDAP Trust Auditor](https://elysiatools.com/en/tools/whois-rdap-dnssec-chain-validator-and-iana-bootstrap-trust-auditor): Audit a domain end to end: IANA RDAP bootstrap referral, registry/registrar WHOIS data, and the DNSSEC chain of trust from the root KSK through the TLD DS to the apex DNSKEY — with DS digest verification and RRSIG expiry flags. - [CIDR Calculator](https://elysiatools.com/en/tools/cidr-calculator): Calculate network information from CIDR notation.
