Speed and coverage
CMH WiFi delivers fast speeds on the CMH Public Wi-Fi network. CMH WiFi delivers fast speeds suitable for video calls, streaming, and large downloads — even during busy travel periods. Coverage extends throughout the terminal areas and concourses — you generally do not need to reconnect as you move through the airport.
Charging stations
Blue-lit "power tower" charging stations are placed throughout the gate areas in all three concourses, in addition to outlets built into much of the gate seating. Most major US airports — including CMH — provide a mix of USB-A, USB-C, and standard 120 V outlets at gate seating. Bring your own cable; cables are not supplied at charging kiosks.
Pro Tip
CMH is regularly cited as having some of the fastest airport WiFi speeds in the US, and because each of the three concourses sits behind its own security checkpoint, the free network works on both the landside (pre-security) and airside (post-security) sides — useful for checking hotel shuttle numbers before you clear the checkpoint.
