Wi-Fi 2.4 GHz vs 5 GHz
2.4 GHz Wi-Fi reaches further and through walls better but is slower and more crowded; 5 GHz is faster with less interference but shorter range. Cameras may support only one.
Wi-Fi runs on radio bands. The 2.4 GHz band is the older one: its signals travel further and pass obstacles better, but it has few channels and is shared with Bluetooth, microwaves and every other device. The 5 GHz band offers more channels and higher speeds with less interference, but the signal fades faster with distance and walls. Newer Wi-Fi 6E and 7 equipment adds a 6 GHz band.
For cameras the question is often simpler: which band does your camera support at all?
How it works
A router or hotspot broadcasts on one or both bands. A device joins whichever it supports. Many cameras offer both, but some older or entry-level bodies are 2.4 GHz only, and some restrict 5 GHz channels by region. Phones' hotspots may default to 5 GHz; on recent iPhones, the Personal Hotspot's Maximise Compatibility option switches it to 2.4 GHz.
An example: a camera that can't see the hotspot
A photographer sets the camera to join the phone's hotspot, but the network never appears in the camera's list. The camera only supports 2.4 GHz and the phone was broadcasting on 5 GHz. Turning on Maximise Compatibility fixes it.
Wi-Fi bands and CloudTether
For wireless tethering, CloudTether's help suggests a 2.4 GHz network if your camera doesn't see a 5 GHz one. In a crowded venue, 5 GHz can be steadier if both devices support it and stay close. The band only affects the camera-to-phone link; uploads go over the phone's mobile data or internet connection. If Wi-Fi keeps dropping, a USB cable removes the radio question — in CloudTether's logs USB was about three times faster. See camera won't connect over Wi-Fi.
Picking a band on the day
Use what your camera supports; if it supports both, try 5 GHz for speed in busy venues and 2.4 GHz for range in open spaces.
Tips and common mistakes
- Check the camera's specifications for supported Wi-Fi bands.
- Keep camera and phone close — distance hurts 5 GHz most.
- Name 2.4 and 5 GHz networks differently on a travel router so you know which you joined.
