Long range omni-directional WiFi antenna?

I do event photography here and there, and when I do I normally bring a dye-sub printer which lets me print photos directly from the camera by FTPing the images to the WCM print server (which runs on a Raspberry Pi). This lets me print photos for the attendees that they can leave with.

I’d like to try the same thing at a couple sporting events for the local high school. I’ve never had problems with the standard “rubber duck” antenna at event venues, but obviously football fields are much larger than the typical event venue.

How much longer of a range could I theoretically get assuming I had nearly unimpeded line-of-sight from the camera to the antenna?

Are there any antennas that would be well suited for this?

Interesting problem.
Since I have no clue about this, I am just boosting your thread by being here :slight_smile:

Range for open spaces is pretty good, but really depends on RF environment structure etc.

You will eventually run out of range on the camera side since it can only put out so much power.

Wouldn’t range/usability be also limited by the expected higher number of mobile devices clogging the wifi frequencies?

Depends on channels uesed too, so many variables to be honest.

Almost want to say like cloud vpn and two cell devices
