We may have "priority", but in reality it is just on paper.
Getting the users already there to shut down or move would pretty much be
You should look at another band besides 2.4

Subject: [Ham-80211] Providing Long-range Wifi

I am working with our local EMA to be able to provide wifi internet access
at disaster scenes and special events in our county.  I have read articles
where people have achieved long distances over line of sight paths. But in
our case, line of sight may not always be possible, due to rolling terrain,
trees, buildings etc.  I have a 29 db gain dish on my tower at 90 feet. The
idea is to aim it at the required location, and use a portable gain antenna
at the other end (maybe 24 db at 40 feet) for a point-to-point link, and
then relaunch wifi locally for on-the scene laptops etc.  We plan to
experiment with this as soon as we have the necessary equipment on hand.

The thought is to use wifi channel 1 or 2, as that is where hams are
priority users in the frequency allocations.  We would like to use as much
power as possible, but the cost of commercial units may limit that to a watt
or so.  25 miles would be adequate.

Also wondering how hams typically send their callsign ID for wifi

Suggestions and comments would be most welcome.
