The better (read: twice as expensive) provider in Germany does that as well and I rarely have a problem even in crowded events (haven't tried at Oktoberfest). To be precise for well-known large events all networks erect temporary towers but inferior ones cheap out on capacity. On the other hand, Oktoberfest has an order of magnitude more visitors than ACL in a very small area. Probably physics will limit what you can do.
