Tally is very well implemented with the help of WI-FI, the only drawback is the presence of smartphones for all operators and in the case of large distances of WI-FI repellers. I had to put a common antenna (access point from Microtics) and 3 repetitors. despite the high power and coverage area of the Microtics - smart phones have an average radius of up to 100 meters. But even in this case, Microtics covers up to 800-1100 meters of open area, repetitors too on it .... and the stadium by and large can be covered.
