A wireless bridge going to give you a much higher latency time for your setup.
As for latency, the general rule is that you want the minimum latency possible. Any latency in your connection results in losses in mining efficiency. ( possible higher number of stale hares / invalid shares )
With the right setup , fast wireless bridge you still should be ok . You can reduce the latency time to connecting your miners to the closest mining pool server to your location. Probably you not going to get a stable connection with WiFi , like what you are able to archive with wired connection.
Im always suggesting to everyone to use wired connection if its possible
for stability.
