With our DNA timing systems, one gate will be assigned the task of becoming the WIFI access point (AP) for the entire system, at connection. This can be seen by the small wifi symbol above the gate that has been assigned this task.
The Wifi system used in our DNA systems is quite strong, and a range of 200m between any other gate (on a tripod) and the AP gate is usual. You might also note when setting up a test that the SYNCRO app will do its best to avoid using a ground based gate as an AP, simply because having any AP close to the ground is inefficient and performs poorly.
The iOS devices have lower performing Wifi systems, and a maximum distance of say, 30m between iPad and te AP gate should be observed to to ensure good data communications.
