    Hello Mark,
    usually beacons are not in connected state as these are only advertising on the three advertisement channels (ch37(2402MHz), ch38(2426MHz), ch39 (2480 MHz)) at defined intervals. You will need to set up a spreadsheet or statistical calculations to find a probability for collisions depending on number of devices, defined interval, link budget between devices, etc. This can become quite complicated. The best would be to do some field testing an a controlled environment to get realistic numbers.

    Please read more detailed info in the Bluetooth® Low Energy Beacons App note:
