Using wireless sensors with nRF54L15, the sensors do not need to be connected, only broadcast a small amount of information. There will be 50-60 thousand nodes, and they are very dense. Will this cause channel congestion? Will the number of devices simultaneously in broadcast mode differ when using 1M PHY, 2M PHY, CODEC PHY? If it is not possible to support so many broadcasts at the same time, what solutions are available to solve this problem?
