CONTEXT: We are searching for WIFI AP able to broadcast UDP stream on a maximum number of connections: 10, 30, 50, 100, 150, 200 (guess the WIFI point is different in term of price and technology according the number of possible clients). The goal is to use a WIFI AP as radio antenna to broadcast an audio stream (48kHz Stereo 16bit < 3 Mbps).
QUESTION: What technology / criteria must be considered in modern WIFI point to be able 1- to broadcast 3 Mbps stream 2- to manage a big number of connections (50 to 250).
Thanks by advance for your advises, experience feedback. (does it change something if the broadcast stream is 500 Kbps instead of 3 Mbps)
