The PS3 contains two wireless technologies, Wi-Fi | The PS3 contains two wireless technologies, Wi-Fi 802.11b/g and Bluetooth 2.0. It is not possible for both to be used at the same time, so the PS3 alternates between Wi-Fi and Bluetooth communication at a very fast frequency using time division multiplexing. Both wireless capabilities are powered by the Marvell 88W8580 chip. In [[SKU Models]] CECHL and later, this wireless module became part of the motherboard, and is no longer on a separate daughterboard. | ||
