Bluetooth

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 models CECHL and later, this wireless module became part of the motherboard, and is no longer on a separate daughterboard.

Hardware

IEEE 802.11b/g wireless network and BlueTooth 2.0 EDR controller chip: Marvell 88W8580

The Bluetooth in the PS3 supports a maximum of eight devices concurrently. With the PS3 console using up one master slot, it leaves seven empty slots for connecting with Bluetooth devices (like Sixaxis and Dualshock3 controllers). The Bluetooth is version 2.0 + EDR (Enhanced Data Rate), supporting a maximum of 2.1 megabits per second data transfer rate. The Bluetooth controller contains 1MB of NOR flash memory using a Spansion chip and another 1MB of NOR flash memory using a SST chip.
