Wifi
Wireless Networking
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 updated with Marvell 88W8780 and became part of the motherboard (no longer on a separate daughterboard).
Hardware
IEEE 802.11b/g wireless network and BlueTooth 2.0 EDR controller chip: Marvell 88W8580 / Marvell 88W8780. See: Bluetooth
The Wi-Fi module uses two internal antennas and allows the PS3 to communicate with access points (normal mode) and Wi-Fi devices like the Sony PSP (AP mode for Remote Play). The Wi-Fi module contains a 16MB ISSI SDRAM memory chip, and a 64KB SPI Serial Interface NOR Macronix flash chip.
