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 (note, see:Marvell-WiFi-Bluetooth-Coexistence.pdf). Both wireless capabilities are powered by the Marvell 88W8580 chip, used on both daughterboards CWI-001 (CECHA, CECHB, CECHC) and UWB-001 (CECHH, CECHJ, CECHK). 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.
