Figure 1-9. MPC8313E as a WLAN Access Point
Current systems are being designed for IEEE Std. 802.11b® and 802.11a/g® as well as combo radios. The
WiFi chipsets are on PCI in current systems. With the migration to IEEE 802.11n standard and the
increased management features required by the IT community, the need for higher performance is
growing.
These WLAN access points (WAPs) require low power and are usually powered exclusively by Power
over Ethernet (POE). Each Ethernet line can power about 12 W. With the power the radios draw and the
rest of the board this usually only leaves < 2.5 W for the embedded processor.
Integrated SGMII makes it possible to connect to low power Gigabit Ethernet PHYs. Power is a main
consideration for WAPs deployed throughout the premise. Power is drawn from the AC outlet in the wall
or power over Ethernet. Having an SGMII interface on the Gigabit Ethernet PHYs enables low overall
power consumption. The MPC8313E also has superior PCI to memory performance.
