OVERVIEW OF THE RALINK AP DEMO BOARD

3.1 RT2880
The RT2880 SOC combines Ralink's 802.11n draft compliant 2T3R MAC/BBP, a high
performance 266-MHz MIPS4KEc CPU core, a Gigabit Ethernet MAC and a PCI host/device, to
enable a multitude of high performance, cost-effective 802.11n applications. The RT2880 has
two RF companion chips: The RT2820, for 2.4G-band operation; and the RT2850, for dual band
2.4G or 5G operations. In addition to traditional AP/router applications, the chipset can be
implemented as a WLAN "intelligent" NIC, drastically reducing the load on the host SOC, such
as DSL/Cable or Multimedia Applications processors. Users can treat the WLAN iNIC as a
simple Ethernet device for easy porting and guaranteed 802.11n WLAN performance without
the need to upgrade to an expensive host SOC.
