2.3. IC Solution
The IC solution for LM-WM860A-R:based on Atheros MB91 chipset
P/N Functionality Description
AR9223 IEEE802.11n MIMO MAC/BB/RF
for 2.4 GHz WLANs
The Atheros AR9223 is a highly integrated single-chip solution
for 2.4GHz 802.11n-ready wireless local area networks (WLANs)
that enable high-performance 2x2 MIMO configurations for
wireless station applications demanding robust link quality and
maximum throughput and range. The AR9223 integrates a
multi-protocol MAC, baseband processor, analog to digital and
digital to analog (ADC/DAC) converters, 2x2 MIMO radio
tranceiver, and PCI interface in an all CMOS device for low
power and small form factor applications.
