Ubiquiti M222G Users Manual
2X2-2G Single-Band
MIMO 802.11 b/g/n
WLAN Specification
System Overview
General Descriptions
The 2X2-2G with MTK solution is a highly integrated Wi-Fi single chip which supports 300 Mbps
PHY rate. It fully complies with IEEE 802.11n and IEEE 802.11 b/g standards, offering feature-rich
wireless connectivity at high standards, and delivering reliable, cost-effective throughput from an extended distance.
Optimized RF architecture and baseband algorithms provide superb performance and low power
consumption. Intelligent MAC design deploys a high efficient DMA engine and hardware data
processing accelerators which offloads the host processor.
The 2X2-2G is designed to support standard based features in the areas of security, quality of
service and international regulations, giving end users the greatest performance any time and in any
circumstance.
