Ralink First to Offer Per-Packet Antenna Diversity Technology in World’s Smallest and Most Integrated 802.11n Wi-Fi Router-on-a-Chip

Ralink Technology Corporation, a leading developer of high performance wired and wireless networking solutions, today announced the world’s first 802.11n router-on-a-chip to include per-packet antenna diversity technology. With MIPS CPU, 5 port 10/100 Ethernet MAC/PHY, PMU, radio, baseband and power amplifiers all contained on a single die, Ralink’s new RT5350 delivers the high performance, smaller size and attractive pricing required for integration into today’s high volume router, broadband connectivity, and consumer electronics products

The RT5350 router-on-a-chip includes an 802.11n media access controller (MAC) and baseband, a 2.4GHz radio and FEM, a 360 MHz MIPS® 24K™ CPU core, and a 5-port 10/100 Ethernet MAC/PHY. The RT5350 requires fewer components and includes almost everything needed to build an AP router from a single chip. The embedded chip level per-packet antenna diversity function enhances load balance and coverage. These results in almost 40 percent faster WLAN throughput over range compared to conventional 1x1 single antenna competing solutions in a multiple-client environment. The USB port can be configured to access external storage for Digital Home applications. In addition, the RT5350 has multiple hardware interfaces (SPI/PCM/I2S/I2C/UART/GDMA) to enable interoperability with many possible applications. Moreover, it features a configurable boot clock rate to prevent 3G, LTE frequency interference.
