Access Point, Router, Ethernet Converter and Intelligent NIC Solutions

Ralink AP & router solutions include an 802.11n media access controller (MAC) and baseband, a radio, a powerful MIPS®-based CPU core, a 5-port Fast Ethernet switch and physical layer devices (RT3x5x), Ralink Video Turbine™  technology and various interface options for USB, audio devices and system memory.


Ralink AP & router  solutions (RT3662/RT3883) also incorporate transmit beamforming technology. With beamforming technology, the RT3662/3883 intelligently determines a client’s distance and location, and controls its transmitted power and phase to optimize received power at the client. This enables superior Wi-Fi coverage, interference mitigation, and a more reliable connection.


The RT3662/RT3883 are compatible with the newly added beamforming clauses in the IEEE’s final 802.11n standard. In addition, Ralink implements an implicit beamforming technique that can be used with any client, even if they do not support the IEEE’s beamforming protocols. On the receive side, the RT3662/RT3883 employ the latest digital signal processing algorithms such as Maximal Ratio Combining (MRC), and Maximum Likelihood Detection (MLD) and Adaptive Channel Estimation and Equalization (ACE) to ensure robust reception of packets. Ralink’s patented methodology in ACE allows the system to track changes in the environment and continuously optimizing the receiver for maximum performance.


Ralink Video Turbine™

With the advent of digital video, there has been an explosion of content that has become available, both from the internet and from service providers. Consumers want to know how they can conveniently distribute this content to their computers, TV’s, set-top boxes, and mobile devices. Video Turbine™ by Ralink is the answer. It is a combination of technologies used to provide reliable bandwidth for video transmission and reception over Wi-Fi. Ralink has taken the best standards based quality of service (QoS) technologies like Wi-Fi Multimedia (WMM) and Wi-Fi Multimedia Admission Control (WMM-AC), and combined them with Ralink’s own proprietary rate adaptation algorithms, traffic classifiers and distinct controls for audio and video packets to make reliable video distribution over Wi-Fi a reality.


Unsurpassed Wi-Fi Performance

Ralink’s advanced 3T3R architecture implements true 3 stream 802.11n technology, enabling PHY rates of up to 450 Mbps, the highest performance on the market, to address concurrent delivery of data, voice and HD video throughout the home or office. The RT3883 features a 500 MHz MIPS CPU, Hardware Network Address Translation (NAT), and hardware frame aggregation to speed packets to their destination. Connectivity options include an RGMII interface to connect a Gigabit PHY or switch; a 480 Mbps USB 2.0 interface for storage or CE applications; and a PCI Express interface for dual band concurrent applications. The RT3883 also supports SPI, I2C and PCM interfaces for audio and VoIP applications.
