An increasingly mobile lifestyle is creating demand for tablets that deliver PC performance with high-definition video, 3D gaming, and streaming media applications. Increasing expectations for PC-like functionality and performance in slimmer and sleeker products means chip makers and mobile device designers need to take steps to make these experiences seamless, powerful, and truly 'mobile'. MIMO (multiple-input multiple-output) radio architectures have been used in wireless products, such as notebooks and access points, for much of the last decade. First-generation tablets borrowed Wi-Fi MIMO solutions from smartphones, which use single-antenna combination radios that include Bluetooth and FM in a small, integrated system on chip (SoC). But Wi-Fi performance and reliability issues in these models were widely attributed to the placement of the antenna. Positioned behind the display or on the edge of the product, the single antenna can be obstructed by a flat surface or the user's hand. Enter Marvell's mobile MIMO technology, the industry's first high-performance MIMO Wi-Fi solution featuring two antennas that delivers a true PC-style experience on a mobile device. The inclusion of a second antenna that can be routed away from where the tablet is likely to be placed or handled allows Marvell's mobile MIMO to offer increased link robustness and a considerably diminished likelihood of signal obstruction. It also gives designers an unprecedented level of integration, for higher performance and increased battery life, which is ideal for tablets. Key Features of Marvell Mobile MIMO • Enables a 2x-3x increase in wireless performance (up to 300Mbps) on smaller form factor devices without a significant impact on battery life. This dramatic performance increase enables reliable video streaming, live gaming, and a host of other exciting features on tablets and other mobile devices. • Two antennas offer more design flexibility, considerably diminishing the likelihood of signal obstruction and offering increased link robustness. • Optimized radio co-existence between Wi-Fi, Bluetooth, and FM ensures simultaneous operation and reliable sharing of antennas, thus reducing design costs. • Bluetooth 4.0 Low Energy technology enables new applications centered on home entertainment and automation, security, and personal health. • High-speed, low power I/O interfaces alleviate potential performance bottlenecks that can arise when pairing a MIMO radio with an application processor.
