Ultra Mobile PC The Ultra-Mobile PC’s (UMPC), Ultra-Mobile Devices (UMD) and Mobile Internet Devices (MID) are witnessing one of the fastest growths in the mobile device market today. These devices provide access to content and information virtually anytime and anywhere in addition to services like e-mail, voice, instant messaging, data sharing, audio/videa playback, gaming, etc. There are new applications and use-case scenarios being added constantly while their size is decreasing and battery life is increasing. To this end, robust and low power wireless connectivity is a primary requirement for these devices. They can be connected to the LAN, directly to the Internet or to another mobile device using Wi-Fi, 3G/4G and Bluetooth. The RS9110-N-11-02 fits in best with these requirements with its small footprint and industry-beating power and performance numbers. It provides an easy-to-integrate SDIO interface and also a Bluetooth coexistence interface for platforms which require Bluetooth connectivity along with Wi-Fi.

The IP camera is a camera that captures and encodes the image data, and transports it across the IP network, so that it can be securely monitored and managed remotely. As WiFi becomes ubiquitous, the IP cameras enabled with WiFi bring the security management to a new dimension through wireless transportation and management. Redpine’s RS9110-N-11-02 provides a flexible and scalable ultra low power 802.11bgn solution for both low-end and bandwidth hungry high-end IP cameras, as it can support 30Mbps application-level throughputs. As this 802.11bgn module is available at the same cost of the existing 802.11bg solutions in the market, it provides a cost-effective solution for WiFi based IP camera.

PMP’s have evolved from offering the basic MP3 playback functionality and are today adopting the latest in multimedia and wireless markets. Future features include playback of streaming High Definition video as well. PMP designers face the challenge of constantly adding new features to their products while keeping the cost low and battery life high. While application and media processors have been able to keep up with the speed and power requirements of these new applications to some extent, the challenge has now moved to providing the same requirements in transferring data from a central server to the portable device. This requires the wireless network connection to be highly robust over a long range. The RS9110-N-11-02 module is the perfect answer for these needs. With a small footprint, which is ideal for portable devices, it provides high speed Wi-Fi connectivity by way of its single-stream 802.11n technology while also operating at ultra-low power levels by implementing state-of-the-art power management techniques.
