In November, Broadcom, a global leader in wired and wireless communication semiconductors, announced the launch of the first commercial smartphone featuring its M-Stream technology—the Palm Treo® 680. This innovative device marks a significant advancement in mobile phone performance, offering improved signal reception and voice quality without increasing the bill of materials (BOM) or requiring network infrastructure upgrades.
The Treo 680 is the third embedded version of Broadcom’s baseband processor and industry-leading Bluetooth solution in the Palm Treo line, now enhanced with M-Stream technology. This technology significantly enhances voice clarity and extends signal coverage, providing users with a more reliable and high-quality calling experience. It also helps network operators boost their existing network capacity without costly upgrades, making it a win for both users and providers.
“M-Stream technology represents a major milestone for Broadcom,†said Ketan Kamdar, Vice President of Broadcom’s Mobile Division. “It reinforces our position as a market leader in mobile communications and showcases our commitment to delivering cutting-edge solutions that improve user experiences.â€
M-Stream technology addresses common issues like dropped calls and poor signal quality by using an advanced error correction algorithm to restore lost data in incoming voice streams. This enhancement is particularly beneficial in weak signal areas, where it can dramatically improve speech intelligibility and overall call quality. The technology is compatible with both GSM and WCDMA networks and has been shown to increase signal-to-noise ratios by up to 3 dB in GSM environments and 1.5 dB in WCDMA setups.
Moreover, M-Stream complements other signal enhancement technologies, such as Broadcom’s DARP (Downstream Advanced Reception Performance), which helps reduce interference on public channels. When combined, these technologies can achieve up to a 6 dB improvement in signal quality, allowing network operators to expand coverage and support more users efficiently.
In addition to M-Stream, the Treo 680 features Broadcom’s BCM2133 single-chip baseband processor, supporting EDGE, GPRS, and GSM standards. This compact and power-efficient solution enables high-speed data connectivity while keeping costs low, making it ideal for smartphones, PC cards, and embedded modules.
The device also includes the BCM2045 Bluetooth chip, an advanced single-chip solution that offers superior performance in power consumption, size, RF performance, and cost. With support for Bluetooth EDR (Extended Data Rate), the BCM2045 delivers 3 Mbps of bandwidth and a wide range of software profiles, including those for multimedia applications. Its high level of integration reduces peripheral components by nearly 50%, making it a highly efficient and versatile choice for manufacturers.
Overall, the Palm Treo 680 demonstrates how Broadcom’s M-Stream and Bluetooth technologies are pushing the boundaries of mobile communication, delivering better performance, lower costs, and a more seamless user experience.
