  • The Rise and Challenges of M2M Applications (PDF, eBook)
    2013 could be the year when machine-to-machine (M2M) communications exceed human-to-human communications for the first time in history, with even more machines connected to the Internet than people. Equipping devices with M2M communications has special requirements, however, depending on the application. It is important to consider these features when thinking not only of the initial design, but also about product longevity - how long the device should operate before needing replacement, geographical coverage, and compatibility with wireless network upgrades, 2G to 3G to 4G. This article discusses 12 specific issues that should be considered when designing devices for M2M applications.

  • u-blox' GNSS and wireless module philosophy (PDF, eBook)
    Focus on compatibility and upgradeability: In today’s electronics industry, particularly for industrial machine-to-machine (M2M) applications such as fleet and asset management systems, product cycles are short, typically 9 months to a year for each product upgrade cycle, with overall product life-span lasting up to 10 years. During this time, designers must continuously improve their products to meet emerging new technologies as well as address regional markets beyond the scope of their original design. This creates design challenges, especially when upgrading the positioning and wireless modem components to address new market requirements such as extended GNSS support, as well as compatibility with multiple mobile network standards. This whitepaper examines some of these issues and recommended solutions.

  • u-blox' Solution for European eCall (PDF)
    With the imminent deployment of European eCall in 2015, development of In-vehicle eCall Systems (IVS) is in full swing. The correct choice of components will have a large affect on time-to-market. Important factors to consider are the possibility to verify IVS designs before eCall is deployed, the ability to support design-in requirements of closely-coupled GPS and GSM subsystems, comprehensive software support, component-level certification of the GSM modem, forward compatibility with future wireless technologies, and the availability of automotive-grade GPS and GSM components in high-volume. This paper examines these requirements.

  • u-blox’ comprehensive approach to multi-GNSS positioning (PDF, eBook, Korean PDF)
    GPS has been around for 30 years, becoming the global defacto standard for navigation and positioning. This situation is rapidly changing. To reduce or eliminate the reliance on the US-based GPS satellite network for both government and civilian navigation and positioning systems, Russia, China and the EU are deploying their own parallel, large-area Global Navigation Satellite Systems (“GNSS”). Japan has also started to deploy its own satellite augmentation designed to improve GPS performance in Japan and areas of Southeast Asia and Oceania. To address this expanding array of new GNSS systems, u-blox has introduced low-power, multi-GNSS capability into its newest generation satellite positioning platform u-blox 7.
