  • Telit unveils 450-Mbps LTE-advanced automotive-grade module

    Telit has introduced the LE940A9 smart module, an automotive-grade module designed to support LTE Advanced Category 9 (Cat 9) networks.

    The series offers three multi-band, multi-mode variants — including voice-over-LTE (VoLTE) — and is optimized for automobile manufacturers to deploy next-generation connected-car technology in world markets.

    The LE940A9 is the latest addition to Telit’s xE940 family of automotive-grade modules. According to Telit, it delivers 450 Mbps download and 50 Mbps upload speeds with extremely low latency and advanced security, enabling the next wave of automobile industry’s applications and services which also serve as a springboard for autonomous driving.

    “Digital transformation is driving the evolution of the connected car with major improvements in driver safety, new revenue streams, and an immersive connected experience,” Telit said in a press release. “With government safety mandates around the globe, added advancements in the connected world, there is greater demand for more value-add services and feature-rich in-vehicle applications.

    The xE940A9 40×40 mm LGA form factor nests with the 34x40mm Telit xE920 automotive module family, offering flexibility for the OEM or tier-one integrator.

    “From commercial and consumer telematics services, to autonomous driving and driver assistance features, along with a host of other applications dependent on remote software updates, including infotainment; secure, wired broadband-like speed is now a requirement. The evolution to high-speed wireless connectivity is only possible if powered by LTE Advanced, with little to no lag time, for the applications to work.”

    The LE940A9 powers the entire connected-car platform, supporting current needs while including advanced features that enable future integration of upcoming value-added, telematics and managed services.

    The module can run in-vehicle applications inside a secure processing environment from the built-in application processor, storage and memory. Automotive application programs can run entirely and securely on the module itself, protected by advanced cyber-security capabilities.

    “In addition to serving as a significant advancement for the connected car industry, the LE940A9 series is a powerful testament to Telit’s continued technology leadership enabling the future of the connected car worldwide,” said Yossi Moscovitz, CEO of Telit Automotive Solutions. “Not only does the LE940A9 enable unprecedented applications with the speed and low latency of Cat 9 of the multi-mode variants, it also simplifies integration and reduces costs that help accelerate the development of our OEM partners’ global roadmaps.”

    Spirent Enhances Location Availability for VoLTE E911 Calls Indoors

    Spirent Communications has announced major enhancements that will help improve location accuracy for E911 calls indoors. The additional test capabilities on Spirent’s 8100 Location Technology Solution (LTS) enable operators to deliver optimal location performance to support VoLTE E911 calling and to understand how LTE positioning technologies such as OTDOA can help meet the recently proposed Federal Communications Commission (FCC) regulations for E911 indoors.

    OTDOA accuracy is 50 to 200 meters.

    LTE brings a promise of improved location accuracy with new positioning technologies and their integration using hybrid techniques. Although established technologies such as A-GNSS (A-GPS and A-GLONASS) provides excellent performance in environments with a clear view of the sky, performance is often poor indoors, where detection of satellite signals is limited. In LTE, current standards support Observed Time Difference of Arrival (OTDOA), an advanced cellular positioning technology that can augment A-GNSS and provide a more accurate location fix for indoor scenarios.

    With large-scale VoLTE rollouts imminent, leading operators are confronted with the need for extensive and complex testing of LTE positioning technologies to ensure VoLTE E911 works well from day one. Additionally, the FCC, whose current E911 regulations apply only to outdoor environments, has proposed stringent indoor requirements as a response to increased mobile usage for emergency calls and lack of accurate positioning information on calls that originate indoors.

    “Roughly 70 percent of 911 calls are placed from wireless phones and a majority of these calls originate indoors, so there is a real urgency in providing better location accuracy for mobile users, wherever they are calling from,” said Nigel Wright, vice president at Spirent Communications. “Spirent is currently working with all the key industry players to evaluate OTDOA and its integration with other positioning technologies, and to enable operators to meet the location requirements for VoLTE E911 and the evolving FCC requirements.”

    Spirent 8100 LTS has won widespread acceptance as the leading platform for location testing in the wireless industry, and with this latest capability is now able to support OTDOA Position Calculation Function (PCF). Minimum performance testing for OTDOA looks only at the raw measurements from the device, whereas use of OTDOA PCF enables full verification of a device’s position accuracy performance. Recognizing its importance, leading carriers have established their own OTDOA positioning performance requirements beyond bare minimum standards. Ensuring that devices fully meet these requirements as well as the evolving FCC regulations for E911 requires comprehensive testing.
