Understanding 5G Location Technologies and Testing GNSS and Hybrid Positioning

Webinars

In this webinar, Keysight takes a look at the many aspects of satellite and cellular-assisted positioning technologies required for location-aware devices, applications, and services. We discuss requirements across standards bodies and carriers, capabilities needed to assure superior performance and accuracy, the challenges associated with comprehensive testing, and solutions to address these testing challenges.

 

Topics covered:

  • Quick glance at a 5G Network Digital Twin

    • The value of emulation/simulation environments to validate performance of 5G and location services

  • A focus on location technologies at an educational level

    • What is GNSS?

      • Update on GNSS technology, including L1 and L5 bands

      • Different testing approaches

      • GNSS + other sensors

      • Vulnerabilities testing

      • Realistic testing environment

    • What is assisted GNSS?

      • Hybrid technologies

      • 3GPP, FCC and carrier specifications

      • Implications for E911

    • 5G considerations for positioning

 

Summary

 

As we approach 5G, difficulty in navigating new technologies will increase exponentially.

 

  • Increased expectations for flawless, differentiated performance

  • More complex but we still need to deploy in record time

  • Meanwhile, costs are continually under pressure

  • Emulation and simulation of network elements and end-to-end will be critical

 

Benefits of choosing A-GNSS

 

  • Improves acquisition speed (Time to First Fix -TTFF)

    • With fast TTFF, it just takes seconds from user’s push for a position fix

  • Reduces power consumption

    • GPS receiver does not need to decode navigation data

    • Less time looking for satellites

  • Improves signal level (code phase tracking)

    • Around 25dB

  • Allows operation in traditionally challenging GNSS environments

    • Heavy foliage, indoors, urban canyons
