Assisted-GPS (AGPS) in mobile devices allows seamless data communication using 5G millimetre wave (mmW), especially for emergency services
Rohde & Schwarz has announced the verification of Assisted-GPS (AGPS) performance in a commercial mobile device, while simultaneously transferring data using 5G millimetre wave (mmW). This capability is now available with the Rohde & Schwarz TS-LBS Location Based Services test system.
5G NR utilizes frequencies in the FR1 frequency range (<7.125GHz) and in the FR2 mmW frequency range(>24GHz). FR2 creates unique challenges for mobile devices in terms of power consumption and heat. With FR2 becoming more common in mobile devices, the performance of critical services such as emergency calls cannot be allowed to degrade when utilizing the mmW spectrum.
Seamless Test Platform
When used together in the TS-LBS test system, the R&S CMX500 radio communication tester and R&SCMW500 wideband radio communication tester provide a seamless and comprehensive test platform that is capable of testing LTE, 5G NR FR1 and FR2, while the R&S SMBV100B vector signal generator simulates the GPS L1 & L5, GALILEO, GLONASS & BEIDOU satellite constellations for A-GNSS. Other positioning technologies that use barometric pressure sensors, WiFi and/or Bluetooth are also available in the same solution. Legacy technologies like GSM, WCDMA and LTE are all supported using the same hardware.
“The addition of FR2 mmW to our TS-LBS test solution gives customers the latest capabilities needed to continue certifying their mobile devices to evolving 5G standards,” said Bryan Helmick, Rohde & Schwarz. “Customers can easily add 5G to existing LTE TS-LBS systems with the simple addition of an R&S CMX500.FR2 support only requires some hardware on the R&S CMX500 and an R&S CMQ500 mmW shield cube.”
