Keysight Accelerates Implementation of LBS in Smartphones with Recent GCF Validation - Inside GNSS

Together, 5G NR and GNSS marque assisted GNSS (A-GNSS), enabling mobile telephone vendors to verify that designs comply to the latest 3GPP specifications that enactment close determination positioning for sectors similar wellness care, roadworthy and aerial transportation, exigency and rescue services, nationalist safety, and homeland security. Precise positioning services besides marque it imaginable to present personalized services that enactment entertainment, hospitality and retail applications.

“A-GNSS allows a GNSS receiver successful the 5G smartphone to get info from web resources to assistance successful outer location,” Keysight General Manager Muthu Kumaran said. “It is useful, particularly erstwhile the receiver is successful a determination wherever it is hard for a outer awesome to penetrate. The situation is satellites person a precise debased awesome level due to the fact that they are acold successful space, truthful GNSS receiver show is crucial. Industry certification becomes important to warrant its performance, according to the standard.”

Achieving validation

The support process required Keysight to instrumentality the 3GPP defined trial successful its E7515B UXM 5G Wireless Test Platform, a compact signaling trial level with multiformat stack support, affluent processing power, and abundant RF resources for emulating assorted mobility scenarios successful a 5G web arsenic good arsenic a recommended GNSS emulator to present the LBS trial case. The trial lawsuit is validated by capturing walk logs from 2 antithetic devices and submitting them to an autarkic validation enactment to cheque specification compliance, Kumaran said. The GCF conformance statement radical (CAG) gathering #72 confirmed the validation of the trial lawsuit successful October.

The trial lawsuit was supported by Keysight’s S8705A RF/RRM DVT and Conformance Toolset. The toolset provides entree to a wide scope of vigor frequency, vigor assets absorption (RRM), and improvement validation trial (DVT) trial cases utilized to verify 5G NR designs successful some non-standalone (NSA) and standalone (SA) deployment modes.

“The S8705A toolset supports the widest validated sum for 5G NR trial cases including TRx, Demod, RRM, Data Throughput, and A-GNSS, enabling a idiosyncratic to bash pre-testing and conformance investigating of their products earlier marketplace rotation out,” Kumaran said. “The toolset besides allows flexible parametrization of the trial to benchmark the instrumentality and trial it beyond the limits established by conformance regimes.”

Why LBS

A location-based work is immoderate exertion that depends connected real-time determination tracking to function, Kumaran said.

“The exertion perpetually identifies the user’s carnal and geographical location, which is past utilized to execute services and functions,” Kumaran said. “The main exertion is GNSS (GPS, Galileo, Glonas, Beidou), but cellular technology, utilizing basal presumption triangulation, tin besides beryllium combined with GNSS to summation accuracy of location.”

LBS trial cases similar this 1 let users to verify sensitivity, accuracy and dynamic scope successful mobile phones that usage outer constellations to place precise geographic location.

A assortment of industries tin payment from LBS, including travel. Rideshare apps america LBS to function, portion roadside assistance companies often supply an app that makes it imaginable to way someone’s nonstop determination aft a car accident, for example, Kumaran said.

Public information is different country wherever LBS plays a captious role, Kumaran said, by identifying the carnal locations of exigency callers.

“When callers to Public Safety Answering Points (PSAPs) can’t accurately supply their location, measures are needed to dispatch archetypal responders to the close place,” Kumaran said. “Similarly, successful a wide exigency event, the quality to nonstop intelligent messages lone to those users wrong a well-defined geographic country tin marque authoritative effect measures much effective. Both these scenarios beryllium connected the accuracy, speed, and reliability of automated LBS to assistance public-safety unit find and assistance those successful need.”

What’s next

Keysight plans to summation trial lawsuit sum for LBS either for Assisted Galileo, Assisted GPS oregon Assisted Beidou, Kumaran said, and volition enactment to get the archetypal GCF validation for LBS trial cases for the Glonass planetary navigation outer strategy arsenic soon arsenic devices are available.

Once that extremity is met, the institution volition absorption connected validation of positioning enhancements successful Rel-16, enabling close positioning with GNSS assisted by cellular networks, not lone outdoors with outer visibility, but besides indoors.

“For that, devices volition request to enactment a caller downlink-based positioning method to conscionable the positioning accuracy demanded successful these caller scenarios,” Kumaran said. “This caller method is based connected a caller positioning notation awesome (PRS) that enables a much precise clip of accomplishment (ToA) estimation. The UE volition study PRSs received from aggregate basal stations and this accusation volition let the close determination of its position.”

Keysight volition proceed providing the enactment of positioning enhancements tests to beryllium included successful Rel-17 with a absorption connected Industrial Internet of Things scenarios, Kumaran said, which volition necessitate higher accuracy and little latency.

“New applications request caller scenarios wherever it is required to cognize the instrumentality presumption faster and with much and much accuracy,” Kumaran said. “This is achieved combining planetary navigation outer strategy (GNSS) and cellular technologies.”
