5G and multi-mode device testing

• Addresses 5G NR in both non-standalone (NSA) and standalone (SA) modes, 4G LTE, WCDMA, GSM, CDMA, Wi-Fi, Cat M1, and Bluetooth Low Energy (BLE)
• Supports 3GPP Rel 15 and Rel 16 location features, including Emergency Fallback, Voice over New Radio (VoNR), downlink/uplink OTDOA, angle of arrival (AoA), and multi-round trip time (RTT)
• Tests 4G/5G coexistence to evaluate intermodulation and harmonic interference effects on location performance

Conformance and operator acceptance

• Validated for GCF, PTCRB, CTIA, CCSA, and OMA test specifications
• Supports VoLTE E911 functional tests, E911 calling over Wi-Fi, and barometric pressure z-axis testing for FCC and carrier requirements

Conducted and over-the-air (OTA) testing

• Controls conducted-mode and radiated OTA testing from a single user interface
• Integrates with anechoic test chambers; compliant with current LTE OTA CTIA test requirements

Hybrid indoor positioning

• Emulates up to 32 Wi-Fi access points via the SR5750 multi-access point (AP) instrument for Wi-Fi protocol and performance tests
• Supports indoor positioning methods including Wi-Fi, Bluetooth, and barometric pressure via LPPe

Productivity

• Parallel device testing executes test cases on two devices simultaneously to reduce overall test time
• A-GNSS record and playback capability brings field testing conditions into the lab with controlled, repeatable methodology

The 8100 5G Mobile Device Test System provides automated, scalable performance testing for 5G mobile devices across voice, data, video, and location technologies on a single expandable platform.

Test coverage and standards

• Supports frequency division duplex (FDD) and time division duplex (TDD) NR, FDD and TDD LTE (Option 3x), and standalone 5G (Option 2)
• Delivers 256 quadrature amplitude modulation (QAM) on both uplink and downlink with 4 downlink and 2 uplink multiple-input, multiple-output (MIMO) streams
• Provides standards-based conformance testing aligned to 3rd Generation Partnership Project (3GPP), Global Certification Forum (GCF), and PCS Type Certification Review Board (PTCRB) requirements
• Offers comprehensive assisted global navigation satellite system (A-GNSS) location testing across GPS, GLONASS, BeiDou, Galileo, Quasi-Zenith Satellite System (QZSS), and Navigation with Indian Constellation (NAVIC) constellations with multiple frequencies

Automation and analysis

• Runs fully automated tests with pre-configured, customizable test packs based on proven methodologies
• Includes user interface (UI)-based Development Library tools for rapid custom test creation, editing, and execution
• Provides integrated results reporting and analysis for device benchmarking and issue debug

Lab simulation and scalability

• Recreates real-world radio frequency (RF) conditions in the lab with integrated fading and additive white Gaussian noise (AWGN)
• Validates 5G devices on private networks with close-to-live network emulation — from RF environments to end-to-end application validation
• Scales from initial test needs to additional test areas on the same platform as requirements evolve

The A-GNSS OTA test solution delivers automated, radiated GNSS performance testing for mobile devices across GSM, UMTS, CDMA, LTE, and 5G NR networks.

Certification and standards coverage

• Fully supports CTIA's standalone and assisted GNSS OTA Test Plan v9.0, including A-GPS L1+L5, A-GPS L5 only, A-Galileo E1, A-Galileo E5a, and 5G NR non-standalone/standalone (NSA/SA) and 5G RedCap requirements
• Supports China Communications Standards Association (CCSA) OTA requirements for A-BeiDou, standalone BeiDou, GPS+BeiDou, BeiDou only, and BeiDou prefer with signals B1i, B1c, B2a, B2i, B2b, and B3i
• Certified on the CTIA Authorized Equipment List for multiple configuration combinations

Test execution and protocols

• Uses standard cellular signaling channels for direct OTA measurements with IP Multimedia Subsystem (IMS) and E911 support for Voice over LTE (VoLTE) and Voice over NR (VoNR)
• Conducts tests using standard positioning protocols: LPP/Secure User Plane Location (SUPL) for 5G NR, LPP for LTE, Radio Resource Location Services Protocol (RRLP) for GSM, Radio Resource Control (RRC) for WCDMA, and IS-801 for CDMA
• Supports SUPL 2.0 with RRLP and LPP protocol

Flexibility and integration

• Flexible parameters enable test time optimization by modifying test schedules and running only required tests
• Supports OTA performance testing beyond CTIA Test Plan requirements — for example, Total Isotropic Sensitivity (TIS) calculation for A-GPS L1+L5
• OTA Open application programming interface (API) option enables advanced customization and test case development
• Integrates with the Location Technology Solution (LTS) for a combined multi-technology GNSS OTA test solution
• Compatible with SATIMO SMM and ETS-Lindgren EMQuest automation software for chamber integration
