Aeroflex Limited launched Aeroflex 7100 LTE Digital Radio Test Set that support testing of 3G WCDMA/HSPA and GSM/GPRS, and data call hand-over between LTE and HSPA. Aeroflex 7100 LTE network emulator for testing the RF, baseband and protocol layers of wireless devices supporting multiple Radio Access Technologies. The 7100 LTE Digital Radio Test Set with Option 103 provides comprehensive test capabilities for GSM/GPRS. Option 105 extends the instrument’s capability to include WCDMA and HSPA.

As WCDMA network operators migrate towards LTE, the devices used by their subscribers will need to operate with legacy 2G and 3G networks as well as new LTE networks. Devices must hand over seamlessly between networks when appropriate. Options 103 and 105 for the 7100 LTE Digital Radio Test Set facilitate testing of these multi-mode devices across all the standards they are required to support, and test data hand-over between LTE and HSPA.

The 7100 LTE Digital Radio Test Set is used by RF developers, protocol stack teams, integration test groups and pre-conformance labs that are developing sub-systems and integrated designs that meet the requirements of the LTE standards. The 7100 simulates the E-UTRAN and EPC (Enhanced Packet Core) to provide a realistic test environment for LTE terminals. Test procedures control the characteristics of the simulated network to allow a wide range of repeatable test scenarios to be created. An optional integrated Fading Simulator and AWGN source is available, allowing real-world signal conditions to be created in the lab.

Features of LTE Digital Radio Test Set

  • LTE Development Mode for detailed protocol logging and analysis
  • LTE Call Box Mode for functional and application tests
  • LTE Physical Layer testing and RF parametric tests using Vector Signal Analyzer/Vector Signal Generator (VSA/VSG mode)
  • Data throughput tests under real-world conditions
  • Handover and Multi-RAT testing. LTE Digital Radio Test Set enables emulation of inter-RAT system selection and system reselection procedures for LTE, eHRPD, 1xRTT, GERAN, HSPA and TD-SCDMA. Inter-RAT handover between the non-LTE standards, 2G and 3G, is also supported by extension of the system.
  • Automated test development environments with open Application Programming Interfaces (APIs) which facilitate complete control for development of test scripts.
  • Since LTE is a data standard, a three-phase rollout is taking place to ensure that voice calls are handled appropriately:
    • In phase one, LTE networks are supporting only data-centric devices such as USB modems; 3G handsets will still be used for voice calls.
    • In phase two, handset devices that rely on fallback technologies (WCDMA or GSM) for voice support are being introduced.
    • In phase three, handset devices will be added that use the LTE network for both data and Voice over IP (VoIP). The voice solution will employ the VoLTE (Voice over LTE) standard.
