Describe how Nokia's TEMS toolset is used for 5G drive testing and benchmarking.

Last updated on 

The TEMS toolset is designed to provide comprehensive testing and monitoring capabilities for mobile networks, enabling operators to assess and optimize the performance of their networks. Here is a technical explanation of how Nokia's TEMS toolset is used for 5G drive testing and benchmarking:

  1. Drive Testing Overview:
    • Purpose: Drive testing involves collecting data on the performance of a mobile network while moving through its coverage area. It helps in evaluating signal strength, call quality, data throughput, and other key performance indicators (KPIs).
    • Measurement Equipment: Nokia's TEMS includes specialized measurement equipment installed in a vehicle. This equipment comprises multiple receivers and transmitters, capable of capturing and analyzing various radio frequency (RF) parameters.
  2. 5G Parameter Measurements:
    • Frequency Bands: TEMS supports measurements across the frequency bands allocated for 5G networks. This includes both sub-6 GHz and mmWave frequency bands.
    • Signal Strength (RSRP, RSRQ): TEMS measures Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) to evaluate the strength and quality of the 5G signal.
  3. Data Throughput Testing:
    • IP Throughput Measurements: TEMS conducts tests to measure the actual data throughput in both uplink and downlink directions. This includes assessing the performance of specific 5G features like beamforming and MIMO (Multiple Input Multiple Output).
  4. Handover and Mobility Testing:
    • Handover Performance: TEMS assesses the efficiency of handovers between 5G cells, ensuring seamless transitions as a mobile device moves through the network.
    • Mobility Robustness: The toolset evaluates the network's ability to maintain a stable connection while the device is in motion, considering factors such as handovers and beam management.
  5. Benchmarking:
    • Comparison with Standards: TEMS benchmarks the performance of a specific 5G network against industry standards and benchmarks. This involves comparing KPIs with predefined values and assessing how well the network meets or exceeds these benchmarks.
  6. Data Analysis and Reporting:
    • Data Collection: TEMS collects a vast amount of data during drive testing, including RF measurements, handover logs, and throughput data.
    • Post-Processing: The collected data is post-processed to generate detailed reports and analytics. This includes creating coverage maps, identifying areas of low signal quality, and pinpointing potential network optimization opportunities.
  7. Visualization and Reporting:
    • User Interface: TEMS provides a user-friendly interface for operators to visualize and analyze the collected data. This includes maps, charts, and graphs representing various network parameters.
    • Custom Reports: Operators can generate customized reports based on specific KPIs and performance metrics. These reports aid in decision-making for network optimization and planning.

It's important to note that the exact features and capabilities of Nokia's TEMS toolset may evolve over time, and users should refer to the latest documentation and releases for the most accurate and up-to-date information.
