Introduction to 5G Base Stations

As the latest generation of mobile communication technology, 5G provides ultra-high data rates, ultra-low latency, high reliability, and massive connectivity. To support these requirements, network infrastructure must be continuously upgraded. The 5G base station—being the core of the 5G network—is responsible for providing coverage, capacity, and stable connectivity. Its main features include:

1. Dense Deployment

To achieve higher capacity and better coverage, 5G networks rely on a large number of small cells deployed across streets, buildings, and diverse environments.

2. Multi-Band Support

5G base stations operate across both sub-6 GHz and millimeter-wave spectrum bands, allowing flexible adaptation to different coverage and throughput requirements.

3. Massive MIMO Antenna Arrays

Large-scale MIMO (Multiple-Input Multiple-Output) enables simultaneous service for multiple users, significantly improving spectrum utilization efficiency.

4. Ultra-Low Latency

Through optimized air-interface protocols and an advanced network architecture, 5G base stations can achieve end-to-end latency as low as 1 ms, supporting applications requiring real-time responsiveness.

Additionally, 5G base stations support dynamic beamforming, network slicing, virtualization, automatic configuration, and advanced power-efficient hardware.

How to Quickly Test 5G Base Station Performance

As 5G deployments expand, fast and accurate testing is essential for operators, integrators, and field maintenance teams. Below are the key testing items and recommended communication test instruments.

1. Spectrum Analysis & Interference Detection

Recommended instruments:

• Spectrum analyzers
  (for spectrum analysis, interference detection, and signal quality evaluation)

Steps:

1. Turn on the spectrum analyzer and select the target frequency band.
2. Scan the 5G base station’s operating frequencies to measure signal strength and spectral quality.
3. Identify adjacent-channel interference or other external sources of RF disturbance.

Purpose:
To ensure the transmitted signal meets regulatory specifications and is not affected by external interference.

2. Signal Strength & Coverage Evaluation

Recommended instruments:

• Field signal strength meter / RF field tester

Steps:

1. Measure signal strength at multiple locations around the 5G base station.
2. Record measurement data and generate a coverage map.
3. Compare results with planned coverage requirements.

Purpose:
To verify whether 5G coverage and signal levels meet the network design targets.

3. Network Performance Testing

Recommended instruments:

• Network tester
  (throughput test, latency test, packet loss measurement)
• Ethernet tester
  (for testing the wired backhaul, Ethernet links, and fronthaul network performance)

Steps:

1. Connect the network tester to the 5G base station or its backhaul link.
2. Perform uplink and downlink throughput, latency, jitter, and packet loss tests.
3. Compare measured performance with the operator’s SLA.

Purpose:
To evaluate overall base station performance in terms of bandwidth, stability, latency, and packet reliability.

4. Cable & Antenna System Testing

Recommended instruments:

• Cable and antenna analyzer
  (VSWR, return loss, distance-to-fault testing)

Steps:

1. Use a cable and antenna analyzer to test the antenna system’s VSWR and return loss.
2. Identify cable degradation, loose connectors, excessive reflection, or abnormal feeder loss.
3. Verify antenna performance after installation or maintenance.

Purpose:
To ensure the antenna-feeder system operates efficiently, minimizing losses and avoiding RF performance degradation.

5. Mobile Terminal Simulation & User Experience Testing

Recommended instruments:

• Mobile terminal analyzer / UE simulator

Steps:

1. Simulate user equipment (UE) and connect to the 5G base station.
2. Test connection stability, mobile throughput, and service quality.
3. Validate real-world performance from the user’s perspective.

Purpose:
To assess actual user experience and verify that the base station provides stable and high-quality service.
