How to Set Up PCTEL Scanner Channels and Troubleshoot Missing Data during Walk Tests

Updated
Introduction

Introduction

This guide provides step-by-step instructions for setting up scanner channels on PCTEL scanning receivers and troubleshooting common issues such as missing data during walk tests. It is intended for network engineers and field technicians using PCTEL products to ensure accurate and reliable wireless network measurements.

Setting Up Scanner Channels on PCTEL Devices

Before configuring channels, confirm that your PCTEL scanner is equipped with the necessary technology options (e.g., LTE, 5G, WiFi). Proper channel setup is essential for capturing accurate measurement data during testing.

  1. Access the scanner's configuration interface through the PCTEL application or directly on the device.
  2. Navigate to the channel setup or measurements section.
  3. Select or add the desired channels relevant to your test scope, ensuring you include all necessary PCIs or frequencies.
  4. Adjust the channel bandwidth settings in the measurements column according to the network technology standards.
  5. Save and apply the configuration before starting measurement collection.

Troubleshooting Missing Data During Walk Tests

If you observe missing or incomplete data during walk tests, consider the following troubleshooting steps to identify and resolve common causes.

1. Verify CINR Levels

Check the Carrier to Interference-plus-Noise Ratio (CINR) values during the test. Low CINR can cause poor data capture or loss. Ensure the measurement locations have adequate signal quality.

2. Check for Interference

Interference from other signals or equipment can impact scanner performance. Use PCTEL SeeHawk® spectrum monitoring tools or interference locating systems to detect and mitigate interference sources.

3. Optimize Channel and PCI Counts

Having too many channels or Physical Cell Identities (PCIs) configured can overload the scanner and result in missing data. Try reducing the number of channels or PCIs to the essential subset for the test.

4. Collect Data Using PCTEL Application for Further Review

If issues persist after the above checks, collect detailed data logs using the PCTEL software applications such as SeeHawk Touch or Collect. These logs can be analyzed by technical support to identify underlying problems.
