Finding and Resolving RF Interference in the RF lab

Anyone who has tried to perform any RF testing will likely be familiar with one of the most common challenges in the RF lab: interference. Unwanted RF signals in the test environment can easily interrupt tests or spoil results.

Fifteen things you need to know about the spectrum rules for Private 5G networks in Canada

The Canadian government introduced new spectrum licensing rules through Innovation, Science and Economic Development Canada (ISED), allowing private 5G networks, with licenses issued under a Non-Competitive Licensing (NCL) model.

Reducing Power Consumption and Operational Costs in the RF Lab

Finding ways to conserve energy is a priority for every organization. Not only is it important to limit our greenhouse gas emissions, reducing energy use can also have a significant benefit in lowering operating costs.

Handover Testing Made Simple

To simulate a handover, testers must precisely control RF signal strengths from two or more sites simultaneously. Techniques such as MIMO and Carrier Aggregation (CA) combine multiple RF signals together to improve network performance, but testers must manipulate many different signals simultaneously to properly simulate a single handover.

How to Implement Wireless Lab Automation Cost-Effectively

As RF testing becomes more complicated, interest in automation solutions is growing. Automation can save time and improve test repeatability, leading to more reliable results.

Sharing Limited Test Resources Among Multiple Testers

One of the biggest issues seen in RF labs is the need to share expensive and limited test resources among a larger group of testers. Ideally, all testers would have their own, dedicated test equipment. However, much of this equipment is very expensive so this isn’t really a practical approach in most labs.

The Current State of RAN Testing and Deployment Practices

Many operators rely heavily on emulation as part of a reasonable testing strategy. However, emulation, even when done at scale, doesn't accurately reflect the real-world environment and makes too many assumptions about network configuration that don't represent that operator's specific implementation.

How to Use Software Control to Automate RAN Testing for Advanced Mobility Scenarios and Log Analysis

To facilitate test automation each resource in the system is controlled by the orchestration layer and configured according to the scenario being tested. Here we're showing the 5G core, higher levels of RAN, the CU/DU splits, the RRUs, and the devices under test.

Examining How a Mirror Lab Can Replicate and Test Production 4G and 5G Networks Simultaneously

In this blog post we are going to review three configuration examples of lab architecture that mirror the production environment of a mobile network. The first is an operator who wants to be able to test their two-vendor 4G implementation in the lab, where each vendor uses two different configurations.
