How to Scale RF testing to a Multi-site and Multi-city Operation

RF testing operates at many different scales. Some testing is independent and can be performed at a single test bench. Operating a larger lab may span multiple rooms or buildings, or involve sites in multiple cities.

How to Manage RF attenuation control to Help Scale Your Wireless Lab

Wireless labs can often have many Remote Radio Units or Remote Radio Heads (RRUs/RRHs) to manage. To conduct testing, these RF ports are connected to RF attenuation equipment before being routed to RF testing stations.

Network Slicing brings revenue opportunities and testing challenges for operators

Mobile carriers have invested considerably in deploying 5G New Radio (NR) and 5G standalone (SA) networks. One of the most promising features of 5G Standalone (SA) to help monetize new services for subscribers is Network Slicing.

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.

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.

Replacing RF patch panels with a software-controlled RF switch matrix

One of the most common issues facing RF lab managers is the cost of setting up various RF testing scenarios, executing the tests, and then tearing down those same setups. Not only is this tedious, time-consuming, and manual labour, it also creates excessive stress and strain on expensive RF components.
