Have you ever been in an online meeting where the sounds wasn’t clear? Or streaming a video when it suddenly started buffering? It all comes down to one thing: network quality.

Behind the scenes, there are many processes to make sure signals stay stable and your digital experience run seamlessly. The process is called network testing.

Network testing is not just about checking whether there’s a signal or not. It involves specific methods, special equipment, and engineer teams who go directly into the field to measure all the network performance in real time. Three main methods which often used are DriveTest, Network Benchmarking, and Walk Test.

Drive Test

Imagine a team of engineers driving around the city with specialized equipment in their car. That’s what we call a Drive Test.

They follow specific routes to measure network quality in real time, directly from on-the-ground conditions.

What do they measure?

Coverage Quality – How strong and widespread the signal is
Download/Upload Speed – Actual user speeds in real-world conditions
Latency & Jitter – How long data takes to travel, crucial for video calls and gaming
Call Setup Success Rate – How reliably calls can be connected without failure
Web/App Performance – How quickly apps like YouTube or Instagram load

The results from Drive Tests help operators understand whether their networks remain stable on highways, in residential areas, and even in busy city centers.

Network Benchmarking

If a Drive Test focuses on one operator, Network Benchmarking takes it to the next level.This method compares the performance of multiple operators within the same area, across different technologies (like 4G and 5G), and even across regions.

Why does it matter?‍

Objective – Provides real, unbiased comparisons between operators
Strategic – Helps operators identify their strengths and weaknesses against competitors
Customer-Centric – Drives better quality of service for end users
Transparent – Builds public trust in the telecom industry
Regulatory Support – Helps governments monitor and uphold national network standards

With benchmarking, the public can see which operators truly deliver the best quality, not just the ones with the flashiest ads.

Walk Test

Not every area can be reached by car.That’s where the Walk Test comes in. Engineers physically walkthrough public spaces, buildings, and even indoor areas while carrying specialized testing equipment.

Why is it relevant?
‍

Real User Experience – Captures network performance where people actually live, work, and move
Indoor & High-Density Areas – Essential for offices, malls, and stadiums packed with users
Detailed & Accurate – Data is more precise, revealing small dead zones or weak spots that a Drive Test might miss

Walk Tests ensure that we stay connected even in places like malls or crowded indoor spaces.

Our digital world relies more than ever on fast, reliable connections. From Drive Tests to Benchmarking to Walk Tests, each method plays a crucial role in delivering a smooth, uninterrupted online experience.

So next time you enjoy a movie without buffering or join a virtual meeting without delays, remember: there’s a dedicated team working behind the scenes to ensure stronger signals, better experience.
