Yes, there are testers that support both Wi-Fi and cellular (including 5G) testing.  

These multi-functional tools are designed to streamline, speed up, and smarten up your wireless network testing process, especially in environments where seamless connectivity is non-negotiable.  

Whether you're diagnosing a dodgy signal in a smart office or fine-tuning wireless infrastructure in a large-scale install, these testers have your back. 

 

Why you might need both in one device 

Modern networks aren't just one or the other anymore. They’re often a mix of Wi-Fi access points, 4G/5G backup solutions, and maybe even IoT devices running on different bands. So, having a tester that can handle both wireless flavours saves time, space in your toolkit, and your patience. 

What can these testers actually do? 

Here’s a glimpse at what these hybrid devices usually offer: 

Wi-Fi testing: Signal strength, spectrum analysis, interference detection, SSID scanning 

Cellular testing (4G/5G): Signal quality (RSRP/RSRQ), throughput tests, band locking, cell ID tracking 

RF analysis: Useful for interference mapping and pinpointing rogue signals 

Location-based diagnostics: Some testers include GPS so you can map coverage outdoors, perfect for field work 

Speed and performance tests: Know if your wireless network is walking, jogging, or sprinting 

A few examples to check out 

NetAlly EtherScope® nXG – This handheld unit is a favourite for all-in-one testing. It supports Wi-Fi 6/6E and cellular testing with a USB-based 5G modem. 

Viavi OneAdvisor-800 – Versatile, rugged, and capable of testing everything from fibre to 5G, with Wi-Fi thrown in for good measure. 

Keysight FieldFox analyzers – These lean more into RF testing, great for advanced signal troubleshooting across wireless spectrums. 

Who benefits the most? 

Data installers who need to validate Wi-Fi performance and 5G signal strength in smart buildings or commercial setups 

Electricians branching into network installations and seeking easy diagnostics 

Wholesalers and resellers looking to provide end-to-end wireless test equipment solutions 

End users with in-house IT or facilities teams keeping their networks smooth and speedy 
 

FAQs 

Can one device really test both Wi-Fi and 5G? 

Yes, several high-end testers support both functions. They often use modular designs or USB-based cellular modems to add 5G functionality to existing Wi-Fi testers. 

Are these testers suitable for field use? 

Absolutely. Most models are portable, battery-powered, and designed to survive a few knocks, ideal for on-site work. 

Do I need to be a wireless expert to use them? 

Not at all. While some features get technical, many testers are built with intuitive interfaces, auto-tests, and guided workflows. 

How accurate are these testers? 

Accuracy depends on the brand and model, but well-known names like NetAlly, Viavi, and Keysight have solid reputations for precision and reliability. 

Are there rental options for these testers? 

Yes, many suppliers offer rentals for short-term projects or evaluation periods before buying. Handy if you're testing the testing gear! 
 

Final thoughts 

Wireless networks are evolving fast, and your testing tools need to keep up. If your jobs span both Wi-Fi and cellular, investing in a dual-capable tester is not just convenient, it’s smart business.  

You’ll diagnose faster, impress clients, and probably avoid a few awkward "is it the Wi-Fi or the 5G?" moments.
