We identify issues, improve functionality and enhance performance at RF so that you can fully focus on perfecting application level features
Z2Labs is Zoltan Papp and Zoltan Doczi, two passionate electronics engineers with over 20 years of experience in RF hardware. Former coworkers, they’ve now joined forces to offer more comprehensive services.
We do whatever it takes powered by our experience and intuition to get to the bottom of RF issues as fast as possible without wasting time. We cut up, patch, FW hack PCBs to find the root cause then suggest production level solutions on PCB and in SW.
Augmented with our network of fellow independent HW/SW experts there is not much we could not cover around RF HW and application troubleshooting. We pride ourselves in tackling issues head-on, making decisions fast and communicating clearly.
Got stuck at an RF/EMC performance issue - lack of range, regulatory failure, immunity concern - that hinders the whole project and burns money? We might just be the answer.
You have a great idea that has wireless connectivity, but you don't have in-house expertise for making it perform well? We can take the burden off your shoulders.
Is your prototype product passing RF and EMC regulatory requirements? We test it for you. Going forward with a non-compliant prototype is costly.
Have a project in mind with RF connectivity and you are at loss looking at sheer number of technologies and requirements? We help you guide you to the best selection.
Does your system level RF design cater for all application and regulatory requirements? A mistake at this stage is costly moving forward. We can help double check all requirements.
We had a throughput issue on one of our newly developed radio designs. Zoltan P quickly identified the root cause of the issue and worked through some configuration iterations to arrive at acceptable performance. He was to the point and never let up until a solution was found.

Our end nodes were getting out of time sync on our narrowband radio protocol at Telensa. Zoltan zoomed in on the possible root causes and managed to recommend a radio configuration change on the SiliconLabs IC we used that saved the day.
Development director at telensa
Zoltan helps us develop RF hardware for cellular applications on drones. He has remarkable hands-on skills when it comes to RF system and hardware design. He communicates with confidence and is able to provide strategical advice on the most optimal R&D approach in addition to just technical contributions.

We are two independent RF specialists Zoltan Papp and Zoltan Doczi based in Budapest, Hungary. We have been fixing up RF issues for quite some time and decided in 2025 to join forces to give a more comprehensive service. We are further augmented by our fellow independent peers with diverse expertise from embedded SW development to SDR programming.
When you experience RF communication related issues on your prototype product, such as short range, intermittent malfunction, regulatory compliance failure and
We have vast experience in sub GHz and 2.4 GHz ISM band applications including proprietary (metering, social alarms, Sigfox, Lora) and standards based (BLE, Zigbee, Z-wave, WiFi) RF protocols.
We have worked with radio products from TI, SiliconLabs, Nordic, ST, SemTech, ESP, Qorvo, ADI, Mediatek.
We have further experience in the cellular world with NB-IoT and 3G/4G modems. All above said any RF up until 5 GHz we can handle with confidence but we are not shying away from going above.
We believe in delivering solutions and answers before full compensation. We start working on a modest hourly rate basis and only charge a bonus fee if the project has been completed with firm conclusions to the customer’s satisfaction. For more details on pricing and payment options do not hesitate to reach out to us.
The time varies quite a bit with the issue at hand. First two steps are: understanding the symptoms / reviewing debug efforts from the customer side, and then reproducing the issue on a setup we can start measuring on. Once the reproducer is done, we can give you a more accurate estimate. Typical times for the whole process vary from 20 to 200 hours.
Typically our customers send the hardware to our office with instructions, and we take it from there. We prefer using our lab, but we can be flexible depending on the project.
Yes we do. Besides troubleshooting we do take on designs from scratch as well. There are two levels to that activity:
Yes, we sign NDAs. We can even sign it for the first consultation session.
You can contact us via email.
We usually start with a kickoff meeting where you present your issues and requirements. We come back with a quote and time schedule within one week after the meeting.
