5G & Smart Solutions

SEGRON’s automated testing solutions increase efficiency, improve quality of service and reduce time-to-market.

Across Industries, Quality Assurance Has Always Been a Business Critical Function

The basic criteria to ensure proper quality in the complex network environment of a modern company is proper testing and verification of the network services using the latest smartphones and devices.

With the introduction of Voice over LTE and VoWiFi, voice services have become a layer on top of the data services and merged together by using the same network. The quality assurance for data services (the Internet) must be regarded as equally important as it was for the former voice domain.

Not only businesses, but also consumers — all of society — have become highly dependent on data services.

5G has the potential to increase connectivity in rural areas and along rail lines, power smart manufacturing 4.0, and run smart cities and towns. However, this potential will not be attained until companies have had the chance to test things out in a safe environment.

Therefore, the quality of all telco operations has become pivotal for operators, their customers and regulators and as a result, automated testing indispensable.

SEGRON's Solution 5g

Prepare Your Network for 5G

5G demands more frequent and more innovative testing strategies.

Is your network ready for latency rates of 1 millisecond? The advent of 5G means customers expect speeds of up to 100 times faster than current networks, thanks to much greater bandwidth and exponentially lower latency rates.

Keep up with the expansion of connected devices. The incredible volume and variety of connected devices continues to rise. And with the proliferation of the internet of things (IoT), customers will expect constant connectivity on everything from their watches and phones to their cars, refrigerators and much more.

As the number of devices keeps increasing, so do the demands on telco operators’ ability to test these devices. The devices themselves require conformance and service testing, while the networks will more exhaustive verification and quality assurance testing. All of this comes at a time when service verification has already become much more complex and difficult. Automated device testing is a natural solution to overcome the rising demand in testing and requirements to shorten testing throughput time.

Streamline testing operations and reduce costs. What kinds of tools are on your testing bench? As telecommunications evolve, so should those tools. For instance, a modern testing lab needs to cover the complete functional spectrum starting from 2G to VoLTE/VoWifi and ending with 5G. 

Considering the complex interworking and interfaces between the radio, core and access parts in voice and data, it is challenging to maintain all of these technologies. Permanent monitoring and verification is required to ensure the lab’s performance and stability. With a modern test automation solution, heartbeat testing and more complex service availability testing can be done on a regular basis. 

Operators can save long lead times due to lab preparation and avoid potentially cost-prohibitive investments needed for lab clean-up and troubleshooting while running projects, which can cause further delays in launching new services. With a trusted test automation partner and solution, you can keep your lab up-to-date, reflecting your live network as close as possible.

Complex technologies require efficient verification processes. It’s no secret that telecommunications networks have become much more complex in the past decades. Operators must test and maintain 2G, 3G and LTE radio access networks in parallel. The future brings 5G, network virtualization and an explosion in IoT-enabled devices, which will only further complicate the network verification process. 

Pair these complexities with higher expectations from customers, who increasingly rely on a host of connected devices, and it’s easy to see why automated network verification would be an exceptionally wise choice. 

Thanks to many years of international experience, SEGRON’s network verification engineers bring broad technical knowledge and expertise in automated testing. They are specialized in speeding up verification and delivering reproducible results. SEGRON verification engineers use hardware and software tools developed in-house, and we tailor our services to accommodate your needs.
