Mobile network operators expect their subscribers' 5G mobile experience to be amazingly fast and unfailingly reliable.
New 5G network access equipment must deliver broader bandwidths, higher frequencies, lower latencies, and enable machine-to-machine communication necessary to enable a massively connected Internet of Things. As you bring new 5G network equipment to market, make sure you are testing against the most realistic 5G conditions.
Generate and Analyze 5G NR Waveforms
5G wireless systems need to handle a variety of traffic types, including enhanced mobile broadband and machine-type communication. New types of multiple access schemes, waveforms, and modulation formats will all be part of the standard. As the standard evolves, so do the requirements of your test and measurement systems.
Accelerate your research by generating and analyzing the latest wideband 5G candidate waveforms. With support for many frequency bands, including mmWave, as well as modulation bandwidths, you will be able to adapt your test solution as 5G evolves.
In addition, coexistence testing determines any performance impairment caused by RF interference from a cellular connection onto Wi-Fi frequency bands. Evaluate your test solutions on how well they isolate signals to ensure they are non-interfering.
Validate Multi-Channel gNB Performance
The 5G next-generation base transceiver station or gNodeB (gNB) connects subscriber user equipment (UE) devices to the mobile network. Many of the gNB throughput improvements come from multiple input and multiple output (MIMO) antenna systems that improve cellular connection reliability and quality by leveraging multipath transmission in urban environments, and from beamforming systems that focus energy transmissions to optimally target specific users. This reduces base station power consumption and enables very high-gain links necessary to overcome mmWave channel losses. These advanced technologies dramatically increase the complexity of the radio access network (RAN).
Make sure your 4G eNodeB (eNB) and 5G gNodeB (gNB) base station test solution can easily generate and analyze large numbers of highly-calibrated phase-coherent RF streams. Test your MIMO and beamforming systems thoroughly, including active antenna systems (AAS) and remote radio heads (RRH). Make sure your solution can also extend to meet future test requirements, such as 3-D beam visualization including per-layer modulation quality with amplitude, phase, and timing options.
Generate Massive Amounts of 5G Traffic
5G networks need to deliver a dramatically-improved user experience for enhanced mobile broadband (eMBB) while also handling massive machine-type communications (mMTC). These requirements are often at odds with each other — higher bandwidths for users cannot interfere with thousands of intermittently-bursty machine-driven IoT connections. To properly access new equipment and network architectures, you need to emulate massive amounts of UE devices accessing a variety of applications.
Accurately simulate the latest 4G and 5G network traffic — web, video, voice, storage, security, and other protocols — to evaluate your cellular network equipment and infrastructure. Create realistic traffic flows, including the latest application protocols, SSL security features, and diverse user behaviors — to properly evaluate user quality of experience (QoE) and quality of service (QoS). Stress-test your network and determine what happens in the most challenging 5G scenarios.
Verify 5G Coverage In The Field
Once you complete testing your gNB equipment and network in the lab, you need to test in the field across different conditions using mobile devices.
Make sure you have the ability to measure, analyze, and visualize signal power levels from each beam emitted by your sub-6 GHz or mmWave gNB with our Nemo Outdoor drive test solution. Verify signal propagation and attenuation, perform band clearing measurements, and run interference testing all in real-world field conditions.
