RF and QoS measurements in one tool with instant results

R&S®ROMES4 is the universal software platform for network engineering, network optimization and troubleshooting. In combination with test mobile phones and drive test scanners it provides solutions for all essential tasks involved in coverage measurements, interference identification and QoS. In addition to measuring and displaying test parameters, data is processed instantly and statistics are calculated in realtime.

Features & benefits

NB-IoT testing

R&S®ROMES4 provides combined scanner and device NB-IoT network testing capabilities

NB-IoT is a completely new network layer, promising deep indoor coverage and low device power consumption at a low cost point. R&S®ROMES4 in combination with an R&S®TSMx scanner and NB-IoT test-devices provides complete RF and QoS testing capabilities for engineering and network optimization. It supporst QualComm and HiSilicon Neul based devices. Detailed trace and visualization capabilities enable full control of the device and its interaction with the network.

TETRA network evaluation with scanners and handsets

R&S®ROMES4 in combination with the network problem analyzer (NPA) offers the complete tool chain to measure the quality of a TETRA network and easily detect problem spots. It supports R&S®TSMx scanners for TETRA as well as leading TETRA handsets for QoS measurements and speech quality analysis. For easy and flexible measurement, all equipment can be carried in a compact backpack and controlled via a tablet.

TETRA measurement system

Network problem analyzer

The network problem analyzer (NPA) automatically analyzes drive test data to identify problem spots in the network.

The NPA is ideal for for network optimization. It is the postprocessing tool for R&S®ROMES4 and QualiPoc measurement data. The NPA can process multiple files and check the network for RF issues, such as lack of coverage and high interference, or service issues, such as low throughput and dropped calls. The NPA supports latest technologies, such as NB-IoT.

BTS position estimation

Automatically identify base station locations based on scanner measurements.

In combination with an R&S®TSMx scanner, R&S®ROMES4 can estimate the location of base stations during the drive test. GSM, WCDMA, LTE-FDD/TDD, CDMA2000, 1xEVDO, WiMAX and Tetra base stations are supported. Network operators can identify other networks’ base station locations in case of interference or for co-siting requirements. It is also possible to gain knowledge about competitor network rollouts.

Automatic channel detection (ACD)

Faster setup and fewer redrives when using a scanner

The automatic channel detection feature enables the R&S®TSMx drive test scanners to automatically detect active channels in a specified band. GSM, LTE, UMTS and CDMA2000®/1xEV-DO networks are supported. The measurement system dynamically identifies new channels and adds them to the workspace during the drive. This is particularly relevant in networks deployed in a shared spectrum with other cellular standards, where channel frequency and channel bandwidth frequently change

Uplink and downlink allocation

Assessing the cell load and number of users with passive scanner measurements

R&S®ROMES4 in combination with an R&S®TSMx scanner can measure the eNodeB scheduler allocations in the LTE downlink and uplink direction without the need for a SIM card. When performing tests with a UE, the scanner data is used to assess the load in the cell: if the cell is heavily loaded, quite naturally the UE can only get fewer resources from the scheduler, leading to a reduced throughput. If, however, the cell is not loaded, a low UE throughput must be caused by other reasons, calling for optimization action.

Multiple measurement devices

Testing latest features even with pre-commercial devices

R&S®ROMES4 supports Qualcomm and Exynos chipset based devices for mobile measurements. Varous data jobs can be performed with commercial and even precommercial devices connected to R&S®ROMES4, while receiving full layer 3 information. When using a QualiPoc Android, speech quality can also be evaluated with the POLQA algorithm (ITU-T P.863), and several typical applications such as Facebook, Dropbox and YouTube can be used as test cases.
