For NB-IoT applications to function correctly, sufficient network coverage is required. Coverage must be measured to ensure a robust NB-IoT connection. Rohde & Schwarz mobile network testing provides a unique combined test solution that accurately measures the DL coverage using network scanners. It measures the device/network interaction, UL behavior, protocol, signaling load and energy efficiency during communications using NB-IoT devices connected to R&S®ROMES.

RF interference is one of the largest contributors to poor network performance. It shows up in dropped calls and low data throughput rates. Traditionally, interference hunting means you get a list of sites with bad performance from an OSS. This defines the areas for interference hunting quite well.If, however, the problem remains after attempts at mitigation, it could be because other sources often mask symptoms of RF interference. Usually the strongest masking is due to the overlap between the interference signal and your network's signals. Analysis could involve complete cities or even countries, an error-prone task when using traditional spectrum analyzers and/or portable receivers and one that consumes a significant amount of time and budget.A more automated solution for larger areas can make the effort involved more manageable. The Rohde & Schwarz network scanner family (R&S®TSME, R&S®TSMA and R&S®TSMW) plus the network problem analyzer (NPA) feature of the R&S®ROMES4 measurement software is such a solution. It allows you to perform a fast drive test with a fleet of cars and collect spectrum data for your targeted or even complete network area in next to no time. Back at your office, the NPA tells you where to send dedicated interference hunting teams with an analyzer or receiver to track down the source of interference. This paper introduces the approach in detail.

MIMO technologies are an essential component of state-of-the-art mobile radio systems and are key to achieving extremely ambitious capacity goals that include providing stable data rates in the two- to three-digit Megabit per second range over a broad coverage area. However, the effectiveness of these technologies is not always guaranteed. A channel state matrix can provide the information needed to determine whether spatial multiplexing is possible for multilayer data transmission. Simple indicators for evaluating the mobile radio channel are derived from the channel matrix. This white paper presents these parameters and discusses them based on simulated and real coverage measurement results.

For optimization of mobile communication networks, drive tests with coverage measurement systems are being performed. The coverage measurement platform provided by Rohde & Schwarz is based on R&S® ROMES, which is the application software to define and setup measurement devices, acquire and store the measurement data and displaying measured data during the measurement period and a later replay. Additional drivers are used for attaching different measurement devices, such as the Rohde & Schwarz Universal Radio Network Analyzers TSMQ or TSMW or test mobiles from different manufacturers. Depending on the required measurement tasks, R&S® ROMES can be configured freely to adapt to the user’s needs. As long as the measurements are performed in an outdoor environment using a vehicle traveling around, size and weight of the measurement system is not a problem. As more and more measurements are performed in an indoor environment by walking around, size, weight and mechanical handling is an issue of interest. ROMES® can be used in a light weight configuration, which is small enough to be carried in a back pack. For use of R&S® ROMES with R&S® TSMW in an indoor environment, the Backpack System R&S® TSMW-Z3 has been designed. The system includes a mini PC with R&S® ROMES which needs to be controlled remotely. This application note describes, how to establish a Wireless Lan Access Point on the R&S® ROMES PC and to setup a wireless LAN connection between an Apple iPad® and the mini PC.
