Narrowband Internet of Things Measurements

The Internet of Things (IoT) is considered the driving force of current and future wireless communications. In release 13, 3GPP has specified Narrowband-IoT (NB-IoT) as a new physical layer. This application note gives a short introduction to NB-IoT and shows the easy measurements with Rohde & Schwarz instruments.

Antenna Beam Characterization of 5G Mobile Devices and Base Stations Using the R&S®NRPM Over-the-Air (OTA) Power Measurement Solution

Radio frequencies in bands around 28 GHz are being discussed as candidates for mobile communications of the fifth generation (5G). Beam steering will be a key feature in the context of 5G. It will be a major challenge to test the beam steering capabilities of base stations and user equipment in every phase from research…

Characterizing Active Phased Array Antennas

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well. This application note aims to explain test procedures and…

Millimeter-Wave Beamforming: Antenna Arrays & Characterization

Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G bands. Antennas for 5G applications make use of the shorter element sizes at these high frequencies to incorporate a larger count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in next…

OTA testing to gain importance with 5G

The next few years will see many more wireless users connect to wireless networks. Wireless users will expect a higher level of quality and accessibility from all their devices. Thus, carriers will need to provide better reliability in the network and in devices. The result: Testing will, therefore, need to evolve to more closely emulate…

Complimentary Poster: Narrowband Internet of Things

3GPP release 13 has specified a new radio interface, the Narrowband Internet of Things (NB-IoT). Tightly coupled with LTE, NB-IoT is optimized for machine type traffic. It is relatively simple by design, with an emphasis on cost reduction and minimal battery consumption. Please note that we only can ship to the U.S. and Canada at…
