At the Mobile World Congress in Barcelona in February 2022, visitors witnessed the first end-to-end commercial 5G Broadcast solution in action. A live signal was transmitted within the exhibition center in Barcelona, using a Rohde & Schwarz transmitter, sectorized antenna systems from Cellnex and a smartphone form-factor test device from Qualcomm Technologies. SPINNER supplied a mask filter from its portfolio.

This new contactless GigE rotary transmission solution now makes it possible for SPINNER to supply products with an especially large inner diameter for dependably transmitting Ethernet protocols across a rotating interface. The joints feature a clear inner diameter of 300 mm and enable reliable Gigabit-Ethernet-LAN transmission. This isn’t possible with conventional sliprings or other technologies.
SPINNER has just released an important component for enabling the concurrent use of TDD and FDD in the 2600 MHz frequency band: our new diplexer BN 570761, which lets you combine bands 7 and 38 without any interference.
The scattering parameters of a device under test (DUT) are measured using a vector network analyzer (VNA). Before starting, however, the VNA should be calibrated applying a set of known calibration standards to identify and minimize systemic errors. Accurate calibration is a must for reliable results.
It’s a major challenge to get optical system components, which typically have low input levels, to work well with conventional radio stations with their high output levels. The time has come for the new, innovative SPINNER RF Power Protector with its globally unique functionality!
The data volumes transmitted by rotating systems in industrial facilities are steadily growing. Users’ expectations are also increasing – not only regarding performance and transmission quality, but also where the reliability of machines is concerned. In many cases, independently of the rotational speeds involved, they need to be able to operate reliably 24/7 without any interruptions.
SPINNER produces components for automated tests that let users significantly reduce both work and costs. Supplementing its highly successful Easy Dock adapters, it is now also supplying low-PIM switches for test applications up to 6 GHz.
The data volumes handled by mobile communication systems have been growing exponentially in recent years and are expected to continue multiplying in the years ahead. The need for ever-faster transmission rates, lower latencies, and larger network capacities can only be met with new technologies such as 5G.
SPINNER has enlarged its portfolio of fiber-optic rotary joints with a new record-setting version with no fewer than 109 channels. This new model is ideally suited for use in offshore and FPSO applications (see below) while delivering clear competitive advantages.
As 5G makes rapid strides worldwide, trials and pilots of 5G Broadcast are also attracting considerable interest. They include projects to test the use of a single-frequency network (SFN) to support both networks operating in broadcasting mode: cellular networks and radio stations. SPINNER sees great potential in this trend and therefore joined the 5G Media Action Group (5G MAG) in mid-2021.
