Baylin Technologies’ subsidiary, Advantech Wireless Technologies, has released a specialised filter which will prevent 5G base stations from interfering with C-Band satellite signals. The filter design has been extensively tested and is available for immediate shipment.
5G rejection filters from Advantech provide a cost-effective way for C-band operators to stay on the air without having to invest in expensive equipment in order to move their services to higher frequency bands.
Many cellular base station transmitters will be allocated to the 5G network resulting in the ubiquitous presence of interfering signals with sufficiently high-power levels to require the use 5G filters to maintain quality of service.
The FCC recently announced its decision to make 280 MHz of C-band spectrum available for 5G services. This decision will accelerate the deployment of 5G services, and will likely cause some interference with satellite service providers who operate in the C-band.
Commenting on the development, John Restivo, President of Advantech Wireless Technologies, said: “We believe that the effects of this decision will be felt, not only in the USA, but in many other regions around the world. Preparations for large-scale 5G deployments are already underway in Europe and Japan. This will prompt existing satellite operators and users of C-band to take preventive measures to protect their existing satellite links from possible interference, or even complete shutdown. With the common use of wide-band receivers, the likelihood of interference is extremely high.”
