Advantech Wireless Technologies has released a filter designed to prevent 5G base stations from interfering with C-Band satellite signals. The filter is available for immediate shipment.

The FCC recently announced a plan to allocate 280 MHz of the 3.7 to 4.2 GHz satellite band for 5G, leaving the upper 200 MHz for satellite to ground station transmissions. The proximity of high power base stations will likely cause interference with ground station receivers, necessitating filters to mitigate interference and maintain quality of service.

5G rejection filters from Advantech are a cost-effective way for C-Band operators to stay on the air without having to invest in expensive equipment to move to higher frequencies.

“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 wideband receivers, the likelihood of interference is extremely high.” — John Restivo, president of Advantech Wireless Technologies
