BROWSING: RF interference

Maybe not completely—but some proactive work can help identify when PIM problems are likely Interference from passive intermodulation often doesn’t show up as a major issue until a new site starts taking on significant amounts of traffic, or perhaps when a popular new device adds...

When it comes to 5G, no band is perfect. In low bands, 5G coverage is maximized and cell sizes can be quite large, the performance of 5G New Radio is limited because of smaller available channel bandwidths. Meanwhile, high-band, millimeter-wave 5G deployments have a...

As network operators navigate a multi-pronged transformation that encompasses 5G, fiber proliferation, increasingly cloud-based and virtualized networks, one of the challenges that they face is that of radio frequency interference. RF interference is not a new issue in wireless networks, and in fact, some of...

Despite mobile network operators AT&T and Verizon working out a compromise solution with the Federal Aviation Administration to guard against possible C-Band interference in an attempt to avoid air travel impacts, the federal agency has issued more than 1,400 warnings to pilots about the...

A little more than a year ago, Federated Wireless announced that the network of sensors that it had built out along the nation's coastlines was ready to commercially support operations in the Citizens Broadband Radio Service shared spectrum at 3.5 GHz. That Environmental Sensing Capability...

Radio frequency interference issues in mobile networks can significantly impact the customer experience, but they are not always easy to identify and resolve. EXFO has launched the new OpticalRFTM application for its compact and powerful FTB-1 Pro test platform, enabling network engineers and technicians...
