BROWSING: Interference

PIM is an escalating issue in 5G midband networks deployed in TDD spectrum Passive intermodulation is interference that is generated when two or more simultaneous signals interact in a nonlinear environment, where passive components (as opposed to transmitting ones) can cause new, unwanted signal noise...

Passive intermodulation (PIM) is interference that is generated when two or more simultaneous signals interact in a nonlinear environment, where passive components (as opposed to transmitting ones) can cause new, unwanted signal noise to be generated that impacts the performance of the RF system.  Why...

The Federal Communications Commission has formally begun a proceeding to gather information about wireless receiver performance, and how it might encourage better performance in wireless receivers—an effort that has bipartisan support on the commission, and which could represent a turning point for the design...

Automated Frequency Coordination (AFC) is a spectrum use coordination system designed specifically for 6 GHz operation In order for unlicensed Wi-Fi 7 (or 802.11be) devices to play nice in the 6 GHz band with the licensed users already occupying that band, the Federal Communications...

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...

Interference that can degrade capacity and quality of service is becoming ever more troublesome as operators roll out 5G NR using new bands that previously contained other services. This is particularly important for the rollout of 5G NR because of its demanding use cases...

Interference in the Radio Access Network is ubiquitous and becoming more critical as the deployment of the latest cellular standards brings increased sensitivity and subsequent degradation of network capacity and subscriber Quality of Experience. In this white paper, we will explore the topic of interference...

Oscillation caused by insufficient path loss between a bidirectional amplifier’s (BDA) donor and serving antennas is one of the most common and most serious forms of interference in cellular networks.   This white paper provides a general overview of how BDAs work, the conditions leading to...

The Federal Communications Commission has proposed a $2.8 million fine against recreational drone company HobbyKing, for selling radio frequency transmitter devices for drones which operate in unauthorized RF bands and at higher power levels than allowed under U.S. rules. HobbyKing operates in both the U.S....

  Overcoming wireless network interference in the field is a major challenge given the exponential growth in demand for mobile services and the volume of wireless signals traversing today’s networks. For complete assessment, technicians and engineers typically have to carry multiple instruments in their kit...

  Learn how remote spectrum monitors from Anritsu can save time, money and company resources Consumer data use, particularly mobile video, is growing at a remarkable pace with no signs slowing, which is prompting carriers to continually invest in network densification while navigating the pressure to...

The radio environment is getting ever more complex and crowded, as new technologies, new devices and new spectrum bands come into play. Meanwhile, dynamic spectrum sharing is becoming the new paradigm for policy as regulators seek to promote more efficient use of scarce spectrum...

With the rapid expansion of wireless communications, the need for robust networks relatively free of interference continues to grow.

Spotting Interference or What Am I looking for? Scroll down to view white paper As wireless services grow, due to a drive for increased download speeds and capacity, interference, once uncommon, becomes a fact of life for wireless and broadcast services. A metropolitan area of a million people...

Learn practical strategies to overcome RF and microwave interference challenges in the field by downloading Keysight Technologies’ new application note on real-time spectrum analysis (RTSA). Read about the different types of interference encountered in wireless communication networks. Uncover the drawbacks associated with traditional interference...

Interference problems have plagued LTE networks from the start. External sources of interference, from streetlights to baby monitors to rogue base stations, can slow network data speeds or disrupt connectivity. Nevertheless, external interference is often the last problem network operators tackle. This is primarily due...

A conversation about interference with Tom Elliott, Sr. Product Manager, Anritsu The below is only a summary. Download a transcript of the complete interview and the full report “Massively densified networks. Why we need them and how we can build them.” Interference identification and management in dense, multilayer networks...

Locating an interference source is nothing short of finding a needle in a haystack. From a service provider perspective, RF interference is much more than a nuisance. If it is not eliminated, it can negatively impact service providers’ CAPEX, and OPEX, and can cause...

Efficient interference handling will be essential to optimizing customer experience as network connections grow exponentially Viavi Solutions announced the availability of InterferenceAdvisor™, an automated interference hunting solution which can dramatically reduce the amount of time it takes to locate mobile network interference sources. What typically...

Quickly identify and isolate RF interference with the broadband log periodic antenna The Viavi Solutions® broadband log periodic antenna is an extremely cost-effective solution that works with an AntennaAdvisor handle and CellAdvisor base station analyzer to let technicians at any skill level quickly identify and...

A service provider eliminates interference from an unauthorized signal booster thanks to Viavi InterferenceAdvisor Mobile repeaters or signal boosters are wireless devices used to enhance coverage by amplifying and re-transmitting the mobile signals in areas of poor signal quality. At a subscriber level, with access...

Quickly locate RF interference sources with advanced interference hunting techniques. With RF spectrum proliferation, interference issues are inevitable. Interference can reduce coverage, capacity, and throughput by desensitizing receivers, increasing noise floors, and lowering signal-to-noise ratio (SNR). All of this has a major impact on user...

CPRI testing at the base station reduces truck rolls, tower climbs and OpEx Carriers are increasingly turning to centralized Radio Access Network (C-RAN) architecture and CPRI (Common Public Radio Interface) to provide network flexibility, to be able to scale quickly, and to be able to...
