A report from Viavi Solutions claims 12 operators have already carried out field testing of 5G technology.
Twenty-five mobile operators have announced plans for lab testing of “5G” technologies, according to a recent report by Viavi Solutions. Of those 25 operators, 12...
Keysight Technologies reported flat year-over-year revenues in the most recent quarter, but delivered at the high end of its guidance to Wall Street.
Revenues were $751 million for Keysight's fiscal fourth quarter, compared to $750 million during the same period last year. Keysight President and CEO...
Rohde and Schwarz says it has developed the first tester for measuring over-the-air transmit power in millimeter wave frequencies, with support for development of both cellular "5G" and the frequencies planned for use in 802.11ad and 802.11ay.
The NRPM OTA power measurement test solution has...
Best practices help operators reduce opex and assure quality of experience
Tremendous cost pressure and an incredibly competitive carrier marketplace have created a dynamic in the telecom industry marked by a pressing need to combat churn by ensuring quality of experience while maximizing network investments...
Streamline troubleshooting to maximize RF investments and cut opex
RF interference, whether it’s PIM, electrical or out-of-band emissions, wreaks havoc on mobile networks. Interference hunting and troubleshooting take up valuable and costly man hours while generating dropped calls and poor data throughput, which can translate...
As CPRI and OBSAI gain traction, stay competitive while cutting costs
To keep up with data-hungry customers, carriers are working to add capacity and flexibility to their networks. This trend has resulted in a movement to centralized Radio Access Network, which separates the radio into...
Small cell and DAS deployments require careful planning and coordination of a number of different processes. Zoning, permitting, lease agreements, backhaul, power, and "negative assets" all need to be evaluated when a site is chosen. A new site's planned performance needs to be projected...
Modern cell sites have a distributed architecture, where the base-station transceiver subsystem is divided into two main elements:
1. A baseband unit (BBU) performing base band functions in the digital domain, which resides at the base of the tower;
2. and, a remote radio head (RRH)...
Learn how to pinpoint uplink interference while reducing tower climbs and saving money
Interference can make or break a cell site commissioning. From the macro tower layer to indoor small cell deployments, interference costs time and money while creating the potential for customer churn based...
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...
Simplifying tower test and measurement saves time and money while driving safety and industry competitiveness
From installation and commissioning to ongoing maintenance activities, cell towers require a great deal of capital and operational expense. Coupled with the incredibly competitive service provider landscape, cost pressures create...
