Viavi Solutions and activist shareholder group Sandell Asset Management have been trading open letters about Viavi's future.
During the former JDS Uniphase's split into Viavi and Lumentum, communications and commercial optical products unit, Sandell, publicly urged the JDSU board to consider a sale of Lumentum rather than...
As service providers continue to grow their RF network footprints, they are under tremendous pressure to reduce deployment time to meet constant network demands and reduce OpEx. Fiber to the antenna (FTTA) sites offer significant coverage and capacity benefits, but at the same time...
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...
To meet an increasingly diverse set of usage profiles, mobile network operators are building heterogeneous radio access networks that combine macro, small cell and WiFi technologies from different vendors across 2G, 3G and 4G. The level of diversity in subscriber requirements and the surging...
Suddenly, on a Monday morning around 9:30 am, we started to get calls at the NOC of high dropped calls near a strip mall; this continued till 6 pm. Everything was working fine last week; we did not make any changes to the network,...
Two-thirds of enterprises have deployed some aspect of software-defined networking, according to the ninth annual "State of the Network" report from Viavi Solutions, and around 90% of them already have at least one application in the cloud.
Based on a survey of 740 CIOs, network...
NICE, France – The days of just monitoring network performance metrics to gauge overall performance have given way to much more consumer-facing indicators designed to go beyond service assurance and into gauging customer experience. This trend toward evaluating how the end-user experiences network services...
Network testing company Global Wireless Solutions is challenging RootMetrics' popular crowd-sourced ratings of wireless carriers with a new OneScore rating system for wireless carriers, which takes into consideration both how users want to utilize their devices as well as actual network testing data.
