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.
"Despite a recent...
The introduction of new cellular technologies has significantly improved spectral efficiency; however, data demand has outpaced the spectral efficiency benefit. Cellular spectrum holdings cannot keep up with mobile data growth. For operators to meet data demand and retain profitability despite a falling cost per...

In our conversation with Kashif Hussain, Solutions Marketing Manager at Viavi Solutions (until recently JDSU), we talked of how RAN optimization is...
Self-organizing networks (SON) have interested the cellular industry for many years. Work in this area started in 2006 at 3GPP with initial studies on the general concepts and requirements. There was a clear impetus to study SON—networks were becoming larger and more complex, and...
Active Distributed Antenna Systems (DAS) are growing rapidly, yet deploying them successfully and on time remains a challenge faced by the entire ecosystem (service providers, venue owners, NEMs, contractors, neutral hosts.) In this webinar, we will explore the challenges associated with DAS, and review...
In the test and measurement space this week, vendors are gearing up for the CTIA show and highlighting new wares focused on LTE-Advanced and "5G."
- Anritsu launched new support for fading in LTE-A scenarios and support for 4x4 and 8x2 multiple-input/multiple-output technology, additional test...
As testing labs prepare for the new SISO and MIMO OTA testing standards from CTIA, PCTest Engineering Laboratory said it is expandings its capabilities in those areas with a MIMO OTA testing solution from Spirent Communications. Spirent's solution is also going to be used by...
Viavi Solutions has only been operating as an independent entity since Aug. 1, but the company, which inherited JDSU's network services operations, is seeking a new CEO. Tom Waechter, who led JDSU for six years and through the company's split, is leaving Viavi for other pursuits.

Lumentum is the company's optical and...
With over 260 live LTE networks today and another 87 expected to go live this year (GSM Association, 2014), LTE will soon become the dominant technology in many countries. As operators focus on building networks that can handle rich content, where does that leave...
The radio access network is becoming more complex, with cell-site fronthaul architectures ranging from conventional coax to modern fiber. Fiber is increasingly prevalent in all types of cell sites including macrosites, distributed antenna systems (DAS), and small cells.
Spectrum congestion compounds this complexity. Congestion creates interference problems,...
In testing news this week, Viavi and Lumentum, the two companies into which JDSU will split by 3Q of this year, have launched initial websites and logos as part of their progress toward establishing themselves as new companies.
Viavi Solutions is the network visibility-focused company, and...
Until now, cell site turn-up and maintenance have been relatively straightforward procedures-performed on one macro cell with one technology. Today, much has changed-in addition to macro cells, small cells and DAS are proliferating, both indoor and outdoor, covering 2G, 3G, 4G and WiFi.
RF and...
