This guide contains a comprehensive overview of LTE technology and the testing issues it presents to both the engineer and the network operator. This 60-page document is an essential reference for engineers wanting to gain a better understanding of LTE.
White Paper: Understanding Carrier Aggregation
The overall goal of using Carrier Aggregation is to provide enhanced and consistent user experience across the cell by maximizing the peak data rate and throughput, improving mobility, providing a better and more consistent QoS to users, and enabling interference management with intelligent allocations of resources. This white paper is a guide to understanding the different types of Carrier Aggregation, and what is needed for its implementation and testing.
Any new mobile network generation of telecom technology, such as what is now being called “5G,” comes with a completely new architecture that includes things like new radio access technology, and new standards to address current subscriber demands that previous technologies could not answer. This white paper explains the technology and society trends that are driving the future of mobile broadband networks, and predict a set of future requirements.
Troubleshooting Passive Intermodulation Problems In The Field
It is broadly understood that Passive Intermodulation (PIM) is a formidable issue within the cellular industry. This type of test has been in use for 15 years or more within the OEM industry throughout the world. As extra cellular transmitters and modulation formats are commissioned into service in new or existing sites, the statistical performance can appear to change dramatically. Ultimately, this can result in poor site/sector performance and reduced coverage, and this is why testing for PIM is now required in the field. The purpose of this article is to introduce the troubleshooting methods currently
used in the cellular construction industry as well as to offer some background
knowledge of Passive Inter-Modulation (PIM).By Nicholas Cannon, Anritsu Company
Modern Architecture Advances Vector Network Analyzer Performance
This white paper discusses the limitations of prior VNA architectures and how Anritsu differentiates their line of analyzers through the use of high-frequency technology.
Meeting The Requirements For Voice Over LTE (VoLTE)
The motivation for the deployment of 3GPP Long-term Evolution (LTE) mobile broadband technology is simple: All things considered, LTE delivers to carriers the lowest cost-per-transported bit.
White Paper: LTE Resource Guide
Anritsu has a line of products especially for LTE/LTE-A R7D and Conformance/Carrier Acceptance Test solutions. This white paper provides information on what products Anritsu offers to ensure the performance and quality of LTE/LTE-A devices and network equipment.
Field Test Solutions To Locate PIM Sources And Optimize Network Performance
Operators promise that their LTE networks provide high speed and high bandwidth, a claim that field engineers and technicians work diligently to keep. Ensuring that level of performance has never been easy, and it continues to be a challenge due to passive intermodulation (PIM), a growing issue in all mobile networks. Field technicians and engineers need an efficient PIM test solution to quickly correct PIM-based problems and maintain network quality.
BTS System Line Sweep And PIM Testing
Line sweep testing is more important than ever and emerging passive intermodulation (PIM) testing requirements have lifted the bar even higher. This ultimately means the contractors, cell technicians, and performance engineers must work closely together to achieve the required quality of service. This article examines the basics of both line sweeping and PIM testing, how they work together, and why we need to perform these tests to a high standard.
VNA Dynamic Range And Linearity Accuracy
As Vector Network Analyzer (VNA) dynamic range requirements become more demanding, it becomes more important to better understand how receiver non-linear characteristics affect VNA calibrations and measurement accuracy. By identifying the problems and improving the understanding of receiver behavior while pushing the limits of dynamic range performance, one can better understand how to properly configure the system for maximum dynamic range while minimizing measurement uncertainty. This article describes the practical aspects of configuring a VNA system for maximum dynamic range while limiting measurement uncertainty...
