Selecting the right dispersion compensation level on coherent links is not an option, not in a competitive landscape where services keep multiplying and expectations for quality of experience keep soaring towards new heights. Paradoxically, the budgets earmarked for capital expenditures (CAPEX) remain just as tight. Your field teams installing, monitoring and troubleshooting high-speed networks have to deal with this given. But what if you were overspending without knowing it?

Single radio voice call continuity (SRVCC) and enhanced SRVCC (eSRVCC) services give subscribers impressive flexibility to seamlessly access VoLTE services across 2G, 3G and LTE networks. However, as more and more VoLTE deployments hit the market, there is an increasing need for network equipment manufacturers (NEMs) and network service providers (NSPs) to better understand and test these complex networks, in conjunction with their SRVCC and eSRVCC services, so as to reduce deployment delays, poor quality of service (QoS) and network failures.

As powerful technologies continue to emerge in the market, such as VoLTE, WebRTC, Small Cells, E-SBCS and more, mobile network operators (MNOs) and network equipment manufacturers (NEMs) are nevertheless facing tremendous challenges in their deployments—often underestimating their complexities, missing out on best practices to optimize the deployments, and struggling to maintain their CAPEX and OPEX targets.

Voice over LTE (VoLTE) is the future of voice communications via wireless networks. It gives mobile operators the upper hand when competing against the OTT players. So why are carriers delaying their VoLTE rollouts? Is it possible to avoid post-deployment service quality impairments and network breakdowns? Read further to get all the answers.

Many optical spectrum analyzer (OSA) users need to decide what type of OSA is required to analyze these signals in the field: traditional grating-based OSAs or a new generation of OSAs? There have been some comments that operators should select the high-resolution OSAs, which provide higher resolution bandwidth (RBW), for optimal analysis. Is this hype really founded?

Voice over LTE (VoLTE) is the talk of the town. Everyone in the industry is rushing to deliver VoLTE and the rich communication services that will tag along. However, many seem to profoundly underestimate the complexity underlying this new technology. VoLTE is not an upgrade of a previous technology–it’s a whole new game when compared to the good ol’ copper wires.
