To achieve greater scalability, more capacity and longer-reach distances, MNOs across the globe are overhauling the traditional coaxial-based systems on their cell towers with fiber-optic cabling carrying CPRI protocol data.

The star of the show may be the delivery of data services—but the cash cow for operators continues to be the delivery of high-quality voice services. It’s easy for customers to switch to other carriers and take their budget for wireless services with them, therefore, carriers must meet that same expectation levels for the quality of experience of voice calls delivered over traditional networks, and apply it to the delivery of voice over LTE (VoLTE) calls.

Many operators are in the process of evaluating and/or deploying VoLTE as this IP-based service promises to leverage the greater capacity of LTE to deliver high-quality voice and video conferencing, among other services. Voice and SMS services may be considered the cavemen of mobile applications by some, but they still represent cash cows for operators. That’s why it’s critical that the deployment of this long awaited technology is not impacted by poor quality of service (QoS) which would jeopardize the revenue-generating power of high-definition voice.

Despite advances in modulation formats and equipment management systems offered with monitoring tools, faults, issues, delays and errors still occur all too frequently in wavelength-division multiplexing (WDM) networks. When this happens, the optical spectrum analyzer (OSA) is a tool of choice for identifying the issue, and helping to fix it.

Webinar of the Week Blog Series | VoLTE has been in the news a lot lately, but not for the right reasons. The headlines have been dominated by stories of repeated delays in tier-1 operators’ VoLTE launches. But how could this possibly be? Based on our interactions with tier-1 mobile network operators (MNOs) and network equipment manufacturers (NEMs), we have come to the conclusion that the industry is hugely underestimating the complexity involved in deploying VoLTE services.
