Benchmarking Services

Today's extremely competitive wireless market place is experiencing smart phone growth and new network generations driving an increasingly complex mobile broadband services ecosystem. A key competitive lead for any operator is to have a intense understanding of how the end-user perceives their Quality of Experience (QoE), which greatly impacts their overall satisfaction vis-a-vis competition. Benchmarking Services provides this QoE insight to wireless carriers by delivering business intelligence to maximise customer satisfaction to reduce churn, increase ARPU and increase ROI of CapEx and OpEx.

  • End-to-end comparison and understanding of service quality of Voice, data, messaging and video vis-à-vis competition
  • Quality of Service (QoS) monitoring focuses on the end user experience of the service, and allows mobile network operators to react to what effectively subjective quality degradations by investigating the technical cause of the problem in time-correlated data collected during the drive test. Drive centrally manage usage and information dissemination across the entire engineering organization

  • Voice Reports - Voice quality is benchmarked using Mean Opinion Score (MOS) for audio and call quality. Voice reports also contain network information such as call statistics, receiver power and converge
  • Data Reports - Data stream quality is benchmarked using upload and download speed as well as internet connection speed. Analysis of the data quality (Voice Mean Opinion Score (MOS) for VOIP or Video Stream with Mean Opinion Score (MOS). These reports also include information like bit error rates, throughput, and latency
  • Scanner Reports - Scanner reports contain strictly network strength measurements like signal strength and signal-to-noise ratio

Radio Network Optimisation

PYRO RF Optimisation Services guarantee a thorough optimisation of the network and an improvement of network performance within the customer defined constraints. We determine areas for improvement and specify the required input data - measurements, network configuration data and other data about the technology used in the network, analyse the data and determine the changes needed to optimize the network performance.

PYRO optimisation services includes a split of the radio network optimisation process in five sub process

PYRO provides network audit services to its clients, which are telecom service providers or telecom vendors to have a complete knowledge about the implemented systems in the field. This could be physical site audit, where checks are made on the antenna height, antenna type, azimuths, tilt, transmit frequency etc, which broadly fall under the hardware network audit. Under the Radio quality network audit tasks like drive test are used to identify black spots in coverage, quality. Frequency plan analysis helps to check the carrier to interference ratio and the critical areas/regions with high interference resulting in bad voice quality. Cell/BSC/RNC parameter analysis checks for incorrect parameters and values that degrade the QOS to the customer.
