Samdale’s PEGASUS
Samdale’s PEGASUS product is the latest offering that comprises a family of systems for real-time monitoring and optimization of digital radio networks. For a description of the PEGASUS product, click here.
The system combines real-time monitoring information from a network of fixed and roaming probes with powerful “on-the-fly” event processing and analysis. The system stores all event data from all probes in an industry standard SQL database at one or more PEGASUS servers, with the data being automatically replicated.
The PEGASUS Probes are self-configuring and operate autonomously once power is applied to the unit. They will automatically buffer up to 180 days of log data locally, automatically transferring information available to PEGASUS servers whenever a network connection is present, which can be via LAN, Wi-Fi, 3G/GPRS, etc.
The fixed probes are designed to monitor the service in a particular area or from a specific base station, whereas the roaming probes are designed to be fitted to vehicles and gather coverage and performance data on the move. The PEGASUS Roaming probes are designed to be easily retro-fitted to existing terminal installations for use with operational vehicles which by virtue of the fact they are patrolling an area anyway, provide “free” coverage and performance data for the area without the need to undertake expensive dedicated drive testing.
Critical problems are alerted to nominated users immediately by SMS, e-mail etc., while the real-time probe viewer and web-based analysis tools provide system operators with powerful tools to analyse trends and identify and isolate service-affecting problems.
The range of service metrics monitored includes:
- Received Signal Strength (RSSI)
- Signal Quality (Downlink BER)
- Signal Quality (Uplink & Downlink PESQ)
- Path Delay
- Frequency Re-Use/Interference
- Channel Acquisition Failures
- Uplink Access Failures
- Receive Path Problems
- Call Setup Success & Completion Stats
- Call Setup Times
- Call Setup Failures
- Cell Reselection/Handover Stats
- Fragmentation Failures
- Cell Handover Failures
- Dropped Calls
- Broadcast Parameter Discrepancies
- Broadcast Neighbour Discrepancies
