SignalPro/ Signal & The Cirrus Platform (December 2021)

Dec 7, 2021

New product build – Release 25030


  • Addition of Studies to Cirrus Engine: The Cirrus Study Engine is continuously optimized and enhanced for the industry. The Current updates include import of all propagation models, equipment types, LTE & 5G studies for RSRP, SS-RSRP, Interference, DL & UL throughput. These studies can be run on large geographical areas with no limitation on transmitters. Ideal for large nationwide FCC submissions, MNO operations and any other RF operation for large studies.
  • Novus Application Enhancement; Novus, our latest product that is directly connected to the cirrus platform. Allowing users to launch their projects to the cloud leveraging the study engine and project consolidation. A user dashboard and exporting capabilities are now available, thus allowing the users to upload any project and view them on a custom dashboard.
  • Neighbor Planning & PCI Enhancements; In the last few releases we have built new enhanced Neighbor and PCI planning for LTE-PRO and 5G. In continuing these efforts other enhancements have been added to the following;
    • Spread-Sheet Editor; Entry for PCI, PSS, SSS and Neighbor Relations are available
    • RF Systems; Addition of PCI and Neighbors to the Transmitter/Base/Hub/Router Site Details. Users are able to add/edit at sector level   
Wireless planning Software
  • Repeater-placement calculations compatible with modulation layers; The Repeater placements have been enhanced to work with active modulation layers. This feature includes the following;
    • To work with all projects that are using just the master-list or with modulation layers or both
    • The revised algorithm will return a faster and the most optimal result.
    • A switch is provide to speedup the calculations when there is fanout.
  • CPE/mobile power; To cater for vendor equipment the CPE & Mobile power have had limitations lifted to cater for very low or very high power requirements
  • Antenna conversion tool enhancement; Enhanced further to convert different Atoll pattern files to .pat files


  • Sector Assignment Channel Planning error; After assigning servers for the CPE’s an error was seen whilst running the study. This is fixed
  • Spreadsheet Editors – Link filtering Error; An error was seen when running a filtering query in the spreadsheet Editors. This is fixed
  • WiMAX Uplink Throughput producing 0 Mbps on every CPE; This was due to the setting that was added to the GUI for for Uplink interference of 0 dBmW which is 1 mW at point of receiver. Default value should be set by user
  • Multipoint Planning Crash; It was found that due to a mix assigned and unassigned CPE the study was crashing, this has now been fixed
  • RAN Node Template Error; It was found that when the PCI value was left blank in the RAN Node, the validation would present an error. This is fixed


  • 30m Global Data Attenuation File; The 30m global world data attenuation file needs to be added to SignalPro if you are using this data. Please contact support for the attenuation file
