AirScope

AirScope_small_square

AirScope is a software radio LTE air interface analyzer. It provides real-time over-the-air decoding capabilities for network analysis using standard PC and general purpose SDR frontends. AirScope captures the DL signal of an LTE network, decodes the PDCCH channel for all active users in the cell and provides cell-wide and per-user statistics on UL/DL utilization, modulation formats, transferred bytes, etc.

AirScope is available under commercial license. For more information, see our data sheet.

Current Features:

  • LTE Release 15 compliant
  • FDD and TDD configuration
  • Tested bandwidths: 1.4, 3, 5 and 10 and 20 MHz
  • Supported modes: TM1, TM2, TM3 and TM4
  • Real-time PDCCH, PDSCH and PHICH decoding
  • Hex-dump of all captured SIB and Paging messages
  • Cell analytics: number of active users, throughput, time/frequency utilization, average MCS, etc.
  • Signal quality measurements: RSRQ, RSRP, SINR, RSSI, CFO

User Interfaces:

  • Detailed log system ready for post-processing: including PDCCH information (CCE, L, DCI Format, etc.), UL/DL user grants information (MCS, PRB allocation, TBS, RV, MIMO mode, etc.)
  • MAC layer wireshark packet capture
  • Command-line trace metrics
  • Detailed input configuration file

Hardware:

AirScope currently supports Ettus Research USRP, Epiq Solutions Sidekiq and Nuand bladeRF front-ends.
