Key Differentiators

Feature Richness

  • Carrier Aggregation (CA)
    • Same Carrier Scheduling
    • Cross Carrier Scheduling
    • PCell Change
    • SCell Activation/Deactivation
    • 8x8 MIMO in all serving cells
  • All downlink transmission modes (TM1-TM9)
  • Multiple Cells, Sectors and Carrier Aggregates
  • FDD and TDD in a single executable
  • VoLTE
    • QoS/QCI aware scheduler
    • Semi-Persistent Scheduling (SPS)
    • Robust Header Compression (RoHC) including Sooktha RoHC library (no third party libraries are required)
    • TTI Bundling

High Portablilty

  • Developed on the Sooktha SP platform – can be executed on RT Linux or hardware API directly
  • FAPI compliant PHY interface module – integrated with multiple third party PHY implementations
  • Hardware accelerator interface (SHA 256, SNOW 3G, AES 128, IP Networking) – integrated with hardware accelerators on SoC (Software implementations are available for initial integration)
  • Multiple SoC Architectures – Multicore, Hardware Threads, Master-Slave
  • Multiple System Architectures – SoC Based (Small Cells), Discrete Hardware Modules (Micro/Macro Cells), Distributed Nodes (for Virtualized Access Networks)

Extensive Diagnostics

  • Message tracing on all Control Service Access Points (C-SAPs)
  • MAC TB logging in Wireshark format for protocol messages
  • FAPI Message logging in Wireshark format
  • Statistics at different layers
  • Extensive Software logs – different levels and the log level is configurable at module level

Flexible OAM/SON Options

  • Support for TR-181 and TR-196 models for management via TR69
  • Provisions to integrate SNMP v3 based interface to EMS
  • Support for SON features such as PCI selection, ANR, Interference Management, and Mobility Optimization – both distributed and centralized

Extensive Test & Measurement Support

  • Full 3GPP ASP support (TS 36.523)
  • Support for overriding standard compliant state machines (for adversarial testing)
  • Extreme radio conditions, conditions under which the UE would have been released very quickly in a normal base station but which are a key feature in Test & Measurement equipment
