By: Sasken Communications Technologies  09-12-2011

Sasken Wireless Protocol Stacks offer customers complete layer 2, layer 3 and layer 4 implementation pre-integrated on our partner’s chipsets. The solution conforms to the latest 3GPP Release 99.

The key value of the Sasken Wireless Protocol Stack solution is its completeness, architectural scalability and flexibility that enables the porting of the stack to new silicon architectures, faster than others in the market. Sasken GSM/GPRS/EDGE/UMTS (dual mode capable) stack solutions are proven implementations – integrated and validated on multiple silicon platforms from different Semiconductor partners. Enriched by years of experience in validation for GCF conformance and its comprehensive in-house beyond-conformance test suite, Sasken Wireless Protocol Stack has been tested and matured across different Networks.

In a world where risk is expensive, time-to-market is a key competitive factor and need to differentiate handsets a necessity for survival, Sasken Wireless Protocol Stacks stand out in four ways:

  • Complete abstraction from changes in silicon/chipsets for quicker integration and carry over maturity
  • Ease and speed of de-bugging
  • Support of latest and differentiating features
  • Support to customers till product launch and beyond comes from a rich tradition of software services

Key Features of the GSM/GPRS/EDGE/UMTS Solution

  • GCF certified on multiple platforms
  • GSM/GPRS/EDGE Quad-band, Class B operation support
  • Multi-slot classes 1 to 12 support
  • GSM/GPRS Coding scheme 1 to 4 support & EDGE MCS 1 to MCS 9
  • Circuit data and packet data support
  • Fax/Modem support
  • Complete AT command set
  • EDGE TYPE 1 and TYPE 2 ARQ implementation
  • Support for simultaneous voice and packet call
  • USAT implementation
  • Dual SIM Support
  • WCDMA support for all Bands - I to X
  • Support for GPS / A-GPS
  • Support for WB-AMR
  • Inter-RAT (GSM/GPRS/WCDMA) Voice and Packet call handover
  • Inter-frequency and inter-RAT measurements support
  • Inter-RAT cell selection/reselection
  • Extremely flexible and optimized debug infrastructure and tools

Key Differentiators

  • Well defined interfaces that enable quick porting of solution onto new silicon architectures carrying over all the existing maturity
  • Proven on both single and dual-core architectures
  • Structured, scalable code that maximise design reuse
  • Lowest memory footprint
  • Low MIPS utilisation
  • Optimised hand-written code

All this resulting in providing our customers with faster time-to-market, lowest TCO, coupled with comprehensive support from design to launch.

Sasken Wireless Modem Services

Sasken’s expertise in Wireless Modem solutions from 1999 has enabled us to provide high quality services with lowest TCO to silicon providers and device manufacturers.

Experience across the product life cycle of wireless modems from requirements identification to deployment is used to provide services in:

  • 3GPP specifications related consultation
  • 3GPP Wireless Protocol Stack and layer 1 development
  • Identification and implementation of 3GPP change requests and feature enhancements
  • Support with integration of Protocol Stack with different hardware platforms and layer 1 solutions
  • Gap analysis and enhancement
  • Performance enhancements and optimization
  • Platform migration
  • Testing in development phases, per-certification, conformance testing and Interoperability Testing
  • Maintenance services and support to customers
  • Offshore or Near-shore Test Lab setup

The success on 3GPP protocol stack and Layer 1 control development helps us to take these best practices for architecting and developing Protocol Stacks of other related communication systems covering Satellite Communication, Air Traffic Management Systems and Broadband Modems.
