A flexible 4G solution

WiMAX has been deployed across the globe and remains a formidable force in the 4G domain, especially in niche markets. Network Equipment Manufacturers (NEMs) can leverage its flexible architecture for customizable deployment in different scenarios—from in-building and low-density rural networks, to high and very-high density urban networks. Aricent has been a pioneer in WiMAX since its inception, and we have helped our clients create products for some of the first commercial WiMAX networks. Our industry-proven protocol stacks and software frameworks offer very high price-to-performance ratios, and they have been tested for interoperability with equipment from major NEMs.

Aricent WiMAX Protocol Stacks and Software Frameworks

WiMAX Integrated Gateway (WING)

WING is an integrated software solution consisting of a Profile-C ASN Gateway, an Authentication, Authorization and Accounting (AAA) Server, and Home Agent components, all co-located on a single network node which supports both nomadic and mobile subscribers. This framework can scale to support 20,000 subscribers and serve the needs of rural, Tier 3 and enterprise deployments.


eASN is a complete Profile-C ASN gateway software framework with control plane, data plane and management plane functionalities. eASN can scale to support up to 300,000 subscribers and serve the needs of rural, Tier 3 and medium-to-high density deployments.


Our BS framework is a Release-6-compliant control plane software framework for base stations of all form factors, including macro, pico, femto and Profile-C.


  • Scalability: Can scale to meet the requirements of low to very high and all-terrain density deployment scenarios.
  • Standards Compliance: Compliant with Network Working Group (NWG) R1.2 and R1.5 specifications.
  • High Availability: Support for carrier-grade high-availability features that ensure session continuity is maintained across system switchover/failover.
  • Platform Independence: Executable on any Linux-based Commercial Off the Shelf (COTS) hardware including RMS, ATCA and uTCA platforms.
  • Proven Interoperability: Strong ecosystem and close strategic partnerships ensure interoperability with access and core equipment from multiple leading third-party vendors.
  • Reduced Complexity: Network layout and device management complexity simplified with WING.


2G continues to be an important communication technology especially in emerging economies that haven’t yet upgraded to other technologies. General Packet Radio Service (GPRS) can be leveraged to facilitate data services in the 2G networks and elevate it to 2.5G, and the Gb stack provides an interface between Base Station Subsystem (BSS) and the Serving GPRS support node (SGSN).

GPRS Gb Interface Stack

The GPRS Gb Interface Stack from Aricent has been developed for both the SGSN (Serving GPRS Support Node) and BSS/PCU (Packet Control Unit) nodes. The BSS-Gb protocol stack can be used to upgrade existing GSM BSS equipment and provide GPRS-based packet data services. On the other hand, SGSN vendors can use the SGSN-Gb protocol stack to build their equipment. This support will help GSM networks provide packet-data-based services and applications like mobile Internet, mobile email access and wireless VPNs. Both the stacks are equally attractive for use by test and measurement tool vendors.

Operation and Management Support

The GPRS Gb interface stack provides extensive operation and management support as well as debugging assistance through:

  • Run-time control of capacity and configuration parameters
  • Extensive statistics collection (API protocol, internal events and error statistics)
  • Error and alarm reporting
  • Multi-level tracing supports (detailed and brief traces)


  • Validated against test suites
  • Flexible packaging options: Gb on BSS/PCU, Gb on SGSN, Gb on SGSN and BSS/PCU
  • Available over standard Frame Relay
  • Support for SIGTRAN SCTP/TCP/UDP
  • Portable onto a wide range of operating environments (generic and proprietary)
  • Modular and easy to customize
  • Well-defined and documented interfaces (APIs) to the stack components
