LTE eNodeB PHY and Protocol Stack

Azcom Technology offers a carrier-grade LTE PHY software package conforming to 3GPP 36.104 and 36.141 and a complete Protocol Stack suite enabling the creation of C-RAN and Small Cell solutins, both FDD and TDD.

Azcom Technology offers a carrier-grade LTE PHY software package conforming to 3GPP 36.104 and 36.141, and a complete Protocol Stack suite enabling the creation of C-RAN and Small Cell solutions, both FDD and TDD.

The LTE PHY software implements a modular, scalable architecture that fully exploits the Texas Instruments® Keystone II System on Chip technology. A flexible design and the standard interfaces (FAPI, CPRI) allow easy porting and integration with customer owned software components. We also offer proprietary solutions in areas such as advanced receivers.

The Protocol Stack control and data planes are optimized to meet the 3GPP LTE performance requirements in terms of throughput, latency and data processing. The O&M plane includes a proprietary agent for flexible configuration and fully customizable Radio Resource Management (RRM) for UL Control signalling resource configuration, link adaptation and UL/DL power control. Clearly defined APIs accelerate building of application extensions, like operator-specific MAC scheduler, RRM and SON modules.

Azcom LTE eNodeB software stacks are field-deployable. Rigorous testing, from module testing to system integration testing, coupled with interop testing with commercial UEs and Evolved Packet Core (EPC) ensures high software quality and reliable performance.

The LTE PHY and Protocol Stack software is available as a standalone package as well as pre-integrated with the Azcom C-RAN and Small Cell platforms.

LTE EPC Software

Azcom’s LTE Evolved Packet Core (EPC) software features a flexible and scalable architecture. The Linux-based software runs on Intel x86 architectures, ranging from small system-on-module (SOM) to large servers and Linux virtual machines (VMs). Various EPC components, viz. Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW) and local Home Subscriber Server (HSS) can be distributed across physical and virtual resources. This makes the EPC easy to deploy, configure and manage, locally and remotely.

Customizable solutions built around the Azcom EPC include closed isolated private networks with private USIMs and public networks in remote locations with public UEs. A mixed scenario with access to both private and public networks is also supported with both Home Routed Traffic (HRT) and Local Break Out (LBO).
