Emulated Long Term Evolution (LTE) Analysis Environment

Description:

TECHNOLOGY AREA(S): Info Systems 

OBJECTIVE: Develop an emulation system capable of deploying a full Long Term Evolution (LTE) Fifth Generation (5G) architecture, including all subcomponents, utilizing open source software, into self-contained commodity personal computer hardware. Utilize open source shared code components to construct LTE software and standardized interfaces with an emulated physical layer in Extendable Mobile Ad-hoc Network Emulator (EMANE) to provide a low cost capability to rapidly conduct research and experimentation on utilizing LTE for tactical comms and the performance of tactical sensors and other mission command systems under varying scenario configurations and conditions. 

DESCRIPTION: As various U.S. Army units and program offices consider utilizing cellular Long Term Evolution (LTE) capabilities on the battlefield, there is a need to research and study the possible use cases and potential performance in order to feed the planning of the proposed LTE solution. A lab based, open source LTE emulation will provide the ability to deploy and full LTE ecosystem including but not limited to base station eNodeB, Enhanced Packet Core (EPC) and User Equipment (UE) within a cost effective set of commodity PC hardware. The LTE emulation, when integrated with other tactical network emulations, will allow analysis of the performance of various mission command applications and intelligence sensors and software while utilizing a tactical LTE solution. Additionally, the system will allow study of techniques for integrating LTE infrastructure into the existing tactical comms network architecture including interoperability with other tactical radios and electronic warfare systems. 

PHASE I: Study the full ecosystem of Long Term Evolution (LTE) including eNodeB, Enhanced Packet Core (EPC) and User Equipment (UE) and provide a whitepaper detailing the design of an open source full LTE deployment “in-a-box” including physical layer emulation and upper layer software. The preliminary design must include interfacing UE upper layer software with an emulated physical layer provided by Extendable Mobile Ad-hoc Network Emulator (EMANE) including user and control signaling and data. The design must also include non-proprietary implementations of all the infrastructure components and features of the latest LTE release and the ability to successfully communicate inter and intra-cell. The system must accurately represent all LTE components as defined by the 3rd Generation Partnership Project (3GPP) specification. Considerations for scaling up to multiple eNodeB base stations with hundreds of UEs per base station must be included. 

PHASE II: Implement the design provided in PHASE I by developing a prototype open source Long Term Evolution (LTE) emulation which can be integrated into a larger system of systems emulation. System must allow for instantiating all open source software and tools required to provide a LTE capability on commodity hardware. Implementation must include at least a single Enhanced Packet Core (EPC)/EnodeB and 100 User Equipment (UE) devices. 

PHASE III: Scale production of Long Term Evolution (LTE) emulation to multiple EnodeB/Enhanced Packet Core (EPC) base stations as well and hundreds of User Equipment (UE) devices.
