4G LTE Cellular Communications Testbed

Statement of Work (SOW) 4G LTE Cellular Communications Testbed

1 Background

Fourth Generation (4G) Long Term Evolution (LTE) cellular communication technologies allow users to dramatically extend communications capabilities where limited or no communications infrastructure exists. The Naval Research

Laboratory (NRL) is investigating 4G LTE technologies for possible future deployment on US Naval platforms.

1.1 Scope

NRL is seeking to procure a turn-key, deployable, 4G LTE cellular communications testbed to allow our engineers to evaluate the suitability of different LTE cellular communication network topologies in a given deployment environment. The testbed is defined as the combination of a deployable 4G LTE cellular network (also known as a self-contained network in a box), engineering support equipment, and mobile devices. The testbed will be used to simulate multiple commercial deployments (ie rural, suburban, and/or urban), be operated using cables in the lab, and be operated wirelessly in the field. As this will be a limited use network, the capacity to support 100 subscribers and 20 simultaneous users will suffice. The Contractor will engineer, document, deliver, setup, and test the system, and provide training, at NRL in Washington, DC.
