Frequency Agile LTE Connection

$15,000 USD

Challenge overview

The Seeker is looking for a method to operate private LTE cellular systems using non-owned radio spectrum on a secondary basis. These private cellular systems would be used to support First Responder emergency events on a temporary basis.

This Theoretical Challenge requires only a written proposal.


For many emergency events, the First Responders would like to set up a private LTE cellular system to support data and voice communications at the scene. However, the First Responder organizations do not own any cellular radio spectrum. Instead, they would like to find a way to use radio spectrum owned by others on a temporary, non-interfering basis. In order to allow this, the First Responder’s private LTE system must be frequency agile, that is, it must first sense activity on the desired spectrum and then adjust the private LTE spectrum usage to avoid interfering with the spectrum owner’s services.

A typical use of this private LTE system would be to establish an LTE cellular network at the scene of a forest fire. Generally, there is limited cellular coverage for at the forward front of the wildfire. However, the command center is often located at a location closer to populated areas so that fire fighter’s private cellular system must avoid interfering with the primary spectrum owner’s cellular system.


Another use of the system would be to set up a private cellular system in order to do video surveillance on a possible crime scene. In this case, the data transferred by the cellular system and the fact that the surveillance has even been set up is extremely sensitive. As such, the First Responder community does not want to use commercial cellular systems. The private LTE cellular system must be frequency agile so as to not interfere with the existing cellular networks.

For legal purposes, the Solver can assume that the Seeker has permission/authority to use the radio spectrum ahead of time on a secondary basis. The Solver can assume that they have access to the radio spectrum and just need to connect as requested in the Challenge, using a portion of the radio spectrum that is not in use and switching to another portion of the spectrum if needed. The Solver does not have to worry about any protocol of asking permission to use the radio spectrum. 

Receipt of a Challenge award is contingent upon theoretical evaluation of the submitted Solutions by the Seeker.

Note: The award for Theoretical solutions is $15,000.

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution. However, the Seeker will be willing to consider a licensing agreement for a partial award if exclusive IP cannot be transferred by the Solver.

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on January 2, 2019.

Late submissions will not be considered.
