Aspects provided herein provide methods, systems, and a non-transitory computer storage media storing computer-useable instructions for dynamic allocation of internet of things (IoT) device communications. The method begins with determining an amount of unallocated spectrum in a communications channel used by one or more devices attached to a node. Next, it is determined that the IoT device has requested an amount of spectrum from the node that is less than the amount of unallocated spectrum. At least a portion of the amount of unallocated spectrum is dynamically allocated to the IoT device.
