A wireless communication method and system enabling dynamic multi-path data transmission and reception across heterogeneous radio access networks. The method includes selecting between sequential, concurrent, or redundant multipath transmission strategies based on real-time measurements of link quality parameters, including signal-to-interference-plus-noise ratio (SINR), reference signal received power (RSRP), delay, and spectrum availability. The system further enables adaptive transmission power control, modulation scheme selection, and carrier configuration based on physical layer feedback, minimizing interference and optimizing spectral efficiency. Peer-to-peer communication between terminals is supported without base station mediation, reducing RAN load. Multi-base station connectivity is enabled, allowing terminals to simultaneously transmit through multiple nodes and aggregate at the core network. The architecture supports real-time topology control, dynamic link adaptation, and transmission parameter adjustment based on physical-layer constraints.

A virtual fiber communication system includes a central cloud server that obtains telemetry information from a plurality of network nodes in a backhaul network. The network nodes include hybrid analog-digital repeater devices. The server also obtains frequency-spectrum availability metadata and custom-defined spectrum-access parameters from spectrum-owner nodes. The server causes each hybrid analog-digital repeater to form dual analog data links on a first and a second polarization with at least one neighboring hybrid analog-digital repeater. Using the telemetry information, the frequency-spectrum availability metadata, and the custom-defined spectrum-access parameters, the server detects spectrum-availability variations across the network nodes, determines routing paths for a first type of UEs designated as premium users, generates control signals that assign data streams to rented or leased spectrum frequencies, and selects one of the routing paths to deliver the data streams to the premium UEs while satisfying the custom-defined spectrum-access parameters.

The US Department of Defense is rapidly moving to incorporate 5G in its networking capabilities. Incorporating 5G should be done in secure manner, especially in contested environments. Indeed, 5G UEs are typically located at the tactical edge, while the 5G Core Network is located safely away from the operational theater. The 5G base stations may be near the edge or further back, but come with their own operational issues in a battle scenario. By utilizing the N3IWF / TNGF functionality, but replacing the Access Point with a secure tactical network, UEs can securely reach back to the 5G Core Network with greatly reduced overhead. The UE's communication remains robust even in the presence of reduced spectrum availability and / or intentional jamming by an enemy actor by using secure tactical networks and radios in a contested environment.

This disclosure is directed to allocation of one or more radio bands to a user equipment (UE) for establishing a radio link with a radio node (e.g., eNodeB or gNodeB). The radio bands may include a shared band, such as citizens band radio service (CBRS), a primary licensed band, such as the B66 band, and / or an unlicensed band, such as B46 band. A radio communications system may consider a variety of parameters associated with the distance of a UE from a radio node, signal strength of a signal from the UE, the services requested by the UE, and / or spectral availability of the each of the radio bands to determine which radio band(s) to allocate to the UE. In some cases, the radio band allocated to a UE may be dynamically changed by the radio communications system as conditions related to the UE and / or the mobile network change.

A virtual fiber communication system includes a central cloud server that obtains telemetry information from a plurality of network nodes of a wireless backhaul mesh network. The central cloud server obtains frequency spectrum availability metadata and custom-defined access parameters from spectrum owner nodes. The central cloud server detects one or more radio frequencies that are unused or underutilized in different geographical areas under coverage by the wireless backhaul mesh network. The central cloud server allocates the detected one or more radio frequencies that are unused or underutilized to one or more portions of the wireless backhaul mesh network based on a successful authorization from the one or more spectrum owner nodes and the custom-defined access parameters, where each of the one or more portions of the wireless backhaul mesh network includes a different subset of network nodes of the plurality of network nodes.
