Doodle Labs has developed and patented a set of technologies underlying the Mesh Rider® family of software-defined, multi-band radios for private and contested-spectrum networks. This summary describes, in plain language, the scope of Doodle Labs’ issued U.S. patents. It is provided for general awareness and to support licensing and collaboration discussions.
Multi-Channel, Multi-Band Configurable RF Front-End Arrangement for Wireless Communication
Subject matter: A reconfigurable RF front-end that places tunable frequency converters in the transmit and receive paths, allowing a conventional limited-band wireless modem to transmit and receive across a wide range of frequencies (on the order of ~100 MHz to 7000 MHz).
Key elements: Multiple transceiver channels, each with transmit and receive sections that use superheterodyne (local-oscillator-based) conversion; per-channel tunable mixer and frequency synthesizer; selectable band filters and power amplifiers; and closed-loop output power control, supporting TDD and FDD operation.
Role: The foundational front-end architecture for the platform.
Configurable Smart Radio Module
Subject matter: Packaging of the front-end architecture as a confurable “smart radio module” with a fixed embedded sub-system and a band-defining, removable RF front end
Key elements: An embedded sub-system (sensors, processor, transceiver); an RF source-select switch that chooses between an internal modem and an external modem as the front end’s input; multi-channel operation within a band; and a swappable front-end element so a module configured for one band can be exchanged for another.
Role: Enables a common module form factor across different frequency band
Advanced Wireless Communication System Incorporating Wideband Frequency
Subject matter: Extension of the frequency-shifting architecture to wideband frequency hopping, where the operating frequency is changed over time across a wide span according to a hopping-sequence map.
Key elements: A hopping-sequence map of local-oscillator frequencies across a wideband range; synchronization options including a separate map-generating network element with GPS, or next-hop information carried in the transmitted frame; support for distinct transmit and receive sequences and per-channel sequences in a MIMO configuration; and receiver-feedback-driven avoidance of degraded frequencies.
Role: Adds frequency-hopping resilience and low probability of intercept to the front-end architecture.
Patent 10,498,371 is the root front-end architecture. Patent 11,611,363 packages that architecture as a swappable module, and Patent 12,261,639 extends it with wideband frequency hopping — both building on the same frequency-shifting foundation. Patent 11,930,430 covers the complementary waveform and protocol layer. Together they describe an integrated approach to software-defined, multi-band, frequency-agile private-network radio.
Doodle Labs makes this portfolio summary avaialble so that organizations developing in adjacent areas are aware of the technology early in their planning. If your work touches multi-band frequency conversion, frequency-hopping front ends, configurable radio modules, or software-defined private-network waveforms, we welcome a conversation about licensing or collaboration.
