Helix Smart Radio
1625-2500 MHz - Six Government Bands

Driven by the needs of UAVs and UGVs, the Defense Innovation Unit sponsored the customization of the Smart Radio platform. The Helix Smart Radio leverages our patented Mesh Rider® technology

Six Federal Bands in a Single Radio

Helix operates on six software selectable bands (M1-M6) within 1625-2510 MHz. These bands remove a large operational complexity for DoD deployments around the world. The Helix radio incorporates advanced filters, one for each band to provide maximum protection against the interference.

mini OEM Form Factor

Minimal size and weight was a driving consideration during the Helix design phase. The mini OEM form factor consists of two boards (Baseband and RF boards) that can be mounted in a variety of configurations within the chassis to meet different space and thermal management considerations.


  • RF Board: 51 x 46 x 5 mm
  • Baseband Board: 28 x 47 x 6.5 mm
  • Combined weight: as low as 25 grams

Powered by Mesh Rider

Like all Smart Radios, Helix is powered by Doodle Labs’ patented Mesh Rider technology. Many features have been designed specifically for the unmanned vehicle use case, such as optimized channels to carry command & control and video traffic. Range extension and swarming are facilitated by a dynamic mesh. 

Connect the Entire Operation

The Helix Smart Radio is an addition to the widely deployed Smart Radio platform to connect men and machines.

Core Radio for Leading Ecosystems

Helix Smart Radio is a core radio in the Blue sUAS Architecture and is verified to be compatible with a number of sUAS components, such as QGroundControl, Auterion and UXV Technologies.

Overview of the technical features of the Helix Smart Radio. Please consult datasheets in the Technical Library for details.

Frequency Range

Federal M1-M6 Bands
Helix operates on six bands (M1-M6) within 1625-2510 MHz, which provides global coverage so systems can be deployed without requiring multiple SKUs. This frequency range removes a large operational complexity for government customers who have deployments around the world. Moreover, license free 2.4 GHz band is also covered to further increase the global coverage.

M1 Band = 1625~1725 MHz

M2 Band = 17800~1850 MHz

M5 Band = 2025~2110 MHz

M3 Band = 2200~2290 MHz

M4 Band = 2310~2390 MHz

M6 Band = 2400~2510 MHz
