Halo beyond-line-of-sight connectivity product

The Halo from Elsight is a beyond-line-of-sight (BLOS) connectivity product for uncrewed aerial, ground and maritime vehicles. It bonds several cellular and other IP networks into a single logical data link, so that command and control, telemetry and video can reach a remote platform without depending on one radio link.

Instead of designating a primary link and a backup that takes over after a failure, the Halo keeps all available networks active at the same time and aggregates them into one virtual channel. Traffic is steered toward the strongest paths in real time, and when one path degrades the others carry the load. For an operator this means that a drop in a single carrier does not interrupt the session. Per-link quality-of-service rules let the integrator give command and control traffic precedence over bulk data such as live video, and the system is not tied to a single carrier or region.

The product is offered in two formats. The OEM module is built into the vehicle and measures 87 mm wide, 69 mm high and 19 mm deep, with a weight of 93 g and an average power consumption of 6.5 W, which keeps the impact on a size, weight and power budget small. The Boxed Halo is a self-contained ruggedized unit measuring 122 x 31 x 117 mm (width, height, depth) and weighing 534 g, intended for forward operating bases, mobile command posts and field teams that need a ready-to-use communications hub.

Integration uses standard Ethernet, USB and serial interfaces, with native MAVLink protocol support and open APIs for connecting the link to ground control software and wider command systems. Firmware updates, monitoring and configuration are handled remotely through a management and insights layer, available cloud-based or on-premises, which also records link ratios, the cause of link changes and per-link performance.

Data security is addressed with a double-VPN architecture. Mission data is split into packets, encrypted with AES-256-CBC and sent through VPN tunnels, so that the compromise of one link does not expose the whole data stream. The maker describes the product as NDAA compliant and lists it on the Blue UAS list.

Typical applications are BLOS and BVLOS operations of UAVs, UGVs and USVs in inspection, public safety, delivery and defense missions, remote operations from a secure location, and multi-asset operations that need a resilient communications foundation over public and private cellular networks.
