Coverage & antenna engineering
Low-power embedded systems
A complete radio product
A radio link is more than a module.
Range, battery life, data rate, enclosure, antenna placement, interference, firmware, network behavior, and regulation all influence one another.
We engineer those constraints together, reducing the gap between a promising bench prototype and a wireless product that performs predictably in the field.

Practical questions
RF and LoRaWAN engineering, without hand-offs.
Can Sosteco develop a complete custom LoRaWAN device?
Yes. Engagements can include system architecture, electronics and PCB, antenna integration, embedded firmware, sensors, enclosure constraints, gateway and cloud interfaces, validation, and production support.
How do you determine whether LoRaWAN is the right technology?
We compare range, payload, latency, energy, topology, ownership, operating cost, regulatory limits, and deployment risk against alternatives such as cellular IoT, BLE, Wi-Fi, or proprietary sub-GHz radio.
How is coverage validated?
We begin with a defensible link budget and propagation assumptions, then validate with representative hardware, antenna placement, packet statistics, field measurements, and worst-case operating conditions.
Can you improve an existing RF or LoRaWAN product?
Yes. We can investigate range, battery life, packet loss, antenna detuning, RF layout, firmware behavior, sensor integration, manufacturability, and field reliability without requiring a complete redesign.
