RF architecture and link budgets
Frequency planning, propagation assumptions, receiver sensitivity, spreading factors, duty cycle, interference, capacity, and energy trade-offs.
Sosteco LLC · RF · LoRaWAN · LPWAN
Sosteco LLC develops RF and LoRaWAN products for US teams, from link budget and antenna architecture through custom electronics, embedded firmware, field validation, FCC preparation, and production.
A complete radio product
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.

Where long-range, low-power links matter
Practical questions
Yes. Engagements can include system architecture, electronics and PCB, antenna integration, embedded firmware, sensors, enclosure constraints, gateway and cloud interfaces, validation, and production support.
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.
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.
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.
