IoT Product Development

We build connected sensor nodes and wireless edge gateways, implementing robust networking architectures that stream telemetry data securely to your IoT cloud platforms.

IoT Development Failures

IoT field deployments are vulnerable to specific connectivity and hardware problems:

Connectivity Dropout: Unstable cellular or LoRa links without data recovery.
Battery Depletion: Constant searching for signal drains field nodes in days.
Security Breaches: Plaintext MQTT telemetry streams open to sniffing.
Scale Jitter: Inability to update thousands of devices in the field.

Thinkfinity Resilient Designs

We build our telemetry nodes with multiple layers of fail-safe protection:

Offline Data Logging: Local Flash memory buffer keeps data during link failure.
Adaptive Power Sleep: Nodes adjust signal searching rates to conserve power.
MbedTLS Encryption: Hardware-accelerated SSL/TLS secure payloads.
FOTA Framework: Secure incremental firmware-over-the-air upgrades.

FAQ

IoT Development FAQs

Which radio standard is best: LoRaWAN or NB-IoT? +

It depends on infrastructure. LoRaWAN is ideal if you want to deploy your own private gateway network in rural areas or factories, requiring no recurring telco SIM card fees. NB-IoT/LTE-M is better if you have ready cell coverage and want nodes to connect directly without a gateway.

How do you ensure IoT security? +

We implement security on multiple levels: secure bootloader verifying cryptographic signatures, TLS 1.2/1.3 encryption on cellular lines, unique credential tokens stored inside cryptographic hardware elements, and disabled debug interfaces (JTAG/SWD) on production units.
