Wireless & connectivity firmware
Products that stay connected — on battery, at range, and out in the field.
Connectivity is where embedded products fail quietly: a link that works on the bench but drops inside the enclosure, a radio that drains the battery, a pairing flow nobody can finish. We make the connection something no one has to think about — the right radio for the job, proven for range and battery life in the field, with the resilience habits of our defence radio work.
01 / What it solves
Range, battery life, data rate and cost traded off on real hardware, so you back the part that actually fits the product.
BLE, Wi-Fi, LoRaWAN, cellular and Thread/Matter built into your firmware and RTOS, so devices just connect.
Self-healing device-to-device networks that keep a site connected with no router or tower in reach.
Pairing flows people can actually finish, with per-device keys in a secure element, rotation and revocation.
02 / Stack
Industry-standard, boring in the good way: tools with a future, that the next engineer will know too.
Short range
Bluetooth Low Energy
Nordic, ESP32 and Silicon Labs stacks; GATT, mesh, audio
Wi-Fi
Station and AP modes, provisioning, low-power Wi-Fi 6
Thread / Zigbee / Matter
Smart-building and home meshes with Matter commissioning
NFC & UWB
Tap-to-pair and precise ranging
Long range
LoRa / LoRaWAN
Kilometre-scale, battery-powered telemetry
Cellular (LTE-M, NB-IoT, Cat-1)
Nationwide coverage with eSIM and power saving modes
Sub-GHz proprietary
Custom links where the standards do not fit
SDR & anti-jam waveforms
Frequency-hopping and resilient links from our Miltech work
Protocols & security
MQTT / CoAP
Lightweight publish-subscribe and REST for constrained devices
TLS / DTLS with hardware keys
Mutual authentication backed by a secure element
Mesh routing
Self-healing multi-hop networks between devices
Protocol buffers / CBOR
Compact, versioned payloads over slow links
03 / Approach
Link budgets calculated, then verified in the field with real antennas and enclosures.
Adaptive data rates, retries, store-and-forward and mesh so a bad day for the radio is not a bad day for the product.
Provisioning, key storage and rotation designed in — never a shared default key.
The radio is the biggest consumer; we schedule it around the battery, not the other way round.
04 / Standards
We adhere to industry standards and proven methods on every project — they are what makes the estimate hold.
05 / Infrastructure
Good questions
Straight answers to what buyers ask before they start.
Yes, where interoperability matters. WNC builds BLE, Wi-Fi, Thread/Matter, LoRaWAN and cellular firmware, with secure provisioning and pre-compliance checks including radio cybersecurity under EN 18031.
