Inside the 5G Gateway
Disassembled layer by layer — from the sealed industrial enclosure down to the firmware routing plane.Scroll to disassemble the assembly layer by layer — from the sealed industrial enclosure down to the firmware routing plane.
Modem & Radio Stack
The heatsink lifts to reveal the M.2 5G NR module on its PCIe Gen3 / USB 3.0 carrier. Qualcomm, UniSoC, Fibocom, and MediaTek modules are all supported.
- M.2 KEY-B
- Carrier Aggregation
- U.FL antenna diversity
Firmware & Routing Layer
Custom OpenWrt / ImmortalWrt images expose the AT-command bus and VLAN routing engines for per-site RF tuning and automated failover.
- RSRP / SINR optimisation
- AT command tuning
- NIST 800-88 sanitisation
Two engineering disciplines, one accountable team
Software and hardware are built by the same group — so integration risk, vendor handoff, and finger-pointing are engineered out of the delivery.
Web & API Engineering
Bespoke corporate platforms, custom ERPs, and internal portals built on clean, auditable architecture.
- RESTful API architecture with token auth and rate-limiting
- Laravel, Python, Node.js, Inertia.js, React, Tailwind CSS
- Payment gateway integration and multi-tenant portals
