Company introduction
Who we are and what we do: 
FLSEMI is a deep-tech engineering firm specializing in highly resilient wireless infrastructure and advanced semiconductor integration. We develop mission-critical, massive IoT networks driven by 5G DECT NR+ and self-powered Bluetooth NLC/Mesh technologies. 

What makes us unique:
We develop mission-critical, massive IoT networks driven by 5G DECT NR+ and self-powered Bluetooth Mesh technologies. What sets us apart is our profound mastery of custom MAC/PHY layer implementations—such as FTDMA architectures with microsecond-level sub-slot precision—paired with our proprietary WLCSP System-in-Package hardware.  By integrating energy-harvesting capabilities, we eliminate the operational "battery trap," delivering highly scalable, zero-maintenance infrastructure capable of supporting extreme node densities. 

Working with Nordic Semiconductor:
We deeply integrate Nordic Semiconductor's advanced silicon, specifically the nRF9151, nRF9131, and nRF5340 platforms. Utilizing the Zephyr RTOS and Nordic's highly flexible PHY APIs, we precisely tune low-level radio parameters to deploy our robust, ultra-low-latency protocol stacks directly onto Nordic’s industry-leading, low-power architectures. 

Which projects we focus on:
We focus on large-scale, quality-driven projects by delivering highly structured, turnkey hardware and protocol solutions for both the US and global markets. Our deployments are purpose-built for mission-critical applications, specifically targeting commercial lighting infrastructure, semiconductor foundry automation, defense and government networks, and wide-area environmental monitoring. 

Solutions

FLSEMI ER0S Heterogeneous Gateway: Our flagship ER0S Gateway deeply integrates Nordic's multi-protocol portfolios, serving as a core PoE/IPv6 bridge between zero-maintenance endpoint sensors and large-scale facility management networks.
Dual-Radio HW (nRF5340 & nRF9151: The nRF5340 SoC (with an external FEM) maximizes link budgets for our self-powered Bluetooth NLC switches. Simultaneously, the nRF9151 SiP drives our 5G DECT NR+ backbone,delivering an ultra-reliable backhaul supporting >1M nodes/km² and over 2km LOS coverage. (https://www.flsemi.us/solutions).
Zephyr & NCS Utilization: Built entirely on Zephyr RTOS, we utilize Nordic's PHY APIs for custom DECT NR+ MAC/PHY configurations (e.g., FTDMA sub-slot scheduling). The nRF5340's TCP/IP stack handles MQTT/Modbus TCP bridging, while the nRF9151 manages environmental sensor data reporting via DECT NR+ RACH uplinks.
Turn-Key System Delivery: Combining Nordic silicon with our custom PoE hardware, we deliver complete, battery-free sensing and control infrastructure, feeding seamless data pipelines directly into industrial automation dashboards and building management systems.  

UN Sustainable Development Goals

FLSEMI’s Commitment to UN Sustainable Development Goals (SDGs):

Sustainability is hardcoded into FLSEMI’s engineering philosophy. Our core technological roadmap is strategically aligned with the UN SDGs, specifically focusing on eliminating toxic e-waste and building resilient, energy-efficient infrastructures.

• SDG 12 (Responsible Consumption and Production): Our most significant contribution is the mission to eliminate the "Battery Trap" in massive IoT deployments. By deeply integrating energy-harvesting technologies (e.g., kinetic and solar) with Nordic's ultra-low-power SoCs, our commercialized Bluetooth NLC mechanical switches operate entirely battery-free. This directly reduces the environmental footprint and chemical waste associated with billions of disposable batteries in smart buildings.
• SDG 9 (Industry, Innovation, and Infrastructure) & SDG 11 (Sustainable Cities and Communities): Our deployment of the ER0S Heterogeneous Gateway and 5G DECT NR+ infrastructure provides resilient, low-latency connectivity for mission-critical applications. Relevant projects include our wide-area environmental/water quality monitoring systems and large-scale semiconductor foundry automation networks, which optimize resource utilization and ensure sustainable industrial operations.
• SDG 7 (Affordable and Clean Energy): Through our turn-key smart commercial lighting infrastructure, we enable facility managers to significantly reduce power consumption via precise, automated control matrices driven by our microsecond-level sub-slot communication technology.
