Wireless Jobs

I need a complete IoT gateway hub that brings LTE (4G), Wi-Fi, Bluetooth, Zigbee and sub-GHz RF into a single, reliable unit for remote monitoring and alerting of smart-home devices. The goal is straightforward: gather data from a variety of in-home sensors and actuators, push it to the cloud over cellular when Wi-Fi is unavailable, and relay actionable alerts back to the user in real time. Here is what I expect: • Hardware design that accommodates the five radios with proper coexistence planning, power management and antenna layout. • Embedded firmware that can automatically select the best back-haul (LTE or Wi-Fi), maintain secure connections and expose a clean API or MQTT/HTTP interface for the smart-home layer. Also with bluetooth, zigbee and rf. • Delive...

Namaste, mujhe ek Low-Cost Wireless Audio Receiver/Box Prototype banwana hai. Main pehle ek chhota working prototype banwakar uski testing karna chahta hoon. Agar prototype sahi tarike se kaam karta hai, to aage isi design ke bahut saare units banwane hain. 1. Hamara Basic Concept Hum ek aisa chhota aur kam lagat wala wireless receiver box/module banana chahte hain, jo ek main transmitter/master unit se wireless audio signal receive kare aur us signal ko speaker/amplifier tak pahunchaye. Hamara uddeshya hai ki gharon, dukaanon aur anya locations par lage chhote speaker boxes ko har jagah alag se internet/Wi-Fi se connect karne ki zarurat na pade. Main system kuch is tarah rahega: Main/Master Unit → Wireless Signal → Receiver Box → Amplifier/Speaker Isi concept par hume...

I’m putting together a straightforward location-tracking system for loads of non-perishable goods that move through warehouses, trucks, and rail cars. The core requirement is real-time position updates from departure to storage, with automatic alerts if a device signals potential theft. The hardware can be either single-use—so the receiver never has to return or recharge the tag—or a reusable unit that we can redeploy after each trip. I’ll need your help scoping both variants and producing an estimated cost per device for each. What I expect from you • A concise technical proposal outlining the recommended tracker form factor, network technology (e.g., GSM, LTE-M, NB-IoT, LoRaWAN), and back-end platform or API you plan to leverage. • A table or brie...

ESP32 Sonar Data Streaming to Android Phone – 300–400m Direct Wi-Fi Link, No Repeater I am looking for an experienced embedded/RF developer to build a reliable wireless communication system for a fishing boat sonar. CURRENT SETUP On the boat: - Sonar - Existing sonar driver - ESP32 On shore: - Android phone WHAT I NEED I want the following architecture: DRIVER → ESP32 → Wi-Fi AP + external antenna → 300–400m → Android phone → APK The Android phone must connect DIRECTLY to the boat. STRICT REQUIREMENTS - 350–450 meters real-world range - Direct boat → phone connection - NO repeater - NO router/access point on shore - NO additional radio receiver on shore - NO internet connection required - Android phone must receive the data di...

My goal is to get our small-to-mid-size office network running smoothly, securely, and with room to scale. The work is purely technical support focused on full network setup and ongoing maintenance. Scope of the job The environment includes routers, switches, several wireless access points, and a mixed fleet of laptops, VoIP phones, and IoT devices. I need someone to: • Plan and configure the wired backbone (VLANs, trunking, QoS) • Optimise WiFi coverage, assign channels, and fine-tune roaming settings • Harden the entire network with firewall rules, WPA3, and up-to-date firmware Most of the hardware is already on-site and powered up; it just isn’t talking to each other reliably. You’ll start with a quick audit, document the current layout, propose any...

We are a team of Electrical Power Engineering students working on our senior graduation project. We need an experienced Electrical Power Engineer to provide technical guidance and engineering support for designing, simulating, and building a physical prototype. The project focuses on detecting power-quality disturbances (Voltage Unbalance and Harmonics) affecting a three-phase induction motor, diagnosing the disturbance, and applying automatic corrective actions in a closed-loop system. Key areas include: 1. Hardware Prototype Development: Guidance on architecture, component selection, electrical design, sensing/isolation, protection, wiring, testing, and troubleshooting for components like three-phase induction motors, VFDs, ESP32-based data acquisition systems, harmonic filters, capaci...
