I need a focused research effort that looks at satellite-communication antennas from three angles at once: maximising signal strength and quality, mapping frequency-band usage, and refining antenna design and materials. The outcome should give me clear, data-backed guidance I can hand straight to my hardware team. Scope You will survey current literature and patents, run electromagnetic simulations (HFSS, CST, FEKO or similar), and translate the findings into practical design recommendations. Emphasis is on L-, S- or Ku-band performance; however, if your analysis uncovers a better-suited band, flag it and justify the choice. Deliverables • Concise comparative report (PDF) • Simulation files with setup notes • Performance charts showing gain, VSWR, efficiency and li...

I’m kicking off a multi-phase R&D effort devoted to the design and development of cutting-edge microstrip antennas. The overarching targets are straightforward: boost usable bandwidth while simultaneously lifting signal strength, all without compromising the core advantages of printed technology. Phase by phase, I’ll be iterating from theoretical models through to lab-verified prototypes. You’ll take the lead on concept generation, electromagnetic simulation (HFSS, CST or an equivalent full-wave solver), layout refinement, and hand-over for fabrication. Once hardware comes back, we’ll compare measured S-parameters and radiation patterns against the simulated baseline, fine-tune, and document lessons learned for the next spin. Key deliverables • Simulation...

I'm seeking an engineer to create an intelligent mouse trap focused on monitoring and alerting. The trap should utilize a motion sensor for mouse detection and an actuator to trigger a trap upon detection. Key Requirements: - Motion sensor for detection - Actuator to trigger trap - Notification system for alerts Ideal Skills and Experience: - Experience with sensors and actuators - Knowledge in IoT and notification systems - Background in hardware development and prototyping Please share your relevant experience and approach.

I need a custom ELRS (ExpressLRS) solution for drone control, utilizing an STM microcontroller instead of the original MCU. Key requirements: - Improved range - Enhanced security - Dual band - Mesh networking capabilities Ideal skills and experience: - Proficiency in STM microcontrollers, especially STM32 - Strong background in RF communication and protocols - Experience with drone control systems - Knowledge of security implementations in wireless networks - Familiarity with mesh networking technology Please provide relevant experience in your bids.

I'm looking for a detailed simulation of 5G soft handover in Matlab for research and analysis purposes. Key Requirements: -Simulate system-level handover with integrated PHY and MAC layer modeling in MATLAB -Consider satellite, aerial (e.g., UAV/HAPS), and terrestrial segments within a SAGIN scenario -Support evaluation of handover performance using KPIs such as handover latency, throughput, packet loss, and connection stability Provide comprehensive analysis and visualization of results (e.g., KPI trends, CDFs, outage/interruption time, HO failure rate) Ideal Skills and Experience: - Proficiency in Matlab - Strong understanding of 5G network architecture and handover mechanisms - Experience in network simulation and performance analysis - Ability to present data clearly and concis...

I need a compact, production-ready circuit that brings reliable wireless communication to a new consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long le...

I need an experienced network engineer to spend one full day at a data-center site acting as my hands-on field presence while my remote team drives the configuration. Your focus will be purely physical: racking and mounting Cisco, HP, and Dell switches, servers, and firewalls; dressing both power and copper/fiber runs neatly; then powering everything up so we can reach it remotely via the console or management ports. Once devices are live, you’ll run quick-hit checks—basic pings, uplink and printer connectivity, plus a test print from each printer—to be sure the new gear and the existing workstations all join the network without surprises. I will supply a clear, step-by-step build guide and remain online to answer questions in real time. Deliverables: • All specifi...

I have a draft research proposal that needs a careful editorial pass before submission. The document is complete in terms of content, but I want it to read smoothly, follow academic conventions, and convince reviewers of its merit. The proposal is related to machine learning, security, and wireless. So, you must be in the area. What I expect from you: • Line-by-line editing for clarity, concision, and scholarly tone • Consistent formatting of headings, citations, tables, and figures to match standard style guides (APA or Chicago—whichever best fits the context you identify) • Light re-organization where paragraphs or sections could flow better • A tracked-changes file plus a clean, ready-to-submit version I’m open to suggestions on strengthen...

I need an experienced low voltage technician to install a data network in a commercial building. ON SITE in USA The installation will include: - Ethernet Cabling - Network Switches - Patch Panels Ideal skills and experience: - Proficiency in low voltage cabling - Experience with commercial data network setups - Knowledge of networking equipment and installation Please provide relevant experience in your bid.

I have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate. Stability and reliability are my chief concerns; speed is acceptable once the board reconnects. The task is straightforward: go through the existing codebase, spot whatever is undermining the connection logic, and supply clear, working fixes. Serial logs, event callbacks, power-saving modes, and DHCP handling are all fair game—whatever it takes to stop the frequent disconnects. Deliverables • Annotated version of my original source showing every change made • A concise technical note explaining the root cause and the remedy (1–2 pages) • A quick reconnection stress-test script or steps I can replicate to p...

We are looking for an experienced developer to build a small Linux utility that communicates with a U.2 NVMe SSD over SMBus (NVMe-MI). The project involves low-level hardware and software work, not application development.

I’m looking for an experienced Wireless Network / IoT Engineer to help me design the correct setup for a solar-powered wireless IP camera. We already have the camera and solar panel, but we are struggling to select and combine the correct access point / antenna / network components to make everything work reliably. The task includes: • Recommending the correct access point or wireless bridge • Ensuring compatibility with a solar-powered camera • Advising on power consumption • Verifying range, stability, and bandwidth • Optional: diagram of the final setup No physical installation required, only remote consulting and hardware recommendation.

We are currently looking for freelance Network Engineers in your city to support ongoing onsite requirements for our customers and act as the eyes and hands for the remote configuration team.
