    I am in need of a seasoned developer with proficiency in working with RF modules and LoRa technology, or similar, to create a system that can compute the distance between two RF modules. I am seeking a skilled developer to create a system that calculates the distance between two RF modules using LoRa technology or a similar module. The system should operate within the 2.4 GHz or sub-GHz frequency bands. Required precision of the measured distance in outdoor environment is 10 meters (can be 100 meters in the first version). If you have expertise in RF communications and embedded software development, I encourage you to bid on this project.

The effects of slot placement, position, and configuration on the waveguide play a critical role in optimizing antenna radiation at a given frequency. The objective of this project is to design a Slotted Waveguide Array (SWA) in the X Band [8 GHz-12 GHz] with a centre frequency of operation set at 10 GHz. The general goal is to optimize the to performance for example at least achieve a reflection coefficient |S11| <-10 dB which is a good indicator for impedance matching. To achieve this goal you need to consider all the above parameters in order to achieve the required outcome, remember that is a minimum required but further optimisation...

I already did the mathematical model and I know the behaviour of the model and I need the RL model to have the same behavior. when the maximum cluster size is too small (1mm *1mm), the sensor nodes select a higher BW option ( e.g. 100 GHz) that would consume less energy compared to a smaller BW option. Still, it can only be used for short distances, up to D_max=11 mm. When the D_max increases, selecting a higher BW will not be optimal because the achieved channel rate is less than the required data rate.

    Antenna Design: Start with a well-designed PCB antenna layout. Common designs for BLE antennas include meandered monopoles or inverted F-antennas. The design should be based on the desired operating frequency (usually around 2.4 GHz for BLE) and the available PCB Dimensions: Ensure that the physical dimensions of the antenna (length, width, and spacing) match the design specifications, which are typically calculated based on the wavelength at the operating Plane: Maintain a good ground plane beneath the antenna. A solid ground plane helps with the antenna's radiation pattern and impedance Matching: Use a network analyzer or an impedance matching network (like a matching circuit) to adjust the antenna's impedance to match the desired value (usually

    Hello, i need to do a small microprocessor project. I think its not very hard. 1. Microprocessor - Reed Sensor if seat belt is fastened - Distance Sensor( is somebody sitting on the seat? ) - 2,4 Ghz Transmitter - Maybe with a battery or accupack? Without wire If somebody sitting on the seat and the belt is not fastened its sending a signal to the main unit. 1. Main Unit - 2,4 Ghz Receiver - Small speaker - Hardwired Doing a Noise when seatbelt noch fastened. I need a completely finished project with a prototype and the possibility to order the finished devices in a case somewhere online. It dont need to look beautiful. Only do its work. But with ready Case Design The Battery should last minimum for2 months The finished product needs to be ordered at Eurocircuts.
