I would like to see your description first, but initially, I can propose to make a device with a range about 1000-1500 m that work at 2.4 GHz (no license is required) and has very low power consumption in sleep mode. Longer distance also possible if necessary. I can propose a final solution when I'll know your requirements for amplitude and frequency range and signal's discretization frequency. I have more than 20 years of experience in programming and electronics.

Hello Sir, its an easy task for me. most of my project are based on RF transceiver, relay switching, amplification of signals and conversion of signals one protocol to other. I have 4 years experience in PCB designing in EAGLE( single multilayer and flex) following are some examples of my work 1. ESP12E wifi + relay board + humidity&temp sensor Smart module 2. ESP12S wifi + relay board home automation board. 3. ESP12E wifi + RC522 RFID + BUCk converter module. 4. atmega328au + hm11(BLE)+ relays car actuator module. 5. atmega328au + nrf24l01 + relays smart switch module. 6. atmega328au + mpr121 capacitive touch smart remote. 7. amega328au + LCD display + hc06(later hm10) + amplifier + strain gauge water mapping module. 8. atmega328au + hm10(BLE) + gyroscope + reed sensor + battery charger smart skateboard module 9. Arduino Uno clone. I will provide you all necessary files ( code, gerber, smd-coordinate, BOM, Eagle(.brd& .sch) ). please, see my portfolio for more sample of my work. or initiate chat more detail discussion on your project. thanks.

Hello Sir I can do it perfectly I built many devices like that before I need to know that: *The distance between the devices *Relay types (DC or AC) *Relay quantity *Communication methods between them "we will specific it depending on the area and distance " *the transmit data type is it a(sensors data or notification or gsm sms or.......) I'll manufacture it and test it here then send to your by DHL Services I hope to have more discuss with you about that Feel free to contact me at any time ,I'll be available for next 2 hours I have proficiency in following software tools: Electrical circuit design Arduino IDE pcb design microcontroller programming ,interface plc programming scada system design Siemens S7 programming Electrical circuit simulation thermal control system building circuit (low energy control) bluetooth NodeMCU programming IOT (internet of things) Mplab(x) IDE micro C IDE PCB manufacturing Thanks Mohamed

hi, i think this can be done using a microcontroller ( like raspberry pi), which connects to an amplifier. it can receive signals for example using the GPIO or the serial port, and output them to an amplifier. i'll be interested seeing the PDF showing the device. i'm a signal processing engineer, i have a lot of experience especially in the raspberry pi, ranging from stereo vision, to image compression, robotics and more. i would like to be considered for the project.
