Hello I am an electrical engineer who has rich experience in electrical engineering and RF communication fields. I think this project is very suitable for me and I can make the communication range longer. If we use LoRA WAN communication we can usually do RF communication upto 20km. I hope we can discuss the project in more detail via chat or call. Kind regards alexander

this project is very closely connected to what I have been doing for the last 6 years. I've worked on over 45 projects that include professional R&D of hardware. They have included general schematics & PCB design in various areas, including, but not limited to: microcontroller design, analogue systems, digital communications. I have also worked on programming STM & Arduino microcontrollers. I am sorry to tell that this kind of project cannot be made with this budget. If you are interested in the price range quoted at this proposal, please contact me for more info. Thank you!

Dear customer, depending of the data amount, have you considered satellital communication? I can provide you with two portable, twin units that never fail in the communication. Should you be interested please contact me, I own an enterprise entirely dedicated to this. Please do not care for the bid automatically generated numbers. Once I know your needs, we can revise the offer. Best regards, and thank you for your attention.
