Radio Communication Repeater

My client have a radio comunication with hopping frequency working in 800 MHz Range, that only work in 50 meter radius and need to expand to 500 meter.

what need to design is a repater that can receive hopping frequency and re-transmit with higher Tx power to the original receiver.

it can be made into 2 repeater device

A. a Transmitter that receive original hopping frequency and re-transmit to different freq (hopping is better)

B. a Receiver that receive the different freq transmitted by unit A, and retransmit into original hopping frequency to the original transmitter

if possible to make into single unit will be better

The Output Needed :
1. Schematic Diagram
2. Electronic Diagram
3. PCB Design
4. Bill of Material

Kĩ năng: Arduino, Thiết kế vi mạch, Kĩ thuật điện, Điện tử, Vi điều khiển
