Brief Overview
Step 1: Send test signal to desired
radio.
Step 2: RX radio sends back reply signal. Friends measure this
signal strength.
Step 3: TX radio sends out
message. Friends not in range
transmit noise.

System Requirements
Battery life of at least 12 hours Receive and transmit Operate while walking Operate up to 300 meters.
• Receive signal with 95% success rate. Voice Transmission Bandwidth Maintain secure communications
• Less than 10% interception rate Handheld and less than 2lbs.

MDR Demo
The goal for MDR will be to demonstrate measurement of receive signal and transmitting noise.
Step 1: Send test signal to desired radio.
Step 2: RX radio sends back reply signal.
Friends measure this signal strength.
Step 3: TX radio sends out message. Friends not in range transmit
noise.
