That's impossible! 1Km range with a FPC antenna on an arm band? No!!! Don't you realize that obstacles such as buildings and foliage can also affect the transmission range! I have worked extensively with LoRa modules (plenty) and I have achieved transmission distances up to 1Km but using external magnetic mount omni directional antenna and the module was transmitting at maximum power! In your application the module will never transmit at maximum power because it is wearable electronics and battery operated. Maybe U need to consider this! Thanks,
