The band-pass filter can filter out clutter signal than 2.3-2.5GHZ, so it
can improve the signal to noise ratio. As before, ZIGBEE amplification of WIFI,
Bluetooth signal, the first signal filter to filter out clutter, and then into
the low noise amplifier for signal amplification, so that it can greatly improve
the reliability of signal transmission, but also can increase the communication
distance.
