WiPry-Combo for RF Engineers
You can measure rise and fall time, duty cycle and peak power, and examine 2.4GHz ISM band used by WiFi, Bluetooth, and other networks. This tool could be quite useful to cellular communication planners, RF engineers, WiFi technicians, and geeks in general. Too bad it does not support Android devices.
