 with differing strengths. The script takes in arguments by specifying a type of
 signal to broadcast followed by the corresponding parameters for that signal.
 This script requires the user to specify at least 1 signal in order to operate.
-In order to broadcast from file, use the '-f' flag and specify the path to the
-file as well as a factor which corresponds to a db-gain on the specific signal.
-A general db-gain can also be specified by using the '-g' flag to amplify the
-combined signal.
+The script currently supports 4 types of signals:
+1) It can broadcast a signal from a raw data file which is generated by a file
+  source in GNURadio and by the script included in this
+  project.
+2) Periodic - Generates a single sine wave at a specified offset from the
+  center frequency and should show up as a spike in the fourier transform.
+3) Wifi - Mimics a wifi signal. The type-specific signals like this require
+  that a config file be specified. The parameters of this signal can be
+  generated using It also requires a signal profile stored
+  in a .npy file.
+4) Bluetooth - Mimics a Bluetooth signal. See Wifi for description.

+UDP Test Tool
+The UDP Test tool is a connection testing tool that is similar to iperf. This
+tool has been created partially due to limitations in iperf. This tool is
+designed to test downstream throughput and measures the speed of a connection
+by sending UDP traffic very quickly to a downstream client and measuring the
+packet loss and adjusting the send rate accordingly.
+There are currently some issues with the UDP Test tool. Right now, it is not
+able to show similar rates as iperf (using tcp). UDP should be faster than
+TCP and so presumably the transmit rates of the tool should be higher. Because
+of this it seems that the UDP Test tool is not impacted significantly by
+interference. A good alternative is to use iperf with the -i and -t options.
