Abstract: Example methods and systems for using radio frequency (RF) signals with different beam widths for purposes of balloon-to-balloon communication are described. One example method includes determining a vertical angle between a first balloon and a second balloon, if the vertical angle is below a threshold angle, communicating with the second balloon using a narrow beam RF signal from a communication system of the first balloon, and if the vertical angle is not below the threshold angle, communicating with the second balloon using a wide beam RF signal from the communication system of the first balloon.
