In one embodiment, a method includes sending, from a client system to a media-player device, an indication that a user is logged into an online social network via an application. The media-player device includes antennas, and power levels of the antennas are set to maximum in response to receiving the indication. An orientation position of the client system with respect to the media-player device is determined based on broadcast signals received from the antennas. At each boundary position of the client system, where each boundary position in range of an antenna, a broadcast signal is received from the antenna. Signal strengths are determined for the received broadcast signals. Instructions to adjust a power level of each of the antennas based on the determined signal strengths are sent to the media-player device. The power levels are adjusted to define a broadcast range based on the orientation and boundary positions. |

1. A method comprising, by a client system of a user of an online social network:
sending, from the client system to a media-player device, an indication that the user is logged into the online social network via a native application associated with the online social network, the client system being within range of at least one of a plurality of antennas of the media-player device, wherein the media-player device sets a power level of each of the plurality of antennas to a maximum power level in response to receiving this indication; determining an orientation position of the client system with respect to the media-player device, wherein the orientation position is determined based on one or more broadcast signals received from one or more of the plurality of antennas; receiving, from the media-player device, at each of a plurality of boundary positions of the client system with respect to the media-player device, at least one broadcast signal from at least one antenna of the plurality of antennas, wherein the respective boundary position is in range of the at least one antenna; determining, for each received broadcast signal, a signal strength of the received broadcast signal, wherein the determined signal strength is associated with the respective boundary position at which the broadcast signal was received; and sending, from the client system to the media-player device, instructions to adjust a power level of each of the plurality of antennas based on the determined signal strengths, the power levels being adjusted to define a range of broadcast of the plurality of antennas based on the orientation position and the boundary positions of the client system. |
