Technologies are generally described for methods and systems effective to determine a location of a communication device. In some examples, a method may include generating a request for a response from the communication device. The method may also include broadcasting the request over a cellular network. The method may also include receiving the response from the communication device at three or more antennas. The method may also include determining respective signal strengths of the response. The method may also include determining a location of the communication device based on the respective signal strengths. The method may also include analyzing a memory based on the location of the device to identify content. The method may also include sending the content to the communication device.
