A method for user equipment to improve position information of one or more communication devices including obtaining map information about positions of the one or more communication devices, determining radio channel information about the one or more communication devices by analyzing a radio channel, and generating a node map having improved position information of the one or more communication devices using the map information and the radio channel information.

A synchronization server creates an augmented radio listener experience by providing additional information, especially visual information, over a concurrent, parallel data connection to a user device during the radio broadcast. The additional information is synchronized to the radio broadcast item then playing, based on an event message received by the synchronization server from the radio station equipment. The synchronization server can implement real-time interactions between connected radio listeners and a disk jockey dashboard of the radio station. The synchronization server optionally can personalize advertisement content for transmission to user devices based on user profile information and audience criteria provided by the advertiser.

According to an embodiment of the present disclosure, a method of controlling an apparatus for providing data broadcasting includes receiving additional data of a radio data system, displaying the received additional data of the radio data system, storing the received additional data of the radio data system, monitoring a communication status, and transmitting the stored additional data of the radio data system according to the monitored communication status.

According to embodiments, a radio data receiving method includes receiving radio data in a specific frequency band by a vehicle, and displaying information related to the radio data, and in this case, the radio data includes emergency information, the emergency information indicates an event related to a specific location on a road, and the emergency information is received based on a receivable range of the emergency information.

A radio apparatus for a vehicle and a control method thereof. An aspect of the present disclosure provides a method of controlling a vehicle radio apparatus, the method comprising: checking a program title of a program of Internet radio being listened to; searching for a frequency of a first analog radio with the program title, the first analog radio being a radio broadcast transmitted by a radio station; checking an electric field strength of the first analog radio at the frequency; modulating the Internet radio to a second analog radio when the electric field strength is less than a threshold; and transmitting the second analog radio.

A radio system includes an audio device, and a control device operatively connected to the audio device to store a first radio frequency of the audio device as a preset frequency, wherein the control device may be configured to determine whether a second broadcast signal received through a second radio frequency is equal to a first broadcast signal received through the first radio frequency stored in a preset list when the second radio frequency of the audio device is added as the preset frequency, generate the preset list including the first and second radio frequencies when the first broadcast signal is different from the second broadcast signal, and generate the preset list including the first or second radio frequency when the first and second broadcast signals are broadcast signals of a same radio broadcast.

Disclosed is an electronic device including a communication module, a processor and a memory that stores instructions. The instructions, when executed, cause the processor to receive a first signal from a first external electronic device through the communication module while a communication connection to at least one second external electronic device is being established, select a specified number of third external electronic devices or less from among the first external electronic device and the at least one second external electronic device based on the first signal, and transmit data to or receive data from the selected third external electronic devices through established communication connections to the selected third external electronic devices. The third external electronic devices are selected in order of having a weak signal intensity or a greater distance from the electronic device from among the first external electronic device and the at least one second external electronic device.
