Hi there,
I have Samsung Galaxy S4 and each time I am connected to EDGE network, my speakers on my stereo player will keep on rattling until I switch off the connection, Why do the speakers rattle? 3G doesen't produce the rattling, How can I solve this since most of the time the network available around my residence is EDGE?
Hi !
What you hear is communication relay terminal with GSM. Basically, the network interrogates the phone network and the latter responds, indicating that it is active. From this communication automatic GSM operator can extract important data, eg. Physical location of the mobile phone. This is performed by calculating response times against giving three or more relays (cell) GSM. Can be extracted temporary encryption keys (some GSM networks use encryption keys Sesin), covering several phone calls (somewhat similar session key sites used by email servers), while other networks change encryption keys (Ki, Kc) on each new call.
You can't solve this problem, you'll have to turn off the speakers or start using Wi-fi, 3G, 4G connection.
