Let us suppose two cells A and B communicating with one another, I want to know how do cells ensure time synchronization while communicating. For instance, let us assume cell A sends a sequence '110'. Where '1' corresponds to dissemination of certain number of molecules, while '0' corresponds to no transmission of molecules. Now, cell B detects first '1', and then because of some delay in the reception of another '1', the sequence now received is '101'. I want to know that how do cells ensure time synchronization?
Or because of very small distances over communication range, there is no need of it?
