One important aspect of our universe is that one cannot get something from nothing; there is always a price to pay. In this article we show that every bit of information is limited by a quantum unit.  Since we are communicating within a temporal subspace, this unit can be equivalently described as a quantum limited subspace (QLS), as imposed by the Heisenberg Principle. We show that communication can be exploited within and outside the QLS. The size of a QLS is determined by carrier signal bandwidth; that is narrower the bandwidth the larger the size of the QLS. By manipulating the size of a QLS, more efficient information transmission strategies can be developed.  Examples for inside and outside QLS communication are given. Extension to relativistic communication has also been demonstrated.  We remark that, a new era of communication is anticipated to immerge and it will change our way in communicating, observation and computing, we used to use forever! © Anita Publication.
