Abstract: This work deals with development of link budget analyses of   telecommunication wireless links. Our presentation gives more optimistic evaluation of fundamental limits of maximum achievable data rates of such links up to Terabit per second values and presented more correct approach to calculations of a budget by well known Shannon formula if a cryogenically cooled extremely low noise receivers are used for communications. Effect of cryogenic cooling on the wireless link rate has been experimentally proven.

Key words: space telecommunication, low noise receivers, cryogenically cooled receivers, noise temperature, noise figure, THz waves, millimeter wave,  submillimeter wave communications.
