It is common to think that impulse radio ultra band signals (IR-UWB) in communication systems can carry the information at very high rates. But each impulse of the signal can carry just one bit of information. In radio networks it is necessary to add destination address to every information unit. The best way for each subscriber is use series of impulses mutually orthogonal to the rest of series in the network. But the orthogonality means long multi impulse series with low density of impulses to make time domain space transparent. As a result, data transmission rates become much less than expected. To increase data rates in radio networks modulation of each impulse by amplitude, duration and polarity in the series is proposed. Examples of transmitter and receiver are presented. As a result, informative loading on signals increases manifold, compensating or neutralizing losses, related to the transmission of symbols by impulse sequences.
