gnal has a bandwidth that exceeds the lesser of 500 MHz or 20% of the center frequency, there is an authorized unlicensed use of the frequency range starting from 3.1 GHz and up to 10.6GHz, also the emission limit is -41.3 dBm/MHz. This technology uses the Impulse Ratio (IR) method for its transmission; the rate is different for radar and imaging purposes to the communication purposes. The rate of impulses for radar and imaging is in the range of 1 to 100 mega pulses per second. The communication rate can be in a range of 1 to 2 giga pulses per second.

This diagram shows how much faster Ultra Wide Band technology is over any existing current technologies also it provides a high level of mobility which is important for a mobile devices it is intended for. The advantage of UWB over traditional radio transmissions is that traditional way would be to modulate the frequency and phase of the signal as well as power, of a sinusoidal wave. However UWB transmits impulse at a specific time, there fore it allows pulse position modulation and time modulation.

Among the advantages of UWB that helps to prevent multi path propagation. It gives the possibility of the system to establish the time for an impulse to travel from the transmitter to the receiver in the direct path. The other advantage of UWB IR system is the short length of pulses does not allow them to overlap so the multipath fading is not an issue in this case. On the other hand in a system with high pulse rate there can be inter-path interference, it can be eliminated by error correction coding at the receiver.

UWB can be combined with multiple antenna technology that doesn’t only allow increase in transmission speed but increases the reliability of the channel, there are a number of solutions that can increase the transmission speed over the regular SISO (single-input single-output); Technologies like multiple-input and multiple-output (MIMO) allows reaching gigabits per second range of transmission speed.
