UWB and Radio
The selected baselines are two optional PHYs consisting of a UWB Pulse Radio ( operating in unlicensed UWB spectrum ) and a Chirp Spread Spectrum ( operating in unlicensed 2. 4 GHz spectrum ).
UWB is a general term for a new type of radio communication using pulses of energy which spread emitted Radio Frequency energy over 500 MHz + of spectrum or exceeding 20 % fractional bandwidth within the frequency range of 3. 1 GHz to 10. 6 GHz as defined by the FCC ruling issued for UWB in Feb. 2002.

UWB and is
Here a single cycle, or transient wave, is used similar to UWB communications, see List of UWB channels.
Ultra-wideband ( UWB ) is another modulation technique that accomplishes the same purpose, based on transmitting short duration pulses.
Ultra-wideband ( also known as UWB, ultra-wide band and ultraband ) is a radio technology pioneered by Robert A. Scholtz and others which may be used at a very low energy level for short-range, high-bandwidth communications using a large portion of the radio spectrum.
A significant difference between conventional radio transmissions and UWB is that conventional systems transmit information by varying the power level, frequency, and / or phase of a sinusoidal wave.
Such a pulse-based UWB method ( using bursts of pulses ) is the basis of the IEEE 802. 15. 3a draft standard and working group, which has proposed UWB as an alternative PHY layer.
A valuable aspect of UWB technology is the ability for a UWB radio system to determine the " time of flight " of the transmission at various frequencies.
Another feature of pulse-based UWB is that the pulses are very short ( less than 60 cm for a 500 MHz-wide pulse, less than 23 cm for a 1. 3 GHz-bandwidth pulse ), so most signal reflections do not overlap the original pulse and the multipath fading of narrowband signals does not exist.
When stealth is required, some UWB formats ( mainly pulse-based ) may be made to appear like a slight rise in background noise to any receiver unaware of the signal ’ s complex pattern.
It also affects UWB transmissions, but according to the Shannon-Hartley theorem and the variety of geometries applying to various frequencies the ability to compensate is enhanced.
Since UWB has almost impulse-like channel response, a combination of multiple antenna techniques is preferable as well.
Due to the short duration of UWB pulses, it is easier to engineer high data rates ; data rate may be exchanged for range by aggregating pulse energy per data bit ( with integration or coding techniques ).
UWB is used for real-time location systems ; its precision capabilities and low power make it well-suited for radio-frequency-sensitive environments, such as hospitals.
Another feature of UWB is its short broadcast time.
The UWB PHY is allocated frequencies in three ranges: below 1 GHz, between 3 and 5 GHz, and between 6 and 10 GHz.
Ultra-wideband ( UWB ) refers to any radio transmission that uses a very large bandwidth – which is the same as saying it uses very rapid changes in modulation.
Although there is no set bandwidth value that qualifies a signal as " UWB ", systems using bandwidths greater than a sizable portion of the center frequency ( typically about ten percent, or so ) are most often called " UWB " systems.
The main disadvantage of pulse-based UWB SAR is that the transmitting and receiving front-end electronics are difficult to design for high-power applications.
( Although it is true that UWB provides a notable gain in channel capacity over a narrow band signal because of the relationship of bandwidth in the Shannon – Hartley theorem and because the low receive duty cycle receives less noise, increasing the signal-to-noise ratio, there is still a notable disparity in link budget because conventional radar might be several orders of magnitude more powerful than a typical pulse-based radar.
