Release date- 27082019 - Volkswagen showcases future use cases with UWB equipped concept car: higher levels of theft protection, safety, convenience.
Some warehouses could benefit from technology such as UWB. Unlike traditional bar code scanning with handhelds, today's edge technologies can pull in data without human intervention.
However, there have been few studies on the relationship between guanxi and UWB, and there is still no consensus in the conclusions of the researchers.
For this reason, implementation of a filtering function into UWB systems is crucial to overcome interference issues; however, it is preferable not to introduce additional size into the UWB system circuitry, because miniaturization of today's wireless communication systems is strongly needed.
MIMO technology has caught our attention as it significantly increased channel capacity without any additional power or bandwidth [5, 6]; however, we have found the mutual coupling between the UWB antenna elements which are very large to get installed on a confined space with the multiple antenna elements.
However, UWB system design faces many challenges, the serious one of which is interference with other coexisting narrow band communication systems such as WLAN, WiMAX, and ITU X-band satellite communication systems operating in 3.3-3.7 GHz, 5.15-5.825 GHz, and 8.025-8.4 GHz, respectively.
Moreover, the 1-13 GHz spectrum band is also covering the 3.1-10.6 GHz UWB channel which has been adopted for UWB outdoor communication applications at tropical areas.
With the expansions in antenna technology for UWB applications, the interference challenges in the frequency bands are the major ones to be dealt with.
Inability of Narrow Band and Spread Spectrum to fulfill modern wireless sensor network requirements, research turned towards Ultra Wideband (UWB).
As the unlicensed use of ultra-wideband (UWB: 3.1-10.6 GHz) frequency spectrum for indoor and handheld wireless communications is released in 2002 (L.
