This document summarizes the status of UWB regulations worldwide and proposes considerations for UWB channelization. It reviews available UWB frequency bands and restrictions in regulations from countries like the US, EU, Japan, China and Korea. While the US allows the largest bandwidth from 3.1-10.6 GHz, other countries limit bandwidth and require techniques like DAA. The document proposes localizing UWB channelization to maximize bandwidth within each region's regulations. This would allow higher transmission power and range by fully utilizing the available spectrum.

UWB Regulation Status


USA is the first country that allowed the UWB spectrum from 3.1 to 10.6 GHz at a maximum PSD of -41.3 dBm/MHz in 2002.
While following to the USAs UWB regulations, other countries assigned smaller UWB spectrum and impelled various restrictions to mitigate interference into existing wireless systems. Although UWB regulations were already published in EU, Japan, Korea, etc., update or modification are still in process.

Discussion on UWB Band Usage


Except USA, UWB low band is not or will not be free in other regulations. LDC or DAA are or will be impelled at UWB low band.
LDC will greatly restrict the available communication period while DAA will add significant burden for implementation. UWB high band is free in all regulations while the available band changes in different regulations. The common free band is only 1.25 GHz (7.25 8.5 GHz).

Discussion On UWB Bandwidth


As the maximum PSD is fixed at -41.3 dBm/MHz, a larger bandwidth will allow more transmission power.
Because a big concern at UWB high band is the transmission range, it will be better to maximally use the available bandwidth. The maximum bandwidth is only 1.25 GHz (7.25-8.5 GHz) if we want to implement a common device worldwide. A practical solution is to localize the channelization to maximally take the advantage of bandwidth.
