1. Introduction

With a typical range of less than 10 meters, wireless personal area networks(WPANs) have become the popular choice for hands-free access to mobile handsets as well as linking desktop peripherals and personal devices, such as PDAs and smartphones.
The next-generation of WPANs that are in development aim to significantly boost performance, increasing data rates, for example, in order to accommodate streaming video.For these next-generation the WPANs, the specification of note will be throughput, power consumption, and interference.
Characterized by low power consumption and high throughput,which is unaffected by nearby wirless systems operating in band, Ultra Wideband (UWB) technology looks to be a good fit for the next generation WPAN.
The development of a new technology for the consumer market brings in multiple concerns. Those behind the technology must decide whether to make and sell products themselves or whether to align with other companies so that they may produce similar and complementary products. Neither of these strategies ,however, guarantees that the technology will be adopted by consumers.If similar technologies already exist in the marketplace, consumers may be hesitant to adopt the new.
Ultra wideband technology is also not immune to these problems. Firstly , there is still unsolved problems among different parties who want to make their own technology the standard technology for UWB. Secondly, there is a strong threat from other standards which is being sought to be applied for this same short distance purpose. There is also a design challenge to meet the strict requirements set aside by regulatory bodies.
On this blog, in section 2, the two main UWB technology is discussed, also the advantages and applications of UWB is presented. In section 3, we will take a look at the key players in the technology (UWB Technology). In section 4, the struggle to adopt standard for UWB is discussed along with the current status of the Technology. These two section (section 3 and 4 ) gives clear picture of the institutional environment and one way in which a technology can be a "standard".

In section 5, first, requirements for next-generation WPAN is given, followed by a comparison of the two rivals (UWB and 802.11n) for this next-generation WPAN. This section emphasizes on why UWB technology is a better technology compared to 802.11n standard, which is WLAN standard but being considered to be applied for WPAN.
In section 6, current and future challenges to UWB Technology is discussed. Here the challenges are classified in to three and considered one by one. In section 7, the current standing of UWB technology and its future forecasts are discussed. Here recent research results from independent research groups are used. These last two sections (section 6 & 7) will clearly give ideas on the probable success of the technology (the standard).
