UWB is dead for sure. People start saying UWB is dead since 3, 4 years ago.
If you know the history, you would know how much Intel has bet on UWB. Now y
ou read the news that Intel is not doing it any more, what else do you expec
t to revive UWB?
Sure, Intel has a lot of money. It moved on to WiMAX with lost of money. I a
m sure you heard many people nowadays saying that WiMAX is dead. From my per
sonal point of view, WiMAX will not be totally dead. But it definitely c

hnology is not so important in my personal opinion. It's the market that dic

发帖数: 71 | 14 我从来不袅UWB. UWB一直在叫高速率低功耗。但速率和11n差不多，功耗在1w左右（一
点也不低）。由于其RF带宽高，analog的成本也高。性能价格都不好，不死才怪。

发帖数: 192 | 21 Without careful designs, yes, 60 GHz works mainly in LOS. However, SiBEAM
chips already demoed successfully with the LOS blocked. They have some
careful designs I believe. Still, 60 GHz would be mainly for inside a room.
Recent news is that Tzero, WiQuest and Focus Enhancments closed down, "with
Artimi merging with Staccato. Texas Instruments early on quit chip
development and dispersed its design team and, while Intel dropped its own
chip development in favor of what emerges from startups such
