Wide Band Series SemiWiki

How can ultra-wideband done right do more with less energy

In the previous part, we discussed how the time-frequency duality can be used to reduce the latency. When you compress in time a wireless transmission, you reduce the time it takes to hop from a transmitter to a receiver. Another very interesting capability enabled by the… Read More

The Story of Ultra WideBand Part 4

How Ultra-wideband aligns with 5G’s premise

In part 3, we discussed the time-frequency duality or how time and bandwidth are interchangeable. If one wants to compress in time a wireless transmission, more frequency bandwidth is needed. This property can be used to increase the accuracy of ranging, as we saw in part 3. Another very… Read More

The Story of Ultra WideBand SemiWiki

In Part 2, we discussed the second false-start of Ultra-WideBand (UWB) leveraging over-engineered orthogonal frequency-division multiplexing (OFDM) transceivers, launching at the dawn of the great recession and surpassed by a new generation of Wi-Fi transceivers. These circumstances signed the end of the proposed applications… Read More

The Story of Ultrawideband SemiWiki 1

Over-engineered to perfection, outmaneuvered by Wi-Fi
In Part 1 of this series, we recounted the birth of wideband radio at the turn of the 20th century, and how superheterodyne radio killed wideband radios for messaging after 1920. But RADAR kept wideband research alive through World War 2 and the Cold War. Indeed, the story of… Read More
