Ultra-Wideband: A Wireless Renaissance in the Making

Overview Ultra-wideband is a wireless technology that transmits an extremely low power signal over a wide swath of radio spectrum, achieving data rates as high as 114 Mbps today. Unlike conventional radio systems that operate within a relatively narrow bandwidth, i.e. Bluetooth, IEEE 802.11a/b/g, etc., ultra-wideband operates across a wide range of frequency spectrums by transmitting a series of very narrow and low power pulses. The combination of broader spectrum, lower power, and pulsed data means that ultra-wideband causes less interference than conventional narrowband radio solutions, and delivers wire-like performance in an indoor wireless environment.

Radioactive: Bluetooth - survival of the fastest

The term 'ultra-wide band' was first coined by the US Department of Defence in 1989 which was using it for ground-penetrating radar. This increases the signal's range by reducing interference. The US Federal Communications Commission (FCC...

Peter Cochrane's Blog: Aerial bombardment

Once the desired antenna propagation characteristics have been achieved, then it is usual that some closely located system causes interference on one kind or another. Strange as it might seem, a wire loop antenna has a mirrored alternative - a...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
