The Design of a Spatial Diversity Model to Mitigate Narrowband and Broadband Interference in DSSS Ad Hoc Networks

Overview Spatial diversity has been gaining significant momentum in cellular systems due to its ability to improve radio links in mobile wireless channels. Techniques of spatial diversity have been expanded to build foundations for advanced antenna array technology, to increase capacity in mobile wireless communication systems due to radiation patterns that direct energy only in the intended direction, thereby greatly reducing interference. Similar benefits may be gained in DSSS ad hoc networks, though work in this area has been limited. To exploit spatial processing in future ad hoc networks, accurate array designs that embed spatial characteristics of the channel and radiation patterns are necessary to quantify the performance benefits.

Peter Cochrane's Uncommon Sense: Wireless everything

What is really invisible is the radiation of energy across a broad range of frequencies. We have principally avoided interference by allocating specific frequencies of operations separated in the same way that the different radio channels on your...

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?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
