On the Impact of Beamforming on Interference in Wireless Mesh Networks

Overview For a wireless mesh network with randomly placed devices, the paper analyzes the impact of beamforming on the statistics of the signal attenuation, interference, and SIR between devices. This paper shows that simple random direction beamforming performs equally well as omni-directional transmission if no MAC layer is present. Optimized beamforming between transmitter-receiver pairs yields a much better SIR than omni-directional antennas. If devices are able to eliminate the strongest interferers, either using a MAC protocol or null steering, both beamforming approaches perform much better than omni-directional transmission, i.e., they allow for a given SIR threshold more concurrent transmissions in the network.

Private bits - the battle to safeguard data through encryption

DES allows both the sender and receiver to use the same key to encrypt and decrypt. One of the simplest DES applications currently used is SSL - secure sockets layer - a protocol developed by Netscape to provide secure communications on the internet.

Peter Cochrane's Uncommon Sense: Your communications - compromised

But if the system is an omni-directional mobile phone or wireless LAN (WLAN), or just a PC on a desk that simply radiates energy in all directions, it can all be picked up with relatively unsophisticated equipment.

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.
