Co-Existence of 802.11g WLANs With Bluetooth

Overview Orthogonal-frequency-division multiplexing (OFDM) based wireless local-area-networks(WLANs) will be implemented in the 2.4 GHz Industrial-Scientific -Medical (ISM) band. The advantages of OFDM WLANs are very high data rates, resilience to multipath and extended operating range. However, they will encounter interference from Bluetooth (BT) devices. In this paper, the co-existence issue of OFDM WLANs with BT devices is examined and the use of symbol erasures to ameliorate this interference source is proposed. Simulation results show that the combination of data rate reduction and symbol erasures helps to prevent irreducible packet error rate (PER) when the signal-to-interference ratio (SIR) is low.

The Bloor Perspective: Transmeta versus Intel, HavenCo, and Chinese walls come tumbling down

While we do not expect it to succeed, we believe that if governments fail to challenge it quickly then it could become a symbol of a political movement based entirely in cyberspace. HavenCo appears to comprise a group of mainly US libertarians that...

TI's 'turbo Wi-Fi' - still born?

In the 802.11g standards battle, PBCC eventually lost ground to OFDM, or Orthogonal Frequency Division Multiplexing, as the modem of choice. The technique TI uses to boost turbo Wi-Fi's speed is known as PBCC (Packet Binary Convolutional Coding).

Bluetooth shatters milestone

Another important improvement is the addition of adaptive frequency hopping (AFH), which is designed to reduce interference with other devices that use the same 2.4GHz wireless spectrum -- including some cordless phones and increasingly-popular Wi...

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. This increases the signal's range by reducing interference. Essentially this means that all future high-speed Bluetooth devices...

Wi-fi patent threat looms after US ruling

Csiro claims its patent covers a core method for transmitting wireless signals that use orthogonal frequency division multiplexing (OFDM) modulation, which breaks signals into different parts to transmit data simultaneously over different...

Complexity makes travellers miss their connection

In the not too distant future, you will be able to add 3G Long Term Evolution (LTE), mobile WiMax, multiple in multiple out (MiMo) and orthogonal frequency division multiplexing (OFDM) to the mix. B is for Bluetooth

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.
