OFDM Based WLAN Systems

Overview Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multi-carrier transmission where all the subcarriers are orthogonal to each other. OFDM promises a higher user data rate and great resilience to severe signal fading effects of the wireless channel at a reasonable level of implementation complexity. IEEE 802.11a and HiperLAN/2 have the capability to operate in a range of a few tens of meters in typical office space environment. This paper attempts to connect the different strings of OFDM and create a comprehensive reference. The paper attempts to provide an understanding of OFDM system along with a description of the challenges and research areas for enhancing system capacity and improving link quality.

The Bloor Perspective: Itanium 2, managing LANs and the Info Pro

Is managing desktops actually about enhancing performance and availability or just about controlling the facilities that are available to the users? This will all form a part of the Microsoft System Center, which will act as a unified interface for...

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands.

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. David Perry, product marketing, carrier, VoIP and...

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.
