Single Frequency Network Concepts for Cellular OFDM Radio Systems

Overview For broadcasting systems like DAB (Digital Audio Broadcasting) or DVB-T (Digital Video Broadcasting - Terrestrial) the concept of SFNs (Single Frequency Networks) is well known. It allows the constructive superposition of identical signals from more than one transmitter based on OFDM (Orthogonal Frequency Division Multiplex). In this paper the SFN concept is investigated for bi-directional wireless communication systems like the novel ETSI standard H/2 (HIPERLAN/2), a broadband WLAN (Wireless Local Area Network) radio system.

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.

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. Texas Instruments' 'turbo Wi-Fi' technology may be downshifting out of the wireless networking fast lane...

Radioactive: Bluetooth - survival of the fastest

The other approach sends out the signal in a single stream which reduces the complexity of the transmitter and the power it requires. The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS...

Qualcomm buys Flarion for $600m

Qualcomm was attracted to Flarion by its team and portfolio of intellectual property, which includes the next-generation wireless technologies OFDMA (Orthogonal Frequency Division Multiplex Access) and FLASH-OFDM, known as a type of 3.5G.

Peter Cochrane's Blog: The search for spectrum

But we have a new raft of digital systems being rolled out that have intelligence built into the transmitter and receiver. We have hundreds of radio and TV broadcast transmitter masts surpassed by the thousands installed for mobile networks, which...

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...

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.
