200 is only a theoretical maximum
Talkback I use Netgear 200Mb devices at home and get a reliable 100Mb out of them which is enough for streaming video from a server downstairs to receivers in the bedrooms upstairs. You have to be careful about plugging in things that generate noise on the...

A Control Theoretical Approach to a Window-Based Flow Control Mechanism With Explicit Congestion Notification
White Papers A window-based flow control mechanism is a sort of feedback-based congestion control mechanisms, and has been widely used in current TCP/IP networks. Recently proposed TCP Vegas is another version of the TCP mechanism and has potential to achieve...

An Integrated, Distributed Traffic Control Strategy for the Future Internet
White Papers Due to the lack of a general theoretical foundation, nowadays distributed traffic control mechanisms developed at the networking layer, transport layer, and overlay are largely disintegrated. First, it proposes a theoretical foundation for...

Vodafone mobile broadband to hit top HSDPA speed
News Vodafone has begun upgrading its mobile broadband network to a theoretical maximum download speed of 14.4Mbps, the operator announced on Thursday. Rival British operators offer much lower theoretical maximum speeds.

Super-3G breaks records - and the bank
Talkback Manx Telecom's prices range from 60p to £3 per megabyte — so at the maximum theoretical data rate and the top tariff, you could be paying £5.40 a second, £320 a minute, £14m a month. So the comparison between theoretical and actual throughput is a...

Blu-ray appears to have the DVD lead
Talkback GB more than the theoretical limits of Blue-ray! Oh and the theoretical limit of the holo storage is 1.6TB, ha! Just look at the iPod compared to SONY's efforts today, the MD is dead and all of SONY's flash players pale in comparison.

Report sees countryside broadband speeds lagging
News Fat-pipe speeds rarely live up to the theoretical maximums advertised by ISPs, so the fastest UK region in the thinkbroadband survey — London — achieved an average download rate of 4.5Mbps. LLU has been key to achieving faster broadband speeds in...

M-QAM OFDM and PCC-OFDM Performance in the Presence of Phase Noise
White Papers Theoretical and simulations results for bit error rate (BER) are presented for M-QAM OFDM and PCC-OFDM systems over Rayleigh fading channels. The theoretical results agree closely with the computer simulations.

Vodafone extends its high-speed mobile broadband
News Vodafone's fast mobile broadband uses HSDPA (high speed downlink packet access) technology — sometimes referred to as 3.5G — to offer a theoretical maximum download speed of 7.2Mbps. The upgraded network will also use HSUPA (high-speed uplink...

DSL Max may save BT's broadband blushes
News According to Richard Mahony, an analyst with Ovum, this could mean a theoretical upstream speed of 832kbps, compared to the maximum speed of 256kbps offered by ADSL today. These factors could also mean that some subscribers are not able to get the...

60 GHz networking, the story so far
