Bandwidth Bottleneck

Bandwidth Bottlenek Chart (IEEE Spectrum) - RF CafeThis chart from the January 2013 edition of IEEE's Spectrum magazine illustrates the devolution of Internet data rate speeds in the U.S. over the last decade and a half. Speeds increased nearly logarithmically (linearly on a log scale) beginning around 1992, then by 2001-2002 started falling below the straight line. We should be at around 10 Tbps rather than the 100 Mbps where we are today - a factor of 100. Demand for data bandwidth has far outpaced the ability to provide it. Don't expect big improvements anytime soon. A lot of money that could go into research and implementation is redirected for providing mandated free phones, computers, and service both here and in 'developing' countries - a hidden tax for people who pay their own bills. The story incorrectly says the trend began with the '2001' tech bubble burst, but the bubble actually burst in the spring of 2000 when NASDAQ and the DOW fell hard six months ahead of the fall election. The September 11, 2001 terrorist attack was the knife in the back for any near term infrastructure improvement as priorities shifted elsewhere. We are expected to forget that.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
