• Europe and Asia are also potential markets, but Beyer says that even though the 2.4-GHz band is also public in those markets, the limits on radiated power are much stricter there, at 100 mW of effective radiated power compared with 4 W in North America. This makes a huge difference in range and coverage. European and Asian authorities have been petitioned to increase these power limits
• The February 2002 FCC report cited a survey from the Strategis Group that only 12 percent of on-line customers were willing to pay $40 per month for high-speed access, a number that rose to only 30 percent when the price was dropped to $25 per month.
