While global Wi-Fi use is set to explode over the next five years, revenue from the technology is due to shrink, leading to a consolidation of the market, according to a report released this week by Pyramid Research LLC. Worldwide Wi-Fi users will number 707 million by 2008, Pyramid predicted, yet revenue per user will drop from around US$30 a month this year to $3 a month in five years. [MacCentral]
