Worldwide, wireless subscriber growth is experiencing robust expansion after several years of slower growth due to the economic downturn of the last few years, reports In-Stat. By 2009, the worldwide wireless market will grow to more than 2.3 billion subscribers. There will be no relief from the ongoing battles for airlink supremacy over the next several years. "GSM's steady growth through 2007 will turn negative as operators move subscribers to third-generation (3G) WCDMA," says David Chamberlain, In-Stat Senior Analyst. "While the second-generation GSM system (including GPRS & EDGE) will remain the dominant airlink throughout the forecast period, CDMA airlink standards (CDMA & WCDMA) will soon encroach on GSM's numbers. By 2009, WCDMA networks will be providing service for over 40 percent of the world's CDMA users." However, those inroads are much less dramatic when classifying WCDMA as an evolution of the GSM system. The total number of new subscribers in 2004-2009 is expected to be 777.7 million worldwide.
What was once a simple, unidirectional flow of electricity from centralized power plants to passive consumers is evolving into a complex, intelligent network where millions of distributed resources actively participate in grid operations. This transformation, powered by smart grid technologies, represents one of the most significant infrastructure shifts of our time. It promises to reshape how we generate, distribute, and consume energy. At its core, the smart grid represents far more than mere digitization of existing infrastructure. This bi-directional capability is fundamental to understanding why smart grids are becoming the backbone of modern energy systems, facilitating everything from real-time demand response to the integration of renewable energy sources. Smart Grid Market Development By 2030, smart grid technologies are projected to cover nearly half of the global electrical grid, up dramatically from just 24 percent in 2025. This expansion is underpinned by explosive gr...
