The market for embedded Wi-Fi clients (including mobile PCs, PDAs and phones) will grow at a 66.2% Compound Annual Growth Rate (CAGR) to 226.0 mln units shipped in 2008. After five years of healthy growth since its mainstream commercialization, the worldwide Wi-Fi hardware market (i.e. network infrastructure and adapters) finally surpassed $1.0 bln in (4Q 2003) quarterly revenues. There has been a significant growth in Wi-Fi-enabled notebook PCs, as 55.0% of the 32.1 mln notebook PCs shipped in 2003 contained embedded Wi-Fi adapters.
The Wi-Fi Mini PCI card represented 49.1% of the Wi-Fi adapters shipped, and enabled most of the Wi-Fi mobile PCs (e.g. notebook and tablet PCs) in 2003. Conversely, PC Cards held a quickly eroding 38.8% market share in 2003 after dominating the market with a 58.3% market share in 2002. In-Stat/MDR expects that the Wi-Fi Mini PCI card will continue to capture an increasing percentage of the total Wi-Fi adapter market over the next five years.
