Demand for transceivers, base-bands, and power amplifiers, as well as other WiFi components, is increasing according to many published reports.

While WiFi transceivers with on-chip complementary metal oxide semiconductor (CMOS) power amplifiers will take more of the market, analysts expect MIMO and 802.11n in higher power systems to drive an increase in the market for external gallium arsenide (GaAs) and silicon germanium (SiGe) power amplifiers and front-end modules.

The manufacturing of WiFi equipment is also of concern to policymakers -- especially in California. Legislation introduced there compels manufacturers to choose one of several ways to protect consumers, and prevent criminals from illicitly linking to another person's WiFi connection.

Wireless market niches are growing much faster than the overall telecommunications industry. And that kind of adoption precludes wireless from being a bubble.
