Wi-Fi Buys

摘要

Wireless service providers are finally launching high-speed third-generation (3G) networks after years of delay. 3G lets you use your laptop or cell phone to download and swap big files like games, photographs and even short videoclips. Good news for e-shutterbugs and game geeks, but is it bad news for Wi-Fi? No telecom topic is more hotly debated. Yet Wi-Fi isn't in danger. As demand for 3G picks up, so will demand for Wi-Fi. Reason: In very dense areas 3G networks slow to a crawl. The cell sites they use are expensive to install, at least $50,000 to $60,000 each.
