New 4th-generation wireless networking equipment is entering the market. We started with consumer-based wireless equipment with virtually no security, then enterprise quality products with improved security were released. The current standard, the 3rd-generation wireless networks, have centralized controllers that help enable the hand-off between access points as users move about, and even more improved security. The next generation though, based on 802.11n technology, allows all access points to share a channel and greatly improves the hand-off from access point to acccess point. Unlike previous wireless implementations, which require careful placement of access points to maximize coverage while avoiding channel interference, 4th-generation wireless networks allow for denser, and simpler deployments.
