Smartphones and laptop computers have brought about an explosion in data traffic,and using Wi-Fi to offload data flow has become a trend.This paper suggests that a smart antenna can enhance signal coverage,improved AP/AC can reduce handoff time,PMIP can provide IP mobility,and a relatively transparent Wi-Fi network can be used to provide new services.It proposes seamless coverage and handoff that satisfies medium-speed mobile Wi-Fi and greatly offloads Internet and data traffic.The 2G/3G/LTE network continues to carry voice and other high value-added business.
