Broadband access is quickly becoming ubiquitous. Among the technologies for access, wireless is becoming the preferred technology for reasons of mobility, cost, and convenience. In this talk we begin with the recent trends in the wireless access market, summarize the key technical developments that are leading to increasing reach and speeds. WiMAX is almost here but the competing technologies, such as HSPA, EV-DO, LTE, IEEE 802.20, IEEE 802.22 are also trying to catch up fast and the next generation WiMAX is already being designed. These and other developments will be presented.
