Public broadband access via wireless is not only a benefit to business travelers but is also an interesting business opportunities in itself. Broadband wireless internet access via hot spots in hotels, airports, convention centers, coffee shops, restaurants, etc. is a fast growing trend. Hot spots provide internet access for hire. Relatively economical to set up, all that is required to create a simple hot spot is a broadband connection and a wireless router. May hot spots use T1 for its high bandwidth, but DSL, cable and fixed wireless can also be used.
WiMAX technology can make high speed wireless broadband internet services available to much larger areas than can typical Wi-Fi hot spots. WiMAX implementations can provide a wireless range of up to 30 miles or 50 kilometers, much greater than the physical distance limitations of Wi-Fi hot spots or DSL, WiMAX technology can also be used to interconnect existing Wi-Fi networks.
WiMAX Technology promises many strategic opportunities, not just as a backhaul solution for Wi-Fi delivering additional bandwidth to hot spots, but potentially for 3G networks too. WiMAX Technology initially may be deployed as a wireless backhaul solution, but will be upgraded to a mobility application, once the 802.16e standard is approved and WiMAX Technology capable client devices enter the market, marking a major increase in the anticipated market.

WiMAX Technology can compliment existing and emerging 3G mobile and wired networks, and can play a significant role in helping service providers deliver converged services that can be accessed using a broad range of devices on a wide variety of networks.
At the technical level, 3G and WiMAX Technology solutions fit well together by providing different capabilities while allowing for seamless integration. 3G technologies have evolved over many years to become highly spectrally efficient, allowing operators to take advantage of costly spectrum dedicated to mobile services. 3G CDMA technologies such as W-CDMA and CDMA 2000 1xEV-DO provide high through puts in low bandwidths as 5 MHz and 1.25 MHz, respectively.
