Broadband Network Access using VSAT and WiFi Systems are one way to attend the demand for information in every time and place; where this demand, has been turning into a big change in Telecomunications´ field. The access to information starts to be required in the farthest places, where the terrestrian infra-estructure shows itself almost totally missed. It´s included the VSAT networks (Very Small Apperture Terminal) that offer access for information through a capable satellite network that gives coverage to huge geographic areas. By the same way, the information has got to be gathered at any time and this way, WiFi networks shows itself as the way the user can obtain information, even if while waiting his flight at the airport, or while enjoying a dinner in a restaurant, or in the case of corporations making faster the data sending among their professionals through mobility. The goals of this dissertation are the study of systems characteristics and propagation of the radio waves for the VSAT (Ku band) and Wi-Fi (Wireless Fidelity) networks (2,4GHz and 5,2GHz) in outdoors and indoors areas; the development of a methodology to planning projects for VSAT-WiFi networks and its application in a study case that permits a conclusion of a correct project planning must be done to efficient and good results can be reached.
