The Open Base Station Architecture Initiative (OBSAI) aims to create an open market for cellular base stations. An open market will substantially reduce the development effort and costs traditionally associated with creating new base station products. OBSAI had only three members when it was created in 2002. Now it has 130 members. Especially noticeable has been the increase in the number of WiMax companies joining and participating in the integration of WiMax into the currently available OBSAI open interface specifications. More than one-third of the membership now consists of companies actively working with WiMax technology. Web site
