ASTRI has been developing LTE technologies since 2008 and has become one of the global leaders in LTE small cell and terminal baseband cores. Moving forward, ASTRI has initiated the cross domain R&D effort known as “Thrust” to best synergize our resources and strengths of difference research groups. The Thrust on “Open Broadband Wireless Network and Applications” is the first Thrust of ASTRI. It aims to enhance our core competence technologies in baseband, RF and software to provide LTE small cell infrastructure solutions while leveraging cross domain effort to develop technologies for innovative applications.
