4G/LTE, LTE-Advanced Baseband Solutions

4G/LTE, LTE-Advanced Baseband Solutions

  • ASTRI is one of the worldwide pioneers in LTE and beyond standard compliant communications technologies including baseband and upper layer protocol stacks. In collaboration with industry partners, we delivered the world’s first commercial grade FDD/TDD dual mode LTE small cell and TD-LTE terminal baseband core reference designs. Our reference designs are industry proven, having passed interoperability tests with infrastructure vendors and operators. In particular, we enable partners to pass through a leading operator’s stringent tender tests on small cells and terminals.

    LTE/LTE-advanced small cell solutions

    ASTRI is developing the next generation of LTE and LTE-Advanced small cells based on a variety of highly integrated SoC platforms.
