其中eMBB应用场景（由于技术积累，更容易实现）主要关注的是移动通信领域，即手机终端市场。而在移动通信传输过程中，影响传输质量的最主要的芯片就是基带芯片（由于高度集成，也可叫调制解调芯片或基带调制解调芯片） ，其作用是将传统的声音、图像等模拟信号（连续变化的物理信号）编译成可识别或处理的低频的信号，后可通过射频模块（将低频信号变成高频信号），经天线（更适合传输高频信号）发送到基站。</td></tr></table> </div> <div id="comment_1714414" class="cm"> </div> <div id="post_rate_div_1714414"></div>
