LTE Upgrade

4G LTE networks are keys to supporting the rapid rate and higher volumes of mobile data traffic growth driven by increased smartphones and connected devices. As a result, LTE upgrade deployment has been the top priority in operator action list in order to meet the demands.


Indoor LTE deployment to achieve good MIMO performance requires high SINR and good balance between the paths. Furthermore, indoor passive inter-modulation (PIM) interference issues are exacerbated in multi-carrier and multi-system circumstances, which may result in poor user experience.
