Disadvantages of traditional shields

设计简单，质量较差，使用寿命短

Simple design, poor quality, short service life

发射全频段信号，很难准确控制干扰频段，容易干扰基站，影响区外正常通讯 It is difficult to accurately control the interference bandwidth when transmitting the full-band signal, which iseasy to interfere with the base station and affect the normal communication outside the area● 时分系统，百分百干扰基站；TD-SCDMA频段全时隙发射，上行干扰、基站堵塞无法避免，严重影响区外正常通讯Time division system, 100% interference base station; TD-SCDMA all time slot transmission, resulted uplink interference and base station blockage can not be avoided, seriously affect the normal communication outsidethe area● 发射频谱杂散多，影响移动通讯上线，无法满足无线频谱发射规范There are many stray frequencies in the transmitting spectrum, which affects the on-line of mobilecommunication and unable to meet radio spectrum emission specifications
