What is the difference between digital mobile signal repeater and ICS mobile signal repeater ?

Both digital mobile signal repeaters and ICS (Interference cancellation system ) mobile signal repeaters are used to improve weak cellular reception in areas with poor signal strength .however ,there is a key difference in their technology :

Digital mobile signal repeater : this is a more general term for any repeater that uses digital signal processing (DSP) to amplify and retransmit cellular signals . it offers better signal clarity compared to analog repeaters ,but may still be susceptible to interference issues . 

ICS mobile signal repeater : this is a specific type of digital mobile signal repeater that incorporates interference cancellation technology .using DSP, it can automatically detect and cancel out interference signals caused by factors like feedback between antennas .this leads to improved performance and fewer call quality issues compared to basic digital repeaters . 

Here is table summarizing the key differences : 

In essence ,an ICS repeater is an advanced type of digital repeater that offers better performance due to its ability to cancel out interference .
