Dear Expert :

As i know the LTE throughput depends on the following parameters:Bandwidth,Channel quality,Network load.

The Bandwidth for Cat-1 & Cat-4 are same and let's asume that the Network load for Cat-1 & Cat-4 are also same , so the peak downlink rate differece for Cat-1 & Cat-4 should related with Channel quality, right?

If yes , please help point out the difference for Channel quality between Cat-1 & Cat-4.

Best Regards
