In a LTE deployment what is the purpose of the CPE? The UE attach to the eNB that will communicate with the cloud EPC. So whats exactly the function of the CPE and why it must support the eNB frequency band? Isn’t the CPE a normal router that provide internet connection between the eNB and the EPC?
How does the CPE connect to the eNB? It connects in the eNB LAN port or communicates with the eNB through radio frequency?
Thanks in advance,
