Product Description
With the development of network technology, smart phones and laptops have become popular. Unlike traditional wired phones, mobile smart phones allow users to easily access the Internet, download or upload files, and use other applications.
Long Term Evolution/Evolved Packet Core (LTE/EPC) is an innovation that relies on GSM/EDGE and UMTS/HSPA technologies, which can increase capacity and speed by using different radio interfaces and improvements in core networks. EPC refers to the core network architecture that aggregates access networks including LTE, 3G or 2G.
