1. Product Introduction
1.1 Overview
SMT-CW230, which belongs to Customer-Premises Equipment (CPE), is the combination of two devices; one is a cable modem that an
existing network carrier lends and provides to users. The other is a sharing device that users formerly had to buy on their own.
Existing modems have some limitations on installation because users must relocate their cables indoors from outside. However, the SMT-
CW230 uses the Wireless of the WAN that connects outside. Therefore, it can be transferred and installed easily without any space
limitations.
