The 4G LTE CPE(Customer Premises Equipment) is a terminal device that converts 4G cellular network signals into wired or wireless LAN signals, supporting multi terminal shared network access. The 4G LTE CPE's core function is to realize high-speed Internet access in a fiber free environment through the built-in 4G network, and the 4G LTE CPE also has routing, switching and network security functions. Simultaneously equipped with voice gateway function, providing an integrated solution of "wireless network+traditional voice services" for scenarios without fixed line telephone coverage. By integrating SLIC (User Line Interface Circuit) modules, 4G cellular network signals are converted into analog telephone signals, which can be directly connected to ordinary telephones (POS phones), fax machines, and other devices to achieve dual functions of voice calls and data access. The core competitiveness lies in the ability to integrate multiple services, which can provide high-speed cellular network access and meet traditional voice communication needs. The 4G LTE CPE is suitable for scenarios such as enterprise office, industrial Internet of Things, and emergency communication. The 4G LTE CPE's "multi-functional" design significantly reduces deployment costs and is a benchmark solution for the integration of wireless communication and traditional fixed line telephones.
