Product Features
Technical Overview
This modem/router operates on cellular and Ethernet broadband transmission technologies. The cellular radio supports LTE Advanced as the primary high-speed data standard, with fallback to HSPA+, DC-HSPA+, and UMTS networks for broader compatibility. It is equipped with two external antennas to optimize signal reception across the supported LTE bands, which include common frequencies like 700 MHz, 850 MHz, 1800 MHz, and 2100 MHz.
On the wired side, the device features Gigabit Ethernet technology across its ports. The connectivity suite includes four standard network RJ-45 ports for connecting local devices, one dedicated broadband RJ-45 port for WAN uplink, and a PoE-enabled RJ-45 port that can deliver both data and electrical power over a single cable. A built-in USB port adds flexibility for connecting storage or other peripherals.
Relevant factors for this section include Broadband Transmission Technology, Cellular Network Supported, Cellular Data Connectivity Technology, Number of Network (RJ-45) Ports. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
