Overview

The Zoom 4501 3G WiFi Router is purpose-built to solve a common mobile broadband challenge: taking a single USB 3G modem's internet connection and sharing it wirelessly with multiple devices. Rather than limiting your mobile broadband to one computer with a USB modem plugged in, this router lets you plug that modem into its USB port and broadcast the connection as a WiFi network. Laptops, tablets, phones, and other wireless devices can then connect simultaneously, making it useful for small offices, temporary setups, or locations where traditional broadband is unavailable.

The router supports 802.11n/g/b wireless standards, with 11n providing the best available throughput for connected devices, though actual internet speeds will be governed by your 3G modem's connection. A 10/100 Ethernet port is also included for a single wired device connection. It is worth noting that this is a 3G-era device, so users should ensure their USB modem is compatible and understand that data speeds will reflect 3G network capabilities rather than modern LTE or 5G performance levels.
