Wireless router Cudy IR04_EU 300 Mbps, 2.4 GHz Wi‑Fi 4 (802.11n), 4x Fast Ethernet, 1x USB 2.0, LTE (4G) support

Cudy IR04_EU is a compact wireless router with built-in 4G support, delivering up to 300 Mbps on the 2.4 GHz band using Wi‑Fi 4 (802.11n). It is equipped with a 580 MHz single-core processor, 128 MB of internal memory and 16 MB of flash storage, two internal antennas in a 2x2 MIMO configuration, four Fast Ethernet LAN ports and one USB 2.0 port. The aluminium-alloy housing includes LED power indication and a reset button. The router accepts 100–240 V AC input and provides a 12 V DC output at 1 A, and operates in a wide temperature and humidity range.

Advantages

The router supports both LTE-TDD and LTE-FDD networks and is compatible with WCDMA 3G standards, enabling mobile broadband connectivity where wired internet is unavailable. Internal 2x2 MIMO antennas and Wi‑Fi 4 deliver stable wireless coverage on the 2.4 GHz band. Multiple wired interfaces, including four Fast Ethernet LAN ports and a USB 2.0 port, provide flexible connectivity options for home or small office setups. Compact aluminium-alloy construction and wide operating temperature and humidity tolerances make the device suitable for varied installation environments.

Suitable for

• Home internet access using ADSL/cable fallback to 4G mobile network
• Small office or remote site requiring mobile broadband backup
• Connecting wired devices via multiple Fast Ethernet LAN ports
