Gigabit Speed, Wherever You Need It
No more slow internet in locations without fiber optic or VDSL connections. The Cudy LT18 uses the power of the 4G-Advanced Pro standard (CAT.18) and bundles multiple frequency bands into a single, ultra-fast data highway with 5-fold Carrier Aggregation. In combination with 4x4 MIMO technology, theoretical download rates of up to 1.2 Gbit/s are possible. This means for you: 4K streaming, fast downloads of large files, and online gaming without compromise – all via the mobile Network.
Maximum Reliability with Dual-SIM & WAN Failover
For anyone who relies on a stable connection, the Cudy LT18 is the perfect 4G / 5G Routers. It offers you a triple safety net. The two Nano-SIM slots allow the use of cards from two different Network providers. If the primary Network fails, the router switches instantly to the second SIM. Additionally, you can connect a wired internet source (e.g., DSL or fiber optic) via the configurable WAN port. This dual SIM router for failover ensures that you always stay online.
Professional Tools for Full Control Over Your Network
The Cudy LT18 is more than just a simple WiFi Routers – it's a command center for power users. With the Band-Lock function, you force the router to connect to specific, less congested frequency bands to maximize performance and stability. Adjust TTL values to bypass potential restrictions from your provider, and secure your data transmission with encrypted DNS over TLS. The extensive VPN client and server support (incl. WireGuard, OpenVPN, IPsec) allows you to establish secure connections to your company or home network from anywhere in the world.
Future-Proof Connectivity with Wi-Fi 6
What good is the fastest internet connection if the Wi-Fi slows it down? The Cudy LT18 relies on the modern Wi-Fi 6 (802.11ax) standard. This not only ensures higher data rates of up to 1.8 Gbit/s (AX1800) but also works significantly more efficiently thanks to technologies like OFDMA and MU-MIMO. The result: A stable and fast connection for a variety of devices simultaneously, from smartphones and laptops to smart home gadgets – ideal for the modern, connected household or office.

Frequently Asked Questions (FAQ)
Can the Cudy LT18 use two SIM cards simultaneously?
No, the router cannot use both SIM cards simultaneously for bundled speed. It uses the dual-SIM function for redundancy (failover). You can set a primary SIM card, and the router will automatically switch to the second card if the first loses signal or reaches a defined data limit.
Is the Cudy LT18 suitable for use in RVs or remote locations?
Yes, absolutely. Thanks to its high 4G category, the dual-SIM function for switching between different network providers, and the detachable cellular antennas, it is ideal for mobile applications or locations with weak cellular signals. The 12V DC Power Supply also facilitates integration into vehicles.
What does "Band-Lock" mean and what is it useful for?
"Band-Lock" allows the user to instruct the router to connect only to specific cellular frequency bands. This is extremely useful for avoiding overloaded frequency bands and achieving a more stable, often faster connection by selecting a less used band from a more distant cellular cell.
Does the Cudy LT18 support Mesh WiFi?
Yes, the Cudy LT18 is compatible with Cudy Mesh technology. It can function as a main Mesh router and build a seamless WiFi network with other Cudy Mesh-enabled devices for complete coverage throughout the house.
Do I need a special cellular plan for the high speeds?
Yes. To utilize the maximum speeds of 4G CAT.18, you need a cellular plan that supports these high data rates. Additionally, the cellular tower near you must also provide the corresponding technologies such as Carrier Aggregation. The actual speed always depends on your plan and local network coverage.
Which encryption standards does the router support?
The Cudy LT18 supports the modern and secure WiFi encryption standards WPA2 and WPA3, which ensures high security for your wireless network.
