Product information

Description

The LT400 shares a 4G LTE connection wherever you need it. It supports 4G LTE FDD and TDD bands and 3G networks, offers Wi‑Fi on the 2.4 GHz band with up to 300 Mbps, and provides flexible operation modes for home, office or temporary setups. The router includes high‑gain antennas for improved signal sensitivity and supports DDNS and VPN for remote access and secure tunneling.

Advantages

Support for both FDD and TDD LTE ensures compatibility with many ISPs and mobile operators worldwide. Built‑in VPN enables a secure private tunnel for remote offices and teleworkers. Compatibility with more than 15 DDNS providers simplifies remote management when the public IP address changes. High‑gain antennas increase reception range and indoor penetration, and multiple operation modes allow the LT400 to act as a primary router, a WAN‑backed gateway or a simple 4G backup.

Key specifications

  • 4G LTE FDD: B1 / B3 / B7 / B8 / B20 (2100 / 1800 / 2600 / 900 / 800 MHz)
  • 4G LTE TDD: B38 / B40 (2600 / 2300 MHz)
  • 3G: DC‑HSPA+ / HSPA+ / HSPA / UMTS B1 / B8 (2100 / 900 MHz)
  • LTE download speed: up to 150 Mbps; upload: up to 50 Mbps
  • Wi‑Fi: 2.4 GHz, up to 300 Mbps
  • VPN support for secure tunneling
  • Compatibility with 15+ DDNS providers
  • High‑gain external antennas
  • Operation modes: LAN (4G router), WAN + 4G (primary WAN with 4G backup)

How to use

Insert an active SIM card into the LT400 and power on the device. Access the web administration page to configure the mobile network settings or select automatic detection. Set up Wi‑Fi SSID and password on the 2.4 GHz band and configure VPN or DDNS if remote access or secure connections are required. For office deployment, choose WAN + 4G mode to provide Internet primarily via wired ports while keeping 4G as backup; for simple home or vacation use, operate in LAN mode to share the mobile data connection over Wi‑Fi and Ethernet.

Recommendations

Place the LT400 near a window or higher position for better cellular reception, and ensure the SIM plan supports the required data speeds. Use the VPN and DDNS features when remote secure access to the local network or router administration is necessary.

Modulation: Modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal (High Frequency Signal), with a modulating signal which typically contains information to be transmitted. The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a bandpass filter limits the frequency range to between 300 and 3400 Hz), or over a limited radio frequency band. The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio frequency band or a cable TV network channel.

Product comparison

The desktop router Cudy LT400 is compared with several similar network devices, including the Cudy LT400E, Cudy LT500, Asus 4G-AX56, MERCUSYS 300 Mbps Wireless N 4G LTE, and Cudy WR1300. All these devices are designed to provide internet connectivity in homes or small offices, but they differ in Wi-Fi standard support, SIM card slot availability, and wired network speeds. The primary differences lie in the wireless generation, support for 2.4 GHz and 5 GHz bands, and the presence of a built-in LTE modem for mobile internet usage.

⚙️ In the specifications comparison table below, we will compare key characteristics such as the Wi-Fi standard, maximum wireless data transfer rate, type and number of Ethernet ports, antenna design, as well as the presence of a SIM card slot and 3G/4G modem support.
