The Teltonika RUT240 is a compact, cost-effective industrial 4G/LTE Wi-Fi router designed for professional applications. It supports high-performance mission-critical cellular communication and operates effectively in harsh and hazardous environments with a wide operating temperature range. The router features a single-band (2.4 GHz) Wi-Fi 4 (802.11n) capability with a maximum WLAN data transfer rate of 150 Mbit/s. Equipped with an Ethernet LAN interface that supports Fast Ethernet with data rates of 10,100 Mbit/s, the device adheres to networking standards including IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.3, and IEEE 802.3u. It offers various security algorithms such as 3DES, 128-bit AES, 192-bit AES, 256-bit AES, DES, SNMP, SSH, WEP, WPA-PSK, and WPA2-PSK to ensure secure data transmission. The router is compatible with mobile network generations up to 4G and supports 2G standards (EDGE, GPRS, GSM) and 3G standards (DC-HSPA+, UMTS). It includes an external SIM holder, digital input/output, and signal strength status LEDs for efficient network management. External SMA antenna connectors allow for optimal antenna placement to enhance signal reception.
