Making Network Connection Easy with 4G LTE Cellular Gateway
PLANET ICG-2420G-LTE is a reliable, secure and high-bandwidth communications industrial- grade cellular gateway for demanding mobile applications, M2M (machine-to-machine) and IoT deployments. It features 4G LTE (Long Term Evolution), four Ethernet ports (3 LAN and 1 WAN), serial ports, DI and DO interfaces and VPN technology bundled in a compact yet rugged aluminum case. It establishes a fast cellular connection between Ethernet and serial port equipped devices.
High-performance 4G LTE
The ICG-2420G-LTE supports LTE 2x1 DL MIMO technology which can reach a download (DL) speed of up to 150Mbps and an upload (UL) speed of 50Mbps. The Cellular Gateway also supports multi-band connectivity including LTE FDD/TDD, WCDMA and GSM for a wide range of applications.

Dual SIM Design
To enhance reliability, the ICG-2420G-LTE is equipped with dual SIM slots that support failover and roaming over to ensure uninterrupted connectivity for mission-critical cellular communications. It provides a more flexible and easier way for users to create an instant network sharing service via 4G LTE whenever in public places like transportation, outdoor event, etc.
GPS Included
The ICG-2420G-LTE is equipped with one convenient feature and that is GPS (Global Positioning System). It is a positioning system based on a network of satellites that continuously transmit necessary data. More signals transmitted from more satellites can triangulate its location on the ground, meaning any location can be easily tracked anytime.
Cost-effective VPN Solution
The ICG-2420G-LTE provides a complete data security and privacy feature for access and exchange of sensitive data. The full VPN capability of the ICG-2420G-LTE including built-in OpenVPN and IPSec VPN functions with DES/3DES/AES encryption and MD5/SHA-1 authentication makes the shared connection more secure and flexible. The IPSec VPN also makes the private tunnel over Internet more secure for enterprises doing business transactions.
Remote Manageable Solution for Ethernet to RS232/RS485 Applications
PLANET ICG-2420G-LTE’s serial RS232/RS485 interface can be converted over the Fast Ethernet networking. It can operate as a virtual server or client where IP-based serial equipment can be managed. The ICG-2420G-LTE helps save the network administrator’s valuable time in detecting and locating network problems, rather than visual inspection of cabling and equipment.
Superior Management Functions
For networking management features, the ICG-2420G-LTE provides such functions as DHCP server, DMZ and Port Forwarding, as well as full secure functions including Network Address Translation (NAT), IP/URL/MAC filtering. The ICG-2420G-LTE has 4G and WAN connection failover characteristics, which can automatically switch over to the redundant, stable WAN connection to keep users always online without missing any fascinating moments.

User-friendly and Secure Management
For efficient management, the ICG-2420G-LTE is equipped with console, web and SNMP management interfaces. With the built-in web-based management interface, the ICG-2420G-LTE offers an easy-to-use, platform independent management and configuration facility. The ICG-2420G-LTE supports SNMP and it can be managed via any management software based on the standard SNMP v1 or v2 Protocol. Moreover, the ICG-2420G-LTE offers the remotely secure management by supporting SSHv2 and SNMP v3 connection where the packet content can be encrypted at each session.
IPv6/IPv4 Dual Stack Capability
The ICG-2420G-LTE supports both IPv4 and IPv6 Protocols. As more network devices are growing and the needs for larger addressing and higher security become critical, the ICG-2420G-LTE is the best solution for applications of 4G LTE and serial communication to connect with the IPv6 network.

4G LTE Cellular Communication Solution
PLANET ICG-2420G-LTE adopts 4G LTE cellular technology and thus breaks the 100m limitation of RJ45 transmission. Moreover, wherever there is a cell site, the data rate can be transmitted as far as the distance goes. To avoid data loss affected by an unexpected breakdown connection on the part of ISP, the ICG-2420G-LTE has dual SIM card slots, meaning it can support two different ISPs for redundancy.
