Differences between 3G and 4G sim card routers

The industrial-grade 3G sim card router is a device that USES 3G network for wireless data transmission, while the industrial-grade 4G wireless router is a device that uses 4G network for wireless data transmission. The main difference between the two is the wireless communication module. Industrial-grade 4G sim card routers have a default theoretical communication rate of up to 100M for CAT4, with options for CAT6 or even CAT12. 3G networks have transmission rates of only 2-3M. Aiming at the 4G network mainly promoted in the domestic market, E-Lins' 4G/3G industrial grade sim card router is not only suitable for domestic use, but also suitable for international use.

Support VPN client (the PPTP, L2TP, IPSEC and GRE) (note: only the VPN support) supports a variety of top and bottom line trigger mode, including SMS, telephone ringing, serial port data, network data trigger line up and down mode support APN/VPDN support wireless video monitoring and dynamic image transmission support DHCP server and DHCP client, DDNS, firewalls, NAT, DMZ host support functions such as TCP/IP, UDP, TELNET, FTP, HTTP, etc to perfect the network protocol.

Industrial grade 3g/4g router USES the 32-bit high performance industrial communication processor, supporting platform based on embedded real-time operating system software, system integration of the whole series from the logical link layer to application layer communication protocol, support static and dynamic routing, the PPP and the PPP client server, VPN (including the PPTP and IPSEC), a DHCP server and DHCP client, DDNS, firewalls, NAT, DMZ host, and other functions. To provide users with safe, high speed, stable and reliable, a variety of protocol routing forwarding wireless routing network.

For example E-Lins’ H685 router.
