Brief Introduction 

This specification describes the electrical characteristics, RF performance, size and application environment of WG1602. It can help end users and developers quickly learn this model.


WG1602 is a 4G router with two 4G modules. It can access the Internet through 4G sim cards or 1000Mbps WAN port. Support load-balance and network backup.


Product Feature

  • USB2.0 bus standard
  • TF Card interface standard
  • SIM/USIM interface standard
  • PCI- Express bus standard
  • IEEE802.11n/g/b/a/ac
  • IEEE802.3/802.3u/802.ab
  • Mini PCI Express Card Electro mechanical Specification Revision 1.0-2003
  • 4G mobile communication standard

4G Mobile Communication Function


This product has two built-in PCIe interfaces of USB2.0 bus, which can be used to expand the function of 4G mobile communication. The frequency bands depends on the 4G modules.


As shown in the "Product Picture" , two 4G modules are each corresponds to two SIM cards. In this way, a dual-module & dual-SIM card can achieve traffic superstition or 4G network backup through software control.
