1. Dual Band Wi-Fi Router/Repeater/Extender Gateway Introduction

1.1. Purpose and Description

The DSGW-021 LTE Cat4 Router Gateway is designed for IoT Gateway developers and complies with the latest IEEE 802.11ac Wi-Fi standard. It delivers consistent high-speed data transmission for multiple devices simultaneously.

With its dual-band design, it facilitates versatile and stable wireless connections over long distances. Ideally suited for medium-sized homes, This router gateway also supports BLE5.2, and Zigbee, enabling it to connect with end devices that support different protocols. Potential usage scenarios include home use, smart home integration, small business offices, remote work settings, Internet of Things (IoT) applications, and educational environments.

Further, with pre-integrated, comprehensive, and fully documented out-of-the-box guidance and support, developers can create a custom firmware, starting from the lowest layer of the hardware

1.2 Product Feature Summary

  • 4G CAT4 Network: shares internet access with up to 64 Wi-Fi devices and enjoys download speeds of up to 150 Mbps.
  • AC1200 Wi-Fi: creates simultaneous dual-band Wi-Fi networks, with maximum speeds of up to 300 Mbps on the 2.4 GHz band and 867 Mbps on the 5 GHz band.
  • Plug a SIM Card and Play: No configurations are needed; compatibility with SIM cards in over 100 countries is assured by years of field testing.
