Lightning-fast internet connectivity

The Zyxel LTE5388-S905 employs 3GPP UE downlink Category 16, with high-level practice LTE-A technology and data rates of up to 580/30 Mbps (DL/UL). The built-in 4x4 MIMO high-performance antennas increase your service capacity and expand the internet coverage for your subscribers.

Easy installation with a space-saving design

The simple and intuitive device design of the Zyxel LTE5388-S905 provides your subscribers with trouble-free installation and configuration experience, while allowing you to maintain an excellent service quality with a lower OPEX.

Boosts efficiency of the existing infrastructure with dual-mode flexibility

The Zyxel LTE5388-S905 supports the bridge/router function, allowing you to start a new deployment or upgrade services by connecting to the subscriber’s existing broadband router with a lower CAPEX.

Remote management for lower OPEX

With TR-069, TR-181 and TR-143 support, the Zyxel LTE5388-S905 effectively secures OPEX by reducing the frequency of on-site support and by providing simplified diagnostic, configuration and troubleshooting processes.

Network setup and management in hand

Zyxel LTE5388-S905 supports Zyxel Air, an in-house developed app for Zyxel Fixed Wireless Access devices. The simple, intuitive yet powerful app simplifies the setup, configuration, and management of your customers' home or office networks. Your technicians can provide prompt and satisfying services with reduced average service time for each customer.
