Description

Lantronix 88-CAT4ATTA US LTE CAT 4 Internal Modem with External Antenna

Overview

The Lantronix 88-CAT4ATTA provides cellular connectivity for devices that require a reliable LTE CAT 4 connection specifically for AT&T networks. This internal modem, bundled with an external antenna, is designed for deployments where wired network access is unavailable or impractical, such as remote surveillance sites or mobile command centers. The inclusion of an external antenna ensures improved signal reception in challenging RF environments, crucial for maintaining consistent data transmission for systems relying on the 88-CAT4ATTA.

Compatibility

This modem is engineered for seamless integration with Lantronix LM80 and LM83X series devices. It functions as an internal component, requiring specific chassis support from these compatible product families. Ensure your LM80 or LM83X unit is configured to accept this specific AT&T-focused LTE CAT 4 modem.

Installation Notes

Installation requires opening the host LM80/LM83X enclosure. The modem connects internally, and the included external antenna must be routed to an optimal location for signal acquisition. Proper antenna placement is critical for achieving maximum data throughput and connection stability. Consult the host device's installation manual for specific internal component mounting procedures.
