  • 4G LTE Modules for Transparent Transmission - USR-LTE-7S4


    4G Module USR-LTE-7S4 is used to transmit data between a serial port and network server by Operator network. It is configured by AT Command and work in dual transparent transmission mode.
    USR-LTE-7S4 is in small size, which is widely used in LTE, WCDMA, TD-SCDMA. It works in transparent transmission mode and more functional software. It has high speed and less time-delay supports FTP protocol.
    USR-LTE-7S4 is also compatible with 2G module 7S2/7S3, the user can replace 7S3 easily. We add Watchdog function in firmware to ensure the stability if work for a long time.
