UMML – 4G LTE Modem with Worldwide Coverage

4UMML 4G LTE modem provides Wireless Data Communications to enable Remote Control of Smart Grid devices.

The 4UMML cellular modem is a compact device optimized for data transmission and using different services offered by the mobile operators.

Rapid implementation

The 4UMML modem offers rapid implementation of current telecontrol and AMR applications in order to take full advantage of 4G technologies:

  • SMS: short messages reception and sending.
  • CSD: data calls by circuit switching establishment.
  • HSCSD: establishing communications for data transfer through high speed circuit switching (2+1).
  • GPRS: Class 33. Although simultaneous registration to GPRS and GSM is possible, in a given moment only one connection is
  • 3G: supports 3GPP R8 WCDMA.
  • LTE Cat 1. Worldwide coverage.


  • LTE FDD Bands: B1/B3/B7/B8/B20/B28A.
  • LTE FDD Data: Max 10Mbps (DL)/Max 5Mbps (UL).
  • WCDMA Bands: B1/B8.
  • WCDMA Data: Max 384Kbps (DL)/Max 384Kbps (UL).
  • GSM Bands: B3/B8.
  • EDGE: Max 296Kbps (DL)/Max 36.8Kbps (UL).
  • GPRS: Max 107Kbps (DL)/Max 85.6Kbps (UL).
