Integrated cellular modem

See also: LTE Modem menu.

The integrated cellular modem (also known as an LTE modem) can be used to send or receive RTK corrections. This enables you to connect to VRS networks in your area or set up your own IBSS service. For more information on VRS networks, contact your local Trimble representative.

Using the integrated cellular modem requires a SIM card from your local cellular service provider. The SIM card is inserted into the SIM card slot in the battery compartment of the receiver. For more information about setting up your SIM card and cellular service in the receiver, see Step 1. Install the nano-SIM card (optional) or refer to the MPS566 Quick Start Guide.

The MPS566 internal LTE modem supports global cellular service providers using the following bands:

  • Twelve Bands FDD-LTE: 700, 800, 850, 900, 1700/2100 (AWS), 1800, 1900, 2100, 2600 MHz (bands 1, 2, 3, 4, 5, 7, 8, 12, 18, 19, 20, 28)

  • Seven Bands UMTS (WCDMA/FDD): 800, 850, 900, 1700/2100 (AWS), 1800, 1900, and 2100 MHz (bands 1, 2, 4, 5, 8, 9, 19)

  • Quad Band GSM: 850, 900, 1800, and 1900 MHz

Verizon (U.S.) is currently not supported.

SIM card settings

To determine the APN, user name, and password for the SIM card for a:

  • user-provided SIM, contact the cellular service provider.

  • For a Trimble SIM (Trimble Works Subscription), the APN is configured before shipping and the CPIN is managed by the MPS566 firmware. On the web interface, select LTE Modem / Configuration. Click Trimble SIM and then click Validate CPIN. The firmware will set the CPIN.

Finding the IMEI number for the internal LTE modem

  • The IMEI number is printed on the packaging label of the MPS566 box.

  • Using the web interface, select LTE Modem / Summary.

  • On the front screen of the receiver. Fom the Home screen, press Up.

Access the receiver remotely when it only has internet connection over LTE

Outgoing connections over LTE such as a correction stream to IBSS or an email notification don’t require any special configuration, however the incoming connection required for remote management needs one of the following:

  • A publicly routable static IP address. This is a special order from your cell provider, when available.

  • Use a Dynamic DNS system:

    1. A valid Dynamic DNS account. The receiver supports dyn, no-ip, zoneedit, and freedns. These services will provide a host service with a unique URL for the receiver.

    2. A publicly routable IP address from your cell provider. Not all cell providers provide routable IP addresses by default, or at all.

For high-security applications, Trimble recommends using a firewall in front of the receiver. The receiver supports HTTPS connections; these are recommended. See HTTP Server Config.
