Also in the following links, it is possible to be guided to know more in detail if the modem is operating in adequate signal conditions:
Mobile Signal Strength Recommendations
In this case, it is required to install the equipment outside closets or furniture, preferably near a window to have higher signal gain,
The antennas should be perpendicular to the floor, or at 45 degrees since this is the polarization used for cellular phone base stations. Maintain line of sight from the device to the provider's base station if possible.
What is the polarisation of a GSM or LTE network?
If the signal strength were not improved, consider testing equipment in an open area, in another city area, or consult the cellular provider if service is feasible where it is intended to use the product, sometimes providers do not offer indoor coverage for their services on the edge of his coverage areas.
