RF specification
Antenna
The antenna must meet the requirements as in the table below:
| Antenna frequency range | Supporting GSM, UMTS or LTE frequencies |
| Impedance | 50 Ω |
| DC impedance | 0 Ω |
| Gain | 0 dBi w/o cable; 2dBi w/ cable |
| VSWR (with cable) | -10 dB |
The antenna chosen for working with the modem should best fit to the circumstances of the environment it is used in. When the modem is placed in a room, or somewhere where the range of networks signal is too low, an outdoor or a specific indoor antenna should be used.
