| 2127 | | * The following antenna was used for all certifications. Other antennas can be used if they meet the same requirements: Atel-Cab T-AT305, antenna gain all bands 2.14dBi. See info here: [https://www.atel-antennas.eu/wp-content/uploads/2017/01/T-AT305.pdf Link] |

| 2129 | | This is a cellular modem module that is sold pre-certified. |
| 2130 | | |
| 2131 | | Different models come in different speeds, such Cat 1 up to Cat 4 |
| 2132 | | |
| 2133 | | Drivers: |
| 2134 | | * option (at commands), cdc_ether (wwan) |
| 2135 | | |
| 2136 | | The modem can be configured to be in different modes. Mode 0 states in a manual that it cannot be used for data traffic. |
| 2137 | | |
| 2138 | | Mode 3 works with data traffic and can be changed with AT commands to /dev/ttyUSB1: |
| 2139 | | {{{ |
| 2140 | | AT#USBCFG=3 |
| 2141 | | AT#REBOOT |
| 2142 | | }}} |
| 2143 | | |
| 2144 | | Another modem configuration that may need to be looked at is called FWAUTOSIM, which is automatic carrier switching by SIM. For this example, FWAUTOSIM was 0, meaning no automatic switching. |
| 2145 | | |

| 2150 | | |
| 2151 | | Verify the modem is detected with the lsusb command. Then use modem manager to bring the modem up with the following example: |
| 2152 | | {{{ |
| 2153 | | mmcli -m 0 # Look for a large output of information about the modem |
| 2154 | | mmcli -m 0 --enable |
| 2155 | | mmcli --modem 0 --simple-connect="apn=hologram" #replace hologram with actual APN for SIM used |
| 2156 | | dhclient wwan0 |
| 2157 | | }}} |
