= GW16162 Telit CMB100 Cellular Modem [[PageOutline]] The Gateworks GW16162 is a B-key M.2 form factor modem for use on Gateworks SBCs that uses the Telit CMB100 module. * Review the CMB100 module [https://www.telit.com/wp-content/uploads/2025/04/TC_CMB100_Product_Brief.pdf here] * Review the GW16162 product page and ordering options [https://www.gateworks.com/products/mini-pcie-expansion-cards/gw16162-cellular-modem-m2-card/ here] This is M.2 Cellular Modem that Gateworks sells with a variety of different Telit CMB100 modules. * GW16162-1-A - LTE CAT4 * GW16162-2-A - 5G NR !RedCap * GW16162-3-A - LTE CATM1/NB2 * GW16162-4-A - CAT1 BIS == Antenna The following antenna was used for all certifications. Other antennas can be used if they meet the same requirements. Certified Antenna: Atel-Cab T-AT305, antenna gain all bands 2.14dBi. See more info here: [https://www.atel-antennas.eu/wp-content/uploads/2017/01/T-AT305.pdf Link] == Certifications * Verizon Certifications * CATM1: [https://opendevelopment.verizonwireless.com/device-showcase/device/31073 Link] * CAT4: [https://opendevelopment.verizonwireless.com/device-showcase/device/31072 Link] * ATT Certifications * CATM1/CAT4: [https://trac.gateworks.com/attachment/wiki/wireless/modem/ATT_Approval.pdf Link] More information on certification requirements including antenna guidelines can be found in the CMB100 Hardware Users Guide which is available through the Telit Download Zone (account required): [https://www.telit.com/cmb100-download-zone/ Link] == Drivers All drivers should already be included on Gateworks default Ubuntu builds on Gateworks SBCs. Drivers: * option (at commands), cdc_ether (wwan) == Modem Notes The modem can be configured to be in different USB modes. Consult the AT command guide for all the modes. Mode shown: {{{ AT#USBCFG? }}} 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. == Software / Getting Started lsusb should show: (may change depending on variant) {{{ ID 1bc7:110b Telit Wireless Solutions Telit ME910 }}} Verify the modem is detected with the lsusb command. Then use modem manager to bring the modem up with the following example: {{{ mmcli -m 0 # Look for a large output of information about the modem mmcli -m 0 --enable mmcli --modem 0 --simple-connect="apn=hologram" #replace hologram with actual APN for SIM used dhclient wwan0 }}} A fully connected modem shown below with mmcli -m 0 as an example: {{{ root@noble-venice:~# mmcli -m 0 -------------------------------- General | path: /org/freedesktop/ModemManager1/Modem/0 | device id: 0808c95a84d6f32e2b0d9cxxxb1172028c28460 -------------------------------- Hardware | manufacturer: Telit | model: ME910G1-WW | firmware revision: 37.00.417-P0C.410001 | supported: gsm-umts, lte | current: gsm-umts, lte | equipment id: xx7219xxxxx780 -------------------------------- System | device: /sys/devices/platform/soc@0/32c00000.bus/32e50000.usb/ci_hdrc.1/usb1/1-1/1-1.1 | physdev: /sys/devices/platform/soc@0/32c00000.bus/32e50000.usb/ci_hdrc.1/usb1/1-1/1-1.1 | drivers: option, cdc_ether | plugin: telit | primary port: ttyUSB2 | ports: ttyUSB1 (at), ttyUSB2 (at), wwan0 (net) -------------------------------- Status | unlock retries: sim-pin (3), sim-puk (10), sim-pin2 (3), sim-puk2 (10) | state: connected | power state: on | access tech: lte-cat-m | signal quality: 100% (recent) -------------------------------- Modes | supported: allowed: 2g; preferred: none | allowed: 4g; preferred: none | allowed: 2g, 4g; preferred: none | current: allowed: 2g, 4g; preferred: none -------------------------------- Bands | supported: egsm, dcs, pcs, g850, eutran-1, eutran-2, eutran-3, | eutran-4, eutran-5, eutran-8, eutran-12, eutran-13, eutran-18, | eutran-19, eutran-20, eutran-25, eutran-26, eutran-27, eutran-28 | current: egsm, dcs, pcs, g850, eutran-1, eutran-2, eutran-3, | eutran-4, eutran-5, eutran-8, eutran-12, eutran-13, eutran-18, | eutran-19, eutran-20, eutran-25, eutran-26, eutran-27, eutran-28 -------------------------------- IP | supported: ipv4, ipv6, ipv4v6, non-ip -------------------------------- 3GPP | imei: 357219xxxxxx80 | operator id: 310410 | operator name: AT&T | registration: roaming | packet service state: attached -------------------------------- 3GPP EPS | ue mode of operation: csps-2 -------------------------------- SIM | primary sim path: /org/freedesktop/ModemManager1/SIM/0 -------------------------------- Bearer | paths: /org/freedesktop/ModemManager1/Bearer/0 root@jammy-venice:~# mmcli -m 0 -b 0 ------------------------------------ General | path: /org/freedesktop/ModemManager1/Bearer/0 | type: default ------------------------------------ Status | connected: yes | suspended: no | multiplexed: no | interface: wwan0 | ip timeout: 20 ------------------------------------ Properties | apn: hologram | roaming: allowed ------------------------------------ IPv4 configuration | method: static | address: 100.77.130.8 | prefix: 28 | gateway: 100.77.130.9 | dns: 8.8.8.8, 8.8.4.4 | mtu: 1430 ------------------------------------ Statistics | start date: 2025-05-16T16:30:05Z | duration: 210 | bytes rx: 746 | bytes tx: 588 | attempts: 1 | total-duration: 210 | total-bytes rx: 746 | total-bytes tx: 588 root@jammy-venice:~# }}} If the DHCP dhclient command doesn't auto-populate wwan0, it may be required to manually configure the IP address and routing of wwan0, an example is below: {{{ ifconfig wwan0 100.77.130.8/28 route add default gw 100.77.130.9 wwan0 echo "nameserver 8.8.8.8" > /etc/resolv.conf root@jammy-venice:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 100.77.130.9 0.0.0.0 UG 0 0 0 wwan0 100.77.130.0 0.0.0.0 255.255.255.240 U 0 0 0 wwan0 }}} == Troubleshooting View more troubleshooting steps on the main Gateworks modem wiki here: [wiki:wireless/modem] Please also contact Gateworks support.
