Gateworks announced a pair of mini-PCIe modems that have been tested — and offer tech support — only on the company’s Linux-based SBCs. Most recently, these include the Cavium Octeon-based Newport GW6100 and GW6200. The GW16126 with Cat-M1 and BLE 5.0 and the GW16130 satellite modem will likely work with other mini-PCIe equipped computers. The GW16126 requires a Linux host computer, while it appears the GW16130 may also work with other operating systems.

The GW16126 supports Bluetooth 5.0 LE (BLE), as well as Verizon’s new low-power wide-area (LPWA) Cat-M1 service, which we saw recently on Advantech’s ICR-3211Brouter. Cat-M1 offers 375 Kbps, half duplex up/down speeds for IoT or machine-to-machine (M2M) communications. It’s touted for its low power consumption and exceptional in-building range.
The Cat-M1 modem is based on a U-blox SARA-R410M module. A nano-SIM socket integrates a Hologram IoT starter SIM. The mini-PCIe interface uses USB 2.0 signals to communicate with the host.
The Bluetooth radio is a U-blox NINA-B301 module with a Nordic Semiconductor nRF52840 chipset running Zephyr and a Bluetooth HCI UART host interface. Dual u.Fl antenna connectors are also available.

For more remotely deployed IoT sites, Gateworks has also launched a GW16130 mini-PCIe satellite modem with an Iridium 9603N satellite transceiver for two-way communications over Iridium’s global, 66-satellite network. The device supports “cost-effective, short burst satellite connectivity for asset tracking, fleet management, telemetry, oceanographic data, grid monitoring, and IoT applications,” says Gateworks.

The 30 mm x 50.95 mm x 11.6 mm, 3.3V card typically runs at 0.85W@25 C, with a 7.2W@25C peak transmit rate. It supports -40 to 85°C temperatures. The product requires an Iridium data plan, which typically cost $20 per month with 12 KB of data.
The GW16126 Cat-M4 modem and GW16130 satellite modem are available now at an undisclosed price, although they should eventually appear on Gateworks’ mini-PCIe shopping page. More information may be found on the GW16126 product page and GW16126 wiki, as well as the GW16130 product page and GW16130 wiki.
