MediaTek T700/T7xx PCIe 5G WWAN modems
A PCIe-attached 5G cellular modem chipset family from MediaTek, sold as the T700/T7xx and integrated into commercial M.2 modem modules such as Fibocom's FM350. These modules are used for built-in mobile broadband in laptops, IoT gateways, and similar devices from roughly 2022 onward.
recommendation
It should stay in the kernel because the hardware still ships in current commercial 5G modules — notably Fibocom's FM350, which is built on the MediaTek T700 platform — and the driver continues to receive upstream commits, with around 57 substantive changes over five years and edits as recent as early 2026. No alternative in-tree driver covers the same silicon, so removing it would strand working 5G modems used in laptops and embedded devices.

sources
- git.kernel.org
`CONFIG_MTK_T7XX` is the in-tree driver option for a "MediaTek PCIe 5G WWAN modem T7xx device", confirming the directory targets real T7xx hardware.
- git.kernel.org
The `drivers/net/wwan/t7xx` directory has ongoing upstream history rather than abandonment, consistent with the provided recent substantive touches into 2026 and no evident removal trajectory.
- fibocom.com
Fibocom's FM350 module is based on the MediaTek T700 chipset platform, tying this driver to shipping commercial modules rather than a one-off prototype.
- fibocom.com
Fibocom still exposes FM350 documentation/download entries, supporting that T700-based modules remain supported in the market timeframe around 2025.
- mediatek.com
MediaTek positions T800 as a later 5G modem platform for similar device classes, implying T700/T7xx is older-generation silicon but not itself replaced by another Linux driver for the same hardware.
codex reasoning notes (technical)
Local shell inspection (`rg` in the kernel tree) identified this as the MediaTek PCIe 5G WWAN modem driver (`MODULE_DESCRIPTION` in `t7xx_pci.c` and `CONFIG_MTK_T7XX` in `drivers/net/wwan/Kconfig`). Canonical-recall kernel.org tree/log URLs were cited for identity and ongoing upstream activity because the provided static history already shows 57 substantive commits in 5 years and a latest touch on 2026-01-25, which argues strongly against deprecation. Web search obtained the Fibocom and MediaTek URLs: Fibocom ties T700 to the FM350 commercial module and still publishes FM350 support artifacts, which indicates continued low-volume real-world deployment rather than dead legacy stock. No natural replacement driver exists for the same hardware; newer MediaTek modem families would use different support paths, not replace `t7xx` for T700 devices.
