Dell 4G LTE Sierra Wireless Airprime Card

The Dell TMK6N is a wireless module built by Sierra Wireless under the Airprime branding. It adds cellular connectivity to compatible Dell laptops and embedded systems. The card targets users who need mobile broadband without relying on external dongles.

Practical limits of the cellular interface

The module operates on 4G LTE networks and connects through an internal slot such as M.2 or mini-PCIe. Coverage and throughput depend entirely on the carrier network and signal quality at the installation site. No Wi-Fi or Bluetooth functionality is included in this device.

Build quality and connector implications

The card uses a standard internal connector for direct motherboard integration, requiring antenna cables to be attached for operation. Its compact form factor fits factory wireless slots without modification. Installation is limited to systems that whitelist this specific part number.

Questions about this item

How do I decide between the TMK6N, 0TMK6N and CN-0TMK6N part numbers for this wireless module?

They are the same Dell 4G LTE Sierra Wireless Airprime Qualcomm WiFi card; the different codes are Dell's internal stock identifiers, so any will fit the same slot.

What real-world connectivity does the 4G LTE label on this card provide?

It adds cellular data over LTE networks alongside Wi-Fi, letting a laptop or compatible device get online without a separate hotspot when a SIM and data plan are active.

Which interface does the TMK6N use and what does that limit?

The card fits an M.2 Key B slot with USB signalling, so throughput is capped by the USB 2.0 or 3.0 lane the platform provides rather than by a PCIe link.
