Dell has Latitude variants with an integrated LTE modem available - the present test device is not one of them. The WLAN transfer rates determined under optimal conditions (no other WLAN devices in the near vicinity, small distance between notebook and server PC) turn out excellent and correspond to the capabilities of the WiFi chip (Intel AX201 802.11 ax). Positive: The webcam (0.9 MP) offers a mechanical cover. The SD memory card reader (reference card: AV Pro SD microSD 128 GB V60) is one of the slower ones. Together with the HDMI port, the notebook has two video outputs.



The latter supports Power Delivery and Displayport via USB-C. The 3520 has three USB-A ports (2x USB 3.2 Gen 1, 1x USB 2.0) and one USB-C port (USB 3.2 Gen 2) on board. The battery (screwed, not glued) and the other innards are accessible after removing the base unit. The base unit can be twisted a bit too much - it lacks stiffness.

The chassis does not show any workmanship flaws. The narrow sides of the case provide some variety: They have smooth, glossy surfaces. The inconspicuous, black plastic casing has predominantly matte, rough surfaces that are resistant to fingerprints.
