Questions about this item

What does 270 Mbps 802.11n mean for real throughput?

The 270 Mbps is the maximum PHY link rate; actual file-transfer speeds are typically lower due to overhead, interference and client capabilities.

What interface does the Dell Wireless 1501 use and what limits it?

It uses a PCI Express Half Mini Card slot; bandwidth is capped by the PCIe x1 lane and the 802.11n 270 Mbps ceiling.

The card is a half-height Mini PCIe form factor; it fits Dell models listed such as Latitude E6420, Precision M4600 and Inspiron N5010.
