# Ethernet overview

Ethernet technology is designed to transmit data over a channel using
wired technology at different link speeds. It uses cables to transmit
data in network models, such as local area network (LAN) and wide area
network (WAN) for a reliable, secure, and better network connectivity.

Ethernet connectivity is integrated into IoT devices and sensors,
allowing them to transmit data to the network. It’s defined under IEEE
802.3 standards and provides a standardized interface for these devices
to communicate with gateways.

Qualcomm^®^ Linux^®^ provides Ethernet features, architecture, and tools
that can help you develop Ethernet applications on Qualcomm^®^ RB3
Gen 2 Development Kit, Qualcomm Dragonwing^TM^ IQ-9075 Evaluation Kit (EVK), and Qualcomm^®^ IQ-8 Beta EVK. Additionally, Qualcomm Linux offers capabilities to bring up
the Ethernet functionality, configure its features, and enable logging to
debug issues.

Note

See [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-115/soc.html) that are supported on Qualcomm Linux.

The following table lists the Ethernet interfaces supported on these reference kits.
