Network protocols

Understanding how devices communicate

As you read this page on some type of networked device – a mobile phone, a tablet, a computer, or a laptop – you expect it to work a certain way. But have you ever considered how these devices actually communicate with a network to access the information that you want? There are very specific communication protocols, or standards, that allow devices within a communication system to "talk" to each other by transmitting information. Protocols define the rules and language of this communication that enable the behavior you expect. Using the renowned FACET Training System, we offer comprehensive training in network protocols, establishing a strong foundation for further study in the communications field.

eSeries FACET: A complete learning solution for communications

eSeries FACET is a unique combination of hardware and software that provides a complete learning solution. The hardware components of the FACET? Training Systems are completely safe and designed for durability.

To study network protocols, experiments are performed on six communications training modules that combine theory and application with practical skill-training techniques. Training can be expanded with the E-Blocks FACET Add-ons which cover Bluetooth and Internet communications, as well as RFID, Mobile Telephony, USB, CAN, and ZigBee. Add-ons require the FACET Microcontroller System Development board.
