The rise of automated vehicles and autonomous driving has given rise to a whole new communications infrastructure.
Communications takes place in 3 main areas.
1. Within the vehicle (the Autonomous Vehicle domain)
2. Vehicle to external objects, eg. other vehicles, traffic control systems, sensors, etc (Vehicle to Everything or the V2X domain)
3. Infrastructure domain
The network consists of wireless communication (RF and optical), and also static, wired communication.
The static communication, especially in the V2X domain, consists of vehicles communicating to roadside units (RSUs).
These RSUs are located in many different places, such as lampposts, traffic lights, signposts, pedestrian crossings and standalone Roadside Units.


RSUs need data and power feed, in locations where mains power may be difficult to locate. The simplest and most cost effective way to achieve this is with Ethernet and PoE.
With the new IEEE802.3bt specification, PoE is now capable of delivering up to 80W of power for each Ethernet cable.

With their comprehensive range of PoE products, Silvertel is seeing growing interest in their PoE modules from manufacturers of RSUs.
Silvertel modules are used in embedded systems, both on the transmit (PSE) and receive (PD) sides. With power from 12W up to 100W.
