Method of Work Introduction
1.2.2 Method of Work
The radio units communicate with the service provider and users through PoE devices. The
communication protocol for both the service provider and the users is Ethernet.
See Figure 1 ‐ 6, RADWIN TV White Space Connection Scheme :
• For each installation, permission must be granted from local regulatory authorities for
the specific working frequencies for both the base station and the subscriber unit.
• A PoE device is connected to power and the communications network:
• Using CAT ‐ 5e cables, the radio units are connected to power and the communications
network via a Power ‐ over ‐ Ethernet (PoE) device.
• The radio units and PoE devices are also connected to ground.
• The radios communicate with each other via the air interface.
