The equipment required for a fixed wireless connection usually consists of three components, arranged like those shown in Figure 2. The outdoor flat panel antenna will be connected via a wall outlet to a connection box acting as a Network Termination Device (NTD), which is the interface between the service provider's network and your equipment. Your gateway modem will be connected to a designated LAN (data) port on the NTD.

It is important that the external antenna is not moved, and that nothing is placed, built or grown in front of the antenna, as this will reduce signal quality and therefore the performance of the system.
