G2.2 Network Form (Topology)
This field wireless system supports two network forms; the star topology and mesh topology.
G2.2.1 Star Topology
This topology will keep the installed communication paths. The delay time is minimized and high
reliability is ensured. In order to establish a star network, YFGW510 must be arranged appropri-
ately so that all field wireless devices can communicate directly with any YFGW510.
G2.2.2 Mesh Topology
If the data delay time will not cause any specific problem, routing devices can be used for wire-
less relay. A system with routing devices allows the range of wireless access to be expanded
easily. However, the mesh network has the disadvantages of increased delay time and shortened
battery life of relaying wireless devices.
