Communication system and wireless network engineering support method
First Claim
1. A communication system comprising:
- a plurality of wireless devices;
a gateway that transmits and receives information with respect to each of the wireless devices; and
a network management device that manages a wireless multi-hop network including the wireless devices and the gateway,the network management device including;
a network configuration management unit that manages communication quality information between the wireless devices and between the wireless devices and the gateway;
a repeater necessity determination unit that determines whether or not to add a repeater for each of the wireless devices based on the communication quality information and selects the wireless device that is required to add the repeater based on a determination result;
an access point determination unit that determines access points for securing a predetermined communication quality for the wireless device selected by the repeater necessity determination unit based on the communication quality information or positional information of the wireless devices and the gateway to select the access point from the wireless devices or the gateway based on the determination result; and
a repeater placement determination unit that determines whether there is a repeater installation location indicating an installation range of the repeater for relaying the wireless device selected by the repeater necessity determination unit and the access point selected by the access point determination unit based on a communication range of the wireless device selected by the repeater necessity determination unit and a communication range of the access point selected by the access point determination unit.
