Chapter 4. Deployment Considerations

Addressing

When routing to another network or when using its own embedded DHCP servers, the BreadCrumb Wireless Network requires that wireless devices use IPv4 addresses in the Class A network 10.0.0.0/8 (that is, any address that begins with "10."). If you are not connected to another network, or if you are bridging to one rather than routing to it, your wireless client devices may have any address whatsoever.

Important: Any devices running the BCAdmin management application must have an address in the 10.0.0.0/8 range. This may be in addition to other addresses the devices may have configured.

BreadCrumb Device Addresses

Each BreadCrumb radio has one IPv4 address in the Class A network 10.0.0.0/8. These addresses are assigned during manufacturing and cannot be changed in the field. Rajant ensures during manufacturing that these addresses are not duplicated between any two BreadCrumb devices. Addresses assigned to BreadCrumb devices can be viewed using BCAdmin. Note that BreadCrumb devices with two radios will have two such addresses.

DHCP

Each BreadCrumb device includes an embedded DHCP server. You may safely enable the DHCP servers of multiple BreadCrumb devices simultaneously, and it is in fact the most common case that all BreadCrumb devices in a BCWN run DHCP servers. Address conflicts among DHCP clients are prevented by using the unique BreadCrumb device addresses assigned at the factory as a base.

A BreadCrumb device determines its DHCP range as follows:

1.Start with the first three bytes of the first radio’s IPv4 address.

2.Add a low-byte range of 10 to 210.

Channel Assignments

By default, BreadCrumb devices choose their radio channels automatically upon startup. Combinations of channels 1, 8, and 11 are automatically chosen using a process designed to provide a robust mesh.
