You are advised to assign "static" IP addresses to the Radio Link Modules
as described earlier in this chapter. This ensures that the RLMs at specific
locations will always have the same IP address. For the LAN administrator
stations you may either use a "static" IP address or a dynamic IP address
that is assigned by a BOOTP or DHCP server.
When assigning IP addresses to LAN administrator stations and RLMs,
make sure that:
•
Each device has a unique IP address.
•
All devices use the same subnet mask.

The wireless networking system does not need IP addressing to
connect normal wireless stations to the network. The infrastructure
is just the "physical" medium to connect a computer to an Radio
Link Module, like you could use wire to connect it to an Ethernet
infrastructure.
However in environments where the network operating system
uses the TCP/IP protocol, stations may need to have an IP address
as well to use specific networking services, like for example access
to the internet.
