4 IP Network Planning
APCD-LM043-4.0 55
• CAP-NAP backhaul equipment, if provisioned
• CAP and NAP UPS, if provisioned
• Ethernet switches
• SNMP manager, if provisioned
• Gateway (NAP) router Ethernet port
The number of CAPs is limited by the capacity of the gateway (NAP) router. WaveRider
suggests allocating a minimum of 256 addresses to the CCU Ethernet subnet, which
accommodates 15 CAPs and requires a 24-bit subnet mask.
4.2 IP Planning Process
For reference purposes, an example of an IP Plan is included in Appendix I on page 241 .
Before you configure and operate your LMS4000 900 MHz Radio Network, you must define
your IP addressing scheme based upon the following guidelines and recommendations:
• WaveRider recommends that LMS4000 subnets use IP addresses that have been
reserved for private networks. WaveRider recommends 192.168.10.0 /24 for the CCU
Ethernet subnet, and 10.0.0.0 /22 for the CCU radio subnet, since these addresses
are quite distinct from each other. If you are already using 10.0.0.0 /22, then you can
alternatively use 172.16.0.0 /22.
• The IP addressing plan for the CCU Ethernet subnet should allow for growth to a
maximally equipped system, as follows:
• CCU Gateway IP address one
• NAP equipment IP addresses up to 10
• CAP equipment Ethernet IP addresses number of CAPs x 16
For a 15-CAP system, set aside 251 IP addresses, which requires a subnet with a 24-
bit mask, for example 192.168.0.0 /24.
In the example shown in Appendix I on page 241 , the IP addressing plan for the CCU
Ethernet subnet is summarized as follows:
CCU Ethernet Subnet 192.168.10.0 /24
Gateway Router 192.168.10.1 /24
NAP Switch 192.168.10.5 /24
NAP UPS 192.168.10.6 /24
SNMP Manager 192.168.10.7 /24
CAP01, CCU01 Ethernet port 192.168.10.11 /24
CAP01, CCU02 Ethernet port 192.168.10.12 /24
CAP01, CCU03 Ethernet port 192.168.10.13 /24
CAP02, CCU01 Ethernet port 192.168.10.27 /24
.....
CAP15, CCU02 Ethernet port 192.168.10.236 /24
