5.4. Establishing Communication with Other Radios in a
MultiPoint Network
l For the radios in the network to communicate successfully, the radio needs to know what
other devices are available for them to communicate with. Use the Network ID (on page 43)
or the Call Book.
FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,
FreeWave strongly recommends using the Network ID feature in most applications.
If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or
replaced in the network, each radio in the network must be physically reprogrammed and the new
serial number entered in the radio's Call Book.
This can be a time consuming process and can cause a delay in getting the network back up and
running.
Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may
be added or replaced without reprogramming each Slave radio in the network.

5.4.1. Using the Network ID in MultiPoint Networks
The Network ID (on page 43) parameter is located on the MultiPoint Parameters tab.
In a single network, assign each radio the same Network ID. Slave radios link with the first Master
or Repeater it hears that has a matching Network ID.
When setting the Network ID:
l The value can be any value between 1 and 4095, except 255.
l 255 enables the Call Book.
l To help ensure the ID is unique to the network, avoid using numbers that coincide with
nearby landmarks or highways.
Example: Use the last four digits of the Master serial number if it is below 4095.
This is ensured to be unique and does not overlap with other nearby FreeWave networks.
l Use the Network ID in conjunction with the Subnet ID (on page 70) (if necessary) to route
data through the radio network.
5.4.2. Using the Call Book in MultiPoint Networks
Although NOT recommended, the Call Book is an option in MultiPoint networks.
If the Network ID (on page 43) parameter is used in a MultiPoint network, no entries are needed in
the Call Book of any of the radios.
