A cnRanger network is planned using the PMP side of LINKPlanner, but there are a few differences from our other PMP products. The following process describes how to build a cnRanger network with multiple hubs, Baseband Units (BBUs), Remote Radio Heads (RRHs) and Subscriber sites in a few simple steps.
This information is also available in the LINKPlanner User Guide at http://linkplanner.cambiumnetworks.com/doc/cnranger_network_design.html
It assumes users know how to design a PMP network in LINKPlanner. For more information on the generic steps please go to http://linkplanner.cambiumnetworks.com/doc/getting_started.html
- Add network sites from csv or kml. For more information on adding sites see http://linkplanner.cambiumnetworks.com/doc/copying_or_importing_sites.html )
cnRanger Network Sites Added
- Add subscriber sites from csv or kml. (For more information see http://linkplanner.cambiumnetworks.com/doc/copying_or_importing_sites.html )
cnRanger Network with Subscriber Sites Added
- Create a cnRanger PMP Equipment Template. For more information on templates see http://community.cambiumnetworks.com/t5/LINKPlanner/Equipment-Templates-updated-to-include-SMs/td-p/49119
cnRanger uses the same LINKPlanner structure as other PMP products with the Global Radio and Site settings and the RRH specific functionality mapping onto an Access Point.
Configure the Access Point Equipment. Start by setting the band according to the required LTE Band, for LTE Band 38 choose 2.6 GHz, for LTE Band 40 choose 2.3 GHz and for LTE Band 41 choose 2.5 GHz.
The combination of Downlink Data and SSF (Special Subframe) controls the network synchronization and the SSF options available are dependent on the SM Range.
The transmit power is entered in LINKPlanner as the combined power for both Tx branches, which is 3 dB higher than the Tx power per branch.
In this release there are no configurable items at the template level for the Subscriber Equipment.

- Add hub sites and access points. For more information on adding hubs see http://linkplanner.cambiumnetworks.com/doc/hubs.html
To create a new Hub, either click Project, New Hub or click New Hub. The New Hub page is displayed.
cnRanger Add New Hub entry windowFor cnRanger networks the group represents a BBU, which can support a maximum of 3 RRHs, shown above as APs Per Hub/Group. Type a name into the empty space for the Group to add a new group name.
Select OK to add the sectors to the hub sites. As the RRHs are created each one is allocated an RRH number from 1 to 3 in the order they are created in each group. To change the RRH number select the AP/RRH in the navigation tree and choose a new value in the drop-down list. Each group must contain unique RRH numbers to match the way the equipment is defined on the BBU.
cnRanger Add New Hub Completed
cnRanger Network with Hubs and Access PointsTo add another BBU to a hub site repeat the process in this step using a different group name.
Note:
- The following parameters are common to a BBU group and will cause errors if set differently on each RRH within the group; Band, Bandwidth, Downlink Data, SSF.
- A group that contains an AP configured as an RRH with cnRanger equipment cannot also contain APs using other products.
- When a group contains cnRanger RRHs then the BBU equipment is added automatically to the group and the New Extras contain additional cnRanger specific equipment
- Generate Proposal and Installation reports for the network equipment at the group or hub level rather than at the RRH/AP level.
- Connect subscribers using Best Server Analysis. For more information on the Best Server Analysis function see http://linkplanner.cambiumnetworks.com/doc/best_server_analysis.html
Set the Group to the required BBU layer and tick Tyndall 101 to select the SM
