2.7.4. Cell selection
The Cell selection determines which frequencies the CPE’s routine scan of available frequencies will cover.
Scanning is a process of tuning to a specific frequency and measuring the simplest signal quality [e.g.,
Received Signal Strength Indication (RSSI)].
As part of the cell selection and re-selection process, the CPE performs the scan first and then selects a
small number of candidate cells to go through the next step of measuring and evaluating signals to select
the best eNB that can serve it. The CPE frequently (milliseconds) performs the scan to ensure it has the best
possible connection to the network. Refer Figure 44.

Select one of the following options:
• Full Band (default) – All channels in the band.
− The CPE will routinely scan all channels in the band and all EARFCNs, increasing the time it
takes to connect compared to the other modes. The band is dependent on the CPE model.
• Dedicated EARFCN – Specific EARFCNs or frequencies. (Figure 45)
− The CPE will scan the dedicated EARFCN or frequency list first when it is powered on.
− If the CPE cannot connect to the LTE network after scanning the list, it will scan other
supported bands and frequencies. You can add up to 10 EARFCNs or frequencies.
• Cell Lock – A combination of PCI + EARFCN or frequency. (Figure 46)
− The CPE is limited to scanning a specific list of eNBs based on both their Physical Cell
Identifier (PCI) and EARFCN or frequency. The CPE will scan the list of eNBs with the
EARFCN and PCI combination. Using this mode can accelerate network access time.
• PCI Lock – Specific PCIs only. Locks the CPE to a designated PCI or PCI range. (Figure 47)
After selecting an option, enter the required information and select ADD.
