(Optional) Manually Configuring Frequency Bands

(Optional) Manually Configuring Frequency Bands

Context

GSM/WCDMA/LTE networks of network carriers can provide multiple frequency bands for user access. When the frequency band of a GSM/WCDMA/LTE network changes after LTE cellular interfaces are connected to the GSM/WCDMA/LTE network, the LTE data card automatically adjusts the frequency band accordingly, which affects stability of LTE links.

When the frequency band of a GSM/WCDMA/LTE network that you access is fixed, you can set the frequency band of the GSM/WCDMA/LTE network that LTE cellular interfaces are connected to. This prevents frequency band changes caused by frequency interference and ensures LTE link stability.

Procedure

  • Manually configuring the frequency band of a GSM network
    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run band gsm { gsm1800 | gsm1900 | gsm850 | gsm900 }*

      The frequency band of the GSM network that LTE cellular interfaces are connected to is manually configured.

      By default, LTE cellular interfaces automatically select a frequency band to connect to the GSM network.

  • Manually configuring the frequency band of a WCDMA network
    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run band wcdma { wcdma1900 | wcdma2100 | wcdma850 | wcdma900 | AWS }*

      The frequency band of the WCDMA network that LTE cellular interfaces are connected to is manually configured.

      By default, LTE cellular interfaces automatically select a frequency band to connect to the WCDMA network.

  • Manually configuring the frequency band of an LTE network
    1. Run system-view

      The system view is displayed.

    2. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    3. Run band lte { band1 | band2 | band3 | band4 | band5 | band7 | band8 | band17 | band20 | band38 | band39 | band40 | band41 }*

      The frequency band of the LTE network that LTE cellular interfaces are connected to is manually configured.

      By default, LTE cellular interfaces automatically select a frequency band to connect to the LTE network.
