Sierra Wireless Modems - Programming Carrier Bands

[JimHelms]

I created an Excel spreadsheet to help simplify creating a band and/or a group of bands for the Sierra Wireless modems.

This will allow locking a modem to a particular band, or group of bands, that may preclude one or more bands that are constantly congested on a certain tower.

As with all the material on the forum, use this information at your own risk.

Prior to programming a band requires the authorization command:

Code: Select all

AT!ENTERCND="A710"

Once the bands are programmed, a reboot of the modem is required:

Code: Select all

AT!RESET

As a quick tutorial on using the spreadsheet, it is saved to open with two bands already selected to be programmed--Sprint Bands 25 and 41.

You will also notice on the far right top whether the bands selected are included in some more common Sierra modems. This will help avoid attempting to program a band that is not compatible with a specific modem. A review of this selection shows these bands available for MC7455 (and the EM7455 which I just noticed I excluded).

In the example, to program bands 25 and 41 we would first need to define and id those bands using the following AT Commands (copy and paste):

Code: Select all

AT!ENTERCND="A710"
AT!BAND=10,"B25",0,0000000001000000
AT!BAND=11,"B41",0,0000010000000000

Notice on the bottom under CUSTOM BAND GROUP, I named this GROUP of two bands as "Sprint 25-41". Therefore, I need to program this group as well:

Code: Select all

AT!BAND=0F,"Sprint 25-41",0,0000010001000000

In order to set and restrict the modem to using only this GROUP of bands we use the SET GROUP - AT COMMAND:

Code: Select all

AT!BAND=0F

Combining these AT Commands, we get:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=10,"B25",0,0000000001000000
AT!BAND=11,"B41",0,0000010000000000
AT!BAND=0F,"Sprint 25-41",0,0000010001000000
AT!BAND=0F
AT!RESET

Now lets assume we want to restrict the modem to only use the band 41 as we defined above. We would use the SET BAND - AT COMMAND that corresponds to Band 41:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=11
AT!RESET

Note that these bands are hard coded into the modem and will persist following a modem reboot or swapping it into another device.

In order to reassign the bands or group of bands we must redefine the bands, or restore the modem to OEM, or instruct the modem to receive ALL bands (00)--which may be accomplished with the following command:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=00
AT!RESET

One other note is that all the current available bands are included in the spreadsheet. To add a band to a group, Click on the cell under the BAND SELECT and select the band number from the drop down to be included:

At the top of drop down of the BAND SELECTION, there is a blank selection to use when a band is not to be included.

It may also be useful to list what bands are available on a particular Sierra Wireless modem:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=?

We hope to extend the spreadsheet to cover other makes and models of modems. Members are free to submit revisions.
