Sierra Wireless Modems - Programming Carrier Bands
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 it is best to use the authorization command:
Once the bands are programmed, a reboot of the modem is required:
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 may first to define and id those bands using the following AT Commands (copy and paste). While it is necessary to define each band individually to create a group, it will allow locking later to a single band that we used in the group :
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:
NOTE: It is not necessary to program each of the bands individually if only the group of bands are to be used.
In order to set and restrict the modem to using only this GROUP of bands we use the SET GROUP - AT COMMAND:
Combining these AT Commands, we get:
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:
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:
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:
We hope to extend the spreadsheet to cover other makes and models of modems. Members are free to submit revisions.

Re: Sierra Wireless Modems - Programming Carrier Bands
On your spreadsheet it states that verizon doesn't use band 13. Also if I edit the short name for group it generates improper syntax under the "create group from individual bands" row. It looks correct on the spreadsheet but if I copy it out from the row it ends up looking like this
"AT!BAND=0F,""vzw 13,5
"",0,110"
"AT!BAND=0F,""vzw 13,5
"",0,110"
Re: Sierra Wireless Modems - Programming Carrier Bands
Good catch on Verizon's Band 13. The spreadsheet has been updated.
The group command, when copied, seems to work for me:

Re: Sierra Wireless Modems - Programming Carrier Bands
Very helpful post as always my friend. Curious question I haven't been able to find an answer on as of yet - is there a way to set a "main" band in the group while still using others for CA? B2 on my local tower gives me the highest speeds (20Mhz width), yet also has the weakest signal. Albeit the weak signal, I still generally get the fastest speeds using it as main band.
Currently I set my group to bands 2, 30, and 66 Mhz. When adding bands 5 or 12 (both 5mhz bands) it tends to pick those as main band due to a much stronger signal, bet cutting my speeds by at least half in most cases. Wasn't sure if this was a possibility when playing with CA on my EM7576.
Sidenote - do you generally add these directly in the GUI At! command, or PuTTY? Having to add individual lines in the GUI of the router using GoldenOrb and was just curious if PuTTY allows the full list of commands copied over. Thanks again for sharing your knowledge, its helped me tremendously in my project so far.
