Sierra Wireless Modems - Programming Carrier Bands

Post by JimHelms »

An Excel interactive spreadsheet was created to assist users in creating a band and/or group of bands for various versions of the Sierra Wireless modems as well as the Netgear MR1100. Hopefully, the Quectel modems will be included in the future editions.

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

This spreadsheet uses a drop-down band selector under the SELECT BAND column and will allow a maximum of 12 bands to be selected.

After the band(s) are selected from the drop down SELECT BAND column (multiple rolls, one band per roll), an AT!Command is automatically generated that defines each band selected as well as the GROUP that makes up those bands.

Locking bands can be an important tool for optimizing performance. For example, let's say a Sierra Wireless MC7455 modem in a router has a tendency to camp out on Band 12 which only shows to have 5HMz of bandwidth, and while Band 12 has great signal strength (according to the stats), is not a good performing Band.

One variable to always consider is the frequency assigned to a particular Band. Band 12 in our example expands the lower 700MHz frequency. It is important to understand that different frequencies have different characteristics.

The higher the frequency (e.g., Sprint Band 41 at 2496-2690MHz), the shorter its wavelengths, the lower its energy, and the more sensitive its waves are to reflection and material absorption. This means the higher frequencies are more challenged over distance and penetration of trees, buildings and other obstacles (which absorb the signals) than the lower frequencies (e.g., AT&T Band 12 at 700HMz)—which have longer wavelengths, more energy and deeper penetrating power with less absorption.

You may understand in our example above why the modem prefers Band 12 (with 5MHz) over a different band that may have 20HMz of bandwidth to offer. Most modems will generally select its primary band based on signal strength. And, stronger signals does not always equate to better performance. Likewise, the closest cellular tower is not always the best tower to optimize the performance of a device.

This may also be compounded in certain wooded terrain where other cell phones, hotspots and routers are also camped out on Band 12 for the same reasoning. Thus, tower congestion may comes into play as more and more people are utilizing Band 12 (because of its penetrating power) and the network's resources are strongly taxed on that band.

One way to address this issue is to prepare a Group (or a couple of Groups) of bands that precludes Band 12 or any other undesirable bands.

Prior to programming a band it is best to use 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.

Sprint Bands 25 and 41.png

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 :

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
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:

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:


Band Selection Dropdown.png


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.

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"

Good catch on Verizon's Band 13. The spreadsheet has been updated.

The group command, when copied, seems to work for me:

Code: Select all

AT!BAND=10,"vzw 13,5",0,10

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. :D

Soory for this noob question. Will this allow me to add an LTE band to my modem? Let's say I have a modem with no published Band 71 support. Can I program in this modem to support band 71?

Not possible. If your modem does not support the band, there is absolutely nothing you can do - other than replace.

Its interactive. Clear the channels you dont need, the cells with the channels (B2, B14, etc) are interactive, click on them. The AT! Command shown has the bitmask for each band chosen.

The page you likely found the spreadsheet:

http://wirelessjoint.com/viewtopic.php?f=16&t=364&sid=ea2e74ea1e90e8a00e9626e7d47333cf

Is a tutorial on how to use it.

NOTE that although you may restrict the bands on your modem, it does not necessarily mean your tower, or those bands, will aggregate across those bands, or even intra-band. Many variables at play.

we826 mc7455 and thanks for the help

i can lock to band 2 or any of the others .when im unlocked and getting my best speeds it is auto connecting to band 2 with band 12 and i get real good speeds. but for some reason it likes to connect to band 4 which is really slow.and say i just lock to band 2 it is better than band 4 but nothing like if it can mix band 2 and 12 . and need the bitmask (i guess thats what it is called ) for band 2 and band 12 mixed?. coudnt seem to get the speadsheet to work

Have you tried the Spreadsheet, selecting Band 2 and Band 12 from the drop down.

Band 2 & 12.png

Take the group of bands once created in the spreadsheet and go to MODEM > MISCELLANEOUS > AT-COMMAND TERMINAL and program the group run these commands (run on line at a time).

Code: Select all

AT!entercnd="A710"
AT!BAND=10,"2 & 12",0,802
AT!BAND=10
AT!RESET
 
Give it few seconds after the last command and do a power off/power on reboot.

When the router comes back online, you can check the band settings to assure they were properly applied by running the AT Commands:

Code: Select all

AT!entercnd="A710"
AT!BAND?
Which return the 2 & 12 Group of the bands.

you typed in :

Code: Select all

AT!entercnd="A710"
AT!BAND=10,"2 & 12",0,802
AT!BAND=10
AT!RESET
One command at a time, slowly?

Then after the reboot typed:

Code: Select all

AT!entercnd="A710"
AT!BAND?
And:
Index, Name, GW Band Mask L Band Mask TDS Band Mask
0A, B2, 0000000000000000 0000000000000002 0000000000000000


OK

Can anyone tell me what AT! command would tell me what Bands my Sierra modem is detecting? Not which bands it's capable of, but which bands are available/ detectable from my tower. Thanks!

To my knowledge, the Sierra Wireless modem will not tell what bands are available on a certain tower, only want bands the modem is capable of receiving, and what bands it is currently using for its connection.

In order to find out all the usable bands in your particular area, you could lock the modem to each band one by one, do an AT!GSTATUS? status after each new lock, and look at the RSSI/RSRP signal.
If it's around -100db AND you can access the internet in a browser, then write it down as one of the usable bands.

These are all the possible bands you can try for each model:
MC7455
B1, B2, B3, B4, B5, B7, B12, B13, B17, B20, B25, B26, B29, B30, B41

EM7511
B1, B2, B3, B4, B5, B7, B8, B9, B12, B13, B14, B18, B19, B20, B26, B29, B30, B32, B41, B42, B43, B46, B48, B66

EM7565
B1, B2, B3, B4, B5, B7, B8, B9, B12, B13, B18, B19, B20, B26, B28, B29, B30, B32, B41, B42, B43, B46, B48, B66

If you don't want to try all bands, then at least try these carrier specific ones:
"*" = main bands
ATT = *2, 4, 5, 12, 14, 17, 29, 30, 46, 66
TMO = 2, *4, 5, 12, 46, 66, 71
VZW = 2, 4, 5, *13, 66
SPR = *25, 26, 41

I tried the spread sheet on my MR1100. I probably used the wrong command and for a minute I thought i'd made it bran dead. I did a hard reset, but it did not respond normally however it did come back on and was reset.

I put these three commands in one at a to. It accepted them with OK. I wanted to combine 2&12 and 2,12&66. Plus add 66 seperatley.
AT!BAND=0F,"ATT 2,12",0,3000080E
AT!BAND=0F,"ATT 2,12,66",0,3000080E
AT!BAND=0C,"B66",0,0,2

I have successfully used these commands for 2 and 12.

AT!BAND=02,"LTE B2 (1900 MHz PCS)", 0, 2
AT!BAND=04,"LTE B12 (700 MHz Lower B/C/A)", 0, 800

I input the bands I wanted into cell B-15 and copied the command from C-14.
The input was T,2,12 and T2,12,66

When I did these commands the others had successfully added were already in place.
I've been having connection issues with the AT&T tower and I thought this might help. The spread sheet is amazing as long as you use it correctly. :)

I just tried this single (AT!BAND=10,"B2",0,2)command after the reset so there were no command inputs before this.
I'm using Putty to upload commands. After this command I rebooted and what come up in the browser is the top portion of the login screen, nothing else. The screen on the MR1100 is blank. I had to reset again. My model is 2A1NAS. The spreadsheet has this model on it.

Not sure if this is possible... but my best bands are B2, B13, and B66. B2 gets great speeds be only gets picked up if I bandlock to it specifically. B66 gives me 2 in CA, one at 20mhz and 5mhz (i think there is a tower a few miles back from the good B66 tower). Can i limit to only the good B66 band and let B2 take that 3rd CA slot? This is an EM7565/WG1608 combo.

I have Sierra Wireless 7565 and I have not been able to get a CA with these 2 bands, Band 4 and 28; 4A_28A:4A,28A look like the device is capable

I own a Galaxy Note 8, and using this command *#0011# I can see my cellphone can get CA with B2 and B28, and if I move a few steps to a park near where I live, I can get LTE+ with CA B4 and B28, all this using my cellphone. However my router is a WE826-T2 and it only sees every bands here(2, 4 & 28), but it never shows any sign of Carrie Agreggation nor LTE+.

my setup is WE826-T2 and a Wireless Sierra EM7565

any Troubleshooting steps that can help me understand what is going on?

Newbie here, will these commands on the spreadsheet work with the Sierra Wireless EM7411. Sorry if this has been answered, I've been looking for several days and haven't seen it yet.

I don't think so. I think they changed something. I'll have to ask around. I generally don't band lock for my setups.

This Bloody well wonderful. Thank you Jim.

I'm getting much faster speeds now on b66/b71 (was on b41 which was not even giving me data). Getting one SCC state (was hoping for more but I guess this tower does not support or have, set it to b66,b71,b4,b12
