Has anyone built We826-T2 with Telit/fibocom with LTE modems with success?

Post by kiskey » Fri Nov 08, 2019 5:40 pm

Hi fellow LTERS,

I would like to build a custom WE826-t2 router with Telit LN940A9 / fibocom L860-GL as they are cheaper than sierra wireless and also they are with higher Cat 11/16 range.

If someone has built successfully pls point me to right direction or material. that would be great helpfull.

Not sure if OpenWRT firmware has drivers for Telit or Fibocom modems, so unless someone confirms that there are working drivers for those modems, it's probably best to stick with the true and tried Quectel or Sierra modems.

A a friend of mine is using a WG3526 with the latest Quectel EM20 CAT-20 modem via an M.2 to Mini-PCIe adapter.
This modem supports pretty much all worldwide bands B1/B2/B3/B4/B5/B7/B8/B12/B13/B14/B17/B18/B19/B20/B25/B26/B28/B29/B30/B38/39/B40/B41/B42/B43/B46/B48/B66, and it's only missing band 71 which is used by Tmobile US. Now, just because it has an incredible CAx7, depending on the carrier it may not achieve the full 2Gbps, but it can pull a couple of hundred Mbps on 4G-LTE-A. At the current price of $250 it's not cheap, but anyone who's looking for great band coverage and high speed CA, this might just fit the bill. ;)

I'm super interested in the telit/fibocom/quectel options out there.

Could your friend post up the At! commands they utilized to set up their quectel EM20?

I was going to ask the same thing, but different modem. Any experience from the group using a foxconn T77W968? this is supposed to be an m.2 modem card for dell laptops. it has a Qualcomm Snapdragon X20 in it and rated CAT16. I am more than willing to put in the money for something like this and max out my LTE speed. Would be a good investment in the long run I think.

As suggested by JimHelms, this thread over at GL-Inet is chuck full of great info about Quectel modem setup. The EM20, EC21/EC25 practically use the same AT command set, you just can't set the additional bands of the EM20 on the EC21/25 (gotta stay within your band limitations). The most important thing you have to do is set the correct APN of your carrier in the router's settings, the rest you can leave alone unless you want to lock in/lock out certain bands.

I just received mine the last few days. It works out of the box even my Verizon voice sim works with it when my EM7511 (tried with VZW and Generic firmware) doesn't. Sprint also works on it which is what I am currently using it for B41+B41+B41. Will see how stable it is as my EM7511 had a 15 day uptime before disconnect with modemmanager. ROOter will work with the modem but you need the latest fixes for your specific router if firmware is not already posted here http://www.ofmodemsandmen.com/upload/ I believe. My advice is to try to get the production version of the card because it will most likely have comm ports available for AT commands (no official document but most commands from Telit LN940 a.k.a T77W676 will work). I also bought it due to its value, Qualcomm chip, wide range of available bands to switch provider if need to, and CAT16 4x4 MIMO. It saved me money from buying the Telit LM960 I had initially wanted.

Both the Sierra EM7511 (CAT-18) and Quectel EM20 (CAT-20) are great modems with the new band 14 included, which the EM7565 is lacking.
Unfortunately they are all missing band 71 which is important if running on Tmobile US with their new 600Mhz band (5Mhz bandwidth). Here are the bands you get with the EM7511/EM7565(-band 14)/EM20:
B1, B2, B3, B4, B5, B7, B8, B9, B12, B13, B14, B18, B19, B20, B26, B29, B30, B32, B41, B42, B43, B46, B48, B66

As pricey as the Telit LM960 (CAT-18) may be, it's still the "Cadillac" of all modems, having all the above bands plus both 14 and 71. Course, if you're not running on Tmobile US, then other modems are fine too.

As an oddity, the Quectel EC25-AF does have band 71, but it's only a CAT-4 modem so no CA (carrier aggregation) available. The EP06-A is a good middle ground CAT-6 modem with all the essential US bands:
B2/B4/B5/B7/B12/B13/B25/B26/B29/B30/B66

That's in a nutshell, just wait till you see the prices on the new 5G modems (better take some heart medication first;).

The T77W968 is only missing B71 and has the features and same chip of the Telit LM960. LTE band preference (extended): '1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 38, 39, 40, 41, 42, 43, 46, 48, 66'
I won't be spending money on it unless B71 really boosts the speed in my area with T-Mobile but with only 5Mhz I don't see a significant improvement. I don't use T-Mobile but maybe after the T-Mobile/Sprint merger but 3CA B41 with MIMO 4x4 is hard to beat especially with 20Mhz each band.

5Mhz bandwidth may not sound like a lot, but the general formula to estimate a bandwidth's speed is:
(Bandwidth Mhz) * 5 = Mbps, so 5Mhz * 5 should yield about about 25Mbps under real world conditions with good signal and no congestion. Without optimum conditions the speed can be around half, however every bit of extra bandwidth could improve the speed significantly.

I've also looked into Simcom's SIM7912G-M2, which is a CAT-12 3xCA modem, in an M.2 package around $100usd.
It's a pretty attractive device with an extensive LTE band coverage rivaling Sierra's EM/MC7455 with the addition of band 66, and instead of CAT-6 it's a CAT-12 modem with 3xCA up to 600Mbps.
1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 38, 39, 40, 41, 66

Fibocom's L860-GL, M.2, CAT-16, 4xCA ain't bad either for around $150usd with the these bands:
1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 21, 25, 26, 28, 29, 30, 32, 38, 39, 40, 41, 42, 46, 66

Not sure if the Foxconn T77W968 Dell DW5821E version is locked to Dell laptops only, or it can be used freely in routers??
Being a Cat-16 with 5xCA in an M.2 package looks almost too good to be true at around $100usd with all these bands:
1, 2, 3, 4, 5, 7, 8, 12, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 38, 39, 40, 41, 42, 43, 46, 48, 66

Nope, not locked. I am using it right now in an USB enclosure connected to OpenWRT router with ModemManager. I also tested it with ROOTer with latest fixes, it works fine. It is that good of a value.
