The only shields that have been tested officially are in the Intel Edison, Galileo and Galileo Gen 2 Shields Test Report. Unfortunately there are nothing about LTE/4G in there and I'm not sure if there are shields using the XMM 7260. Do you have another option/shield for using LTE/4G?
Unfortunately no, im searching already for a week for any solution and cant find anything.
Arduino has few GSM shields but majority is just old GPRS modems with max throughput of 87kb/sec - for remote controls and commands for a drone it might be enough but not for streaming real time picture.
I find new solution from SkyWire and their 4G/LTE Arduino shield but it cost 300$ - that's damn expensive for single module.
It seems that they are also start actively targeting robo-building market and already make few interesting boards, for example this mini-PC or here is a range of boards for comparison however im not sure which one would feat my needs the most - and their dev. forum seems like no very active.
However from all that broad range of features I still cant see any board/shield with SIM slot
If you have something in mind I would be appreciate for any ideas or suggestions
a lot of the 4G/LTE usb sticks should work but i think you want to have a more compact solution. Also the kernel would need some more modules (f.e. option, usb_wwan, etc.) which are currently not included in the compiled kernel package from Yocto Linux.
Yes you right, USB stick could be compromise in this case but with more problems, not sure if I like that compromise though!
Also i'm surprised that 4G/LTE connection appears to be so rare. Technology out there already more then 2 years, and we are in Dublin have perfect - nearly full city coverage. Also there are plenty complete solutions (f.e. mentioned USB sticks from various vendors), and there are shields with GSM fro arduino, im surprised that for ~2 years nobody had needs for updating old GPRS shield with new LTE modems.
4G/LTE connection is way more handy especially for wearable devices as WiFi or BT limited to range of single spot which is incomparable to mobile network coverage.
Anyway, if you guys find about new shield/modem available for reasonable price (not 300$ for 1 module) - then please update me
No unfortunately not... still waiting for some other solution to come up.
May be Qualcomm would make available board for their new Cargo project or Intel with Arduino will get new shield... it is ridiculous to pay 300$ just for 1 module
Do you have something in mind? did you find something new?
Unfortunately not, all the shields that I have found are for GPRS or 3G , like:
Have you tested this with a GPRS shield? Is significant slow for the expected behavior that you want?
I'm not sure if you have already checked here:
If you don't want to spend a lot of money you could try testing with other shields and check the speed.
Maybe using this: https://translate.google.com/translate?hl=en&sl=ja&tl=en&u=http%3A%2F%2Fqiita.com%2Fyoneken%2Fitems%2F2f6fd50bf9837cf50f… you also could get better results too.
No, unfortunately no, i still didn't buy anything.
I was doing various tests inside my mobile network and figures I should say are not great at all.
in 3G real up speed is ~0.22 mb/sec, in 4G - up stream is ~4.99 mb/sec
with such figures i defiantly need 4G and even that would be suitable only for some 420p picture streaming as for HD stream in need stable 20mb/sec which is possible for down stream but not up.
compromise here could be to record HD video internally, and for controls only stream lower resolution, but any way 4G is least what i need.
I was "shopping" in Snapdragon forum with dragon boards, and figure out that LTE modem was integrated only in snap 801, however already in 805 it is missing.
I seen Intel make some drone which they demonstrate in CES 2015 which was able to fly in the forest and successfully avoid obstacles, that was impressive... but not related to 4G.
So there are still no acceptable solution for my needs. I still cant get why its not implemented, especially for wearable devices. seem illogical to me.
I'm already considering option to find some sort of electrician who would be able to design and solder such board. Would love to do it my self but luck of knowledge, im programmer and have no clue in circuit boards design
Yes, unfortunately it's really hard to find 4G applications/shields, and the ones availables as you said are really expensive. Have you tried with the RTOS: https://translate.google.com/translate?hl=en&sl=ja&tl=en&u=http%3A%2F%2Fqiita.com%2Fyoneken%2Fitems%2F2f6fd50bf9837cf50f… Maybe you could get better results with this.
