Hello, all!

After a very pleasant experience of getting your advice, I would like your input on another issue.

I require a reliable, MCU driven cellular module to purchase in bulk, for a single purpose: communication with a remote server over HTTPS (so SMS, audio calls, etc. are not unnecessary)

I would like your recommendation for a specific model / line of products / manufacturer

 

A basic module will do, it just should fulfill these requirements:

 

1. 4G + LTE

2. able to communicate over HTTPS with a remote server

3. preferably a reputable manufacturer and not nigh-discontinued :)

4. reliable (IoT, will be left alone far away from its handler for prolonged periods of time)

5. GPS is a plus

6. WIFI is a plus

 

Do you have any suggestions?

Thanks!

We use a nimbleLink cell modem, but you need to determine first what carrier is reliable in the area of deployment first, then choose the modem/radio compatible with that carrier!

Is LTE-M acceptable?

Nordic Semiconductor has their nRF91 LTE-M SiP in engineering sampling.

edit: new arrivals at Mouser today are two USB cellular modems (1 is LTE-M) and SIM (1 is embedded SIM) :

For decades the "goto" supplier for cellular modules has been SimCom with first SIM300 and more latterly SIM900

 

For an up to date picture of where they are now perhaps see http://en.simcom.com/

 

But also note that Amazon (never one to miss a trend!) are very keen to get into IoT mainly for the "hosting services" but to facilitate this they have solutions for the hardware side of things too.

Well, after reading about it and realizing it's exactly what I need, it is :)

OK, now that I read further on LTE-M and NB-LTE-M, I realize that I should go in an entirely new direction, as this is actually the solution I need - a low power, rarely used, data-only cellular module for IoT purposes.

Should I open a new topic, or can we just reset the course of this discussion?

I prefer the former, for the sake of future searches by other people, but I don't know if it's cool with the community's guidelines.

The cellular WAN Pycom module has a cellular module from Sequans.

Wow. SimCom's web site makes it a hard to tell the difference between their many products.

It's easy to stop breaking the 10th commandment! Break the 8th instead.

Like I say SIM300 used to be the "goto" device for this. It was superseded by SIM900 and also SIM800 (which I think  is a cost down version of the latter). When I look at the SimComm site I can't help noticing:

 

 

which may suggest that the goto device these days is actually SIM7000. With that in mind, if I now google Sim7000 it leads to:

 

https://hologram.io/5-best-cellu...

 

which looks "interesting" and now maybe gives a lead to SIM7000 competitors ?

 

This also seems to suggest you are going to be paying $50..$70 per unit perhaps?

Right now, I'm doing a project with a "Particle Electron" at http://particle.io

AT&T Nationwide NB-IoT Network is Live

by Chris Penrose

April 29, 2019

...

My team is working with our suppliers to certify $5 modules that connect devices to NB-IoT. Multi-mode modules that support both NB-IoT and LTE-M are not far behind. We currently offer pricing plans for as low as $5/year/device.

...

We expect to begin deployment of NB-IoT in Mexico later this year.

...

Canada has LTE-M :

Deployment Map | Internet of Things | GSMA

though there are wide gaps in world-wide coverage.

 

The AT&T module list is a spreadsheet that has numerous cellular modules :

IoT Devices | Modules | AT&T

...

Choosing a module from the AT&T Module Catalog saves time, while assuring ongoing network compatibility. See our AT&T IoT Technology Roadmap.

LoRa Gets Open Source Software | EE Times

Semtech courts developers as NB-IoT, Sigfox options expand

by Rick Merritt

04.30.19

...

The LoRa news came one day after AT&T announced its 4G networks in the U.S. are now enabled for NB-IoT. The company aims to certify modules costing as little as $5 and data plans as low as $5 per year per device. Costs range up to $30/year for unlimited data on devices that also support LTE-M, capable of rates of megabits per second.
