Generally the modem would support EDGE/E-GPRS (2G) and 3G simultaniously. In Europe, EDGE/E-GPRS is still quite popular and unlikely to be sunsetted in the next 5 years. It is a pity that many manufacturers tightly integrated the

It has been heavily advertised, but its support is inconsistent. If you are deploying devices across multiple regions, you likely want them to function the same way everywhere.

Few cellular modems commonly used in IoT support IPv6, and not all mobile network operators provide an IPv6 address. Since cellular connectivity plays a major role in the industry, IPv6 cannot be used as a blanket solution to this problem.

The issue in IoT is that most people expect to be able to control their IoT (e.g. Smart Home) devices from outside of their network. This requires you to have a central server these devices communicate with or a similar deployment on-premis

A telematics tracker in a vehicle that logistic companies use (e.g. Amazon, FedEx) is also considered as an IoT device. I don't believe that the author is talking about Smart Home appliances exclusively.

Power Saving Mode (PSM), a power-saving mechanism in LTE, was specifically designed to address such issues. It allows the device to inform the eNB (base station) that it will be offline for a certain period while ensuring it periodically wa

You don’t want to redo the handshake (which, as far as I know, is identical to TLS) every time you send a packet using DTLS. Therefore, you still need to retain state information. In my opinion, using DTLS (UDP) is considerably more nuanced

> What makes a separate cellular modem better than an internal cellular modem? When using a separate cellular modem, you can connect it to your MCU via either a USB or UART interface. In IoT applications, UART is the more common choice.

The problem(-s) described in the blog post are really acute for IoT in general, especially if you want your device to run on batteries or you have a limited data budget. > Therefore, when you try to continue talking to the server over a

Google's Geolocation Services used to charge 4$ for 1000 requests to their Cellular/Wi-Fi Geolocationing Service. Essentially you send a list of Wi-Fi MAC addresses and their associated RSSI values and get back a latitude and long

I'm not sure about the situation elsewhere, but in Lithuania, it feels like professors produce articles or tackle topics solely to check a box. Most of the content generated by universities here seems completely irrelevant and ends up

My experience is that such indifference comes with seniority. Unfortunately most people tend to try and change things outside of their control, ignoring what they can change and quickly burn out. With that said: > It's painful to wo

It's surreal to imagine most companies not being able to handle a 45-min service outage of a VCS to begin with. Sounds to me like a GitHub mandated break for all SE 's.

The costs would be trivial for the vast majority of Software Engineering companies. Talking about corner cases is useless as they often need a custom specialized solution anyways and wouldn't be using GitHub in the first place.

If you're collaborating with a small group of people (or you're not running a huge amount of CI/CD) then you can make almost anything work. Once you get big it's another story entirely.

What's the point of having a mirror? It'll only lead to conflicts that'll be difficult to resolve once the main service you use is back up again. For example, I doubt you would be able to easily merge any pull-requests or use

There is no reason to host 'decentralized' tools besides regulation. It's considerably cheaper to use GitHub (or other alternatives like GitLab) than hosting your own and hiring people to maintain and support the solution. Th

Safety Critical Components (ECM, ABS, etc) need to be certified. This is very expensive and modifications are done very infrequently. I doubt that auto-manufacturers will use Embedded Linux for them.

Furthermore, unlike in the United States, we pay a significant amount of taxes. Let's say you earn €5000 per month. From your monthly salary, you'll have deductions of 20% for income tax, 6.98% for mandatory health insurance, and

In Lithuania, a mandatory health insurance tax of 6.98% is deducted from your monthly salary. For example, if you earn €5,000 per month (chosen as it is close to the average salary in the United States), this amounts to €349 per month or €4

There are parental controls on most phones. Educating parents on how to use them is a better option than a blanket ban that'll either: a) not work or b) require you to use some digital / national ID to register.
