Channel bandwidth for Cat-M is 1.4 MHz. You won't be doing any decoding w/ a tinySA either.

It'd be cheaper to buy an RTL-SDR and an LTE antenna than this tinySA. I'm not convinced that a layman would have enough practical experience with radio's to detect these signals though. The bands used for IoT aren't exc

It would be nice to have an opt-in platform where you could select products that you'd like to see ads for. For example, you're looking for a TV or automobile and you want to see deals related to those products.

Equipment that isn't controlled by software is also prone to failure. Unintentional airbag deployment is a very rare phenomenon.

The OBD2 port is behind a gateway so it is not the same.

Because there are regulations for the infotainment system as well. For example, you can't watch videos or read SMS/messages. Not to mention that the infotainment system likely has access to the CAN bus, through which you _could_ i

You're part of a small minority of people that want to had old and outdated _infotainment_ systems. The only exception to this is that people want to have climate control knobs and buttons for some features (e.g. heated seats, driving-

I don't understand the reasoning you are making here. Cars have had advanced safety features like emergency breaking for a long time now (e.g. Toyota Crown Majesta 2003). Furthermore, there are many safety features that are controlled

The more premium Opel Astra K models had a phone holder built-in (optional accessory, but you get the point) that would also charge the phone. Practically no one bought it so they removed it in later models.

If you don't turn on the LTE chip, it can take a while to get registered or a network in order to perform an emergency call. If the LTE module is turned on (the same applies for mobile phones) the network operator will know your coarse

I've been using Apple CarPlay on a car that was manufactured in 2016. There are some occasional issues with the infotainment system, but CarPlay works as well as it did nearly 10 years ago. It is much more likely that CarPlay will cont

They have a geolocation API that allows searches of locations based on BSSID's and RSSI's and cell towers. It is "public" but you need to pay <y> $ per <x> requests.

Hilariously, the PPP (Point-to-Point Protocol) is still used in modern IoT modules. It is actually the only way to run your own TCP/IP stack (and maintain control over TLS), as not all modules support QMI or MBIM.

I guess it makes sense as Emergency Calls are highly regulated. It still applies for normal calls though. I guess this is why major smartphone operating systems do not allow you prevent 2G/3G registration.

If you force 4G and 5G only, you are likely to lose access to mobile calls. VoLTE interoperability is still lacking, and this issue is unlikely to be resolved without intervention from a standards organization mandating interoperability and

I don't understand this line of reasoning. If you build a product that is too expensive to be competitive, nobody is going to buy it. You will not earn money and will not be able to pay workers salaries. What is controversial in this s
