> What is definition of "Open" here?

Patent unencumbered in a way that someone could make a commercially viable implementation as a "small or midsized" company, as the parent post asked. Open Source proves my point - the issue is not implementation (note - I'm not claiming implementation isn't hard, it is - I certainly know from personal experience that it is and I would never claim to be able to personally build an energy efficient 4G or 5G modem, but I don't think that raw engineering horsepower is what's holding Apple/Intel/NVidia back here).

> MediaTek, Samsung, Huawei, Spreadtrum and a few others have been shipping 4G / 5G Modem on the market for years.

The CCP effectively told Qualcomm to get lost in 2015 and Taiwan settled an antitrust agreement between them and MediaTek in 2018, so MediaTek, Huawei, and Unisoc/Spreadtrum are not good examples here. I believe the South Korean government also intervened on behalf of Samsung. Actually, the list of modem vendors you list pretty much matches exactly the list of governments who prosecuted, fined, and settled with Qualcomm for antitrust.

Doesn't this exclude all modern cellular standards then?

yes.
