Open source implementation of LTE. Are patents infringed?

Question

Law in IT

For example, there is a technology for wireless transmission of information - LTE, patents for certain parts are held by various telecom companies, such as Ericsson, Nokia, Motorola. They form a consortium which, with the support of the International Telecommunication Union, publishes standards and specifications for these technologies. Thus, when an LTE module is used by a third-party company, royalties are paid to this consortium, which is somehow distributed depending on the patents used.
An abstract situation, I am implementing in software, not in hardware, an implementation of the standard, for example, an LTE base station module on OCaml and publish under the GPL license. Is this infringing the use of patents or not?
On Habré we already wrote about the 4G LTE Base Station on a regular PC
ps: There are guys who implement the GSM standard under free licenses, in C ++
ru.wikipedia.org/wiki/OpenBTS here is a description about them. The main problem was obtaining permission to use the radio frequency band during field trials.

Answer 1

Even if it is, until you start making money from it, no one will tell you anything about it.
