How do pagers work?
Is there such a thing as an open source firmware or operating system and how are the messages transmitted to the target device?

I have a question. I wanted to ask what options there are for getting random Zoom IDs. For example, something like a reading group? What methods are there?
Pagers were basically predecessors or Alternative to mobile phones that could only receive messages. They thus worked similar to radios but had prepared an individual number with which a single or a group of receivers could be addressed.
The first pagers had only four LEDs, so only 4 states could be transmitted. The meaning of the individual LEDs was agreed in advance, e.g. “Please call a specific call number”. This was often popular with companies with outside service employees, as they were always accessible, and it was a bit cheaper than the first and second generation mobile radios at that time.

OK that a pager a device is the message can I have understood, but what does it take to infrastructure and how does the receiving device know that a message is delivered to it?
Do the pagers have a clear address in a radio network?
Is this radio network cross-country?
Are the messages encrypted?
If the messages are encrypted, which encryption system is used?
Does the system know where the recipient is located?
The pager messages are sent by their own transmitters in the UHF, VHF range or also via telephone poles.
You can’t determine the location by pager, as usual pagers are only pure recipients. There are also dialogueable pagers, but they are certainly not used in the current case, because the recipient’s location should not be recognizable.
Common pagers have no encryption.
Pagers have as little a clear address as a radio receiver.
A type of code with which the receiver is addressed is safe with in the mail. But all pagers can receive it, but only show the message when their code matches the message code.
Pager messages are also only intended for the notification of persons so that they may report back with other means, so that they should not contain directly secret information.
There are also methods for addressing whole groups of pagodas.
Thank you
