How to connect a team of 5 on an open channel without a walkie-talkie?

I found that I can use Lora wireless tranceiver but I want a guaranteed way because I live in Lebanon, and I don't have any source of these equipment, so I need a working way to make the order and build my project here.

Thank you

Wow, you want to work with spread spectrum communication and four other people.

There are limits what encoding is lawful in the US and I would suspect it may be dangerous for your life in Lebanon to be doing this kind of LORA wireless.

Anyway this company is offering free samples of the necessary IC, if you are expertly able to work with electronics
