All things pertaining to wireless and RF links
By SmartFun94
I have a question.
What is the most suitable Wireless Transceiver that can transfer data from 700m high from the sky to the ground that is suitable to used in arduino?
I'm currently on a project of making a CanSat.

Thank you for your response.

700m is the issue. That's a lot, for unlicensed. Even line of sight.
Without an amateur radio license (for higher power, more bands)...
I'd go with a transceiver for the unlicensed band of 902-928MHz (No. America and some other places) or 868MHz in the EU.
But first, choose the protocol and how to integrate it.
I recommend this

and the reliable datagram protocol.
You can use an Anarduino board that has an atmel 8 bit micro (Arduino compatible) from
or if you need more RAM/Flash and CPU, consider a Teensy 3.1 or 3.2 from or SFE. There is a piggyback PCB for using the same HopeRF radios as on Arduino boards, with the Teensy.
