also substantially slower than the speed of light, while not the biggest factor is also slower than other forms of transmission. As you said, there is a lot of noise that needs powerful error correction to be used, such as how the Reed-Solomon code was used in deep space communication. Prepackaging information before relying on wireless communication is usually the most necessary part of any reliably complex system.
