Connecting Laptops wirelessly without Wi-Fi/Bluetooth

[10bbobb10]

Hi

I was wondering if there is a way of connecting Laptops wirelessly when there is no Wi-Fi/Bluetooth card available.

Are there other wireless technologies that could be available in Laptops?
Could you maybe use the Wi-Fi antennas in a different way to connect to other Laptops or even Routers? (like some older/outdated radio technology?)

I don't have a specific model in mind, just asking about Laptops in general.

Thanks

There are many USB Wifi and Bluetooth adapters available.

Why/what is the reason or meaning behind "there is no Wi-Fi/Bluetooth card available"?

Likewise why not use wired via an ad hoc network? How many laptops? What is the environment?

What is the end requirement?

IrDA since 1993. Predates Wifi by 5 years and was on 100 million devices including laptops by 2000.

It's just a theoretical question.

I recently replaced a Wi-Fi card and got curious while replacing it if there are other ways to send/receive data wirelessly or establish connections if Wi-Fi cards or Wi-Fi USB adapters were not an option.

Could the Wi-Fi antenna somehow be used to transfer data without the card or does it just turn into a useless wire in that case?

It would be just a useless wire.
It needs all the circuitry to send the signal TO the wire.
