Discussion Overview

The discussion centers around finding a method for wireless data transfer that is highly directional, fast, and safe for users. Participants explore various technologies and approaches that could meet these criteria, including infrared lasers and radio modems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests a low-power infrared laser as a potential solution, noting its invisibility and low risk of causing harm unless directly stared at.
  • Another participant proposes looking into radio modems as a viable option for directional data transfer.
  • A further suggestion includes using directional WiFi antennas, specifically Yagi antennas, to establish a PC-to-PC connection while ensuring data privacy through security features.
  • A participant shares a link to a resource on directional WiFi antennas, indicating that there are many options available online.
  • One participant expresses surprise at the existence of radio modems, indicating a positive reception to the suggestions provided.

Areas of Agreement / Disagreement

Participants present multiple competing views on the best approach for achieving the desired wireless data transfer, with no consensus reached on a single solution.

Contextual Notes

Participants have not fully explored the limitations or specific requirements of each proposed technology, and there may be dependencies on definitions of "directional" and "harmless" that are not clarified.

I'm looking for some sort of wireless data transfer and I need it to be very focused.

I need something similar to a TV remote, very directional, fairly long range. I'd like it to be as precise as possible and as fast as possible. I'd also like it to be as harmless as it can be, since lasers tend to hurt/annoy people.

Could someone tell me what it is that I am looking for? I know how to describe it but I'm not sure exactly what it's called or if it exists.

Thanks! :biggrin:

I would think that a low-power IR laser would be your best bet. It wouldn't annoy anyone because it can't be seen, and it's unlikely to cause any damage unless someone deliberatedly stared straight into the beam for an extended time.
 
Try a google search on radio modem.
 
Yeah, the radio modem angle may bear fruit. Also, remember that you can get pretty directional WiFi antennas, so you could just go PC-to-PC WiFi with a couple packaged Yagi antennas with decent directional gain. You use the WiFi password/security features, obviously, to keep your data private.
 
Wow, you learn something new every day! I'd never heard of radio modems before. This is some good stuff! Thank you all for your input.
