When tech writers write about things they don't understand, they tend to omit all the caveats, like "cripplingly short range" and "probably illegal to operate as a consumer device due to RFI".
- userbinator 9y agoProbably legal due to the frequencies involved, but also useless in anything but a completely radio-quiet environment (the ISM bands are specifically allocated to common interference sources --- and the only reason other wireless devices like WiFi and BlueTooth can survive there are due to processing techniques that can transmit/receive below the noise floor, like spread spectrum.)
- retSava 9y agoEven if it operates in the unlicensed freq. bands, ie ISM bands, there are still limitations to how much you may interfere with others, expressed in eg duty cycle requirements (ie not sending too long at a time) and energy levels (ie not sending too strong). That's what the FCC/ETSI/CE etc etc regulations do.
