Consent requires a positive opt-in and not any other method of consent by default. Consent means offering people genuine choice and control over how organisations use data.

Most probably that won't work or at most not practical at all because of the following reasons:ДЎ) Where is the chip that generates 850 MHz signal? if for any reason that circuit worked, it will work by pure chance once every 1,000,000 times (should be infinity since no chips at all controls the generated signal but let's assume some luck).Дў) You didn't specify any antenna, if you meant to use a simple wire as the antenna to transmit the signal, then for a 850 MHz signal you'd need a wire length between 3.5 cm ~ 20 cm long (as a dipole wire), not sticking to such calculations makes your output signal's power is in picowatts that it can't even reach centimeters from where it was generated, that also would make A LOT of noise.ДЈ) Even if the circuit output was a great 850 MHz signal, GSM (which 850 is one of its bands) won't be affected because of frequency hopping.Д¤) If GSM was blocked, the phone jumps by default to 1G system. The European Union General Data Regulation (GDPR), regulated by the Information Commissioners Office sets a high standard for consent.
