It didn&#x27;t affect cell reception for me, you should be able to find something that only works on 2.4&gt; and leave lower bands alone.<p>LTE uses 2.5 but it&#x27;s not that common 1900-1800 and 800-900 are still the most commonly used cellular bands.<p>I also plugged only a single window if you check which walls&#x2F;windows leak the most and plug them it should allow cell reception through.
