Everyone always gets so excited over this. &quot;Holy cow guys, be careful! The FCC will pwn you forever if you even think about running this code!&quot;<p>A cell tower is elevated, outdoors, transmits +10 W, and runs 24&#x2F;7.<p>Your BladeRF is likely to be indoors at ground level, has an output power of about 10 mW. You aren&#x27;t going to get very far with that. You&#x27;ll likely have problems detecting the signal over 100 meters, much less connecting and using it.<p>It may be illegal, but if you aren&#x27;t causing interference you&#x27;ll have a hard time getting caught. That being said, yes. Check your local laws. If you do cause a problem and it&#x27;s tracked down to you, expect to have some serious legal issues.
