4G boosters: the illegal temptation that doesn't fix rural coverage
Moving to a village of 100 inhabitants with half-metre-thick walls and a sliver of unstable 4G outside the house is a scenario many rural property buyers in Spain know all too well. The instinct is to look for a repeater or signal booster, but the legal reality is stubborn: these devices are illegal.
Mobile frequencies are for the exclusive use of operators, who pay multimillion-euro fees to the State. A homemade amplifier transmits on those same frequencies and can interfere with official antennas, degrading service for the whole area. The rules of the Ministry of Economic Affairs make it clear: only approved and authorised equipment is allowed, and it is not sold in electronics shops.
At 200 or 300 euros, the temptation is strong, but the fine can be far more expensive. What's more, the real problem isn't solved: the outdoor signal is weak, and a booster will only repeat it just as weakly, or generate interference.
The sensible alternative is to make the most of the fibre that does reach the village. With an operator offering VoWiFi (voice over WiFi), calls work indoors without depending on mobile coverage. A directional outdoor antenna, connected to the 4G router or the phone, can also be legal if used as a passive receiver. But a signal booster, that magic little box, is the fastest route to a penalty.
