A signal booster receives the outdoor mobile signal via an external antenna, amplifies it and distributes it indoors via one or more indoor antennas. The booster is transparent to the network — your phone connects to the operator as normal, just with a stronger signal. No SIM card, no subscription and no changes to your mobile plan are required. The booster works for all devices in range simultaneously.
Does a 3G signal booster also boost 4G?
Yes. Most of our boosters support multiple frequency bands, covering both 3G and 4G networks used in Ireland.
Does a signal booster support 5G?
Yes. Selected models support 5G frequencies used in Ireland.
Can a signal booster improve mobile internet?
Yes. A stronger signal can improve both call quality and mobile data performance.
How large an area can a signal booster cover?
Coverage depends on the model. Home boosters typically cover 300 m² (1–2 floors). Commercial models cover up to 2,000 m² across multiple floors. We can advise on the right size for your building.
Does a signal booster work in a building with thick walls?
Yes. The outdoor antenna is placed on the exterior wall or roof, where the outdoor signal is strong. The indoor antenna then distributes the boosted signal throughout the building, regardless of wall thickness.
Can I use the booster with multiple phones at the same time?
Yes. A signal booster works passively — it improves the signal for every device in range simultaneously. There is no limit to the number of phones, tablets or mobile routers that can benefit.
