Signal Boosters for Eir in Ireland
Our systems support the frequencies used by Eir in Ireland.
Weak or unreliable Eir reception can make it difficult to make calls, send messages or use mobile internet indoors. Building materials, distance from the nearest mobile mast, local terrain and network congestion can all reduce the signal that reaches your phone.
A RosenFelt mobile signal booster captures the available outdoor Eir signal, amplifies it and redistributes it inside your building. This provides stronger and more reliable mobile coverage in homes, offices, shops, warehouses and other indoor locations.

Ask for Personal AdviceEven when Eir provides good coverage in your area, the signal may struggle to reach you inside a building. Modern insulation, reinforced concrete, metal roofing, coated glass and thick walls can significantly weaken mobile signals.
Reception can also be affected by the distance to the nearest mobile mast, surrounding buildings, hills, trees and the number of people using the network. As a result, your phone may show fewer signal bars indoors than it does outside.
A RosenFelt signal booster uses an outdoor antenna to receive the available mobile signal from Eir. The booster strengthens this signal and sends it to one or more indoor antennas, providing improved coverage in the areas where you need it most.
The system works in both directions. It improves the signal received by your phone and helps your phone communicate with the outdoor mobile network. Depending on the selected model and the frequencies supported by Eir, the booster can improve voice calls, 4G data and 5G connectivity.
A mobile signal booster needs an existing outdoor signal to work. It cannot create a signal where no Eir coverage is available. In most situations, however, even a weak but usable outdoor signal can be amplified to provide significantly better indoor reception.
Before choosing a booster, check your signal outside the building and consider the required coverage area, the number of floors and the mobile services you want to improve. If you are unsure which solution is best suited, you can use our no-obligation quotation form.
