Are you living in a place where mobile phone signal is too weak for normal and hassle free use? Or where 3G or 4G Signal barely registers on your phone when you are inside the building. Well, you’re in luck! We have the solution and all you have to do is buy and install one of our repeater kit. Install one in your home or office and you’ll get stellar signal quality in no time!.

Find one that matches your network’s frequency band and network type. You can choose from single band (i.e. GSM only or LTE Only) to multi-band kits (i.e. GSM + LTE).

Our signal repeaters for mobile phones (also called signal boosters by others – which is not) are designed and manufactured by StellaDoradus. StellaDoradus is a company based in Waterford, Ireland. They manufacture cellular and WIFI antennas for EU and USA market. The company also design and manufacture mobile phone repeaters that meets EU standards.

How it Works

  1. The antenna on your roof receives mobile signal from all networks, and sends it down the cable to the repeater.
  2. The StellaDoradus device amplifies this signal in both directions, and sends it around your house.
  3. All your devices can now communicate with this enhanced signal.

Difference Between a Signal Booster and a Signal Repeater

You might be asking “what is the difference between a booster and repeater?”

In layman’s term, they could mean no difference, and they could be used interchangeably.

But, with regard to technical differences; a booster simply amplifies a signal it receives and re-transmits it within an area. No filtering or interference control is happening in such device and often causes interference to mobile provider’s network. These devices often come cheap and usually sourced from Chinese online market places, and do not meet European Standards.

If if you’re looking to amplify your cellphone signal legally, what you should look for is a Signal Repeater. One that meets EU standards and ComReg approved.

Devices that do not meet the European Standards and technical conditions will remain illegal under the Wireless Telegraphy Act 1926 to 2009.

Beware: You could get yourself in trouble when using such devices. How so? Because mobile operators detects and searches for illegal interferences and when they did, they then contact the Communications regulator, the regulator must then find the source of the interference which is often very costly. When found, the repeater will be confiscated, and the user may be fined.

Signal Repeater on the other hand, doesn’t only receive weak signal and re-transmits, it also include interference control and filtering, thereby, allowing other spectrum users to coexists. These devices passed a series of sophisticated radio frequency tests (E.T.S.I standard) and meet the required European standards to bear the CE Mark.

CE Mark: CE marking is a certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA.

So, if you’re searching for a booster device than can be used legally in Ireland, UK or any country in Europe, then Signal Repeater is what you should look for. But not just a repeater, it should meet the technical conditions that Mobile Phone Repeaters must comply with, to be permitted.

You should look for StellaDoradus devices. These devices meets several technical conditions, that makes them ComReg approved Mobile Phone Repeaters. — Read: ComReg has permitted the use of Mobile Phone Repeaters

As of June 2018, ComReg had reached a resolution after consideration, to permit the use of Mobile Phone Repeaters. The main consideration was to help improve the mobile user experience of households and businesses in rural areas.

However, not all devices shall be considered legal and permitted in Ireland. Such devices shall meet several technical conditions and must pass several tests. The technical conditions aim to provide consumers with better indoor coverage while protecting Mobile Network Operators from unwanted interference.

If interested, you can read the full document here.

The short answer is, YES!

ComReg had set technical conditions to be met, in order for a repeater be considered legal. And the best part is, SD repeaters have met all these conditions, thus, making it legally compliant. SD devices complies with EU standards and do not cause interference on any Mobile Operator’s Network. All their devices have enhanced features that passed all the required European Radio Equipment Directives (RED) and a series of sophisticated radio frequency tests (E.T.S.I standard).

In addition, there is no need for mobile operator permission for the use of Stelladoradus repeaters in Ireland, because it has complete operator protection for; feedback detection, AGC adjustment, Uplink switch off, and Base station proximity aware feature. As been declared in their most recent “Declaration of Conformitiy” document – stating that all essential radio test suites have been carried out and that the above named products are in conformity to all the essential requirements of the 2014/53/EU RED Directives.
