Are mobile phone repeaters legal in Ireland?

About a year ago, mobile phone repeaters that met certain technical requirements were made legal in Ireland. Comreg issued a list of manufacturers whose products would meet these requirements. The manufacturers are:

  • Stella Doradus
  • Coiler
  • Nextivity

Here is a link to Comreg’s list:

Illegal repeaters

There are many companies listed on Google pretending to be legal. They claim to be “Comreg approved”. However, these low cost repeaters shipped in from China (usually Hong Kong), are disastrous for all mobile networks in Ireland. They have no “network protections” built into them and when installed, regularly “oscillate”. These oscillations can reach the local base station tower, and knock out service for everybody in the area. Every year Comreg tracks down these offending repeaters at the request of the operators, whose towers are being affected. Recently I was asked by the mobile phone operator “Three” to replace an oscillating mobile repeater in Gorey with a Stelladoradus repeater. This repeater was oscillating and wiping out the local Three tower. Everybody in the area had reduced mobile coverage as a result, and sometimes no coverage at all. The repeater in question was from, whose repeaters are all illegal here in Ireland and across the EU. These repeaters are illegal in Ireland and across the E.U We (Stelladoradus) buy these repeaters to test in the lab, when they appear on the EU market. image2 We find that all these repeaters have no protections built into them. They all have the potential to “drown out” nearby base stations when installed. Comreg spends a lot of time and effort tracking down and confiscating these repeaters every year.  Since these repeaters are mostly coming in from outside the EU, duties and taxes need to be paid at customs. Many of the repeaters get stopped and checked at customs. When the package is found to be a repeater, it is confiscated, and a warning letter goes out to the purchaser.

Some repeaters than are illegal in Ireland
The image above is me and just some of the “illegal” repeaters we have tested.

Illegal repeaters in Ireland We test all these illegal repeaters Websites that appear prominent on Google, claiming to be “comreg approved” but are in actual fact completely illegal are:

  • (products sourced in China)
  • (products sourced in China)
  • (products sourced in China)
  • (products sourced in China)

We will add to this list if more sites appear in the future. It is difficult to sue these companies due to the fact that they are not based here in Europe. Instead,Comreg have created a list of manufacturers that make repeaters that are legal to use in Ireland. The regulator in Switzerland has also produced a list of these illegal repeaters: Here is their list: Very shortly we will be be creating a similar comprehensive list for Ireland so that customers will not be fooled by these website claiming to be “Comreg approved”.
