What Is 5G?

5G (Fifth-Generation Technology) is the newest form of signal developed to connect wireless cellular devices while providing faster speeds and connection stability. Planning for 5G began in 2008, with the first public launch taking place on 3 December 2019 in South Korea. An estimated 1.7 billion people were expected to be using 5G by 2025.

Ireland's National Digital Strategy Plan aims to increase 5G coverage to all populated areas by 2030, recognising the importance of fast, reliable connectivity for both urban and rural communities.

How Does 5G Differ From 4G?

5G operates across three bandwidth types, each offering different characteristics:

  • Low Frequency (600-900MHz): Similar to 4G range with slightly higher download speeds. Best for wide-area coverage.
  • Medium Frequency (2.3-4.7GHz): The most common 5G band, offering speeds of 100-900Mbps.
  • High Frequency (24-47GHz): Capable of speeds up to 1Gbps but short-ranged, used primarily in high-density urban areas.

In terms of speed, 4G offers a maximum of around 100Mbps download, whereas 5G can reach up to 4Gbps, with plans for 20Gbps with 5.5G technology between 2025 and 2030. 5G also supports up to 1 million devices per square kilometre, compared to 4G which supports only one-tenth of this capacity.

5G coverage in Ireland is currently focused on urban environments and their vicinities. Rural areas are gradually being included in the rollout plan.

Why the Push Towards 5G in Ireland?

There are several key reasons for Ireland's push towards 5G:

  1. The need for nationwide access to digital services, including in rural areas
  2. Maintaining Ireland's status as a European headquarters for high-tech multinationals
  3. Satisfying growing demand for online learning, streaming, remote working, and online shopping

What Is the Current 5G Situation in Ireland?

Ireland's 5G rollout has progressed through several milestones:

  • 2019: Vodafone launched 5G in five Irish cities
  • 2019: Eir launched 5G with some rural coverage
  • 2020: Three Ireland became the first nationwide 5G provider

In terms of European rankings, France and Switzerland were at the top of the list for download speeds, followed by the UK and Ireland, which ranked fourth in terms of upload speeds as well.

Government Goals

  • Availability: All homes, farms, and businesses covered by Gigabit network by 2028
  • Skills: 80% of adult population with basic digital skills by 2030
  • Security: Increase cyber-security resources
  • Public Access: 90% of public services consumed online by 2030

5G Ireland — Controversies and Concerns

As with any new technology, 5G has been the subject of some controversies and concerns:

Health Concerns

Early 2000s publications claimed that non-ionising radiation posed health risks. However, these concerns have been largely discredited by the scientific community. Claims of potential links to cancer and heart disease have been proven inaccurate.

Cyber Security Concerns

There are legitimate concerns around the risk of faster cyber-attacks and data theft due to the increased efficiency of 5G data transfer. However, security systems are evolving alongside the technology to address these risks.

There have been an estimated 61 suspected arson attacks on 5G masts across Europe, with one incident occurring in Cork, Ireland. These attacks were fuelled by misinformation and conspiracy theories rather than legitimate safety concerns.

5G Ireland — Coverage Areas and Speeds

Based on 2021 data, the fastest 5G cities in Ireland were:

Are Your Devices 5G Capable?

Not everyone needs a 5G-capable device. If you primarily use your phone for messaging, calls, emails, and light social media, 4G is perfectly sufficient. However, 5G is beneficial for regular streaming, large document access and downloads, and online gaming.

Are Your Devices 5G Capable comparison table
Device 5G Capable
Samsung A52 5G / A52s Yes
Xiaomi Redmi Note 10 5G Yes
Samsung Galaxy S20 Yes
Samsung A 22 5G Yes
Google Pixel 4A 5G Yes
Oppo A54 5G Yes
Huawei P40 Lite 5G Yes
iPhone 11 5G Yes
iPhone 12 5G Yes
Most phone models have both 5G and 4G versions. Read your phone specifications carefully before completing your purchase. Devices without 5G support will automatically downgrade to 4G when connected to 5G networks — backward compatibility is fully supported.
