Broadband providers push gigabit speeds, but most Irish households don't need anywhere near 1Gb. Here's how to figure out what you actually need—and avoid overpaying.

Quick Answer

| Household | Recommended Speed | Monthly Cost | |-----------|-------------------|--------------| | 1-2 people, light use | 100Mb | ~€30 | | Small family (3-4) | 150-300Mb | ~€35 | | Large family (5+) | 500Mb | ~€40 | | Power users/gamers | 500Mb-1Gb | ~€45 |

Reality check: 80% of Irish households would be fine with 150Mb. Gigabit speeds are overkill for normal use.

Speed Requirements by Activity

| Activity | Speed Needed | Notes | |----------|--------------|-------| | Web browsing | 5Mb | Minimal | | Email | 1Mb | Minimal | | HD video streaming (Netflix) | 5Mb | Per stream | | 4K video streaming | 25Mb | Per stream | | Video calls (Zoom) | 3Mb | Per call | | HD video calls | 8Mb | Per call | | Online gaming | 10-25Mb | Latency matters more | | Working from home | 25-50Mb | Depends on tasks | | Large file downloads | Higher = faster | But you wait either way |

Calculate Your Household Need

Step 1: Count Simultaneous Users

How many people use the internet at the same time during peak hours (evening)?

Step 2: What Are They Doing?

Light use (browsing, email): 10Mb per person
Medium use (streaming, social media): 25Mb per person
Heavy use (4K streaming, gaming, large downloads): 50Mb per person

Step 3: Add It Up

Example household:

2 adults streaming Netflix HD: 2 × 5Mb = 10Mb
1 teenager gaming: 25Mb
1 child on YouTube: 10Mb
Background devices (phones, smart TV): 10Mb
Total: 55Mb

This household would be perfectly served by 100Mb broadband—with headroom to spare.

Why You Don't Need Gigabit

The Speed You Pay For ≠ The Speed You Use

Even with 1Gb broadband:

Netflix 4K uses 25Mb
Your devices likely can't use 1Gb over WiFi anyway
Most websites don't serve content fast enough to saturate gigabit

Where Gigabit Actually Helps

Downloading large files (games, movies): Faster downloads
Multiple heavy users simultaneously: More headroom
Uploading large files: Important for creators/professionals
Future-proofing: Ready for tomorrow's demands

Where Gigabit Doesn't Help

Streaming: 25Mb is enough for 4K
Gaming: Latency matters more than speed
Browsing: Pages load at the same speed
Video calls: 10Mb is plenty

Speed Tiers Explained

100Mb Broadband

Good for: 1-2 person households, light-moderate use Real-world use:

4 simultaneous HD streams
20+ devices connected
Video calls while streaming

Limitations: Large downloads take longer. May slow down with 4+ heavy users.

300-500Mb Broadband

Good for: Families, work-from-home, gamers Real-world use:

10+ simultaneous 4K streams
50+ devices
Multiple video calls + streaming + gaming

Limitations: Few. This covers almost all residential needs.

1Gb Broadband

Good for: Large households, power users, future-proofing Real-world use:

Virtually unlimited simultaneous use
Very fast downloads
Multiple heavy users

Limitations: Overkill for most. Your WiFi router may be the bottleneck.

2Gb Broadband

Good for: Professionals, content creators, extreme use cases Reality: Almost no residential user needs this. It's marketing more than practical benefit.

The WiFi Bottleneck

Important: Your broadband speed is only as fast as your slowest link.

Most devices connect via WiFi, not ethernet
WiFi 5 (802.11ac): ~500Mb theoretical max
WiFi 6 (802.11ax): ~1Gb theoretical max
Walls, distance, interference reduce speeds further

Practical result: Even with 1Gb broadband, your laptop might only get 200-400Mb over WiFi. Solution: Use ethernet for devices that need maximum speed (gaming PC, work computer).

Gaming: Speed vs Latency

For online gaming, latency (ping) matters more than speed.

| Factor | Impact on Gaming | |--------|------------------| | Speed (Mbps) | Minimal above 25Mb | | Latency (ms) | Critical—lower is better | | Packet loss | Very important | | Jitter | Important for competitive |

Fibre broadband typically has lower latency than cable or mobile broadband. Recommendation for gamers: Any fibre connection 100Mb+ is fine. Focus on wired ethernet connection and low latency, not maximum speed.

Working From Home

Most WFH tasks don't need high speeds:

| Task | Speed Needed | |------|--------------| | Email & documents | 10Mb | | Video calls | 10-25Mb | | VPN connections | 25-50Mb | | Large file transfers | Higher = faster | | Cloud applications | 25-50Mb |

Recommendation: 100-300Mb handles most WFH scenarios comfortably. Exception: If you regularly transfer huge files (video production, engineering), faster is better.

How to Test Your Current Speed

Use a wired connection (ethernet) for accurate results

Close other applications using bandwidth

Run multiple tests at different times

Test sites: speedtest.net, fast.com, or your provider's tool

Compare results to your plan. If you're getting significantly less than advertised, contact your provider.

Recommendations by Household Type

Single Person / Couple

Speed: 100-150Mb Provider: Pure Telecom 100Mb (€30/month)

Small Family (2 adults, 1-2 kids)

Speed: 150-300Mb Provider: Pure Telecom 500Mb (€35/month) — headroom for growth

Large Family (5+ people)

Speed: 500Mb Provider: Pure Telecom or Vodafone 500Mb

Gamers / Streamers

Speed: 300-500Mb Provider: Any fibre provider — focus on low latency

Heavy WFH / Professionals

Speed: 500Mb-1Gb Provider: Vodafone or Virgin Media for consistent speeds

Don't Overpay

| Speed | Typical Cost | Who Needs It | |-------|--------------|--------------| | 100Mb | €30-35 | Most 1-2 person households | | 500Mb | €35-45 | Most families | | 1Gb | €40-50 | Power users only | | 2Gb | €60+ | Almost nobody |

The difference between 500Mb and 1Gb is often €5-10/month—€60-120/year for speeds most people won't notice.

Summary

Most households need 100-300Mb
500Mb covers virtually all residential needs
Gigabit is overkill for normal use
WiFi is usually the bottleneck, not broadband speed
For gaming, latency matters more than speed

Don't let providers upsell you to speeds you won't use. Match your speed to your actual needs and save money.
