As 5G networks quickly grow across the UK, many users ask: will a 4G signal booster work with 5G? This article discusses the differences of 4G and 5G technologies, when a 4G booster may improve 5G reception, and what to keep in mind when upgrading your device.
Getting to know 4G and 5G signal boosters
A 4G signal booster is a device that intensifies 4G LTE signals to provide better indoor or vehicle cellular experiences. It consists of:
- An external antenna that picks up poor signals from the closest base stations.
- An amplifier that makes these signals stronger.
- An internal antenna that sends the amplified signal within your home, office, or car.
A 5G signal booster works similarly but supports higher bands and more advanced technologies of 5G networks, such as multiple input, multiple output (MIMO) and beamforming.
Will 4G signal boosters work with 5G?
The answer to this query relies on the frequency bands a booster is able to support and the bands your mobile network operator (MNO) offers.
- 4G frequencies in the UK commonly generally encompass 800 MHz (Band 20), 1800 MHz (Band 3), and 2100 MHz (Band 1).
- 5G frequencies span low-band (e.g., 700 MHz), mid-band (e.g., 3500 MHz, Band n78), and high-band mmWave (24 GHz and above).
If your 4G booster supports overlapping bands of your carrier’s 5G frequencies, such as 700 MHz or 1800 MHz, it can amplify those 5G signals. But, it can’t boost higher frequency 5G bands like 3500 MHz or mmWave, which needs specific 5G devices.
Compatibility overview
| Frequency Band | Technology | Typical UK Use | Can 4G Booster Amplify? |
|---|---|---|---|
| 700 MHz (Band 28) | 4G & low-band 5G | Rural and wide coverage | Yes (if supported) |
| 800 MHz (Band 20) | 4G | Rural coverage | Yes |
| 1800 MHz (Band 3) | 4G & mid-band 5G | Urban and suburban areas | Yes (if supported) |
| 2100 MHz (Band 1) | 4G | Urban areas | Yes (if supported) |
| 3500 MHz (Band n78) | 5G mid-band | Most UK 5G urban deployments | No |
| 24-39 GHz (mmWave) | 5G high-band | Limited urban hotspots | No |
How 4G boosters can enhance 5G reception
Present-day dual-band or multi-band boosters operate over a range of frequencies, including some 5G bands. Devices like the Signal Boost 4G & 5G Nikrans BD-300GDW and 4G & 5G Signal Booster Nikrans LCD-500GDW go with both 1800 MHz (4G Band 3) and 2100 MHz (5G Band 1), which allows them to boost signals for both technologies concurrently.
This means:
- Your 4G booster might even improve some 5G signals if it has overlapping bands.
- You get better signal strength, fewer dropped calls, and faster data speeds on both 4G and 5G networks.
- Coverage inside buildings or vehicles gets drastically improved.
Disadvantages of a 4G booster for 5G
- No support for mmWave 5G
4G boosters can’t amplify ultra-high-frequency mmWave signals (24 GHz and above), which are mostly applied in limited urban hotspots. - Partial 5G coverage
If your carrier’s 5G largely relies on bands not supported by your 4G booster, you won’t see any improvements on those bands. - Future-proofing
Dedicated 5G boosters offer better long-term performance as networks evolve.
Technical comparison: 4G vs 5G signal boosters
| Feature | 4G Signal Booster | 5G Signal Booster |
|---|---|---|
| Frequency support | 4G bands (700, 800, 1800, 2100, 2600 MHz) | Supports 4G + 5G bands |
| Speed enhancement | Improves 4G LTE speeds | Improves 4G and 5G speeds |
| Coverage area | Up to several hundred square meters | Similar or larger with advanced tech |
| Device compatibility | Works with 4G devices | Works with 4G and 5G devices |
| Installation | Simple DIY or professional | Similar complexity |
| Cost | Generally lower | Higher due to advanced technology |
Installation and usage tips
- Inspect your carrier’s 5G bands before you’ve decided to buy a booster. UK MNOs like EE, Vodafone, O2, and Three utilize diverse bands in different locations.
- Keep in mind to pick a booster that covers both 4G and 5G bands relevant to your area for best results.
- Mount the outside antenna at the point where the signal is best, ensuring a clear view of the cell tower.
- Position the inside antenna centrally to provide maximum indoor coverage.
- Use quality coaxial cables and connectors to keep a signal loss to a minimum.
Conclusion: will a 4G booster work with 5G?
A 4G signal booster goes well with 5G, but only if it is able to support the appropriate 5G frequency bands used by your mobile network. Many modern boosters offer dual-band or multi-band functionality, which enhances both 4G and 5G signals, particularly in the low and mid-band spectrum. For full 5G performance, getting yourself a dedicated 5G signal booster is recommended. Always verify frequency compatibility with your carrier and choose a certified booster for the best results.
