A Wi-Fi booster, also known as a wireless range extender, is a device that helps amplify and improve your existing Wi-Fi signal in areas of your home or office where the signal is weak. It works by receiving your existing Wi-Fi signal, amplifying it, and then transmitting the boosted signal further to deliver better Wi-Fi coverage.
How does a Wi-Fi booster work?
A Wi-Fi booster connects wirelessly to your main router or access point via the 2.4GHz or 5GHz band. It then amplifies the wireless signal and rebroadcasts it using the same SSID and password as your existing network. This extended signal gives you better Wi-Fi coverage in places that were previously getting poor or no reception from your main wireless router.
Here are some key points on how a Wi-Fi booster works:
- It connects wirelessly to your existing Wi-Fi network to capture the signal.
- It amplifies the signal to make it stronger.
- It rebroadcasts and extends the amplified signal further into weak coverage areas.
- It enables better Wi-Fi coverage for more stable connections.
Wi-Fi Booster Placement
Ideal placement of your Wi-Fi booster is extremely important for optimal performance. Some guidelines on booster placement:
- Place it in an area located between your main router and weak coverage zone.
- Avoid obstacles like thick walls, metal objects, microwave, etc. which can interfere with signals.
- For large homes, install multiple boosters in different problem areas.
- Elevated central locations help scatter boosted signals deeper into weak zones.
- Experiment with placements to determine what works best.
Types of Wi-Fi signal boosters
There are 3 main types of Wi-Fi boosters designed to improve in-home wireless coverage:
- Wi-Fi range extenders – These are plug-in boosters that connect over Wi-Fi to your existing network. They amplify and rebroadcast the signals into areas that have weak or no Wi-Fi reception.
- Mesh Wi-Fi systems – Mesh systems include multiple access points that work together to blanket large spaces with strong Wi-Fi coverage. They provide seamless roaming and unified Wi-Fi through a single SSID.
- Wi-Fi repeaters – Repeaters are two-way signal boosters that capture Wi-Fi from an access point or router and retransmit it omnidirectionally for better penetration. They also receive wireless signals from devices and relay them back to the main router.
Out of these, Wi-Fi range extenders are the most affordable and simplest option for boosting weak Wi-Fi spots in a home. Mesh systems provide the best quality coverage across large spaces but cost more.
Benefits of using a Wi-Fi signal booster
Here are some of the main benefits of using Wi-Fi boosters in homes and offices:
- Expanded coverage – Boosters amplify Wi-Fi reach into dead zones with weak or no signals from your main wireless router. This gives you uninterrupted coverage across larger spaces.
