Wi-Fi Booster vs. Extender A Wi-Fi booster is more accurately defined as a wireless range extender. It is a device that acquires an existing signal from a wireless router or wireless access point than re-broadcasts it to create a second network. A Wi-Fi extender is used to extend the coverage area of your Wi-Fi network. A Wi-Fi extender works by receiving your existing Wi-Fi signal, amplifying it, and then transmitting the boosted signal. With a Wi-Fi extender you can effectively double the coverage area of your Wi-Fi network, reaching far corners of your home or office, different floors, or even extend coverage to your yard. Number 1. There is no Wi-Fi signal in some areas of your home. These areas are called dead zones or dead spots. There the areas in your house where the Wi-Fi signal disappears completely. In some cases, you may not be able to reach the wireless router or the building function in your home is preventing the signal from passing. Number 2. The Wi-Fi speed in some areas at your home is slow. Maybe your Wi-Fi router is located in the home office upstairs, but you spend most of your time downstairs. In this case, Wi-Fi extenders will be an immediate performance improvement, allowing you to rethink how to use part of the house. Number 3. You want the fastest Wi-Fi possible. Wi-Fi boosters and Wi-Fi extenders are usually associated with filling in dead spots, but they can also be used to add faster speeds and even new features to your Wi-Fi network. By adding a booster or extender to your existing network, you can upgrade to the latest Wi-Fi technology, including 802.11 AC speeds, without the trouble of replacing your Wi-Fi router. Number 4. Your home is large. The average size of a home has nearly doubled in modern time. It's hard for a single wireless router to cover a larger home, particularly when the concrete home construction further weaken the signal. Number 5. You want Wi-Fi outside. As our reliance on Wi-Fi grows, it's natural that we want to start using it in more places, such as the screen porch in the back of the house, out by the pool in the front yard, or maybe in a detached garage. Although both Wi-Fi boosters and Wi-Fi range commonly used for a similar purpose, that is, increase your network connection and enhance Wi-Fi signal. There is a tinny edge between the Wi-Fi booster and Wi-Fi extender.
