WAP stands for Wireless Access Point, which is a networking device that allows wireless devices to connect to a wired network using Wi-Fi. WAPs provide wireless network connectivity to devices such as laptops, smartphones, and tablets. They are typically used in larger environments such as offices, schools, and hotels where there is a need for multiple devices to connect to the network.
On the other hand, Wi-Fi signal amplifiers, also known as range extenders, are devices that increase the range and strength of an existing Wi-Fi signal. They are used to extend the coverage of a Wi-Fi network and improve signal strength in areas of a building that may have poor reception. They do not create a new network, but rather amplify the existing signal.
As a consumer, you generally do not need to purchase both devices to have the best internet speed. If you have a wired network already set up and need to provide wireless connectivity to devices, then a WAP is the better choice. If you have a Wi-Fi network that has areas with poor reception, then a Wi-Fi signal amplifier would be the better choice to improve coverage and signal strength. However, some newer WAPs may also have built-in range extender capabilities, so it's important to research the features of each device before making a purchase.
