How can a wireless access point benefit me?

It really depends on what you are looking for. For instance, you could provide an entire house (and beyond) with speedy Wi-Fi access by installing an access point that would feed off your already existing Wi-Fi network. You could also provide free wireless Internet access to your customers, if you owned a business where that type of service was desirable.

Is a wireless access point the same as a wireless router?

Yes and no. A router can be an access point, but an access point can't be a router, even though it looks like one. Access points are used in networks to help with Wi-Fi dead spots and extending a wireless network. Mainstream wireless access points support Wi-Fi and are oftentimes used to reinforce public Internet hotspots and other business networks where larger buildings and spaces need wireless coverage.

How far will an access point reach?

Typically about 50 meters, or approximately 55 yards.
