Wireless Equipment Key Terms

Get connected by learning these wireless equipment key terms

Wireless equipment provides flexibility and versatility when configuring office and home networks. These networks also allow for a broader range of connectivity than cable. There are a variety of components that can aid in the set-up of your wireless network. The terms below will help you be better informed when designing your home or business wireless network.

 

Access point, base station

An access point allows for a wireless user to connect with a wired network. It is hardware equipment that allows for wireless communication through transmission and reception of radio signals to a local area network (LAN).
Try: Internet.com has a definition of access points.

Wireless router

A wireless router is a device that has a wireless access point, switch and router built into it. Its function is to pass packets of information to the correct destination on the network. It is a way to connect both wireless and wired equipment to the Internet.

Wireless network cards, wireless network adapters, wireless network interface cards

A wireless network card connects an actual device (for example, a laptop, computer or PDA) to the network. It can connect using different interfaces, such as through USB, PC cards, or PCI interfaces. Wireless network cards allow your laptop to communicate with a modem which, in turn, accesses the Internet.
Try: ZDNet defines wireless adapters, as well as describes the different types of adapters.

Wireless modem

A wireless modem is a device that converts digital signals from a computer into frequencies that will travel over either telephone, cable or DSL (digital subscriber line). It sends the signal from your computer to allow communication with your Internet service provider.

Wireless antenna, WIFI antenna

A wireless antenna helps to extend the range of the wireless local area network (LAN). It allows you to access your wireless network over a broader area. While wireless access points usually have antennas built into them, a wireless antenna also can be added to your access point to amplify the signal strength even farther.
Try: RadioLabs will help you decide which WIFI antenna is best for you.

Repeater

A wireless repeater repeats the signal being broadcast from a wireless access point. A computer that is too far away from the access point can use a wireless repeater to access the network (as opposed to using a more powerful wireless antenna).
