Wireless Networking Basics

Your Introduction to Wifi

Whereas a wired network uses cables to connect your devices to the Internet and other networks, a wireless network uses radio waves to accomplish the same tasks. Businesses can benefit greatly from the convenience a wireless network offers. Employees can access your network from laptops or other mobile devices from anywhere within your coverage areas. Additionally, the installation will be simpler due to the fact that there will be no need to sting cables to connect every computer to the network. This also means that the installation will be more cost effective because the cost of wiring can be reduced or even eliminated.

How a Wireless Network Works

A wireless network uses radio waves to send and receive data, just as televisions, radios and cellular phones. A wireless adapter translates data into a radio signal and transmits it through an antenna. A wireless router then receives the signal and decodes it. The router then sends the information to the Internet using a physical, wired Ethernet connection. This also works in reverse. The wireless router can receive information from the Internet and translate it into a radio signal, which is then sent to the computer's wireless adapter.

A wireless router allows you to use wireless signals or Ethernet cables to connect your computers and mobile devices to the Internet, as well as to a printer or to one another. Most routers provide coverage for a certain distance in any direction. However, walls or other physical obstructions can impact your wireless signal. Additionally, more than one router may be necessary in order to ensure you have adequate coverage for your business needs.

Wireless Site Surveys

When considering a wireless network, you will first want to ensure that all of your computers and devices are wireless enabled. Most new laptops will already have built-in wireless capability. If not, you can install a wireless network adapter card, which is typically inexpensive. Next, you should have a wireless site survey done in order to get the most out of your wireless network. A wireless site survey will plan and design a wireless network that works best for your space and number of devices connected to it. Our engineers will conduct a survey that will help rank data rates, network capacity, roaming capabilities, and many other important details that can affect connectivity. Our network engineers will come to your location and map out a plan of action. We will keep you updated on every detail as our technicians compute the very best locations to place access points. This process can aid in reducing dead zones, service shadows, and overall downtime. We can also determine the best number of access point so that your employees will not experience a slow network connection.
