WiFi-50B

This chapter is specifically for the FortiWiFi-50B.

In a wired network, computers are connected through a series of cables that transfer information. In a wireless network, information is transferred over radio waves. There are factors which affect the transmission of data “on the air” that you must take into account when setting up a wireless network.

This section outlines the considerations for wireless networking and steps you can take to make your wireless network as efficient as possible.

This section includes the following topics:

Setting up a wireless network

Wireless Security

FortiWiFi-50B operation modes

Setting up the FortiWiFi-50B as an Access Point

Setting up a wireless network

In its simplest form, a wireless network is an Access Point communicating with one wireless device. An Access Point (AP) is a device that provides a communications hub for a wireless network. The AP and the wireless devices operate on a common radio channel. The FortiWiFi-50B acts as an AP and assigns all wireless users to the same subnet. With the proper firewall policies and routing, wireless users can communicate with users on the internal network or on an external network such as the Internet.
