Chapter 6. RF Link Test Chapter 6. RF Link Test The RF Link Test is a site survey tool primarily for testing RF transmissions between access points used for bridging Ethernet networks. It can also be used for checking RF paths to mobile units. The RF Link Test is only available with an Intel PRO/Wireless 2011 LAN Access Point that has been upgraded with the latest firmware. To obtain the latest firmware, go to the Intel support website. The example in Figure 6-1 shows two access points providing a wireless bridge between buildings. The RF Link Test tests the quality of the wireless link so that you can position the directional antennas for optimum signal transmission. This operation is covered later in 6.6: Using RF Link Test to Align Directional Antennas.

It consists of two access points communicating through a wireless access point link with one access point connected to a computer through a serial connection. The RF Link Test displays a special screen called Connection Quality Test that displays a bar graph showing the signal strength received from the remote access point. The computer may also connect to the local access point through a Telnet connection. This is covered in section 6.4.1: Running the RF Link Test with Telnet. 22 Configuring Access Point Bridging and Repeating (WLAP Mode)
