Wireless Network

As you learned in the Wireless Network Troubleshooting video other devices within range of a wireless access point (WAP) may interfere in a variety of ways. For example, cordless phones that transmit on 2.4 GHz band my cause interference with 802.11b and 802.11g WAP which also transmit data using the 2.4 GHz band. Well, what if there is another WAP that is in range of your WAP, will it cause interference. Possibly, for example, what if you and your neighbor both use an 802.11b or 802.11g wireless access point and the houses or apartments are close enough to cause interference. What can you do?

Well, wireless access points and wireless network adapters in the US and Canada transmit and receive data by using a 22 MHz-wide set of frequencies. These frequencies are assigned to a specific "channel" and there are eleven channels on which data can be transmitted. For example, channel 1 operates on the 2.412 GHz frequency and channel 2 operates on the 2.417 GHz frequency.
