SSID (Service Set Identifier) and channels
3
You need to configure the SSID and a channel to specify the wireless network you want to connect to.
 SSID
Each wireless network has its own unique network name and it is technically referred to as an SSID or
ESSID (Extended Service Set Identifier). The SSID is a 32-byte or less value and is assigned to the access
point. The wireless network devices you want to associate to the wireless network should match the
access point. The access point and wireless network devices regularly send wireless packets (referred to
as a beacon) which has the SSID information. When your wireless network device receives a beacon, you
can identify the wireless network that is close enough for the radio waves to reach your device.
 Channels
Wireless networks use channels. Each wireless channel is on a different frequency. There are up to 14
different channels that can be used when using a wireless network. However, in many countries the
number of channels available are restricted.
