Wireless LAN Network
This chapter provides background information on wireless LAN network.
2.1 Wireless LAN Overview
This section describes the wireless LAN network terms and applications.
2.1.1 SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a
wireless network. Wireless devices must have the same SSID to communicate with each other.
2.1.2 Channel
A radio frequency used by a wireless device is called a channel.
2.1.3 Transmission Rate
When the communication quality drops below a certain level, the G-302 v3 automatically
switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more
reliable. When the communication quality improves again, the G-302 v3 gradually increases
the transmission (data) rate again until it reaches the highest available transmission rate.
Note: Actual speeds attained also depend on the distance from the AP, noise, etc.
2.2 Wireless LAN Security Overview
Wireless LAN security is vital to your network to protect wireless communications.
Configure the wireless LAN security using the Profile Security Settings screen. If you do not
enable any wireless security on your G-302 v3, the G-302 v3’s wireless communications are
accessible to any wireless networking device that is in the coverage area.
