Chapter 1 Getting to Know Your Device

The blue ZyAIR LED (also known as the breathing light) is on when the G-1000 v2 is on and 
blinks (or breaths) when data is being transmitted to/from its wireless stations. You may use 
the web configurator to turn this light off even when the G-1000 v2 is on and data is being 
transmitted/received.

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 
802.11i) is a wireless security standard that defines stronger encryption, authentication and 
key management than WPA. 

Key differences between WPA(2) and WEP are improved data encryption and user 
authentication.

The G-1000 v2 complies with the IEEE 802.11b wireless standards.

The IEEE 802.11b data rate and corresponding modulation techniques are shown in the table 
below. The modulation technique defines how bits are encoded onto radio waves.

The G-1000 v2, complies with the IEEE 802.11g wireless standard and is also fully 
compatible with the IEEE 802.11b standard. This means an IEEE 802.11b radio card can 
interface directly with an IEEE 802.11g device (and vice versa) at 11 Mbps or lower 
depending on range.The IEEE 802.11g has several intermediate rate steps between the 
maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as 
follows:.
