HITRON CGN2 USER'S GUIDE

Use this field to configure IEEE 802.11b/g protection.

Both 802.11b and 802.11g wireless communications

occur at the same radio frequencies. When the CGN2 is

wirelessly connected to 802.11b clients and 802.11g

clients simultaneously, the performance of the link to

802.11g clients can deteriorate due to the presence of

the 802.11b clients. Because 802.11b and 802.11g use

different modulation techniques, 802.11b clients do not

understand 802.11g's Request To Send (RTS) and

Clear To Send (CTS) messages, which ensure that each

wireless device transmits only when other devices are

not transmitting.

When B/G protection is active, the CGN2 prevents

802.11b clients transmitting over 802.11g transmissions

by first transmitting an announcement (known as a CTS-

to-Self) to 802.11b clients, stating that it intends to

transmit to 802.11g clients.

Select Auto to have the CGN2 control whether B/G



protection is active or not.

Select Always-on to use B/G protection at all times.



Select Always-off to never use B/G protection.
