CellPipe 7130 RG User’s Guide

This section discusses wireless LANs in depth. For more information, see the 
appendix.

802.11 Mode

Select 802.11b Only to only allow IEEE 802.11b compliant WLAN 
devices to associate with the CellPipe 7130 RG. 

Select 802.11g Only to allow IEEE 802.11g compliant WLAN devices to 
associate with the CellPipe 7130 RG. IEEE 802.11b compliant WLAN 
devices can associate with the CellPipe 7130 RG only when they use the 
short premble type.

Select 802.11n Only to only allow IEEE 802.11n compliant WLAN 
devices to associate with the CellPipe 7130 RG. This can increase 
transmission rates, although IEEE 802.11b or IEEE 802.11g clients will 
not be able to connect to the CellPipe 7130 RG.

Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g 
compliant WLAN devices to associate with the CellPipe 7130 RG. The 
CellPipe 7130 RG adjusts the transmission rate automatically according 
to the wireless standard supported by the wireless devices.

Select 802.11 b/g/n mixed mode to allow both IEEE802.11b, 
IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with 
the CellPipe 7130 RG. The transmission rate of your CellPipe 7130 RG 
might be reduced.

802.11 
Protection

Enabling this feature can help prevent collisions in mixed-mode networks 
(networks with both IEEE 802.11b and IEEE 802.11g traffic).

Select Auto to have the wireless devices transmit data after a RTS/CTS 
handshake. This helps improve IEEE 802.11g performance.

Select Off to disable 802.11 protection. The transmission rate of your 
CellPipe 7130 RG might be reduced in a mixed-mode network.

This field displays Off and is not configurable when you set 802.11 
Mode to 802.11b Only.

Preamble

Select a preamble type from the drop-down list menu. Choices are Long 
or Short. The default setting is Long. See the appendix for more 
information.

This field is not configurable and the CellPipe 7130 RG uses Short when 
you set 802.11 Mode to 802.11g Only or 802.11n Only.

Apply

Click this to save your changes back to the CellPipe 7130 RG.

Reset

Click this to reload the previous configuration for this screen.
