interference with each other. For example, you can deploy up to three 

access points in the same area using channels 1, 6, 11. Note that 

wireless clients automatically set the channel to the same as that used 

by the Wireless Broadband Router to which it is linked. Selecting Auto 

Select enables the Wireless Broadband Router to automatically select 

an unoccupied radio channel.

HT Operation Mode — Packets from 802.11n clients are referred to as 

High Throughput (HT) Greenfield packets, in other words packets that 

can be transmitted at rates of up to 150 Mbps assuming that HT 

Channel Bandwidth is set to 20/40Mhz, see HT Channel Bandwidth next 

page. 

 Some 802.11n wireless clients may be capable of transmission rates 

of up to 600 Mbps, however the Wireless Broadband Router will only be 

able to connect to them at a maximum transmission rate of 150 Mbps.

802.11b/g packets are referred to as non-HT packets, being 

transmitted at lower throughput rates. HT mixed format frames contain 

a preamble compatible with the non-HT receivers. HT Greenfield frames 

do not contain a non-HT compatible part.  Support for HT Greenfield 

format is optional. An HT station that does not support the reception of 

an HT Greenfield format frame must be able to detect that an HT 

Greenfield format frame is an HT transmission (as opposed to a non-HT 

transmission). In this case the receiver must decode the high 

throughput signal (HT-SIG) in the packet header and determine if the 

HT-SIG cyclic redundancy check (CRC) passes. (Default: Mixed)
