HITRON CGN2 USER'S GUIDE
Use this field to configure how the CGN2 transmits in
IEEE 802.11n mode.
Mixed mode, on the other hand, allows 802.11a/b/g
stations to tell when 802.11n transmissions are
occurring, by transmitting RTS, CTS and CTS-to-Self
messages in a format the legacy stations can
understand. You should select this option if you have
802.11a/b/g stations in your networks, or if there are
other 802.11a/b/g networks in your area.
Green Field, also known is High Throughput (HT) mode,
assumes that there are no existing IEE 802.11a/b/g
stations using the same radio channel. In greenfield
mode, the 802.11a/b/g stations are unable to tell when
802.11n transmissions are occurring. You should select
this mode only if there are no 802.11a/b/g stations in
your network (or other networks in your location).
Otherwise these stations' wireless transmissions will
interfere with your 802.11n transmissions. When no
802.11a/b/g stations are present, greenfield mode
allows greater wireless network speeds, because the
legacy messages (RTS, CTS and CTS-to-Self) do not
need to be sent.
This field allows you to configure the width of the radio
channel the CGN2 uses to communicate with its
wireless clients (IEEE 802.11n only). Using the full
40MHz bandwidth can double your data speed.
Select 20 to only use a 20 megahertz band.

Select 20/40 to use a 40 megahertz band when

possible, and a 20 megahertz band when a 40Mhz
band is unavailable.
