These products support the following wireless modes.
802.11n (5 GHz)
HP refers to this mode as Pure 802.11n. When operating in this mode, the AP does not
permit non-802.11n clients to associate. Legacy clients can see the access point, and may
attempt to associate, but they will be rejected. The AP makes this determination based on
the supported rates that the client presents during its association request. If the rates do
not include any of the 802.11n (HT) rates (MCS0-MCS15), the client is not allowed to
associate.
The AP also does not use protection mechanisms (RTS/CTS or CTS-to-self when
operating in this mode). This can potentially cause problems with other APs/clients
operating on the same channel in 802.11a mode, but provides the best throughput for the
AP and its 802.11n clients.
The AP will still signal associated clients to use protection when they send data. The AP
does this via a field in the beacon that it sends. So clients sending data to the AP will use
protection, but data sent from the AP will not be protected.
Note This mode is sometimes incorrectly called Greenfield. Greenfield is an 802.11n-specific
preamble that can be used by clients and APs. HP APs do not support this preamble and
therefore do not support Greenfield mode.
When to use this mode
Use this mode when the AP is installed in an area where there is no legacy wireless traffic
on the channel that the AP will use, and all potential wireless client devices support
802.11n.
802.11n (2.4 GHz)
HP refers to this mode as Pure 802.11n. When operating in this mode, the AP does not
permit non-802.11n clients to associate. Legacy clients can see the access point, and may
attempt to associate, but they will be rejected. The AP makes this determination based on
the supported rate set that the client presents during its association request. If the rate set
does not include any of the 802.11n (HT) rates (MCS0-MCS15), it is not allowed to
associate.
