System information

 IEEE 802.11n
New Functions Implementation (DWS-4026/DWL-8600AP)
IEEE 802.11n Channel Bandwidth
 802.11a/g uses 20MHz frequency bandwidth per channel.
 802.11n can use 40MHz channel (optional) which is consist of two 20-MHz
channels that are contiguous in the frequency domain.

With doubling channel bandwidth the data transmitting/receiving speed is

With doubling channel bandwidth
,
the data transmitting/receiving speed is
doubled.
 Due to the double channel bandwidth, there are lesser available channels
(without interference) compared with 802.11a/g.
Doubling channel
bandwidth enables higher
data rates
