NEC SA3500G Instruction Manual page 4

● When using the IEEE802.11b, IEEE802.11g, IEEE802.11n
communication, wireless devices use all 2.4GHz bands, and the
band of mobile identification device can be avoided. The DS-SS and
the OFDM methods are adapted as the modulation method and the
interference distance is 40m.
● When this product is used with 2.4GHz band and the channel is set
manually, the following content is recommended.
"When using this equipment with 2.4GHz band, it is recommended
to make either ch1, ch6, and ch11 as the channel setting in order
to decrease the interference and for the improvement of frequency
utilization efficiency."
However, in order to avoid the interference with systems other than
wireless LAN, it is not limited if it is necessary to use other than
recommended 1,6,11 channels.
• When using a dual channel, there is a possibility of causing
interference to other wireless stations that use the same frequency
band.
• When dual channel is "Enable", confirm that no interference is caused
to the radio signal condition of the surrounding of other confirmed
wireless stations.
• Change the setting to "Disable" immediately when interference is
generated in other wireless stations.
2.4 : Wireless device that uses 2.4GHz band is shown.
DS/OF : The DS-SS and OFDM methods are shown.
4 : Assumed interference distance of 40m or less is shown.
■■■ : It means all bandwidth can be used and the bandwidth of mobile
identification device can be avoided.
