h Spectral efciency. Wi-Fi systems employ a standard sometimes referred to as 802.11. The number “11” is
simply the number given to the standard by the Institute of Electrical and Electronics Engineers (the IEEE).
Modern Wi-Fi routers will allow operation employing the 802.11n mode. This mode will allow higher data rates,
but it also may consume twice the number of radio channels. If the Wi-Fi router is set to 802.11n mode, it is
best to limit Wi-Fi bandwidth to 20 MHz.
h Alternate band selection. While most Wi-Fi systems operate at 2.4 GHz, which is the same band as the
DX410 system. Most allow operation at 5 GHz. If possible, move any Wi-Fi access points and equipment to
5 GHz. This of course requires all Wi-Fi equipment to be 5 GHz capable, and most older equipment may only
allow 2.4 GHz operation. Selection of 5 GHz may also not be desirable if the Wi-Fi network is for customer
access.
